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. Closes-Bug: #1585911 Change-Id: I7fbcccb9d7ad168c5391e71326b205d074ab01ab Signed-off-by: Andras Kovi <akovi@nokia.com>

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
|
||||
<http://www.sqlite.org/omitted.html>`_.
|
||||
|
||||
|
||||
|
||||
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.
