In this 6-part series on configuring a CI/CD pipeline using Customized Docker image on an Apache Web Server, Application Load Balancer, ECS, ECR, CodeCommit, CodeBuild, CodeDeply services -

In the 4th article, We will create a CodeCommit Repository, and with proper permissions to IAM User, Using SSH public keys we will authenticate access to AWS CodeCommit, then Clone the repository and we will move the Dockerfile and index.html inside the repo and push them to remote repository master branch.

Let’s get started!

Please visit my GitHub Repository for Docker/ECS/ECR articles on various topics being updated on constant basis.

Objectives:

1. Create a CodeCommit repository called "my-codecommit-repo"

2. Assign permissions to IAM User to access CodeCommit

3. Use SSH public keys to authenticate access to AWS CodeCommit

4. Clone the repository

5. Move the Dockerfile and index.html inside the repo and push them to remote repository master branch

Pre-requisites:

• AWS user account with admin access, not a root account.
• AWS CLI.

Resources Used:

CodeCommit

AWS CodePipeline

Steps for implementation to this project

1. Create a CodeCommit repository called "my-codecommit-repo"

• On the Codecommit dashboard, Repositories, Create repository, my-codecommit-repo, Description - my-codecommit-repo, Tags, Name, Value - my-codecommit-repo

• Create

• On the connection steps page

• There are 3 types of connections, HTTPS, SSH and HTTPS (GRC)

• I am going to be working with SSH connection

2. Assign permissions to IAM User to access CodeCommit

• On IAM Dashboard, Users, goti2, Permissions tab, Add permissions, Attach policies directly, Search and select AWSCodeCommitPowerUser, Next, Review and Add permissions

3. Use SSH public keys to authenticate access to AWS CodeCommit

• SSH into the EC2 Instance thru Putty

• Go to the docker folder using the command
  

sudo su
cd /opt/docker

• Install git

yum install git -y

• Generate the public and private keys for Git and CodeCommit

ssh-keygen

• Go to the SSH keys location

cd ~/.ssh/

• command "ll" to check.

• In order to access the CodeCommit through SSH, we need to copy and paste the SSH public key in IAM User

• Use the following command to copy the public key content
  

cat id_rsa.pub

• On the IAM console, Users, click on the user - goti2, Go to the Security credentials tab and under SSH Keys for AWS CodeCommit, Click on Upload SSH public key

Make sure to paste it properly to avoid errors in the future

• Once pasted, click on Upload SSH public key, you can see the SSH Key ID

• Copy the SSH Key ID for future reference.

• Back to the CodeCommit, SSH connection page, Linux, Step 3, Copy the 3 lines of code in step 3

Step 3: Edit Local SSH Configuration

Edit your SSH configuration file named "config" in your local ~/.ssh directory. Add the following lines to the file, where the value for User is the SSH Key ID you copied in Step 2.

Host git-codecommit.*.amazonaws.com
User Your-IAM-SSH-Key-ID-Here
IdentityFile ~/.ssh/Your-Private-Key-File-Name-Here

Once you have saved the file, make sure it has the right permissions by running the following command in the ~/.ssh directory.

chmod 600 config

• In the .ssh directory, Create a file - name it config

Host git-codecommit.*.amazonaws.com
User APKAT7SS6ZVXC6LRIFXL
IdentityFile ~/.ssh/id_rsa

• To change the permissions for the config file

chmod 600 config

• Go to the docker folder

cd /opt/docker

4. Clone the repository

• Clone command from the SSH page in CodeCommit

Clone your repository to your local computer and start working on code. Run the following command

git clone ssh://git-codecommit.us-east-1.amazonaws.com/v1/repos/my-codecommit-repo

5. Move the Dockerfile and index.html inside the repo and push them to remote repository master branch

• Go to the docker folder

sudo su
cd /opt/docker

• Move the dockerfile and index.html file to my-codecommit-repo

mv dockerfile index.html my-codecommit-repo/

cd my-codecommit-repo

ls -lt

• to add all the files to the git

git add .

• Check the status

git status

• Commit the files

• Pushing the files into the remote repository’s master branch

git push

• to the CodeCommit repository and check the files.

What we have done so far

• We have successfully created a CodeCommit Repository, authenticated using SSH public keys, cloned the repository, and moved the Dockerfile and index.html inside the repo and pushed them to remote repository master branch.
