Andras Kovi 7b6d76659a Fixes the Mistral Docker image

Refactored to make the docker stuff self contained and removed the
unnecessary files from the root directory. Also created a readme file to
concretize how this feature works.

Also added an example script to set up Mistral with MySQL.

Using Mistral with docker

In order to minimize the work needed to the current Mistral code, or be able to spin up independent or networked Mistral instances in seconds, docker containers are a very good option. This guide describes the process to launch an all-in-one Mistral container.

Docker installation

In order to install the latest docker engine, run:

curl -fsSL https://get.docker.com/ | sh

If you are behind a proxy, additional configuration may be needed to be able to execute further steps in the setup process. For detailed information on this process, check out the official guide at.

Build the Mistral image

The build.sh script takes care of creating the mistral-all image locally.

Running Mistral

Start a RabbitMQ container:

docker run -d --name rabbitmq rabbitmq

Start Mistral:

docker run -d -p 8989:8989 --name mistral mistral-all

To execute commands inside the container:

docker exec -it mistral bash

E.g. to list workflows, issue:

mistral workflow-list

Running Mistral with MySQL

Other than the simplest use cases will very probably fail with various errors due to the default Sqlight database. It is highly recommended that, for example, MySQL is used as database backend.

The start_mistral_rabbit_mysql.sh script sets up a rabbitmq container, a mysql container and a mistral container to work together.

Check out the script for more detail.
