Why use Bitnami Secure Images?

Those are hardened, minimal CVE images built and maintained by Bitnami. Bitnami Secure Images are based on the cloud-optimized, security-hardened enterprise OS Photon Linux. Why choose BSI images?

  • Hardened secure images of popular open source software with Near-Zero Vulnerabilities
  • Vulnerability Triage & Prioritization with VEX Statements, KEV and EPSS Scores
  • Compliance focus with FIPS, STIG, and air-gap options, including secure bill of materials (SBOM)
  • Software supply chain provenance attestation through in-toto
  • First class support for the internets favorite Helm charts

Each image comes with valuable security metadata. You can view the metadata in our public catalog here. Note: Some data is only available with commercial subscriptions to BSI.

Get this image

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

docker pull bitnami/clickhouse-keeper: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/clickhouse-keeper:[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 .

Persisting your application

If you remove the container all your data will be lost, and the next time you run the image the database will be reinitialized. To avoid this loss of data, you should mount a volume that will persist even after the container is removed.

For persistence you should mount a directory at the /bitnami/clickhouse-keeper path. If the mounted directory is empty, it will be initialized on the first run.

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.

Configuration

ClickHouse Keeper can be configured via environment variables or using a configuration file (keeper_config.xml). If a configuration option is not specified in either the configuration file or in an environment variable, ClickHouse Keeper uses its internal default configuration.

Configuration overrides

The configuration can easily be setup by mounting your own configuration overrides on the directory /bitnami/clickhouse-keeper/etc/config.d or /bitnami/clickhouse-keeper/etc/users.d:

docker run --name clickhouse-keeper \
    --volume /path/to/override.xml:/bitnami/clickhouse-keeper/etc/config.d/override.xml:ro \
    bitnami/clickhouse-keeper:latest

or using Docker Compose:

version: '2'

services:
  clickhouse-keeper:
    image: bitnami/clickhouse-keeper:latest
    volumes:
      - /path/to/override.xml:/bitnami/clickhouse-keeper/etc/config.d/override.xml:ro

Check the official ClickHouse Keeper configuration documentation for all the possible overrides and settings.
