Podman fails pushing image to AWS ECR repository with: Error: writing blob: Post

Question

I have issues trying to push an image I created with podman to an ECR container I have.

The issue doesn't seem to be related to permissions or authentication and I am struggling to find similar issues online. I am also seeing the tagged image so the issue seems to be related to the push only.

I am getting 3 of the below errors until the 'podman push ..' commands eventually fail.

The push command was failing as the specified repository never existed.

ECR repository name: karlito96 Podman image:tag: git-pod:06

In both my tag and push commands the ECR path I chose didn't exist: ACCOUNTID.dkr.ecr.eu-central-1.amazonaws.com/karlito96/git-pod:06

It seems everything after the ..amazon.com/ and before the : is considered as the repository name. In the above example this would be: karlito96/git-pod which doesn't exist.

Resolution:

There are two ways one can choose from to work around this:

Tag your local image onto the repository with the repository name, with the earlier used ECR repo and image this would look like:

 $ podman tag git-pod:06 ACCOUNTID.dkr.ecr.eu-central-1.amazonaws.com/karlito96:latest
 $ podman push ACCOUNTID.dkr.ecr.eu-central-1.amazonaws.com/karlito96:latest

Create a repository with the name of your image, and then push to that directly:

 $ podman tag git-pod:06 ACCOUNTID.dkr.ecr.eu-central-1.amazonaws.com/git-pod:06
 $ podman push ACCOUNTID.dkr.ecr.eu-central-1.amazonaws.com/git-pod:06

Podman fails pushing image to AWS ECR repository with: Error: writing blob: Post
