    image: pomerium/pomerium:latest
    environment:
      # Generate new secret keys. e.g. `head -c32 /dev/urandom | base64`
      - COOKIE_SECRET=<reducted>

# Run

# Edit hosts file

Add following entry to /etc/hosts:

127.0.0.1 identityprovider

# Start services

$ docker-compose up -d identityprovider
$ : wait identityprovider up
$ docker-compose up -d

Now accessing to https://verify.localhost.pomerium.io and you will be redireted to OIDC server for authentication.
