About this blueprint

Docker AWS

This flow will build a Docker image and push it to a remote container registry.

  1. The dockerfile parameter is a multiline string that contains the Dockerfile content. However, it can also be a path to a file.
  2. The tags parameter is a list of tags of the image to build. Make sure to set a correct AWS region, and adjust the rest of the image URL to match your ECR repository.
  3. The push parameter is a boolean that indicates whether to push the image to the Elastic Container Registry.
  4. Make sure to securely store your AWS credentials as secrets or environment variables.
  5. Finally, note how we used the GetAuthToken task to fetch an access token for the docker command. This is necessary to authenticate the task with your ECR registry.
