# Gen image via s2i ... using python container
IMGBASE=s2i-python-container
mkdir s2iloadgen
s2i create ${IMGBASE} s2iloadgen

• List all Bluejay-related images:

  docker images | grep -i bluejay

• Start container:

  docker run -d -P --name loadgen001 bluejay-loadgen

• Show port mapping:

  docker port loadgen001 22

• Stop container:

  docker container stop loadgen001

• Remove container:

  docker container rm loadgen001

• Remove image:

  docker image rm bluejay-loadgen

In order for containers to be able to resolve external names, change the dnsIP value in /var/lib/origin/openshift.local.config/node-localhost/node-config.yaml to the real LAN's DNS nameserver
