Demo Deployment Notes

Notes re: deployment of demo version of app on skookum for 19-Jul-2021 MIDOSS Stakeholders Workshop. Some steps require sudo access, and messing around with pre-creation of directories via mkdir and adjustment of ownership from root:root to dlatorne:sallen.

  1. Clone repo from GitHub into /SalishSeaCast/

  2. Create symlink in app code directory to Ben's tiles assets directory tree:

    $ ln -s /ocean/bmoorema/research/MEOPAR/data/midoss-app/tiles /SalishSeaCast/midoss-app-dev/midoss_app/tiles

  3. Create conda env:

    $ cd /SalishSeaCast/midoss-app-dev/
$ conda env create --prefix /SalishSeaCast/midoss-app-env -f envs/environment-deploy.yaml

  4. Activate conda env and do editable install of app in env:

    $ conda activate /SalishSeaCast/midoss-app-env
(midoss-app-env)$ python3 -m pip install -e /SalishSeaCast/midoss-app-dev

  5. Add reverse proxy directives to /etc/apache2/sites-enabled/000-default.conf:

    # salishsea.eos.ubc.ca/midoss - MIDOSS Monte Carlo fields viz demo app                                                                                                                                                                                                                                                       
ProxyPass /midoss http://salishsea.eos.ubc.ca:5050/midoss
ProxyPassReverse /midoss http://salishsea.eos.ubc.ca:5050/midoss

  6. Create directory to hold log files:

    $ mkdir /SalishSeaCast/logs/midoss-app/

  7. Start a tmux session to run the app in:

    $ tmux new -s midoss-app

    Activate the environment in the tmux session, and launch the app using the production configuration:

    $ conda activate /SalishSeaCast/midoss-app-env
(midoss-app-env)$ cd /SalishSeaCast/midoss-app-dev/
(midoss-app-env)$ pserve production.ini

    To re-attach to the tmux session, use:

    $ tmux attach -t midoss-app
