Wikimedia Apps/Team/RESTBase services for apps/Deployment process/Setup notes

Setup
Here are the detailed notes to get ready to update the deployment repo for our mobileapps RESTBase service on a Ubuntu box setup (inside a VirtualBox VM).

Personal Gerrit / Git setup
Setup SSH key for Gerrit: Go to the Gerrit Web UI Settings: Click on Add Key and follow directions there.

You may also need to set your email and name in git if you haven't done so. (I'm mentioning it here since I ran into this myself because I was running that in a fresh Ubuntu install inside VirtualBox.) Adjust the values, of course:

Set up source and deploy repos
Note that you have to set an environment variable here for the setup only (for temporarily, no need to stick that into an rc script):

Docker
The easiest way to install Docker: Then, you need to add your user to the  group, follow the note at the end of the docker commands to do that. In other words: After all of that, reboot your VM. Then, you can run the tests inside Docker:

Nagios Setup
Checking the service with Nagios before building the deploy repo can help to identify problems and prevent deployment reverts.

(Note: These instructions are only the minimum required for command line usage, adapted from the Nagios Ubuntu Quickstart guide.)

Install prereqs:

Create a Nagios user:

Download, build, and install Nagios:

Download, build, and install nagios-plugin:

Start Nagios:

Download the WMF service checker plugin:

Now, to run the endpoint checks, start the service, then do:

Once that is all working you can prepare the deploy repo as part of the deployment process.

Git tag setup
Git tags are cryptographically signed and a GPG signing key is therefore required.

(or get GPG if you need it)

If no keys are listed or you just installed GPG, create a new signing key with:

Then configure the new key (or desired existing key) as the signing key for the mobileapps repo:

(add the   flag if you want to use this signing key for all repos)
