0.4.1: object has no attribute 'rsplit'

Upgraded. When I reached code to pull my repositories, I get the following:

AttributeError: '_NotSet' object has no attribute 'rsplit'

Probably won't dig into the issue tonight, but wanted to at least get it reported.

That was the API. Here's the CLI error at the same place:

If you use code similar to what you described when reporting the client parsing errors, there has been a change in the containers property in Docker-Map from 0.7.0 to 0.7.1. It was intended to be working similar to several other objects (e.g. the volumes property) as

• access to items is possible via both dictionary and attribute syntax (e.g. containers['c1'] is equivalent to containers.c1);
• iteration goes by items, not keys as usual for dictionaries.

Unfortunately the behavior was not as documented which went unnoticed for a while. So the code from your earlier example could be changed similar to this:

for container_name, container_config in env.docker_maps.containers:
    docker_client.pull(container_config.image)

Whereas the attribute access is just an additional feature that should not cause any issues, the iteration behavior change probably should have been mentioned in the change log.

Thanks for the explanation.
