#docker - April 2020

Can someone explain the reasoning why all the buildspec.yml examples I see for AWS CodeBuild/CodePipeline have you push up 2 docker images to ECR?

like this:
post_build:
commands:
- echo Build completed on date
- echo Pushing the Docker images...
#
- docker push $REPOSITORY_URI:latest
- docker push $REPOSITORY_URI:$IMAGE_TAG

I'm probably missing something basic here...

Its the same image, just tagged twice

once with the evil latest tag, another with your image_tag

is there a better way to do it? All the examples I've seen use latest, but i'm open to a better way?

Does anyone have experience with using instance storage vice EBS for EC2 instances in ECS? If so, was there any noticeable performance gain?
