How to spin up Pact Broker

Taken from: https://github.com/DiUS/pact_broker-docker/blob/master/POSTGRESQL.md

Start the docker machine:

docker-machine start default
eval $(docker-machine env default)

Create the Postgres container:

docker run --name pactbroker-db -e POSTGRES_PASSWORD=ThePostgresPassword -e POSTGRES_USER=admin -e PGDATA=/var/lib/postgresql/data/pgdata -v /var/lib/postgresql/data:/var/lib/postgresql/data -d postgres

Or start it:

docker start pactbroker-db

Access Postgres CLI:

docker run -it --link pactbroker-db:postgres --rm postgres sh -c 'exec psql -h "$POSTGRES_PORT_5432_TCP_ADDR" -p "$POSTGRES_PORT_5432_TCP_PORT" -U admin'

Create the DB user:

CREATE USER pactbrokeruser WITH PASSWORD 'TheUserPassword';
CREATE DATABASE pactbroker WITH OWNER pactbrokeruser;
GRANT ALL PRIVILEGES ON DATABASE pactbroker TO pactbrokeruser;

Create the Pact Broker container:

docker run --name pactbroker --link pactbroker-db:postgres -e PACT_BROKER_DATABASE_USERNAME=pactbrokeruser -e PACT_BROKER_DATABASE_PASSWORD=TheUserPassword -e PACT_BROKER_DATABASE_HOST=postgres -e PACT_BROKER_DATABASE_NAME=pactbroker -d  -p 9292:9292 pactfoundation/pact-broker

Or start it:

docker start pactbroker
