Docker Compose example

In this guide, we'll provide an example docker compose setup so that you can see how all of the bits hang together. We will demonstrate:

  • Authenticating to Quay.io
  • Running the PactFlow enterprise container
  • Persistent storage with a postgres database

Pre-requsites

1. Authenticating to Quay.ioā€‹

After obtaining valid robot credentials, you need to authenticate to Quay.io so that the docker engine is able to fetch our images.

docker login -u="<username>" -p="<password>" quay.io
docker pull quay.io/pactflow/enterprise

After this, you should have the latest PactFlow enterprise image on your machine. You can verify by executing

docker images quay.io/pactflow/enterprise

Which should produce an output such as:

> docker images quay.io/pactflow/enterprise
REPOSITORY                    TAG                 IMAGE ID            CREATED             SIZE
quay.io/pactflow/enterprise   2.0.0               32db429fda01        1 day ago           462MB # <- this guide applies to 2.x.x version
quay.io/pactflow/enterprise   latest              32db429fda01        1 day ago           462MB
quay.io/pactflow/enterprise   1.36.0              7f9b3c3aa50e        7 weeks ago         454MB

2. PactFlow license fileā€‹

The PactFlow on-premises version requires a license file to run. You should have received this from us during the on-boarding process. If not, please contact your Account Manager.

Save the license file into a temporary directory with the name pactflow-onprem.lic (it needs to be the same directory as used in step 3).

3. Startup PactFlow and supporting servicesā€‹

Save the below file as docker-compose.yml in the same directory as the license file and then run docker-compose up:

version: "3"

services:
  pactflow:
    image: quay.io/pactflow/enterprise:2.0.0
    depends_on:
      - postgres
      - redis
    environment:
      # This is set to localhost for this example but in a real deployment, this needs to be set to the actual URL of the application
      - PACTFLOW_BASE_URL=http://localhost
      # Insecure setting only for the purposes of this demo! Not to be used in production.
      - PACTFLOW_DATABASE_SSLMODE=disable
      # Insecure setting only for the purposes of this demo! Not to be used in production.
      - PACTFLOW_REQUIRE_HTTPS=false
      # Demo auth should only be used for demo purposes. Not to be used in production.
      - PACTFLOW_DEMO_AUTH_ENABLED=true
      # 'Allow all' for the webhook host whitelist should only be used for demo purposes. See docs for configuring this in production.
      - PACTFLOW_WEBHOOK_HOST_WHITELIST=/.*/
      - PACTFLOW_HTTP_PORT=9292
      # Link to the postgres database
      - PACTFLOW_DATABASE_URL=postgres://postgres:password@postgres/postgres
      - PACTFLOW_LOG_LEVEL=info
      - PACTFLOW_ADMIN_API_KEY=admin
      - PACTFLOW_MASTER_ENCRYPTION_KEY=thisissomerandombytes
      - PACTFLOW_COOKIE_SECRET=at-least-64-char-secret---------at-least-64-char-secret---------
      - PACT_BROKER_ADMIN_API_KEY=admin 
      - PACTFLOW_HTTP_LOGGING_ENABLED=true
      # Link to the redis cache
      - REDIS_URL=redis://redis:6379
    ports:
      - "80:9292"
    healthcheck:
      test: ["CMD", "supervisorctl", "status", "haproxy", "marko", "pactflow"]
      interval: 30s
      timeout: 10s
      retries: 3
    volumes:
      - ./pactflow-onprem.lic:/home/pactflow-onprem.lic

  postgres:
    image: postgres:13-alpine
    healthcheck:
      test: psql postgres --command "select 1" -U postgres
    volumes:
      - postgres-volume:/var/lib/postgresql/data
    environment:
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: password
      POSTGRES_DB: postgres

  redis:
    image: redis:latest

volumes:
  postgres-volume:

You can verify all services by running docker ps:

CONTAINER ID   IMAGE                                          COMMAND                  CREATED          STATUS                    PORTS                  NAMES
1cefdf8b1e1b   quay.io/pactflow/enterprise:2.0.0              "docker-entrypoint"      24 minutes ago   Up 24 minutes (healthy)   0.0.0.0:80->9292/tcp   tmp_pactflow_1
6bedae5936dc   redis:latest                                   "docker-entrypoint.sā€¦"   2 hours ago      Up 24 minutes             6379/tcp               tmp_redis_1
8b393d35a20c   postgres:13-alpine                             "docker-entrypoint.sā€¦"   9 days ago       Up 24 minutes (healthy)   5432/tcp               tmp_postgres_1

3. Login to PactFlowā€‹

Head to http://localhost in your browser, and choose to login with "PACTFLOW DEMO AUTH". Provide a name and email address to create your account and login. (The details don't need to be valid, and won't be used to send any emails.)

That's it šŸŽ‰.

For production use, you'll need to replicate this setup using a proper container orchestration tool, such as Kubernetes, AWS ECS/Fargate, AKS, GKE, Mesos etc, and your real Identity Provider.
