edX Devstack

Get up and running quickly with edX services.

If you are seeking info on the Vagrant-based devstack, please see https://openedx.atlassian.net/wiki/display/OpenOPS/Running+Devstack. This project is meant to replace the traditional Vagrant-based devstack with a multi-container approach driven by Docker Compose. It is still in the alpha/beta testing phase. Support for this project is limited at the moment, so it may take a while to respond to issues.

You should run any Make targets described below on your local machine, not from within a VM.

Prerequisites

This project was developed and tested using Docker 1.13+. If you are using macOS, please use Docker for Mac. Previous Mac-based tools (e.g. boot2docker) are not supported.

Docker for Windows may work but has not been tested and is not supported.

Getting Started

All of the services can be run by following the steps below. Note that since we are running many containers, you should configure Docker with a sufficient amount of resources. Our testing found that configuring Docker for Mac with 2 CPUs and 4GB of memory works well.

  1. The Docker Compose file mounts a host volume for each service's executing code. The host directory is expected to be a sibling of this directory. For example, if this repo is cloned to ~/workspace/devstack, host volumes will be expected in ~/workspace/course-discovery, ~/workspace/ecommerce, etc. These repos can be cloned with the command below.

    make clone

  2. Run the provision command, if you haven't already, to configure the various services with superusers (for development without the auth service) and tenants (for multi-tenancy).

    The username and password for the superusers are both "edx". You can access the services directly via Django admin at the /admin/ path, or login via single sign-on at /login/.

    make devstack.provision

  3. Start the services. By default this command will use host directories for source code. This is known to be slow on macOS. macOS users should follow the steps below for Docker Sync to avoid this performance hit.

    make devstack.start

After the services have started, if you need shell access to one of the services, run make devstack.open.<service>. For example to access the Catalog/Course Discovery Service, you can run:

make devstack.open.discovery

Docker Sync

Docker for Mac has known filesystem issues that significantly decrease performance. In order to mitigate these issues, we use Docker Sync to synchronize file data from the host machine to the containers. Follow the steps below to setup Docker Sync.

  1. Ensure all containers are stopped.

    make devstack.stop

  2. Follow the Docker Sync installation instructions.

  3. Run Docker Sync and devstack.

    make devstack.start.sync

Usernames and Passwords

The provisioning script creates a Django superuser for every service.

Email: [email protected]
Username: edx
Password: edx

The LMS also includes demo accounts. The passwords for each of these accounts is edx.

Username Email
audit [email protected]
honor [email protected]
staff [email protected]
verified [email protected]

Service URLs

Each service is accessible at localhost on a specific port. The table below provides links to the homepage of each service. Since some services are not meant to be user-facing, the "homepage" may be the API root.

Service URL
Credentials http://localhost:18150/api/v2/
Catalog/Discovery http://localhost:18381/api-docs/
E-Commerce/Otto http://localhost:18130/dashboard/
LMS http://localhost:18000/
Studio/CMS http://localhost:18010/

Useful Commands

Sometimes you may need to restart a particular application server. Rather than restarting the entire devstack or the individual container, you can instruct Supervisor to restart just the nginx and application servers with one command.

If you are already working in the shell of a container run:

/edx/app/supervisor/venvs/supervisor/bin/supervisorctl restart all

Alternatively, if you are not working from a shell inside a container run:

docker exec -t edx.devstack.<service> bash -c '/edx/app/supervisor/venvs/supervisor/bin/supervisorctl restart all'

<service> should be replaced with one of the following:

  • credentials
  • discovery
  • ecommerce
  • edxapp

Remaining Work

There is still work to be done before this is ready for full release to the Open edX community. Here are the major items:
