[AWS] Lab: Docker and CodeCommit Part 1

Overview

Create IAM User with CodeCommit Access

Configure local AWS user

aws configure

HTTPS Git credentials for AWS CodeCommit

Create CodeCommit Repo

• Clone the Repo by using HTTPS
• Copy Dockerfile and buildspec.yml to your local repo

Dockerfile

FROM ubuntu:12.04
# Install dependencies
RUN apt-get update -y
RUN apt-get install -y apache2

# Install apache and write hello world message
RUN echo "Helloo Cloud Gurus!!!! This web page is running in a Docker container!" > /var/www/index.html

• Push files to remote CodeCommit repo

Next, we are going to create a Elastic Container Service to able to run our Docker image.

Create ECS

Once it successed, you should be able to see your cluster:

Create Repositories

• Give a name for your repo, for example: `mydockerrepo`
• Click button "View Push Commands"

When you run the first command, you will get Auth Error, what you need to is add permission to your created user

Add Permisson for User

• Run the "View Push Commands" again, you will see "Login Successed"
• Build Docker image
• Tag Docker image
• Push Docker image

• Click "Copy URI" in last image, we need to use it later

Launch Docker Container

• Go to Task Definitions
• 
• Give a name `mytaskdef`
• 
• Click "Add Container"
• 
• "image" is the URI that we just copy

• Create a Service

• Launch Type should be "EC2"
• Service name: "myservice"
• Number of tasks: 1
• Rest should be default

You should see service has reached a stead state

• Go back to "Cluster" -> "myCluster" -> "EC2 instance" -> Copy "IPV4 public address" -> Open in Broswer
•
