• Contents– Opensuse base w/ required libraries (runtime)– CoprHD rpm

• How to build– Run “make BUILD_TYPE=oss docker”

• Outcome– A docker image: “coprhd-devkit”

BUILDING THE IMAGE

• Same image, multiple deployment types

• Problems to solve– Static IP– Accessing the internal IPs from outside (NAT)

DEPLOYING THE IMAGE

• CoprHD needs it, but docker doesn’t

• Docker provides a way and a future plan (libnetwork)

• For now we use pipework
