Docker Canvas

Dockerized canvas to be used as a development environment.

Installation

Step 1: Install ansible

We use ansible to setup the local development environment. You can install it using the package manager available on your OS. We use Ubuntu in the example here.

apt-get install ansible

Step 2: Build the docker image

We build the docker image which will serve as the development environment for us.

./build-docker-image.sh

Step 3: Setup the local environment

We need to configure the environment before setting it up. We do this by modifying the environment parameters in ansible/playbooks/canvas/group_vars/all.

Parameter	Description
canvas_src	The location of the canvas source code on your local machine
canvas.admin_email	The canvas admin email address
canvas.admin_password	The canvas admin password
canvas.account_name	The canvas admin account name
canvas.stats_collection	The canvas stats collection policy

The ansible script creates a local canvas user on your machine. It then creates a folder /etc/canvas where we store all the configuration files related to canvas, apache and postgres. It also creates a symlink of the source code which points to the location provided by you in ansible/playbooks/canvas/group_vars/all.

You must run the deploy-local.sh script as sudo because it requires permissions to create the canvas user on your machine.

sudo ./deploy-local.sh

Once the deployment completes the canvas lms should be accessible on localhost.
