kra / apps-experimenter

Setup

To be done once.

• have apps-experimenter repo with dev branch on github

• add app-dev.phu73l.net DigitalOcean domain

• virtualenv -p python3 env

• source env/bin/activate

• pip install -r requirements.txt

• pip install python-dotenv

Have:

• config.yaml based on config.yaml.sample
• .env based on .env.sample.

Set up dev instance

Create the app, note the id.

./make_app_yaml.py | doctl --config config.yaml apps create --spec -

Get the hostname from the "Default Ingress" field of the app. This may take a while before it is available.

doctl --config config.yaml apps list <id>

Add CNAME for ws.app-dev.phu73l.net pointing to the app's hostname in DigitalOcean domain. Wait for the domain status to be resolved in the settings page (or just wait longer than the TTL) and for the resulting deploy to finish.

Deploy dev instance

If source has changed, push to apps-experimenter dev branch on github.

Update config
