With good reason the team is unlikely to be comfortable answering your
question, but I am happy to do so.

Juju is essential to  our success with large customers every day. It
makes it possible for us to support complex OpenStack and Kubernetes
deployments that are regularly extended and upgraded and updated,
something that nobody else can in practice deliver. And those customers
are increasingly wanting to use it for a broader array of software. So
Juju has its place in our plan and I am very happy with the way the team
is now organised, with team leads who really care about quality,
performance, features and customers. I hope you've noticed a big step up
in the quality and focus of Juju releases since 2.x and I would credit
the teams and their leads with that.

I asked every single team at Canonical, with a few specific exceptions
for example LXD and the security team, to participate in the cut, on the
basis that I wanted every manager to have to exercise this kind of
judgment. It's tough, but it's also important for a company to be
confident that it is constantly improving and assessing itself.

In the case of Juju Core and JAAS, I had already driven some changes in
this regard, and I felt the team was already substantially more focused
and doing well, so there was a gentler approach, although it is always
an emotional and difficult process even if it touches relatively few
colleagues. We will miss those colleagues but I think you can count on
steady and exciting progress in Juju and JAAS.

In the teams who work on charms, we are concentrating more folks around
the key pillars of OpenStack and Kubernetes, which are manifestations of
the "os-at-scale" so we (Canonical) are the natural vendor. We are also
asking the folks who lead charm-tech to use the K8s charms as their
proving ground, to ensure those tools really work for complex charm
development. We will also continue to anchor the Hadoop ecosystem but I
am delighted with the growth in third-party interest in charms in that
ecosystem and I am happily counting on you, Merlijn, and the other
members of the Hadoop charm ecosystem, to drive forward the broader
suite of charms there and elsewhere at the application level.

Thank you for the pointer. I'll take a look. Can it package local charms?

Re: Can we do bundle within a bundle?

2017-04-20 Thread fengxia 
If we have a tree hierarchy, three levels, 1,2,3 where lvl 1 is the 
root. We are thinking to make entity at each level a charm. I can see at 
level 2 I can create bundles to include level 3 charms, how about level 
1 then? What artifact should I use to include bundles in lvl2?

[Review Queue]: elasticsearch (v5!) and general cleanup

2017-04-20 Thread Kevin Monroe 
Hey Juju, I spent some time in the review queue today:


   -

   Cleanup
   -

  Moved reviews that were awaiting author feedback into “Needs Fixing”
  -

   Elasticsearch
   -

  https://review.jujucharms.com/reviews/103?revision=270
  -

  Minor README suggestions
  -

 http://paste.ubuntu.com/24420775/
 -

  Created new lp team to house this and other ELKy things:
  -

 https://launchpad.net/~elastic-ops
 -

  Recommended moving this charm to the above team.
  -

  Though this deployed and ES5 looks fine, I’m giving this a -1 for now
  while we work out the details for a new home.


Questions/comments?  Fire away in #juju on Freenode.

Thanks!

A+ HTTPS with the SSL termination proxy

2017-04-20 Thread Merlijn Sebrechts 
Hi all


Want to have A+ HTTPS for your juju-managed webservice? Want to secure a
webservice with a password? The SSL termination proxy charm
 to your rescue!

It's a reverse proxy that encrypts traffic using a Let's Encrypt
certificate with optional Basic Authentication. Deploy the charm, set fqdn,
connect to your webservice, and go! The deployed proxy gets an A+ ssl
rating on the Qualis SSL Server Test.

It's not ready yet to be promulgated but it should work fine for demo
deployment so give it a test drive if you're interested.

If anyone wants to work together on this charm to expand its scope, let me
know! I'm thinking about stuff like pluggable authentication backends,
pluggable DNS backends, support for more protocols such as websockets, ...



*PS: The charm currently doesn't work on JaaS due to a bug with charms with
terms , but that should
change soon as the bug has high priority.*


Kind regards
Merlijn

A tutorial introduction to juju charm dev

2017-04-20 Thread Erik Lönroth 
Hello!

Let me introduce myself to the email list. My name is Erik Lönroth and I
work as technical lead on high performance computing at Scania. Scania it a
truck manufacturer in europe and part of the Volkswagen group.

I'm a strong advocator of the open source culture and my background is in
software development, system linux administration. Juju makes alot of sense
to me so, thanx for bringing this software to the community!

After some reading, experimenting and failing - I found it a bit daunting
to get started with developing juju charms. It took me some time to get
through even if the documentation is not that bad. I haven't found many
good intro-level tutorials that gets me quickly up to speed on developing.
I'd love to help change that.

My coworkers at Scania need this kind of education too, so I have tried to
create a tutorial to get a very simple "hello world" example up and
running. I'd like to share it with you and hopefully with your feedback add
more advanced tutorials later. Hopefully anyone like me, new to charm
development, finds it useful.

Here is my "hello-world" charm tutorial.

Pretty much, but it really depends on your charm.

The changes you hear about don't change the direction of Juju. We're still
focused on building a great platform for modeling and solving the software

Thanks for the <3, the teams appreciate it when folks find value in their
