Why use Bitnami Images?

• Bitnami closely tracks upstream source changes and promptly publishes new versions of this image using our automated systems.
• With Bitnami images the latest bug fixes and features are available as soon as possible.
• Bitnami containers, virtual machines and cloud images use the same components and configuration approach - making it easy to switch between formats based on your project needs.
• All our images are based on minideb a minimalist Debian based container image which gives you a small base container image and the familiarity of a leading Linux distribution.
• All Bitnami images available in Docker Hub are signed with Docker Content Trust (DCT). You can use DOCKER_CONTENT_TRUST=1 to verify the integrity of the images.
• Bitnami container images are released daily with the latest distribution packages available.

This CVE scan report contains a security report with all open CVEs. To get the list of actionable security issues, find the "latest" tag, click the vulnerability report link under the corresponding "Security scan" field and then select the "Only show fixable" filter on the next page.

How to deploy Grafana in Kubernetes?

Deploying Bitnami applications as Helm Charts is the easiest way to get started with our applications on Kubernetes. Read more about the installation in the Bitnami Grafana Chart GitHub repository.

Bitnami containers can be used with Kubeapps for deployment and management of Helm Charts in clusters.

Why use a non-root container?

Non-root container images add an extra layer of security and are generally recommended for production environments. However, because they run as a non-root user, privileged tasks are typically off-limits. Learn more about non-root containers in our docs.

Supported tags and respective Dockerfile links

Learn more about the Bitnami tagging policy and the difference between rolling tags and immutable tags in our documentation page.

• 7, 7-debian-10, 7.2.0, 7.2.0-debian-10-r16, latest (7/debian-10/Dockerfile)

Get this image

The recommended way to get the Bitnami Grafana Docker Image is to pull the prebuilt image from the Docker Hub Registry.

$ docker pull bitnami/grafana:latest

To use a specific version, you can pull a versioned tag. You can view the list of available versions in the Docker Hub Registry.

$ docker pull bitnami/grafana:[TAG]

If you wish, you can also build the image yourself.

$ docker build -t bitnami/grafana:latest 'https://github.com/bitnami/bitnami-docker-grafana.git#master:7/debian-10'

Connecting to other containers

Using Docker container networking, a different server running inside a container can easily be accessed by your application containers and vice-versa.

Containers attached to the same network can communicate with each other using the container name as the hostname.

Using the Command Line

Step 1: Create a network

$ docker network create grafana-network --driver bridge

Step 2: Launch the grafana container within your network

Use the --network <NETWORK> argument to the docker run command to attach the container to the grafana-network network.

$ docker run --name grafana-node1 --network grafana-network bitnami/grafana:latest

Step 3: Run another containers

We can launch another containers using the same flag (--network NETWORK) in the docker run command. If you also set a name to your container, you will be able to use it as hostname in your network.

Configuration

Dev config

Update the grafana.ini configuration file in the /opt/bitnami/grafana/conf directory to override default configuration options. You only need to add the options you want to override. Config files are applied in the order of:

grafana.ini
default.ini

To enable development mode, edit the grafana.ini file and set app_mode = development.

Production config

Override the /opt/bitnami/grafana/conf/grafana.ini file mounting a volume.

$ docker run --name grafana-node -v /path/to/grafana.ini:/opt/bitnami/grafana/conf/grafana.ini bitnami/grafana:latest

After that, your configuration will be taken into account in the server's behaviour.

You can also do this by changing the docker-compose.yml file present in this repository:

grafana:
  ...
  volumes:
    - /path/to/grafana.ini:/opt/bitnami/grafana/conf/grafana.ini
  ...

Install plugins at initialization

When you start the Grafana image, you can specify a comma, semi-colon or space separated list of plugins to install by setting the env. variable GF_INSTALL_PLUGINS. The entries in GF_INSTALL_PLUGINS have two different formats:

• plugin_id: This will download the plugin with name plugin_id from the official Grafana plugins page.
• plugin_id=url: This will download the plugin with name plugin_id using the zip file specified in url. In case you want to skip TLS verification, set the variable GF_INSTALL_PLUGINS_SKIP_TLS to yes.

For Docker Compose, add the variable name and value under the application section:

grafana:
  ...
  environment:
    - GF_INSTALL_PLUGINS=grafana-kubernetes-app,worldpring=https://github.com/raintank/worldping-app/releases/download/v1.2.6/worldping-app-release-1.2.6.zip
  ...

For manual execution add a -e option with each variable and value:

$ docker run -d --name grafana -p 3000:3000 \
    -e GF_INSTALL_PLUGINS="grafana-kubernetes-app,worldpring=https://github.com/raintank/worldping-app/releases/download/v1.2.6/worldping-app-release-1.2.6.zip" \
    bitnami/grafana:latest

Grafana Image Renderer plugin

You can install the Grafana Image Renderer plugin to handle rendering panels and dashboards as PNG images. To install the plugin, follow the instructions described in the previous section.

As an alternative to install this plugin, you can use the Grafana Image Renderer container to set another Docker container for rendering and using remote rendering. We highly recommend to use this option. In the Docker Compose below you can see an example to use this container:

version: '2'

services:
  grafana:
    image: bitnami/grafana:6
    ports:
      - '3000:3000'
    environment:
      GF_SECURITY_ADMIN_PASSWORD: "bitnami"
      GF_RENDERING_SERVER_URL: "http://grafana-image-renderer:8080/render"
      GF_RENDERING_CALLBACK_URL: "http://grafana:3000/"
  grafana-image-renderer:
    image: bitnami/grafana-image-renderer:1
    ports:
      - '8080:8080'
    environment:
      HTTP_HOST: "0.0.0.0"
      HTTP_PORT: "8080"
      ENABLE_METRICS: 'true'

Logging

The Bitnami Grafana Docker image sends the container logs to the stdout. To view the logs:

$ docker logs grafana

You can configure the containers logging driver using the --log-driver option if you wish to consume the container logs differently. In the default configuration docker uses the json-file driver.

Maintenance

Upgrade this image

Bitnami provides up-to-date versions of grafana, including security patches, soon after they are made upstream. We recommend that you follow these steps to upgrade your container.

Step 1: Get the updated image

$ docker pull bitnami/grafana:latest

Step 2: Stop and backup the currently running container

Stop the currently running container using the command

$ docker stop grafana

Next, take a snapshot of the persistent volume /path/to/grafana-persistence using:

$ rsync -a /path/to/grafana-persistence /path/to/grafana-persistence.bkp.$(date +%Y%m%d-%H.%M.%S)

You can use this snapshot to restore the database state should the upgrade fail.

Step 3: Remove the currently running container

$ docker rm -v grafana

Step 4: Run the new image

Re-create your container from the new image, restoring your backup if necessary.

$ docker run --name grafana bitnami/grafana:latest

Notable Changes

6.7.3-debian-10-r28

• The GF_INSTALL_PLUGINS environment variable is not set by default anymore. This means it doesn't try to install the grafana-image-renderer plugin anymore unless you specify it. As an alternative to install this plugin, you can use the Grafana Image Renderer container.

6.7.2-debian-10-r18

• Grafana doesn't ship the grafana-image-renderer plugin by default anymore since it's not compatible with K8s distros with IPv6 disable. Instead, the GF_INSTALL_PLUGINS environment variable is set by default including this plugin so it's installed during the container's initialization, users can easily avoid it by overwriting the environment variable.
