How to set up your loaner to duplicate a one-click loaner
Raw
instructions.md

First, start a one-click loaner and in the shell, select item 2. Then, make a note of the command that runs (you'll need it for a step below). The first time I did this, I did mochitests, and the command line looked like /home/worker/workspace/mozharness/scripts/desktop_unittest.py --config-file /home/worker/workspace/mozharness/configs/unittests/linux_unittest.py --config-file /home/worker/workspace/mozharness/configs/remove_executables.py --no-read-buildbot-config --installer-url=https://queue.taskcluster.net/v1/task/<taskid>/artifacts/public/build/target.tar.bz2 --test-packages-url=https://queue.taskcluster.net/v1/task/<taskid>/artifacts/public/build/target.test_packages.json --mochitest-suite=plain-chunked --e10s --total-chunk=10 --this-chunk=2 --download-symbols=true --no-run-tests

For anything else to work, as root you first need to apt-get install python-virtualenv

Then, login as the regular user (cltbld is the default name)

  1. Make a directory for your work: mkdir $HOME/workspace (you can choose whatever directory you want here, but make sure to change as appropriate in later steps, as well)
  2. cd $HOME/workspace
  3. Download the mozharness from your try run: curl -L -o https://queue.taskcluster.net/v1/task/<taskid>/runs/0/artifacts/public/build/mozharness.zip (replace with the appropriate taskid from the command you copied from your one-click loaner)
  4. unzip mozharness.zip && rm mozharness.zip
  5. Remember that command you copied from your one-click loaner way up at the top of this gist? Run that, make sure you replace all instances of /home/worker/workspace with whatever path you created in step 1 above.
  6. mkdir $HOME/bin
  7. ln -s $HOME/workspace/build/tests/mach $HOME/bin
  8. export PATH=$PATH:$HOME/bin
  9. ln $HOME/workspace/build/venv/bin/python $HOME/workspace/build/venv/bin/python2.7
  10. source $HOME/workspace/build/venv/bin/activate
  11. Use mach to run your tests! (In the case of my mochitests, it was mach mochitest --total-chunks=10 --this-chunk=2)

A couple notes - you don't strictly need to go through steps 6 through 8 above, they just make it easier to run mach by putting it in your PATH. You can always type out the full path if you want.
