Cron Backup Docker

This docker container provides a backup cron job for a linked Virtuoso Triple Store.

Usage instructions

The container can be executed through the following example command:

docker run -d --link '<virtuoso container name>':virtuoso -e GIT_REPO='<ssh clone url>' -e GIT_EMAIL='<git email>' -e GIT_NAME='<git name>' -v '<.shh directory>':/root/.ssh '<docker image name>'

The container provides the following environment variables which could be set through the -e parameter:

• GIT_REPO needs to be a SSH URL like git@github.com:GeorgesAlkhouri/cron-backup-docker.git
• GIT_EMAIL needs to be set
• GIT_NAME needs to be set
• CRONTAB by default this is set to a midnight build (0 0 * * *)

To authenticate with the backup GitHub repository the container uses SSH. Therefore the hosts .ssh folder will be injected to /root/.ssh in the containers file system through:

-v '<.shh directory>':/root/.ssh

The hosts .ssh folder needs to contain the proper private ssh key and github.com needs to be added to the known_hosts file.

Finally the backup repository needs the public ssh key.
