What is Grafana?
Grafana is an open source, feature rich metrics dashboard and graph editor for Graphite, Elasticsearch, OpenTSDB, Prometheus and InfluxDB.
TL;DR;
$ docker run --name grafana bitnami/grafana:latest
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.
- Bitnami images are built on CircleCI and automatically pushed to the Docker Hub.
- 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.
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
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 Blacbox_exporter 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
Create a custom.ini in the conf (/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
custom.ini
In your custom.ini uncomment (remove the leading ;) sign. And set app_mode = development.
Production config
Override the /opt/bitnami/grafana/conf/grafana.ini file by [Mounting a volume](#Mounting a volume)
Mounting a volume
Check the [Persisting your data](#Persisting your application) section to add custom volumes to the Grafana container
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
