This repository creates a lightweight, but still mostly capable Docker container called a "Hub" used to link up all the complexities of a standard application stack but still allow fine grained control over an applications configuration.
The image extends the full-chain radial/busyboxplus:git image with some logic
to allow for both static and dynamic configuration as well as some other
strategies for simplifying how to run the different parts of a full application
stack using Docker.
Check out the documentation here for more details.
Tunable environment variables; modify at runtime. Italics are defaults.
- $SUPERVISOR_REPO: [https://github.com/radial/config-supervisor.git] Repository location for default Supervisor daemon configuration.
- $SUPERVISOR_BRANCH: [master] Repository default branch.
- [$WHEEL_REPO[_APP1]...]: Additional repositories to download and merge with the default SUPERVISOR_REPO repository.
- [$WHEEL_BRANCH[_APP1]...]: Branches to pull for given WHEEL_REPO repositories.
- $UPDATES: [False|True] Update configuration from the selected WHEEL_REPO repositories (if any) on container restart.
- $PERMISSIONS_DEFAULT_DIR: ["755"] Default (recursive) directory permissions for /config, /data, and /log.
- $PERMISSIONS_DEFAULT_FILE: ["644"] Default (recursive) file permissions for files contained in /config, /data, and /log.
- $PERMISSIONS_EXCEPTIONS: [empty] A single string, separated by spaces,
containing a list of files/directories to chmod/chown.
- The format for a single entry: {<path to dir or file>}{:<octal mode>}[:<user>][:<group>]
- These values, separated by ':' are passed directly into
chownandchmodso things like/config/*work for directory contents and numeric user and group ids work as well. - Some examples:
/config/supervisor/conf.d/*:700/config/supervisor/supervisord.conf:700:root:root/config/supervisor/myprogram.conf:777:myprogramuser
