Description

Minimal image with jinja templates rendered by tmpld. This image uses a custom, minimal version of Debian Linux.

Build Environment

Build environment variables are often used in the build script to bump version numbers and set other options during the docker build phase. Their values can be overridden using a build argument of the same name.

• MONSTER_APPS
• NODE_VERSION
• TMPLD_VERSION

[todo] Finish describing these.

The following variables are standard in most of our dockerfiles to reduce duplication and make scripts reusable among different projects:

• APP: monster-ui
• USER: monster-ui
• HOME /opt/monster-ui

Run Environment

Run environment variables are used in the entrypoint script to render configuration templates, perform flow control, etc. These values can be overridden when inheriting from the base dockerfile, specified during docker run, or in kubernetes manifests in the env array.
