Rancher desktop - port 2375?

In an attempt to find a viable alternative to docker desktop, …

  • I’ve installed rancher desktop on my windows workstation (after deleting docker desktop and aliasing nerdctl to docker)

  • basic nerdctl commands work

  • However, when attempting to build java source code using the maven fabric8 plugin, … I encounter the following error. I’d like to know what I need to expose in rancher (equivalent to docker)

[ERROR] Failed to execute goal io.fabric8:docker-maven-plugin:0.33.0:build (docker-image-build-verify) on project xxxxx-container: Cannot create docker access object : Connect to 127.0.0.1:2375 [/127.0.0.1] failed: Connection refused: connect -> [Help 1]
[ERROR]

Some background on port 2375

I could be wrong but, I think, the maven plugin talks to a docker socket. Rancher Desktop does not provide a docker socket at the moment. This would cause issues like the ones you’re seeing.

You should be able to have Docker Desktop and Rancher Desktop side by side on a system. Better Docker compatibility is planned for the upcoming 0.7 release.
