I am trying out AWS ECR and pushing a new tag to our private repossitory.
it goes like this:
export DOCKER_REGISTRY=0123123123123.dkr.ecr.us-east-1.amazonaws.com
export TAG=0.1
docker build -t vendor/app-name .
`aws ecr get-login --region us-east-1`" # generates docker login
docker tag vendor/app-name $DOCKER_REGISTRY/vendor/app-name:$TAG
docker push $DOCKER_REGISTRY/vendor/app-name:$TAG
Login works, the tag is created and I see it with docker images, but the push fails cryptically.
The push refers to a repository [0123123123123.dkr.ecr.us-east-1.amazonaws.com/vendor/app-name] (len: 2)
b1a1d76b9e52: Pushing [==================================================>] 32 B/32 B
Error parsing HTTP response: unexpected end of JSON input: ""
It very well might be a misconfiguration, but I can't figure out how to get more output out of it. The command has no debug level options, there are no other logs and I can't intercept network traffic since it seems encrypted.
Ran into the same issue. For me, ensuring that the IAM user I was pushing as had the ecr:BatchCheckLayerAvailability permission cleared this up.
I had originally intended to have a "push-only" policy and didn't realize this permission was required to push successfully.
