The bare minimum ClickHouse Docker image.
It is intended as a showcase to check the amount of implicit dependencies of ClickHouse on the OS in addition to the OS kernel.
Example usage:
./prepare
docker build --tag clickhouse-bare .
Run clickhouse-local:
docker run -it --rm --network host clickhouse-bare /clickhouse local --query "SELECT 1"
Run clickhouse-client in interactive mode:
docker run -it --rm --network host clickhouse-bare /clickhouse client
Run clickhouse-server:
docker run -it --rm --network host clickhouse-bare /clickhouse server
It can be also run in chroot instead of Docker (first edit the prepare script to enable proc):
sudo chroot . /clickhouse server
What does it miss?
- Creation of
clickhouseuser to run the server. - VOLUME for server.
- For most details, see other docker images for comparison.
A binary built with musl (cmake -DCMAKE_TOOLCHAIN_FILE=cmake/linux/toolchain-x86_64-musl.cmake) needs none of the files installed by the prepare script: it is statically linked, CA certificates are embedded into the binary and used when none are found on the filesystem, DNS works without /etc/resolv.conf (well-known public DNS resolvers are used when the file does not exist), and localhost resolves to loopback per RFC 6761 even without /etc/hosts.
