Open Stack

Hrm, well, this is a discussion I was hoping to have in Vancouver, but we
never got around to it.

I feel we actually want three projects. One, which permits a standalone
Ironic Dashboard. One, which integrates Ironic with Horizon. One, which
contains as much common code as possible. And, potentially, one that
contains as much common code between, say, an ironic shared library and a
glance shared library. Because Ironic isn't the only project out there that
may.... and I know this is CRAZY... but there are other projects that MAY
not want to be dependent on other projects.

So while I do not have a problem with an ironic dashboard inside horizon's
angular dashboard, and I do not have a problem working on that, I'm rather
concerned about the feasibility of that right now. And the reason's really,
really simple: The plumbing's not there yet.

What I mean by that is that the dependency mechanism by which all these
projects could chain off of each other isn't there. And the mechanism by
which these projects are published from infra isn't there. And we haven't
quite agreed on even common style rules yet. And a long list of other
necessary things that come from having to catch up with
K-#-of-releases-in-years of Infra having a full team of engineers working
on building up a testing infrastructure.

And, while I understand that "Hey why don't we just start one project and
split it apart when need arises" is a valid approach, or "What's wrong with
horizon" is a likely question, I personally feel that they're all hacks,
and as engineers of enterprise software we have to be more meticulous than
that.

But: Do I want to stand in the way of an ironic-dashboard because all of
these plumbing requirements? No. But please understand that until that
plumbing is in place, and until we reach consensus on how we do javascript
in openstack, any decisions you make on technology choice, architecture,
project structure, and implementation is about 75% likely to have to be
redone, and I will very happily -1 every patch of yours and tell you so.

And I'm working on that plumbing. So if you want to help, here's my current
list of TODO Items that I have to complete before I become a new dad in
early september.

- Land CORS support in our API's.
- Fix all the linting errors in Horizon. This will permit horizon to gate
on javascript style guidelines, and finally use the javascript-jobs
template in the gate.
- This will permit merlin to adopt the javascript style guidelines, and run
them in the gate.
- This will also permit angular-ironic-dashboard-rainbows-and-unicorns to
adopt those guidelines, and run them in the gate.
- We need to figure out how to gate a javascript API library integration
test against devstack. And then we need to standardize that build across
all projects that use the javascript builds.
- We need to figure out how we make sure library dependencies are shared
between projects, so our versions don't get out of sync (i.e. I can import
things from the ironic shared lib into both horizon and ironic-webclient).
- We need to talk to the infra team about publishing released javascript
library tarballs to an authoritative, stable "Repository". The reason for
this is that Infra doesn't like skynet, and therefore doesn't let zuul or
any of our other tools push code back to our git repositories in an
automated fashion. So the javascript-world's use of
Git-As-The-Authoritative-Source-Of-Everything is unlikely to work for us,
so we have to publish tarballs (alternative solutions to this are
appreciated).
- We need to teach both bower and npm to consume our tarballs. This isn't
strictly a need, as we can just express our dependencies as absolute URI's
_to_ those tarballs, but if the world at large is interested in starting to
build their own Apps On OpenStack using the javascript API's, that's
something we want to do.
- We need to have a serious discussion about ACL's in gerrit, as well as
what it means to be a core on Horizon, vs a core on an oslo-like library
that is consumed by horizon and other projects.
