Docker-Cantaloupe

Provides a basic docker container for 🍈 with all the image tools installed. Based on the Ubuntu 16.04 image.

Environment Variables

User

Inside the container Cantaloupe is run as a user named Cantaloupe. The UID and GID of this user can be controlled by setting the following environment variables:

  • CANTALOUPE_UID
  • CANTALOUPE_GID

Both of these default to 999.

Java

The arguements passed to Java when starting Cantaloupe can be controlled with:

  • JAVA_OPTS

Default: -Xmx500m

Cantaloupe.properties

The path that cantaloupe looks for cantaloupe.properties is configured by:

  • PROPERTIES_FILE.

Default: /cantaloupe/cantaloupe.properties

You can change this if you want to mount your own cantaloupe.properties inside of the container. By default almost all of the cantaloupe.properties configuration is customized using environment variables. You can find the details of the environment variables you can set here.

docker build -t cantaloupe .

Paths

Most of the paths are customizable using environment variables, but by default they are all located in /cantaloupe:

  • Cache: /cantaloupe/cache
  • Logs: /cantaloupe/logs
  • Image Source: /cantaloupe/images
