The default Clickhouse listen_host is 127.0.0.1 and port is 8123.

start server instance

To run with Docker and allow empty passwords:

docker run -d --ulimit nofile=262144:262144 cgr.dev/chainguard/clickhouse:latest

By default, ClickHouse will be accessible only via the Docker network. See the networking section below.

By default, starting above server instance will be run as the default user without password.

Users and Directories

By default, this image runs as a non-root user named clickhouse with a uid of 101 and a home directory of /home/clickhouse.

Volumes

Typically you may want to mount the following folders inside your container to achieve persistency:

• /var/lib/clickhouse/ - main folder where ClickHouse stores the data
• /var/log/clickhouse-server/ - logs

docker run -d \
    -v $(realpath ./ch_data):/var/lib/clickhouse/ \
    -v $(realpath ./ch_logs):/var/log/clickhouse-server/ \
    --ulimit nofile=262144:262144 cgr.dev/chainguard/clickhouse:latest

You may also want to mount:

• /etc/clickhouse-server/config.d/*.xml - files with server configuration adjustmenets
• /etc/clickhouse-server/users.d/*.xml - files with user settings adjustmenets
• /docker-entrypoint-initdb.d/ - folder with database initialization scripts (see below).

What are Chainguard Containers?

Chainguard Containers are minimal container images that are secure by default.

In many cases, the Chainguard Containers tagged as :latest contain only an open-source application and its runtime dependencies. These minimal container images typically do not contain a shell or package manager. Chainguard Containers are built with Wolfi, our Linux undistro designed to produce container images that meet the requirements of a more secure software supply chain.

The main features of Chainguard Containers include:

• Minimal design, without unnecessary software bloat
• Daily builds to ensure container images are up-to-date with available security patches
• High quality build-time SBOMs attesting to the provenance of all artifacts within the image
• Verifiable signatures provided by Sigstore
• Reproducible builds with Cosign and apko (read more about reproducibility)

For cases where you need container images with shells and package managers to build or debug, most Chainguard Containers come paired with a -dev variant.

Although the -dev container image variants have similar security features as their more minimal versions, they feature additional software that is typically not necessary in production environments. We recommend using multi-stage builds to leverage the -dev variants, copying application artifacts into a final minimal container that offers a reduced attack surface that won’t allow package installations or logins.
