Client.Api Version was different than Engine.Api Version Some functionalities that use docker under the hood do not work.

Suggest potential solution

In case of wasting time, maybe we can add additional logs with this information.

Have you considered any alternatives?

no

Additional context

This additional log information can resolve some issues like this https://github.com/moby/moby/issues/37959 This bug is caused by a mismatch between the client and engine version.

Thanks for the amazing software, guys; you are amazing!

It is not clear what you are asking? If you use the docker client you control the API version of that client and podman cannot do anything about that. The podman API says it supports 1.41 API version as this is what we currently support and it should support older versions as well.

[bartoszgolebiowski]

@Luap99 to add some logs to covert that case

[Luap99]

Add logs how and where? Using a older client against a newer server is normal and works fine, the server should return compatible output. If not it is a bug as long as the client is above the minimum version 1.24.

Docker does not report that a newer API is available, it only reports if the API was downgraded.

Client: Docker Engine - Community
 Version:           26.1.4
 API version:       1.41 (downgraded from 1.45)
 ...

Server: ...
 Podman Engine:
  ...
 Engine:
  Version:          5.0.0
  API version:      1.41 (minimum version 1.24)
  ...
