| |
| − | | |
| − | Containers are a solution to the problem of how to get software to run reliably when moved from one computing environment to another. This could be from a developer's laptop to a test environment, from a staging environment into production, and perhaps from a physical machine in a data center to a virtual machine in a private or public cloud.
| |
| − | | |
| − | Problems arise when the supporting software environment is not identical. For example: "You're going to test using Python 2.7, and then it's going to run on Python 3 in production and something weird will happen. Or you'll rely on the behavior of a certain version of an SSL library and another one will be installed. You'll run your tests on Debian and production is on Red Hat and all sorts of weird things happen."
| |
| − | | |
| − | And it's not just different software that can cause problems, he added. "The network topology might be different, or the security policies and storage might be different but the software has to run on it."
| |
| − | | |
| − | '''How do containers solve this problem?'''
| |
| − | Put simply, a container consists of an entire runtime environment: an application, plus all its dependencies, libraries and other binaries, and configuration files needed to run it, bundled into one package. By containerizing the application platform and its dependencies, differences in OS distributions and underlying infrastructure are abstracted away.
| |
| − | | |
| − | Containers offer a logical packaging mechanism in which applications can be abstracted from the environment in which they actually run.

| |
| − | | |
| − | The Cloud SDK is a set of tools for Cloud Platform. It contains [https://cloud.google.com/sdk/gcloud/reference/ '''gcloud'''], [https://cloud.google.com/storage/docs/gsutil '''gsutil'''], and [https://cloud.google.com/bigquery/docs/bq-command-line-tool '''bq'''], which you can use to access Google Compute Engine, Google Cloud Storage, Google BigQuery, and other products and services from the command-line. You can run these tools interactively or in your automated scripts. A comprehensive guide to gcloud can be found in [https://cloud.google.com/sdk/gcloud/ '''gcloud Overview'''].

| |
| − | : Access scopes:
| |
| − | :* Allow default access: Activada por defecto...
| |
| − | :* Allow full access to all Cloud APIs
| |
| − | ::* <span style="background:#00FF00">Es apropiado marcar esta opción.</span> Si no se marca no se podrá, por ejemplo, copiar files desde una VM instance a un bucket de esta forma:
| |
| − | <blockquote>

| |
| − | </blockquote>
| |
| − | ::* <span style="background:#00FF00">Otra opción es para permitir copiar archivos desde la VM hacia un bucket es configurar la "Service account". Debemos elegir una Service Account que hayamos configurade previamente para permitir este tipo de acciones. Ver [[Cloud Computing#Service Accounts|Service Accounts]] para más detalles</span>
| |
| − | :* Set access for each API
| |
| − | * '''Firewall:'''

| − | You can connect to Linux instances through either:
| |
| − | * The Google Cloud Platform Console
| |
| − | * The gcloud command-line tool.
| |
| − | * Connecting using third-party tools
| |
| − | | |
| − | Compute Engine generates an SSH key for you and stores it in one of the following locations:
| |
| − | * By default, Compute Engine adds the generated key to project or instance metadata.
| |
| − | * If your account is configured to use OS Login, Compute Engine stores the generated key with your user account.
| |
| − | | |
| − | | |
| − | <br />
| |
| − | =====The Google Cloud Platform Console=====
| |
| − | Esta es un Console que pertenece a la GCP a la cual se accede a travé de una Browser window. Para abrirla vamos a:
| |
| − | * In the GCP (Google Cloud Platform) Console, go to the VM Instances page.
| |
| − | * In the list of virtual machine instances, click SSH in the row of the instance that you want to connect to. | |
| − | | |
| − | | |
| − | <br />
| |
| − | =====The gcloud command-line tool=====
| |
| − | A través del comando '''gcloud''' (incluido en Cloud SDK) podemos acceder a la VM Instance desde el Terminal (Console) de nuestra computadora.
| |
| − | gcloud compute ssh [INSTANCE_NAME]
| |
| − | | |
| − | | |
| − | <br />
| |
| − | =====Connecting using third-party tools=====
| |
| − | https://cloud.google.com/compute/docs/instances/connecting-advanced#thirdpartytools
| |
| − | | |
| − | Ver [[Linux#SSH]]
| |
| − | | |
| − | También podemos acceder a una VM Instance sin necesidad de utilizar herramientas de la GCP, como lo son The Google Cloud Platform Console or gcloud. Podemos, en su lugar, utilizar '''SSH'''.
| |
| − | | |
| − | Luego de crear una VM Instance, no podremos acceder a la VM a través de SSH debido a que ningún método de autentificación estará disponible. Como explicamos en [[Linux#SSH]]. Hay dos approach para la autentificación al usar SSH:
| |
| − | | |
| − | * '''Using the password de la «cuenta linux»:'''
| |
| − | :* Las Google Cloud VM Instance se crean por defecto sin password. Además, en la configuración por defectos de las Google VM Instance, se impide la autentificación con password. Es decir, el archivo «/etc/ssh/sshd_config» presenta la siguiente configuración: «PasswordAuthentication no».
| |
| − | :* Entonces, tenemos primero que encontrar otro método de acceder a las GC VM para:
| |
| − | ::# Configurar «PasswordAuthentication yes»
| |
| − | ::# Configurar un password para el user@VMInstance
| |
| − | | |
| − | * '''SSH Keys:''' Si queremos autentificar la conexión con este método tenemos primero que copiar la «public key» de nuestra computadora en las Google Cloud VM Instances.
| |
| − | :* Como se explica en [[Linux#SSH]], si queremos hacerlo con el comando «ssh-copy-id» tenemos primero que configurar una password para el user@VMInstance y habilitar la autentificación a través de dicho password como explicamos arriba.
| |
| − | :* Entonces, igualmente, tenemos primero que encontrar otro método de acceder a las GC VM para poder copiar la «public key».
| |
| − | | |
| − | | |
| − | Alors, para conectarnos a las GC VM y realizar las configuraciones necesarias para permitir la conexión con SSH podemos usar el comando «gcloud» como ya hemos visto:
| |
| − | gcloud compute ssh [INSTANCE_NAME]
| |
| − | | |
| − | Cuando realizamos la primera conexión a través de «gcloud», el comando generará las keys necesarias para la conexión con «gcloud»:
| |
| − | | |
| − | [[File:SSH_google_keys.png|900px|thumb|center|]]
| |
| − | | |
| − | | |
| − | <span style="background:#D8BFD8">Lo que he constatado es que, luego de crear la GC VM, si intento ingresar con «ssh» antes de haber ingresado con «gcloud», no será posible el acceso porque no hay método de autentificación. Sin embargo, si primero me conecto con «gcloud», luego sí puedo ingresar con «ssh» sin necesidad de realizar otra configuración ni copiar la «public key». Esto me imagino que es porque, como se ve en la imagen mostrada arriba, «gcloud» ha creado las «key» y copiado la «public key» en la computadora destino; y al parecer éstas mismas funcionan con una conexión normal de ssh (sin acudir a «gcloud»). Esto lo he constatado conectandome desde mi computadora a las GC VM.</span> <span style="color:#FFF;background:#FF0000">Sin embargo, siguiendo el mismo procedimiento intenté conectarme entre dos GC VM Instances y no logré estableser la conección a través de SSH. El problema lo solucioné, siguiendo el consejo de un forum, borrando todos los archivos en «~/.ssh/» excepto «known_hosts» y generando nuevas keys (con «ssh-keygen») y copiando la nueva «public key» en la GC VM correspondiente, siguiendo los procedimientos en [[Linux#SSH]]</span>.

| |
| − | ===Copy files===
| |
| − | | |
| − | | |
| − | <br />
| |
| − | ====From the host computer to a bucket on Google Cloud====
| |
| − | Luego de crear el bucket, podemos copiar archivos al bucket. Hay diferentes formas de hacerlo:
| |
| − | * Sinple drag and drop
| |
| − | * Usando el terminal de Google cloud
| |
| − | * Desde el terminal de la computadora luego de instalar Cloud SDK
| |
| − | | |
| − | | |
| − | <br />
| |
| − | =====Desde el terminal de la computadora luego de instalar Cloud SDK=====
| |
| − | El siguiente comando copia un archivo que está en mi computadora a un bucket on GC:
| |
| − | gsutil cp probando gs://adelostorage
| |
| − | Where adelostorage is the name of the bucket.
| |
| − | | |
| − | | |
| − | <br />
| |
| − | ====From the host computer to a Linux VM Instance or between VM's====
| |
| − | https://cloud.google.com/sdk/gcloud/reference/compute/scp
| |
| − | | |
| − | To copy a remote directory, ~/narnia, from example-instance to the ~/wardrobe directory of your local host, run:
| |
| − | gcloud compute scp --recurse example-instance:~/narnia ~/wardrobe
| |
| − | | |
| − | | |
| − | <br />
| |
| − | ====From a bucket to an VM Instance====
| |
| − | Luego de acceder a una VM Instance, puedo copiar un archivo desde un bucket a dicha VM Instance a través de la siguiente orden:
| |
| − | gsutil cp gs://adelostorage/probando.txt .
| |
| − | | |
| − | | |
| − | <br />
| |
| − | ===Acceding Cloud Storage buckets===
| |
| − | He estado buscando una forma para acceder a mis Buckets de forma tal que sea posible compartir el bucket con otras personas:
| |
| − | * A través de una URL
| |
| − | * A través de un IP
| |
| − | | |
| − | En los siguientes links se explica como hacer el bucket público y como acceder a él a través de una URL:
| |
| − | * https://cloud.google.com/storage/docs/access-control/making-data-public
| |
| − | * https://cloud.google.com/storage/docs/access-public-data
| |
| − | | |
| − | Pensé que lo que se explicaba en esos links era la solución. Pero creo que eso sólo permite hacer el bucket público para todos los usuarios de un proyecto (creo); porque la URL a la que creo se refieren en dicho link es:
| |
| − | * https://console.cloud.google.com/storage/BUCKET_NAME
| |
| − | * En mi caso: https://console.cloud.google.com/storage/browser/sinfronterasbucket1
| |
| − | | |
| − | y pues ese link sólo permitiría el acceso a mi bucket al estar logeados en mi cuenta.
| |
| − | | |
| − | | |
| − | <br />
| |
| − | ====Connecting your domain to a Cloud Storage Bucket====
| |
| − | Lo que sí encontré es que hay una forma de asociar el bucket a un dominio que nos pertenezca. Por ejemplo, el siguiente subdominio lo voy a asociar a un bucket:
| |
| − | * www.es.sinfronteras.ws
| |
| − | * https://console.cloud.google.com/storage/browser/www.es.sinfronteras.ws
| |
| − | | |
| − | En el siguiente link se explica como connect your domain to Cloud Storage and Hosting a Static Website en el Bucket: https://cloud.google.com/storage/docs/hosting-static-website
| |
| − | | |
| − | | |
| − | <br />
| |
| − | ===Mounting Cloud Storage buckets as file systems===
| |
| − | Cloud Storage FUSE: Mounting Cloud Storage buckets as file systems on Linux or OS X systems:
| |
| − | https://cloud.google.com/storage/docs/gcs-fuse
| |
| − | | |
| − | Cloud Storage FUSE is an open source FUSE adapter that allows you to mount Cloud Storage buckets as file systems on Linux or OS X systems.
| |
| − | | |
| − | | |
| − | <br />
| |
| − | ====Installing Cloud Storage FUSE and its dependencies====
| |
| − | https://github.com/GoogleCloudPlatform/gcsfuse/blob/master/docs/installing.md
| |
| − | | |
| − | * Add the gcsfuse distribution URL as a package source and import its public key:
| |
| − | <blockquote>
| |
| − | <syntaxhighlight lang="bash">
| |
| − | export GCSFUSE_REPO=gcsfuse-`lsb_release -c -s`
| |
| − | echo "deb http://packages.cloud.google.com/apt $GCSFUSE_REPO main" | sudo tee /etc/apt/sources.list.d/gcsfuse.list
| |
| − | curl https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -
| |
| − | </syntaxhighlight>
| |
| − | </blockquote>
| |
| − | | |
| − | * Update the list of packages available and install gcsfuse:
| |
| − | <blockquote>
| |
| − | <syntaxhighlight lang="bash">
| |
| − | sudo apt-get update
| |
| − | sudo apt-get install gcsfuse
| |
| − | </syntaxhighlight>
| |
| − | </blockquote>
| |
| − | | |
| − | * (Ubuntu before wily only) Add yourself to the fuse group, then log out and back in:
| |
| − | <blockquote>
| |
| − | <syntaxhighlight lang="bash">
| |
| − | sudo usermod -a -G fuse $USER
| |
| − | exit
| |
| − | </syntaxhighlight>
| |
| − | </blockquote>
| |
| − | | |
| − | * Future updates to gcsfuse can be installed in the usual way:
| |
| − | <blockquote>
| |
| − | <syntaxhighlight lang="bash">
| |
| − | sudo apt-get update && sudo apt-get upgrade
| |
| − | </syntaxhighlight>
| |
| − | </blockquote>
| |
| − | | |
| − | | |
| − | <br />
| |
| − | ====Set up credentials for Cloud Storage FUSE====
| |
| − | Cloud Storage FUSE auto-discovers credentials based on application default credentials:
| |
| − | * If you are running on a Google Compute Engine instance with scope storage-full configured, then Cloud Storage FUSE can use the Compute Engine built-in service account. For more information, see Using Service Accounts with Applications.
| |
| − | ** <span style="background:#D8BFD8">Si se está usando una Google Compute Engine Instance, no se tiene que hacer nada para montar el Bucket. Sin embargo si el Access scopes de dicha Instance no fue configurado correctamente, entonces no podremos copiar arechivos desde la Instance hacia el Bucket montado. Ver en la [[Cloud Computing#Crear una VM Instance|creación de la VM Instance]] que es apropiado elegir "Allow full access to all Cloud APIs" o elegir una Service Account que hayamos configurade previamente para permitir este tipo de acciones. Ver [[Cloud Computing#Service Accounts|Service Accounts]] para más detalles.
| |
| − | </span>
| |
| − | | |
| − | * If you installed the Google Cloud SDK and ran gcloud auth application-default login, then Cloud Storage FUSE can use these credentials.
| |
| − | | |
| − | * If you set the environment variable GOOGLE_APPLICATION_CREDENTIALS to the path of a service account's JSON key file, then Cloud Storage FUSE will use this credential. For more information about creating a service account using the Google Cloud Platform Console, see Service Account Authentication.
| |
| − | | |
| − | | |
| − | <br />
| |
| − | ====Mounting a Google Cloud Storage Bucket as a local disk====
| |
| − | * Create a directory:
| |
| − | mkdir /path/to/mount
| |
| − | | |
| − | * Create the bucket you wish to mount, if it doesn't already exist, using the Google Cloud Platform Console.
| |
| − | | |
| − | * Use Cloud Storage FUSE to mount the bucket (e.g. example-bucket).
| |
| − | gcsfuse example-bucket /path/to/mount

| − | https://stackoverflow.com/questions/21065922/how-to-open-a-specific-port-such-as-9090-in-google-compute-engine
| |
| − | | |
| − | Por defectos, sólo el puerto tcp:80 se encuentra abierto. Los otros están protegidos por los firewalls. Si configuramos, por ejemplo, un Web Server (Apache, NGINX) en un puerto distinto al 80, debemos modificar los Firewall Rules para que el Web Server sea capaz de servir las páginas a través de otro puerto.
| |
| − | | |
| − | '''Para abrir un puerto:'''
| |
| − | * Choose you Project: al lado del Main Menu (burguer)
| |
| − | * Then, go to: Burguer > VPC network > Firewall rules:
| |
| − | ** Create a firewall rule
| |
| − | | |
| − | Luego, seguir los pasos indicados en: https://cloud.google.com/vpc/docs/using-firewalls:
| |
| − | Con las siguientes especificaciones (el resto en default) he sido capaz de hacerlo:
| |
| − | * Targets
| |
| − | ** All instances in the network
| |
| − | * Source IP ranges:
| |
| − | ** If you want it to apply to all ranges, specify 0.0.0.0/0

| |
| − | https://cloud.google.com/iam/docs/granting-roles-to-service-accounts
| |
| − | | |
| − | Por ejemplo, para poder copar arvhivos desde VM Instance hacia un Bucket, you need to Setting up a new instance to run as a service account. Dicha service account tiene que haber sido Granted with the particular Roles que permiten dicha operación de copia.
| |
| − | | |
| − | To grant the roles, no puede hacerlo a través de la línea de comandos pues me generó un error. Lo pude sin embargo hacer desde la página de GCP. para la operación de copia descrita arriba hay que agregar a la service account en la cual corre la VM los roles relacionados con Storage:
| |
| − | * Storage Admin
| |
| − | * Storage Object Admin
| |
| − | * Storage Object Creator
| |
| − | * Storage Object Viewer
| |
| − | | |
| − | Luego de haber creado la Service Account podemos, al momento de crear la VM Instance, ajustar que la new instance runs as this service account (ver ).

| |
| − | ====Compute====
| |
| − | | |
| − | :*'''Amazon Elastic Compute Cloud (EC2)'''
| |
| − | ::*EC2 is essentially a computer in the cloud. EC2 is a Web Service that provides compute capacity in the cloud (Virtual computing environment in the cloud).
| |
| − | ::*EC2 allows you to create and configure virtual compute capacity.
| |
| − | ::*'''Elastic''' refers tot the fact that if properly configured, you can increase or decrease the amount of servers required by an application automatically, according to the current demands on that application.
| |
| − | ::*'''Compute''' refers to the compute, or '''server''' resources that are being presented.
| |
| − | | |
| − | | |
| − | :*'''AWS Lambda:'''
| |
| − | ::*AWS Lambda is an event-driven, serverless computing platform. It is a computing service that runs code in response to events and automatically manages the computing resources required by that code.
| |
| − | ::*AWS Lambda lets you run code without provisioning or managing servers. You pay only for the compute time you consume - there is no charge when your code is not running.
| |
| − | ::*The purpose of Lambda, as compared to AWS EC2, is to simplify building smaller, on-demand applications that are responsive to events and new information. AWS targets starting a Lambda instance within milliseconds of an event. Node.js, Python, Java, Go[2], Ruby[3] and C# (through .NET Core) are all officially supported as of 2018. In late 2018, custom runtime support[4] was added to AWS Lambda giving developers the ability to run a Lambda in the language of their choice.
| |
| − | | |
| − | | |
| − | :*'''Auto Scaling:'''
| |
| − | ::*Scales EC2 capacity as needed
| |
| − | ::*Improves availability
| |
| − | | |
| − | | |
| − | :*'''Elastic Load Balancer:'''
| |
| − | ::*Elastic Load Balancing automatically distributes incoming application traffic across multiple targets, such as Amazon EC2 instances, containers, IP addresses, and Lambda functions. It can handle the varying load of your application traffic in a single Availability Zone or across multiple Availability Zones.
| |
| − | | |
| − | | |
| − | :*'''AWS Elastic Beanstalk:'''
| |
| − | ::*AWS Elastic Beanstalk is an easy-to-use service for deploying and scaling web applications and services developed with Java, .NET, PHP, Node.js, Python, Ruby, Go, and Docker on familiar servers such as Apache, Nginx, Passenger, and IIS.
| |
| − | | |
| − | :::You can simply upload your code and Elastic Beanstalk automatically handles the deployment, from capacity provisioning, load balancing, auto-scaling to application health monitoring.
| |
| − | | |
| − | | |
| − | <br />
| |
| − | ====Storage====
| |
| − | | |
| − | :'''There are three broad categories of storage:'''
| |
| − | ::*'''Instance storage:''' Temporary storage that is added to your Amazon EC2 instance
| |
| − | | |
| − | | |
| − | ::*'''Amazon Elastic Block Store (Amazon EBS):''' It is persistent, mountable storage, which can be mounted as a device to an Amazon EC2 instance. Amazon EBS can only be mounted to an Amazon EC2 instance within the same Availability zone.
| |
| − | | |
| − | :::Each Amazon EBS volume is automatically replicated within its Availability Zone to protect you from component failure, offering high availability.
| |
| − | | |
| − | :::* '''Uses:'''
| |
| − | ::::*Boot volumes and storage for Amazon EC2 instances
| |
| − | ::::*Data Storage with a file system
| |
| − | ::::*Database hosts
| |
| − | ::::*Enterprise applications.
| |
| − | | |
| − | :::* '''Volume types:'''
| |
| − | ::::*Solid-State Drives (SSD)
| |
| − | ::::*Hard Disk Drives (HDD)
| |
| − | | |
| − | | |
| − | ::*'''Amazon Simple Storage Service (Amazon S3):''' Similar to Amazon EBS. It is persistent storage; however, it can be accessed from anywhere.
| |
| − | :::* Object level storage
| |
| − | :::* Amazon S3 con even be configured to support corss-region replication such that data put into an Amazon S3 bucket in one region can be automatically replicated to another Amazon S3 Region.
| |
| − | | |
| − | :::* '''Uses:'''
| |
| − | ::::* Storing application assets
| |
| − | ::::* Static web hosting
| |
| − | ::::* Backup and Disaster Recovery (DR)
| |
| − | ::::* Staging area for big data
| |
| − | | |
| − | | |
| − | | |
| − | :'''Another Storage options:'''
| |
| − | | |
| − | ::*'''Amazon Elastic File System (Amazon EFS)'''
| |
| − | ::: Provides simple, scalable, elastic file storage for use with AWS services and on-premises resources. It is easy to use and offers a simple interface that allows you to create and configure file systems quickly and easyly.
| |
| − | ::: Amazon EFS is build to elastically scale on demand withou disrupting applications, growing and shrinking automatically as you add and remove files, so your applications have the storage they need, when they need it.
| |
| − | | |
| − | | |
| − | ::*'''Amazon Glacier:'''
| |
| − | :::* Amazon Glacier is a secure, durable, and extremely low-cost cloud storage service for data archiving and long-term backup.
| |
| − | :::* Data stored in Amazon Glacier takes several hours to retrieve, which is why it's ideal for archiving.
| |
| − | | |
| − | | |
| − | ::*Amazon Relational Database Service (RDS)
| |
| − | | |
| − | | |
| − | ::*Amazon DynamoDB
| |

| |
| − | =====Block vs Object Storage=====
| |
| − | What if you want to change one character in a 1 GB file?:
| |
| − | | |
| − | *With block storage, you only need to change the block that contains the character.
| |
| − | *With object storage, the entire file must be updated.
| |
| − | | |
| − | This difference has a mejor impact on the throughput latency, and cost of your storage solution. Block storage solutions are typically faster and use less bandwidth, but cost more than object-level storage.

| |
| − | | |
| − | * 54.165.65.200
| |
| − | * The second entry specifies that any traffic destined for the Internet (0.0.0.0/0) is routed to the Internet Gateway (igw-). This setting makes it a Public Subnet.
| |
| − | * Homework. Watch these videos:
| |
| − | :* Designing VPC
| |
| − | :* HA Section 1
| |
| − | | |
| − | | |
| − | Critical business systems should be deployed as Highly Available applications, meaning that they can remain operational even when some components fail. To achieve High Availability in AWS, it is recommended to run services across '''multiple Availability Zones.'''
| |
| − | | |
| − | Many AWS services are inherently highly available, such as Load Balancers, or can be configured for high availability, such as deploying Amazon EC2 instances in multiple Availability Zones.
| |
| − | | |
| − | In this lab, you will start with an application running on a single Amazon EC2 instance and will then convert it to be Highly Available.
| |
| − | | |
| − | | |
| − | '''Objectives:'''
| |
| − | | |
| − | After completing this lab, you will be able to:
| |
| − | * Create an image of an existing Amazon EC2 instance and use it to launch new instances.
| |
| − | * Expand an Amazon VPC to additional Availability Zones.
| |
| − | * Create VPC Subnets and Route Tables.
| |
| − | * Create an AWS NAT Gateway.
| |
| − | * Create a Load Balancer.
| |
| − | * Create an Auto Scaling group.
| |
| − | | |
| − | | |
| − | The final product of your lab will be this:
| |
| − | | |
| − | | |
| − | <br />
| |
| − | ====Task 1 - Inspect Your environment====
| |
| − | This lab begins with an environment already deployed via AWS CloudFormation including:
| |
| − | * An Amazon VPC
| |
| − | * A public subnet and a private subnet in one Availability Zone
| |
| − | * An Internet Gateway associated with the public subnet
| |
| − | * A NAT Gateway in the public subnet
| |
| − | * An Amazon EC2 instance in the public subnet
| |
| − | | |
| − | | |
| − | <br />
| |
| − | =====Task 1-1 - Inspect Your VPC=====
| |
| − | * On the AWS Management Console, on the Services menu, click VPC.
| |
| − | | |
| − | | |
| − | * In the left navigation pane, click Your VPCs.
| |
| − | : Here you can see the Lab VPC that has been created for you:
| |
| − | :* In the IPv4 CIDR column, you can see a value of 10.200.0.0/20, which means this VPC includes 4,096 IPs between 10.200.0.0 and 10.200.15.255 (with some reserved and unusable).
| |
| − | :* It is also attached to a Route Table and a Network ACL.
| |
| − | :* This VPC also has a Tenancy of default, instances launched into this VPC will by default use shared tenancy hardware.
| |
| − | | |
| − | | |
| − | * In the navigation pane, click Subnets.
| |
| − | : Here you can see the Public Subnet 1 subnet:
| |
| − | :* In the VPC column, you can see that this subnet exists inside of Lab VPC
| |
| − | :* In the IPv4 CIDR column, you can see a value of 10.200.0.0/24, which means this subnet includes the 256 IPs (5 of which are reserved and unusable) between 10.200.0.0 and 10.200.0.255.
| |
| − | :* In the Availability Zone column, you can see the Availability Zone in which this subnet resides.
| |
| − | | |
| − | | |
| − | * Click on the row containing Public Subnet 1 to reveal more details at the bottom of the page.
| |
| − | | |
| − | | |
| − | * Click the Route Table tab in the lower half of the window.
| |
| − | : Here you can see details about the Routing for this subnet:
| |
| − | :* The first entry specifies that traffic destined within the VPC's CIDR range (10.200.0.0/20) will be routed within the VPC (local).
| |
| − | :* The second entry specifies that any traffic destined for the Internet (0.0.0.0/0) is routed to the Internet Gateway (igw-). This setting makes it a Public Subnet.
| |
| − | | |
| − | | |
| − | * Click the Network ACL tab in the lower half of the window.
| |
| − | : Here you can see the Network Access Control List (ACL) associated with the subnet. The rules currently permit ALL Traffic to flow in and out of the subnet, but they can be further restricted by using Security Groups.
| |
| − | | |
| − | | |
| − | * In the left navigation pane, click Internet Gateways.
| |
| − | : Notice that an Internet Gateway is already associated with Lab VPC.
| |
| − | | |
| − | | |
| − | * In the navigation pane, click Security Groups.
| |
| − | | |
| − | | |
| − | * Click Configuration Server SG.
| |
| − | : This is the security group used by the Configuration Server.
| |
| − | | |
| − | | |
| − | * Click the Inbound Rules tab in the lower half of the window.
| |
| − | : Here you can see that this Security Group only allows traffic via SSH (TCP port 22) and HTTP (TCP port 80).
| |
| − | | |
| − | | |
| − | * Click the Outbound Rules tab.
| |
| − | : Here you can see that this Security Group allows all outbound traffic.
| |
| − | | |
| − | | |
| − | <br />
| |
| − | =====Task 1-2 - Inspect Your Amazon EC2 Instance=====
| |
| − | In this task, you will inspect the Amazon EC2 instance that was launched for you.
| |
| − | | |
| − | | |
| − | * On the Services menu, click EC2.
| |
| − | | |
| − | | |
| − | * In the left navigation pane, click Instances.
| |
| − | : Here you can see that a Configuration Server is already running. In the Description tab in the lower half of the window, you can see the details of this instance, including its public and private IP addresses and the Availability zone, VPC, Subnet, and Security Groups.
| |
| − | | |
| − | | |
| − | * Copy the IPv4 Public IP value and paste it into a text editor, such as Notepad. You will use it later.
| |
| − | | |
| − | | |
| − | * In the Actions menu, click Instance Settings > View/Change User Data.
| |
| − | : Note that no User Data appears! This means that the instance has not yet been configured to run your web application. When launching an Amazon EC2 instance, you can provide a User Data script that is executed when the instance first starts and is used to configure the instance. However, in this lab you will configure the instance yourself!
| |
| − | | |
| − | | |
| − | * Click Cancel to close the User Data dialog box.
| |
| − | | |
| − | | |
| − | <br />
| |
| − | ====Task 2 - Login to your Amazon EC2 instance====
| |
| − | * En este lab se descargó el archivo «labsuser.pem» de una forma particular debido a que el la genera la VPC and Instances de forma automática. Sabemos que este archivo «labsuser.pem» se optiene cuando se crea la Instance, podemos descargarlo y contiene la ssh key que permite autenticar la conexión entre nuestra computadora y la instance.
| |
| − | | |
| − | * Change the permissions on the key to be read only, by running this command:
| |
| − | chmod 400 labsuser.pem
| |
| − | | |
| − | | |
| − | * Luego para conectarnos desde el terminal:
| |
| − | ssh -i labsuser.pem ec2-user@<public-ip>
| |
| − | | |
| − | | |
| − | <br />
| |
| − | ====Task 3 - Install and Launch Your Web Server PHP Application====
| |
| − | sudo yum -y update
| |
| − | | |
| − | | |
| − | This command installs an Apache web server (httpd) and the PHP language interpreter:
| |
| − | sudo yum -y install httpd php
| |
| − | | |
| − | | |
| − | This configures the Apache web server to automatically start when the instance starts:
| |
| − | sudo chkconfig httpd on
| |
| − | | |
| − | | |
| − | This downloads a zip file containing the PHP web application:
| |
| − | wget https://aws-tc-largeobjects.s3-us-west-2.amazonaws.com/CUR-TF-200-ACACAD/studentdownload/phpapp.zip
| |
| − | | |
| − | sudo unzip phpapp.zip -d /var/www/html/
| |
| − | | |
| − | | |
| − | This starts the Apache web server:
| |
| − | sudo service httpd start
| |
| − | | |
| − | | |
| − | Open a new web browser tab, paste the Public IP address for your instance in the address bar and hit Enter. The web application should appear and will display information about your location (actually, the location of your Amazon EC2 instance). This information is obtained from freegeoip.app.
| |
| − | | |
| − | | |
| − | <br />
| |
| − | ====Task 4 - Create an Amazon Machine Image - AMI====
| |
| − | Now that your web application is configured on your instance, you will create an Amazon Machine Image (AMI) of it. An AMI is a copy of the disk volumes attached to an Amazon EC2 instance. When a new instance is launched from an AMI, the disk volumes will contain exactly the same data as the original instance.
| |
| − | | |
| − | This is an excellent way to clone instances to run an application on multiple instances, even across multiple Availability Zones.
| |
| − | | |
| − | In this task, you will create an AMI from your Amazon EC2 instance. You will later use this image to launch additional, fully-configured instances to provide a Highly Available solution.
| |
| − | | |
| − | | |
| − | * Return to the web browser tab showing the EC2 Management Console.
| |
| − | | |
| − | | |
| − | * Ensure that your Configuration Server is selected, and click Actions > Image > Create Image.
| |
| − | : You will see that a Root Volume is currently associated with the instance. This volume will be copied into the AMI.
| |
| − | | |
| − | | |
| − | * For Image name, type: Web application
| |
| − | | |
| − | | |
| − | * Leave other values at their default settings and click Create Image.
| |
| − | | |
| − | | |
| − | * Click Close.
| |
| − | : The AMI will be created in the background and you will use it in a later step. There is no need to wait while it is being created.
