git-updater

Periodically update a directory from a git repository.

This container is useful to maintain an up to date set of files in a directory (or volume of another container), without teaching another application how to understand GIT.

Usage

usage:  docker run deweysasser/git-updater [options] [commands]
   or 
        docker run -d deweysasser/git-updater  [options] -loop [commands]
   or 
        docker run -it deweysasser/git-updater  -shell [args...]

options are:

-help -- this text
-shell -- invoke a bash shell with the remaining arguments
-loop -- loop continously
-source SOURCE -- set the source dir to SOURCE.  Currently empty
-signed -- if set, copy files from the latest signed tag.  Currently 'false'.
-target TARGET -- set the target dir to TARGET.  Currently ''.
-keys KEYS -- set the keys dir to KEYS.  Currently ''.
-sleep SLEEP -- number of seconds to sleep between polls.  Currently '60'.
-sandbox SANDBOX -- the location of the git sandbox used to poll
-branch BRANCH -- branch of the git repository to clone and/or examine for signed tags
-dir DIR -- directory within the repositor to copy to the TARGET

You may also specify each of SOURCE, TARGET and KEYS as environment
variables as well as set the value of SIGNED to 'false' (to avoid
signatures) or anything else (to check signatures)

You may optionally specificy a COMMAND to run after the update (and
signature check, if any) is successful.

This image will generate an SSH key on run and report it to the docker console. If you'd like to use an existing SSH key, arrange for it to be in /root/.ssh/id_rsa

If you are checking GIT signatures, place GPG keys (suitable for gpg --import) in /keys or the

Example

 docker run -d --name xymon deweysasser/xymon

 docker run -d deweysasser/git-updater -volumes-from xymon -d SOURCE=git@somewhere:/my/xymon-conf.git -e TARGET=/etc/xymon -loop
