Currenly, clickhouse-server is run inside Docker in shell form and this prevents the server from handling SIGINT and SIGTERM signals sent, for example, by
docker stop. Hence, Docker (or any other container orchestrator) is always forced to kill the container which may lead to data corruption.In this pull request, I aim to run
clickhouse-serverin exec form. The server will be run as PID 1 and hence will be able to handle the signals.
