Hi,
I am getting this error on various versions of Jenkins and the
docker-plugin including latest of both.
My Jenkins master is running in a container. It successfully launches a
docker container for the slave (using the evarga/jenkins-slave image) but
then fails to connect with the error below.
I can see my slave running with a docker ps and can even successfully
connect to it via ssh on 0.0.0.0:32791 (or whatever the given ephmeral port
is) using the same credentials configured in the docker agent template
section.
Any ideas really welcome as I'm now going round in circles trying to get
this working.
Thanks.
