Description

I'm using the plugin to build Docker images on x86_64, ppc64le & s390x architectures. Plugin is working fine on x86_64, ppc64le but is failing as following on s390x:

[ERROR] Failed to execute goal io.fabric8:docker-maven-plugin:0.29.0:build (build) on project ci.docker: Execution build of goal io.fabric8:docker-maven-plugin:0.29.0:build failed: An API incompatibility was encountered while executing io.fabric8:docker-maven-plugin:0.29.0:build: java.lang.UnsatisfiedLinkError: could not load FFI provider jnr.ffi.provider.jffi.Provider

Thanks a lot, any help would be appreciated. (also tried the skip.docker.machine option without success)

The problem is, that it looks like that https://github.com/jnr/jnr-unixsocket doesn't support this architecture. d-m-p uses jnr-unixsocket for communication with the Docker daemon vail local Unix sockets. The alternative is, to use TCP for talking to the Docker daemon which I would recommend in this case.

We can only support Unix socket via jnr-unixsocket only, so I suggest to open a feature request over there to support System Z. I'm afraid, that's all we can do.

This issues looks similar: jruby/jruby#1389

Hi,
Ok thanks. I'm then using another way to build these images.

Hi,
I had a response from jnr-unixsocket for s390x support, see jnr/jnr-unixsocket#71
Could you please have a look and let me know if you can now support this architecture ?
Thanks

[rhuss]

Sorry, but as long as there is no official support from jnr-unixsocket or at least included in theri distribution, there is nothing we can do from our side. d-m-p will only support released version of jnr-unixsocket.

I've seen that there has been a new release of jnr-unixsocket, so you might want to try update the dependency version in pom.xml and then build d-m-p locally to try this out.

The same issue occurs on Apple M1 machines.

@saschpe thanks for bringing this up. I'd propose to monitor jnr/jnr-unixsocket#95 and soon as this is fixed and released, we can update the dependencies.
