An Entrypoint of "" causes an unwrap to panic

[TheNeikos]

I am using podman, and when running testcontainers-rs with my own image I get this panic:

thread 'echoserver' panicked at 'called `Result::unwrap()` on an `Err` value: Error("invalid type: string \"\", expected a sequence", line: 146, column: 31)', /bla/bla/testcontainers-0.14.0/src/clients/cli.rs:331:88

Looking through the source, it seems that it comes from a serde call not working.

The input that causes this has "Entrypoint": "" on the offending line, which when looking at bollard_stubs cannot be parsed. Although the comment is exactly specifying this situation, the code is wrong.

I know it is not part of your library then, but since you are depending on it, I feel like this is the first place it should be reported.

This seems to go deeper, as incompatibilities between docker/podman: fussybeaver/bollard#238

I don't think that this can truly be resolved by this project. However I do think that in this case podman should not be a 'supported' platform.

Thanks for opening the issue!

We will be removing support for podman in the near future: #422.
