While trying to run a docker.push on a ppc64le Jenkins slave called by an x86 Jenkins master, the following error occurs.
Remote call to JNLP4-connect connection from /
java.lang.UnsatisfiedLinkError: /tmp/libnetty-transport-native-epoll3535546627560640699.so: /tmp/libnetty-transport-native-epoll3535546627560640699.so: cannot open shared object file: No such file or directory (Possible cause: can’t load AMD 64-bit .so on a Power PC 64-bit platform

sh """
docker build . -t ${imageTag}
docker push ${imageTag}
"""
