ECR

• First step is to create a repository
  • aws ecr create-repository --repository-name <repository-name> --image-scanning-configuration scanOnPush=true --region <region>
  • We can include slashes in repo name for eg: company-name/<something>
• Once you create a repo you can push images in it using the repository URI
  • <account-id>.dkr.ecr.<region>.amazonaws.com/<repo-name>
• Describing the repositories to see all the repositories
  • aws ecr describe-repositories -region <region>

• Building docker images

  • docker build -t image-name .: assuming Dockerfile is in the same directory.

• To push the docker image to ECR we need to login

  • If you login successfully you should see Login Succeeded message
• We need to tag the docker images with the same name as the repository with version
  • docker tag <image-name> <account-id>.dkr.ecr.<region>.amazonaws.com/<repo-name>:1
  • We do this in order to tell docker that we want this image to be pushed to ECR
  • Tag basically means that we are renaming the image.
  • Here 1 is the version number we can also have latest or any other version

In ECR you create a repository per image.

• For each image you have its own repository.
• We store different tags/versions of the same image in our repository.

• Image naming in ECR:
  • registryDomain/imageName:tag
• We can do docker pull nginx:latest since it is equivalent to docker pull docker.io/library/nginx:latest
  • But we can't skip this in private repositories.
