Hi there,

I'm currently working on docker support in 389-ds.

The current status is "almost there", but before I approve it for use I
have a high standard I want to meet. I want our support to be the best
possible.

I want to be able to redefine root password via envariables, and I want
to be able to configure the server via environment or some other means
that would work nicely in something like kubernetes so you can then
have scripted scaling for replicas.

We also have some plans for inplace upgrades (rather than the perl
scripts) so that containers can upgrade at run time rather than relying
on rpm/deb to run upgrade scripts.

Today, you can run ds in a container, but you need to build the
/etc/dirsrv/slapd-<instance> directory "seperately" and then bring that
to the container.

If you are interested in testing the current image, I can provide steps
on using it, and if you have some use cases or ideas, I'd love to hear
them. I really want our docker support ready in the next few months.

Thanks!
