MediaGoblin

A basic container for a private MediaGoblin media server (https://mediagoblin.org/), including Nginx and uWSGI. Assumes a separate PostgreSQL database for persistence, and an email host for sending email notifications.

Hosted at https://projects.torsion.org/witten/mediagoblin-docker

Environment variables

• NOTIFICATION_EMAIL: From address for MediaGoblin notification emails.
• EMAIL_HOSTNAME: Hostname used to send outgoing notification emails.
• EMAIL_PORT: Port number used to send outgoing notification emails.
• EMAIL_USERNAME: Username used to connect to outgoing email host.
• EMAIL_PASSWORD: Password used to connect to outgoing email host.
• EMAIL_TLS_SSL: "true" or "false" for using TLS/SSL encryption for sending emails.
• EMAIL_STARTTLS: "true" or "false" for using STARTTLS encryption for sending emails.
• DATABASE_URL: Connection string for database to use for persistence, including credentials. See example below.

Volumes

• /app/user_dev: Location to store user media uploads.

Ports

• 80: Only listens on port 80 for HTTP. Intended to be used in conjunction with an external reverse proxy like https://hub.docker.com/r/jwilder/nginx-proxy/ to provide HTTPS or anything else that's needed.

User management

Since this image is for running a private MediaGoblin server, user self-registration is disabled. So, to add a user, first exec into the running Docker image:

$ sudo docker exec -it mediagoblin bash

Where mediagoblin is the name of your running Docker container. If you don’t know the name to use, try looking in docker ps output.

Then, add a user (follow the prompts):

# su - mediagoblin
$ gmg --conf_file /app/mediagoblin_local.ini adduser

Finally, if you want to make the new user into an admin user:

$ gmg --conf_file /app/mediagoblin_local.ini makeadmin username

Where username corresponds to the user you added above.
