Grafana docker image for Openshift Cluster

This build is based on the official Grafana docker image.

Theres several projects on Github that fixes this issue. But none of them reuses the run.sh script from the official image, or uses a diferent distribution to build the image.

In this project I use the official Dockerfile as a starting point and a modified version of their entrypoint script.

Why?

Official Grafana docker image needs root to execute run.sh. Since the container starts with other uid - witch is not root - it cannot execute chown directories.

chown: changing ownership of '/var/lib/grafana': Operation not permitted
chown: changing ownership of '/var/log/grafana': Operation not permitted

Configuration

The recommended way to configure this image is using environment variables, http://docs.grafana.org/installation/configuration/#using-environment-variables

For example:

- name: GF_DATABASE_URL
  value: "${GF_DATABASE_URL}"
- name: GF_SECURITY_ADMIN_USER
  value: "${GF_SECURITY_ADMIN_USER}"
- name: GF_SECURITY_ADMIN_PASSWORD
  value: "${GF_SECURITY_ADMIN_PASSWORD}"
- name: GF_USERS_ALLOW_SIGN_UP
  value: "${GF_USERS_ALLOW_SIGN_UP}"
- name: GF_AUTH_ANONYMOUS_ENABLED
  value: "${GF_AUTH_ANONYMOUS_ENABLED}"
- name: GF_AUTH_ANONYMOUS_ORG_ROLE
  value: "${GF_AUTH_ANONYMOUS_ORG_ROLE}"
