Wetopi rabbitmq Dockerfile

This repository contains Dockerfile based on official rabbitmq with a new startup script to let us perform user credentials and vhost setup during container start.

This setup script outside our image lets run rabbitmq with credentials based on our environment variables.

Base Docker Image

• rabbitmq:3-management

What for

This image calls a new docker-entrypoint.sh wich introduces a new setup step:

• When docker-entrypoint.sh is callen with command rabbitmq-server
• Then docker-entrypoint.sh runs docker-setup.sh

This docker-setup.sh performs:

• Delete guest user
• Create admin user with password from environment var RABBITMQ_PASS
• Create RABBITMQ_USER setting same RABBITMQ_PASS for RABBITMQ_VIRTUALHOST
• Save a token file in homedir /var/lib/rabbitmq/.docker-setup-done to do not repeat the setup

This last user is the one we will use in wetopi app.

How to use this image:

https://registry.hub.docker.com/u/library/wetopi/rabbitmq/

Installation

1. Install Docker.

2. Download automated build from public Docker Hub Registry: docker pull wetopi/rabbitmq

3. Build docker build -t="wetopi/rabbitmq" github.com/wetopi/rabbitmq . (alternatively, you can build an image from Dockerfile: docker build -t="wetopi/rabbitmq" .)

Run container:

docker run -d -h rabbitmq.wetopi -e RABBITMQ_NODENAME=rabbitmq -e RABBITMQ_USER=myuser -e RABBITMQ_PASS=mysecret -e RABBITMQ_VIRTUALHOST=/wetopi --name rabbitmq wetopi/rabbitmq

NOTE: in case of restarting from an existing mnesia database (in our case we are using rabbitmqdata with a persisted volume), its important to use always tell docker to use same hostname, i.e -h rabbitmq.wetopi
