codebuild-custom-docker-image

Building custom docker image with tools for codebuild projects.

As pulling the docker images from dockerhub got throttled, so there is a high chance whenever we want to build something , we might get into this trouble. So CFN templates takes care of that. It creates following things for building the automation:

1. ECR(EC2 Container Registry)
2. A CodeBuild Project with buildpec inside for installing various tools like below which can be adjusted via the Makefile

• Terraform
• Tfenv
• Boto3
• Configures Python3
• Golang
• Jq
• Unzip

3. A CloudWatch Crontab entry to invoke the CodeBuild Job at midnight
4. A CloudWatch event Rule catches the CodeBuild status for following states:

• FAILED
• STOPPED
• SUCCEEDED

5. Event Rule subscribed to a SNS Topic
6. And then AWS Chatbot receives notifications from above SNS topic eventually send them to Configured Slack Channel.

The idea can be further refined to have a custom lambda deployed and subscribed to cloudwatch events for codebuild status updates, process the status maybe add more metadata to it and send the notification via slack or SES.

Note:

• As of now AWS Chabot is not supported via terraform[1] because there is no support via AWS Go SDK[2]. So this might look more cleaner in terraform.
• There might be in future AWS will deliver Public Container Registry[3], till then this helps us to keep things running.
