he error message you're seeing, specifically the "no such host" part, indicates that the DNS resolution for the ECR endpoint is failing. This could happen for a variety of reasons, but here are some common troubleshooting steps you can follow:
- Verify the ECR URL: Ensure that the URL for the ECR repository is correct. Double-check the account ID and region to make sure they are accurate.
- Docker Daemon Restart: Sometimes restarting the Docker daemon can solve transient issues. You can do this with the following command:
sudo systemctl restart docker
-
AWS CLI Version: Ensure that you are using the latest version of the AWS CLI and Docker. Outdated versions might have compatibility issues.
-
Proxy Settings: If you are using a proxy, ensure that it's correctly configured to allow connections to the ECR endpoints.
-
Explicitly Specify the Protocol: You may try specifying the protocol (https) in the ECR URL. Like this:
docker push https://{acct id}.dkr.ecr.{region}.amazonaws.com/playwright:latest
-
Retry the Operation: Transient network errors can sometimes cause this issue. Simply retrying the push operation might resolve it.
-
Check System Logs: Sometimes, system logs can provide more detailed information about the underlying issue. You can check the Docker logs or system logs for more details.
The ECR Url is correct. I'm using the push commands shown in the repo. How come some layers succeed and others dont?
