Troubleshooting Docker containers

Event: Failed to pull Docker image :latest: Invalid repository name (), only [a-z0-9-_.] are allowed. Tail the logs for more details.

Check the syntax of the dockerrun.aws.json file using a JSON validator. Also verify the dockerfile contents against the requirements described in Docker configuration

Event: No EXPOSE directive found in Dockerfile, abort deployment

The Dockerfile or the dockerrun.aws.json file does not declare the container port. Use the EXPOSE instruction (Dockerfile) or Ports block (dockerrun.aws.json file) to expose a port for incoming traffic.

Event: Failed to download authentication credentials repository from bucket name

The dockerrun.aws.json provides an invalid EC2 key pair and/or S3 bucket for the .dockercfg file. Or, the instance profile does not have GetObject authorization for the S3 bucket. Verify that the .dockercfg file contains a valid S3 bucket and EC2 key pair. Grant permissions for the action s3:GetObject to the IAM role in the instance profile. For details, go to Managing Elastic Beanstalk instance profiles

Event: Activity execution failed, because: WARNING: Invalid auth configuration file

Your authentication file (config.json) is not formatted correctly. See Using images from a private repository
