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 that gives you a small base container image and the familiarity of a leading Linux distribution- or scratch -an explicitly empty image-.
- All Bitnami images available in Docker Hub are signed with Docker Content Trust (DCT). You can use
DOCKER_CONTENT_TRUST=1to verify the integrity of the images. - Bitnami container images are released on a regular basis with the latest distribution packages available.
Looking to use JanusGraph in production? Try VMware Tanzu Application Catalog, the commercial edition of the Bitnami catalog.
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.
Subscribe to project updates by watching the bitnami/containers GitHub repo.
Get this image
The recommended way to get the Bitnami JanusGraph Docker Image is to pull the prebuilt image from the Docker Hub Registry.
docker pull REGISTRY_NAME/bitnami/janusgraph: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 REGISTRY_NAME/bitnami/janusgraph:[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 REGISTRY_NAME/bitnami/APP:latest .

| Name | Description | Value |
|---|---|---|
JANUSGRAPH_BASE_DIR | Base path for JanusGraph files. | ${BITNAMI_ROOT_DIR}/janusgraph |
JANUSGRAPH_VOLUME_DIR | JanusGraph directory for persisted files. | ${BITNAMI_VOLUME_DIR}/janusgraph |
JANUSGRAPH_DATA_DIR | JanusGraph data directory. | ${JANUSGRAPH_VOLUME_DIR}/data |

Additionally, any environment variable beginning with JANUSGRAPH_CFG_ will be mapped to its corresponding JanusGraph key. For example, use JANUSGRAPH_CFG_STORAGE_BACKEND in order to set storage.backed or JANUSGRAPH_CFG_CACHE_DB__CACHE in order to configure cache.db-cache.
Using mounted configuration
The image looks for configuration files (janusgraph.properties, gremlin-server.yaml) in the /bitnami/janusgraph/conf/, this can be changed by setting the JANUSGRAPH_MOUNTED_CONF_DIR environment variable.
docker run --name janusgraph -v /path/to/janusgraph.properties:/bitnami/janusgraph/conf/janusgraph.properties -v /path/to/gremlin-server.yaml:/bitnami/janusgraph/conf/gremlin-server.yaml REGISTRY_NAME/bitnami/janusgraph:latest
