Allow to build ClickHouse in Docker for different platforms with different compilers and build settings. Correctly configured Docker daemon is single dependency. Usage: Build deb package with `clang-11` in `debug` mode: ``` $ mkdir deb/test_output $ ./packager --output-dir deb/test_output/ --package-type deb --compiler=clang-11 --build-type=debug $ ls -l deb/test_output -rw-r--r-- 1 root root 3730 clickhouse-client_18.14.2+debug_all.deb -rw-r--r-- 1 root root 84221888 clickhouse-common-static_18.14.2+debug_amd64.deb -rw-r--r-- 1 root root 255967314 clickhouse-common-static-dbg_18.14.2+debug_amd64.deb -rw-r--r-- 1 root root 14940 clickhouse-server_18.14.2+debug_all.deb -rw-r--r-- 1 root root 340206010 clickhouse-server-base_18.14.2+debug_amd64.deb -rw-r--r-- 1 root root 7900 clickhouse-server-common_18.14.2+debug_all.deb ``` Build ClickHouse binary with `clang-11` and `address` sanitizer in `relwithdebuginfo` mode: ``` $ mkdir $HOME/some_clickhouse $ ./packager --output-dir=$HOME/some_clickhouse --package-type binary --compiler=clang-11 --sanitizer=address $ ls -l $HOME/some_clickhouse -rwxr-xr-x 1 root root 787061952 clickhouse lrwxrwxrwx 1 root root 10 clickhouse-benchmark -> clickhouse lrwxrwxrwx 1 root root 10 clickhouse-clang -> clickhouse lrwxrwxrwx 1 root root 10 clickhouse-client -> clickhouse lrwxrwxrwx 1 root root 10 clickhouse-compressor -> clickhouse lrwxrwxrwx 1 root root 10 clickhouse-copier -> clickhouse lrwxrwxrwx 1 root root 10 clickhouse-extract-from-config -> clickhouse lrwxrwxrwx 1 root root 10 clickhouse-format -> clickhouse lrwxrwxrwx 1 root root 10 clickhouse-lld -> clickhouse lrwxrwxrwx 1 root root 10 clickhouse-local -> clickhouse lrwxrwxrwx 1 root root 10 clickhouse-obfuscator -> clickhouse lrwxrwxrwx 1 root root 10 clickhouse-odbc-bridge -> clickhouse lrwxrwxrwx 1 root root 10 clickhouse-server -> clickhouse ```
