Request for docker-compose example with pact-broker

[shrikeh]

Hi there,

Been trying to get the stub-server working with a local pact-broker for quick prototyping. However, I appear to always get the following:

15:57:54 [INFO] Fetching path '/' from pact broker
15:57:54 [ERROR] There were errors loading the pact files.
15:57:54 [ERROR]   - IoError(Failed to access pact broker path '/' - error sending request for url (http://pact-broker:9292/): error trying to connect: tcp connect error: Connection refused (os error 111). URL: 'http://pact-broker:9292/')
ERROR: 3

Here is my abridged docker-compose.yml file:

---
version: "3.9"

services:
  pact-broker:
    image: pactfoundation/pact-broker:2.81.0.1
    environment:
      PACT_BROKER_DATABASE_HOST:                                   "pact-broker-db"
      PACT_BROKER_DATABASE_NAME:                                   "${PACT_BROKER_DB_NAME:?err}"
      PACT_BROKER_DATABASE_USERNAME:                          "${PACT_BROKER_DB_USERNAME:?err}"
      PACT_BROKER_DATABASE_PASSWORD:                         "${PACT_BROKER_DB_PASSWORD:?err}"
      PACT_BROKER_DATABASE_PORT:                                    "${PACT_BROKER_DB_PORT:-5432}"
      PACT_BROKER_DATABASE_CONNECT_MAX_RETRIES: "10"
      PACT_BROKER_PORT:                                                        "${PACT_BROKER_PORT:-9292}"
    depends_on:
      - pact-broker-db
    expose:
      - "${PACT_BROKER_PORT:-9292}"
    ports:
      - "9010:${PACT_BROKER_PORT:-9292}"
  pact-broker-db:
    image: postgres:13.4-alpine3.14
    restart: always
    healthcheck:
      test: "psql postgres --command 'select 1' -U ${PACT_BROKER_DB_USERNAME:?err}"
    volumes:
      - pact-postgres:/var/lib/postgresql/data
    environment:
      POSTGRES_DB:       "${PACT_BROKER_DB_NAME:?err}"
      POSTGRES_USER:     "${PACT_BROKER_DB_USERNAME:?err}"
      POSTGRES_PASSWORD: "${PACT_BROKER_DB_PASSWORD:?err}"
    expose:
      - "${PACT_BROKER_DB_PORT:-5432}"
  pact-stub:
    image: pactfoundation/pact-stub-server:v0.4.4
    command: "--port ${PACT_STUB_PORT:?err}"
    environment:
      PACT_BROKER_BASE_URL: "http://pact-broker:${PACT_BROKER_PORT:-9292}/"
    volumes:
      # Not used when pact-broker is running
      - ./tests/pacts:/pacts:ro
    depends_on:
      - pact-broker
    ports:
      - "8082:${PACT_STUB_PORT:?err}"
volumes:
  pact-postgres:

For the purposes of aiding, pact-broker starts fine, and indeed the following curl to the assigned ports also works fine:

$> curl http://localhost:8080

It could be this:

ports:
      - "9010:${PACT_BROKER_PORT:-9292}"

Is that not mapping the internal port (defined by ${PACT_BROKER_PORT:-9292}) to 9010

Here is a working docker compose example:

version: "3.9"

services:
  pact-broker:
    image: pactfoundation/pact-broker:2.81.0.1
    environment:
      PACT_BROKER_DATABASE_URL:                              "postgres://postgres:password@pact-broker-db/postgres"
      PACT_BROKER_PORT:                                      "9292"
      PACT_BROKER_BASE_URL: 'https://localhost http://localhost http://localhost:9292 http://pact-broker:9292'
    depends_on:
      - pact-broker-db
    expose:
      - "9292"
    ports:
      - "9292:9292"
  pact-broker-db:
    image: postgres:13.4-alpine3.14
    restart: always
    healthcheck:
      test: "psql postgres --command 'select 1' -U postgres"
    volumes:
      - pact-postgres:/var/lib/postgresql/data
    environment:
      POSTGRES_DB:       postgres
      POSTGRES_USER:     postgres
      POSTGRES_PASSWORD: password
    expose:
      - "5432"
  pact-stub:
    image: pactfoundation/pact-stub-server:v0.4.4
    entrypoint: "/bin/bash -c 'sleep 5 && ./pact-stub-server --port 8082'"
    environment:
      PACT_BROKER_BASE_URL: "http://pact-broker:9292/"
    volumes:
      # Not used when pact-broker is running
      - ./tests/pacts:/pacts:ro
    depends_on:
