panic: runtime error: invalid memory address or nil pointer dereference SIGSEGV related to Healthcheck #934

Closed

Description

Similar to #918 and #892 but slightly different cause.
This one is triggered by the healthcheck, this runs if healthcheck is removed.
This may have been fixed in #926 but I'm unable to test that yet.

version: '3'

services:

  postgres:
    image: postgres
    healthcheck:
      test: psql postgres --command "select 1"
    ports:
      - "5432:5432"
    environment:
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: password
      POSTGRES_DB: postgres

  broker_app:
    image: dius/pact-broker
    ports:
      - "80:80"
    links:
      - postgres
    environment:
      PACT_BROKER_DATABASE_USERNAME: postgres
      PACT_BROKER_DATABASE_PASSWORD: password
      PACT_BROKER_DATABASE_HOST: postgres
      PACT_BROKER_DATABASE_NAME: postgres
