How to write docker-compose setup? #45

Open askaribragimov opened 8 years ago

askaribragimov commented 8 years ago

It is a slight disappointing that docker-compose setup is completely nonexistent in the current official image.

Could you please provide information about how to specify the following docker-compose image:

version: '2'
services:
  c1:
    image: consul:0.7.2
    command: consul agent -dev -ui
    container_name: cs1
    ports:
        - "8500:8500"
  c2:
    image: consul:0.7.2
    command: consul agent -dev -join=cmain
    container_name: cs2
    links:
      - c1:cmain
  c3:
    image: consul:0.7.2
    command: consul agent -dev -join=cmain

Tried on Ubuntu 16.04 and Windows 10 (with all updates) with latest version of Docker.

docker logs cs2
==> Starting Consul agent...
==> Joining cluster...
==> 1 error(s) occurred:

i think thats fairly comprehensive: https://github.com/EugenMayer/consul-docker-stability-tests/tree/master/acls

it covers ACL setup, gossip setup and how to automtically configure clients with the runtime generated secrets

I wasn't aware of the link posted by @EugenMayer (https://github.com/EugenMayer/consul-docker-stability-tests/tree/master/acls), but I faced a similar challenge a while ago and I took notes of my setup. For anyone interested: https://www.marcolancini.it/2018/blog-offensive-infrastructure-consul/
