Pegasus supports deploying to Render as a standard Python application.
If you haven’t already, create your Render account.
To use celery you will need to upgrade to a paid plan.
Once you’ve logged into Render you can create your app as follows:
In the Render dashboard, create a new blueprint
Connect your GitHub or Gitlab account and select your project’s repository
Configure the Service Group Name and select the branch you want to deploy from
Review the configuration, add settings and click ‘Apply’
This will kick off the process to create your PostgreSQL database and Redis instances as well
as deploy your web application (configured in your project’s
After deploying, review the production checklist for a list of common next steps
build.sh file is run by Render to run the commands needed to build the app,
as described here.
This is also where “release” commands like
If there are other commands (e.g.
that you want to run on every deploy you can add them to
If you enable celery, it will use the
build_celery.sh file, which runs the basic build steps,
but not the “release” commands.
You generally should not need to modify this file.
Settings and Secrets#
Render builds use the
You can add settings here or in the base
settings.py file, and use environment variables to manage any secrets,
following the examples in these files.
Environment variables can be managed from the “Environment” tab on your app’s dashboard.
Running One-Off Commands#
You can run one-off commands in the Render shell (paid plan required) or via SSH.
To run celery workers on Render you will need to upgrade to a paid plan.
Then in your
render.yaml file uncomment the ‘celery’ section and rebuild from the steps above.
If you previously deployed your application you can choose “Update Existing Resources” to avoid having to recreate your app / database / redis instance.
Sometimes Render fails to build on the first deployment. Retrying the deployment from the same commit seems to resolve this.
It is possible to use Render’s docker-based support to deploy Pegasus apps, but it is not recommended because there is no “release” phase, which makes it difficult to set up things like database migraitons.
