A status page for the official zws.im instance of ZWS is available at status.zws.im.
Running an instance of ZWS on Heroku is the easiest way to self-host. You can also stay totally within the free limits of both the
web process and the Heroku Postgres database. Note that the Hobby Dev (free) plan of Heroku Postgres has a row limit of 10,000, which might not be enough for your use case. Consider using the API key feature of ZWS to restrict access to your instance.
We provide a template app specification YAML file to allow users to launch an instance on the DigitalOcean App Platform.
db.env and fill in the values
.env and update the
DATABASE_URL environment variable to match the values in
docker-compose up -d (this will automatically apply database migrations)
Database migrations are automatically applied on Heroku and Docker Compose. You can easily run database migrations manually through Docker Compose by running the following command:
docker-compose up migration
Make sure the
DATABASE_URL environment variable in
.env is accurate.
If you are hosting your instance on Heroku, migrations are automatically applied. If you need to manually apply migrations or are only using Heroku for your database you'll need the credentials for your database:
.env file and enter in the connection URI
Afterward you can run the migration commands shown above.
ZWS instances expose two routes that implement the Shields endpoint schema:
