Run-in-docker manual

The main purpose of the run-in-docker script is to provide a convenient way to create a local setup of RefStack inside a Docker container. It should be helpful for new developers and also for testing new features.

Requirements:

• Docker >= 1.6 (How to update on Ubuntu)

How to use:

Just run the run-in-docker script, but is important to first set env[REFSTACK_HOST] with the public host/IP for your local API. If you want to test RefStack with OpenStackid you should point a valid local alias here. For example:

export REFSTACK_HOST=myrefstack.com

By default 127.0.0.1 is used.

After it completes, check that the site is running on https://127.0.0.1.

The script will build a RefStack docker image with all dependencies, and will run a container from this image. By default, RefStack will run inside this container. You also can run run-in-docker bash to get access into the container. If you stop the RefStack server by pressing 'Ctrl-C', the container is kept alive and will be re-used next time.

You can customize the RefStack API config by editing docker/templates/refstack.conf.tmpl. It is a bash template, so you can use ${SOME_ENV_VARIABLE} in it.

This script can make the reviewing process much easier because it creates separate containers for each review. Containers get names in the form refstack_{REVIEW-TOPIC}. Database schema changes are automatically handled, too, where the script creates a data container for each database revision (refstack_data_{DATA-BASE-REVISON}) and reuses it where possible. For example, if a new review uses an existing database revision, that database container will be used.

Available script options:

• -r Force delete the RefStack container and run it again. This will update the RefStack config from template noted above.
• -i Run a container with isolated MySQL data. By default MySQL data is stored in a refstack_data_{DATA-BASE-REVISON} container. It reuses this container if such one exists. If you want to drop the DB data, just execute sudo docker rm refstack_data_{DATA-BASE-REVISON}.
• -b Force delete RefStack image and build it again. This rebuilds the Python and JS environment for RefStack.
• -d Turn on debug information.
• -h Print usage message.

Useful in-container commands/aliases:

• api-up - sync project and run the RefStack API
• api-init-db - initialize the RefStack database
• api-db-version - get current migration version of the RefStack database
• api-sync - sync project files in the container with the project files on the host
• activate - activate the python virtual env
• mysql - open the MySQL console
