How to deploy

TL;DR:

  1. Create Dokku app, link Postgres
  2. Clone this Template
  3. Set CI/CD envs in Github repo settings
  4. Push something to trigger deploy
  5. Enable Https if required

Create Dokku app

On your server (where Dokku is installed):

dokku apps:create prefect
dokku config:set prefect POSTGRES_DATABASE_SCHEME=postgresql+asyncpg \
    PREFECT_API_URL=https://prefect.yourdomain.com/api

dokku postgres:create prefect
dokku postgres:link prefect prefect -a PREFECT_API_DATABASE_CONNECTION

Read more about Prefect database connection for self-hosted production deployment.

CI/CD envs

In order to enable Dokku auto deployment after a commit / PR to main branch, you need to set Repo secrets in Github repo's settings:

  1. Open Settings -> Secrets and variables -> Actions -> New repository secret

  2. Set variables

  • SSH_PRIVATE_KEY (cat .ssh/id_rsa & copy-paste your key)
  • DOKKU_HOST (e.g. myserver.dokku.com)
  • DOKKU_APP_NAME (e.g. prefect)

How to enable Https

dokku letsencrypt:enable prefect

How to enable https basic auth

dokku plugin:install https://github.com/dokku/dokku-http-auth.git
dokku http-auth:enable prefect admin admin_password
dokku http-auth:add-allowed-ip app $(curl http://icanhazip.com/)
dokku ps:restart prefect

Don't forget to disable Cloudflare Proxy to allow add-allowed-ip do its job.
