Some test/dev enviroments may use alternate docker daemon implmentations.
The Docker utility crate bollard
uses the default endpoint of unit///var/run/docker.sock
or the DOCKER_HOME
environment variable, not the docker context
default.
docker context ls
can be use to discover the value to set DOCKER_HOME
environment variable so that that the integration_test target
will use to correct
docker connection.
