I'd say there are two approaches: you can use the container-native
approach ("docker run" after provisioning some container-enabled host
using Nova or K8s cluster using Magnum), or you can use the
OpenStack-native approach (zun create nginx) and have it
auto-provisioned for you. Those projects have a narrower scope, and
fully co-opt the container ecosystem without making us appear as trying
to build our own competitive application packaging/delivery/marketplace
mechanism.
I just think that adding the Murano abstraction in the middle of it and
using an AppCatalog-provided Murano-powered generic Docker container
wrapper is introducing unnecessary options and complexity -- options
that are strategically hurting us when we talk to those adjacent
communities...
