Action Build

Action Build is docker image build scripts using github actions and bitbucket pipeline and pushing them in AWS ECR.

Before we start, We need to create a repository on AWS ECR.

github actions

Building with github actions requires us to create a .github/workflows/ directory in the root of our project. We will call our file ecr.yml.

Then,

git clone git@github.com:thearyanahmed/action-build.git

cd action-build

or you can simply copy the ecr.yml file and paste it in your project's workflows directory.

The script looks for a Dockerfile on the root of your project, if its not present there, make sure the change it on line 33 of .github/workflows/ecr.yml file.

Also, we will only be building and pushing images when a push has been made into the build-ecr branch. You can change it from .github/workflows/ecr.yml's line 6.

Build secrets

as we will need to login to aws from the action, we need a few secrets.

• AWS_ECR_REPO will be the repo name from url/repo . eg: If the repo is $accountID.dkr.ecr.us-east-1.amazonaws.com/hello-world, AWS_ECR_REPO will be hello-world.
• AWS_ACCESS_KEY_ID your aws access key.
• AWS_SECRET_ACCESS_KEY your aws secret key.
• AWS_DEFAULT_REGION the default region of your project, eg: us-east-1

You'll need to set the in your repository's secrets. So thats Settings > Secrets > New Repository Secret.

After setting these, git checkout to build-ecr branch or the branch you chose for the deployment.

Now, for the tag versioning, the very last commit message will be used. For example, if I want to tag my image 1.38, the very last commit message should be 1.38.

To finally build and push to ECR,

git commit -m "1.38"; git push origin build-ecr

bitbucket pipeline

Same as above, we will be pushing on build-ecr branch, but you can change that from line 8 of bitbucket-pipeline.yml.

Build secrets

• AWS_DEFAULT_REGION the default region of your project, eg: us-east-1
• AWS_REGISTRY_URL will be the long url/repo name. eg: $accountID.dkr.ecr.us-east-1.amazonaws.com/hello-world
• AWS_ACCESS_KEY_ID your aws access key.
• AWS_SECRET_ACCESS_KEY your aws secret key.

Now, for the tag versioning, the commit message will be used. For example, if I want to tag my image 1.38, the commit message should be 1.38.

The script looks for a Dockerfile on the root of your project, if its not present there, make sure the change it on line 16 of bitbucket-pipeline.yml file.

To finally build and push to ECR,

git commit -m "1.38"; git push origin build-ecr

A demo docker file has been added to test.
