⚠️ Important Notice: Upcoming changes to the Bitnami Catalog

Beginning August 28th, 2025, Bitnami will evolve its public catalog to offer a curated set of hardened, security-focused images under the new Bitnami Secure Images initiative. As part of this transition:

• Granting community users access for the first time to security-optimized versions of popular container images.
• Bitnami will begin deprecating support for non-hardened, Debian-based software images in its free tier and will gradually remove non-latest tags from the public catalog. As a result, community users will have access to a reduced number of hardened images. These images are published only under the “latest” tag and are intended for development purposes
• Starting August 28th, over two weeks, all existing container images, including older or versioned tags (e.g., 2.50.0, 10.6), will be migrated from the public catalog (docker.io/bitnami) to the “Bitnami Legacy” repository (docker.io/bitnamilegacy), where they will no longer receive updates.
• For production workloads and long-term support, users are encouraged to adopt Bitnami Secure Images, which include hardened containers, smaller attack surfaces, CVE transparency (via VEX/KEV), SBOMs, and enterprise support.

These changes aim to improve the security posture of all Bitnami users by promoting best practices for software supply chain integrity and up-to-date deployments. For more details, visit the Bitnami Secure Images announcement.

Why use Bitnami Secure Images?

• Bitnami Secure Images and Helm charts are built to make open source more secure and enterprise ready.
• Triage security vulnerabilities faster, with transparency into CVE risks using industry standard Vulnerability Exploitability Exchange (VEX), KEV, and EPSS scores.
• Our hardened images use a minimal OS (Photon Linux), which reduces the attack surface while maintaining extensibility through the use of an industry standard package format.
• Stay more secure and compliant with continuously built images updated within hours of upstream patches.
• 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.
• Hardened images come with attestation signatures (Notation), SBOMs, virus scan reports and other metadata produced in an SLSA-3 compliant software factory.

Only a subset of BSI applications are available for free. Looking to access the entire catalog of applications as well as enterprise support? Try the commercial edition of Bitnami Secure Images today.

How to deploy Grafana Image Renderer 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.

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.

You can see the equivalence between the different tags by taking a look at the tags-info.yaml file present in the branch folder, i.e bitnami/ASSET/BRANCH/DISTRO/tags-info.yaml.

Get this image

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

docker pull bitnami/grafana-image-renderer: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-image-renderer:[TAG]

If you wish, you can also build the image yourself by cloning the repository, changing to the directory containing the Dockerfile and executing the docker build command. Remember to replace the APP, VERSION and OPERATING-SYSTEM path placeholders in the example command below with the correct values.

git clone https://github.com/bitnami/containers.git
cd bitnami/APP/VERSION/OPERATING-SYSTEM
docker build -t bitnami/APP:latest .

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 my-network --driver bridge

Step 2: Launch the grafana-image-renderer container within your network

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

docker run -d --name grafana-image-renderer \
    --env HTTP_PORT="8080" \
    --env HTTP_HOST="0.0.0.0" \
    --network my-network \
    bitnami/grafana-image-renderer:latest

Step 3: Launch a Grafana container within your network that uses grafana-image-renderer as rendering service

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

docker run -d --name grafana \
    --network my-network \
    --publish 3000:3000 \
    --env GF_RENDERING_SERVER_URL="http://grafana-image-renderer:8080/render" \
    --env GF_RENDERING_CALLBACK_URL="http://grafana:3000" \
    --env GF_LOG_FILTERS="rendering:debug" \
    bitnami/grafana:latest

Configuration

You can customize Grafana Image Renderer settings by replacing the default configuration file with your custom configuration, or using environment variables.

Environment variables

Customizable environment variables

Configuration file

The image looks for a config.json file in /opt/bitnami/grafana-image-renderer/conf/. You can mount a volume at /opt/bitnami/grafana-image-renderer/conf/ and copy/edit the config.json file in the /path/to/grafana-image-renderer-conf/ path. The default configurations will be populated to the conf/ directory if it's empty.

/path/to/grafana-image-renderer-conf/
└── config.json

0 directories, 1 file

Step 1: Run the Grafana Image Renderer container

Run the Grafana Image Renderer container, mounting a directory from your host.

docker run --name grafana-image-renderer bitnami/grafana-image-renderer:latest

docker run --name grafana-image-renderer -v ${PWD}/path/to/grafana-image-renderer-conf:/opt/bitnami/grafana-image-renderer/conf/ bitnami/grafana-image-renderer:latest

Step 2: Edit the configuration

Edit the configuration on your host using your favorite editor.

vi /path/to/grafana-image-renderer-conf/config.json

Step 3: Restart Grafana Image Renderer

After changing the configuration, restart your Grafana Image Renderer container for changes to take effect.

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

FIPS configuration in Bitnami Secure Images

The Bitnami Grafana Image Renderer Docker image from the Bitnami Secure Images catalog includes extra features and settings to configure the container with FIPS capabilities. You can configure the next environment variables:

• OPENSSL_FIPS: whether OpenSSL runs in FIPS mode or not. yes (default), no.

Logging

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

docker logs grafana-image-renderer

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.
