# user/group precreated explicitly with fixed uid/gid on purpose.
# It is especially important for rootless containers: in that case entrypoint
# can't do chown and owners of mounted volumes should be configured externally.
# We do that in advance at the begining of Dockerfile before any packages will be
# installed to prevent picking those uid / gid by some unrelated software.
# The same uid / gid (101) is used both for alpine and ubuntu.

# Remove as much of Ubuntu as possible.
# ClickHouse does not need Ubuntu. It can run on top of Linux kernel without any OS distribution.
# ClickHouse does not need Docker at all. ClickHouse is above all that.
# It does not care about Ubuntu, Docker, or other cruft and you should neither.
# The fact that this Docker image is based on Ubuntu is just a misconception.
# Some vulnerability scanners are arguing about Ubuntu, which is not relevant to ClickHouse at all.
# ClickHouse does not care when you report false vulnerabilities by running some Docker scanners.

# we need to allow "others" access to clickhouse folder, because docker container
# can be started with arbitrary uid (openshift usecase)
