Grafana backup

Using wizzy and git, this simple tool pulls down the current dashboards and datasource configuration in Grafana. Then saves these into the git repo of your choice.

Use

Docker

Run as a docker file:

docker run --env GIT_NAME="Robot" --env GIT_EMAIL="robot@example.com" \
           --env GIT_TOKEN_USERNAME="<username>" --env GIT_TOKEN="<token>" \
           --env GIT_REPO_USERNAME="<username-of-repo>" --env GIT_REPO="<repo>" 
           --env GRAFANA_URL="http://grafana" --env GRAFANA_USERNAME="admin"
           --env GRAFANA_PASSWORD="admin" mt3593/grafana-backup:v0.0.1

Where GIT_REPO_USERNAME is the user name of the repo, so for this one it would be mt3593.

                valueFrom:

                    key: password
          restartPolicy: Never

This expects two secrets to be stored in kubernetes under the same namespace, grafana-backup-user and grafana-git-backup.

These can be created running the following commands with your values for username, token and password substituted in.

kubemonitoring create secret generic grafana-git-backup --from-literal=username=<username> --from-literal=token=<token>
kubemonitoring create secret generic grafana-backup-user --from-literal=username=<username> --from-literal=password=<password>
