Mirror a git repository periodically from one remote to another.

docker run \
  -e ORIGINAL_REPO="https://USER:[email protected]/owner/repo" \
  -e MIRROR_REPO="https://USER:[email protected]/mirrors/owner/repo.git" \
  -e CRON_STRING="*/5\t*\t*\t*\t*" \
  davidknezic/git-mirror

This is your original repository.

It's mandatory to provide this value.

This is the repository you want to mirror to. Please note that all the previous commits will be irreversibly replaced by the original repository. (🚨)

It's mandatory to provide this value.

This configuration value defines how often the original repository should get mirrored into the other one.

It follows the Cron standard, in which you can set up the periodicity using 5 values, of which each one is separated by a tab character (\t).

For custom intervals please have a look at this handy Cron expression reference.

The default is every 5 minutes. (*/5 * * * *, separated with tabs \t)

In some cases you might be forced to provide environment variables to this container. Common scenarios are having to configure git to use a proxy or fixing the problem when pushing to a server with an invalid SSL certificate.

In both those cases you can simply provide additional environment variables to the container, like this:

docker run \
  ... \
  -e HTTP_PROXY=http://proxy:8080 \
  -e HTTPS_PROXY=http://proxy:8080 \
  davidknezic/git-mirror

or

docker run \
  ... \
  -e GIT_SSL_NO_VERIFY=true \
  davidknezic/git-mirror

However, please note that the last example is considered very insecure.

Find other possibilities in this git environment variable reference.
