CharmSchool Hangouts

We’re doing a series of regular CharmSchools on G+ hangouts. Last week we did an intro to juju and charming…

There’re links to the whole series of charmschool hangouts in the juju video archive where we also have videos and screencasts of demos, talks, and any other charm schools we’ve been able to capture on video.

Running the LinuxPlumbers Conference Schedule With Juju

Written by Mark Mims and Chris Johnston

Hey, so last month we ran scheduling for the Linux Plumbers Conference entirely on juju!

Here’s a little background on the experience.

Along the way, we’ll go into a little more detail about running juju in production than the particular problem at hand might warrant. It’s a basic stack of services that’s only alive for 6-months or so… but this discussion applies to bigger longer-running production infrastructures too, so it’s worth going over here.

Scaling a 2000-node Hadoop Cluster on EC2/Ubuntu With Juju

Written by Mark Mims and James Page

Lately we’ve been fleshing out our testing frameworks for Juju and Juju Charms. There’s lots of great stuff going on here, so we figured it’s time to start posting about it.

First off, the coolest thing we did during last month’s Ubuntu Developer Summit (UDS) was get the go-ahead to spend more time/effort/money scale-testing Juju.

Ensemble Renamed to Juju

Just a note that the Ubuntu Ensemble suite of DevOps tools for Ubuntu Server has been renamed to juju.

I’ll be updating previous posts to reflect the name changes so they’ll be up to date.

Stir That Memory of Autotools

Ok, never going to forget these again, dammit!

$ aclocal
$ autoconf --force
$ automake --add-missing --copy --force-missing
$ ./configure
$ OS_ARCH=amd64 make

or sometimes you can use

$ autoreconf --force --install

Node.js and MongoDB on Ubuntu

I gave my first talk on IRC the other day on deploying Node.js & Mongo in Ubuntu… it was quite a new experience. Figured I’d post details of the talk here.

An example stack

We’ll use juju to deploy a basic node.js app along with a couple of typical surrounding services.. - haproxy to catch inbound web traffic and route it to our node.js app cluster - mongodb for app storage

Along the way, we’ll see what it takes to connect and scale this particular stack of services. I’ll err on the side of too much detail over simplicity in this example, but I’ll try to make it clear when there’s a sidebar topic.
