This document will help you create instances of http://daisy.ubuntu.com and http://errors.ubuntu.com deployed in the cloud.
Setting up Juju
First you'll need to create an environment for Juju to bootstrap to. Follow the directions here to get a basic environment going. I'd suggest doing something akin to the following to bootstrap the initial node:
source ~/.canonistack/novarc juju bootstrap -e canonistackone --constraints "instance-type=m1.medium"
This will ensure that the juju bootstrap node doesn't take ages to perform basic tasks because it's constantly going into swap.
You should end up with something similar to the following in your ~/.juju/environments.yaml:
environments: canonistack: type: ec2 control-bucket: juju-replace-me-with-your-bucket admin-secret: <secret> ec2-uri: https://ec2-lcy02.canonistack.canonical.com:443/services/Cloud s3-uri: http://s3-lcy02.canonistack.canonical.com:3333 default-image-id: ami-00000097 access-key: <access key> secret-key: <secret key> default-series: precise ssl-hostname-verification: false juju-origin: ppa authorized-keys-path: ~/.ssh/authorized_keys
Deploying the error tracker
Now you're ready to checkout and deploy the individual charms that make up daisy.ubuntu.com and errors.ubuntu.com, which is done by a single script:
bzr branch lp:error-tracker-deployment source ~/.canonistack/novarc error-tracker-deployment/deploy
Follow along with juju status.
Once all the nodes and relations are out of the pending state, you should be able to start throwing crashes at it.
Using the Juju error tracker
The following command sets up various SSH tunnels to the Juju instances of daisy and errors, redirects the local whoopsie daemon to report crashes against the Juju daisy instance instead of errors.ubuntu.com, and shows the local whoopsie and remote daisy-retracer logs until you press Control-C:
error-tracker-deployment/run-juju-daisy
This script has a commented out alternative of the ssh command to daisy which shows the Apache logs. Enable this, and disable the default one below if you want to debug problems with uploading the .crash files.
Generating and uploading crashes
You can generate a simple crash report with e. g.
bash -c 'kill -SEGV $$'
and elect to report the crash in the popping up Apport window.
Now open a browser to http://localhost:8081. You should have one problem in the most common problems table.
For a more systematic and regular integration test you can use an automatically generated set of .crash files for various application classes (GTK, Qt, CLI, D-BUS, Python crash) from the test crashes recipe, which currently builds the crashes for i386, amd64, and armhf for precise, quantal, and raring. You can download the current ones with
error-tracker-deployment/fetch-test-crashes
which will download them into ./test-crashes/release//architecture/*.crash. Then you can use the submit-crash script to feed them individually or as a whole into whoopsie:
error-tracker-deployment/submit-crash test-crashes # uploads all of them error-tracker-deployment/submit-crash test-crashes/raring/amd64 error-tracker-deployment/submit-crash test-crashes/precise/armhf/_usr_bin_apport-*.crash
Debugging tricks
You can purge the whole Cassandra database with
~/bzr/error-tracker-deployment/purge-db
Call it with --force to do this without confirmation.
You might want to watch out for exceptions thrown by daisy or errors themselves:
juju ssh daisy/0 watch ls /srv/local-oopses-whoopsie
If you want to use the Launchpad functionality in errors you'll need to setup Launchpad OAuth tokens and put them in /var/www/daisy/local_config.py on your errors server. Information regarding setting up OAuth tokens can be found here.
Prodstack
We're moving the production deployment of the error tracker to prodstack. Below are instructions on setting this up on Amazon EC2 and S3.
