-Docker file naming convention: `Dockerfile.{type}.{extra tags}.{baseimage}`
-
-* __type__: test, prod ...
-* __extra tags__: sqlite, clang11 ...
-* __baseimage__: xenial, binoic, archlinux ...
-
-## Build sqlite test image
-
-__Run all docker commands in the root of the repository!__
-
-Build the docker image like this:
-```sh
-sudo docker build -t codechecker:test-sqlite-clang11-bionic --rm -f \
-docker/Dockerfile.test.sqlite.clang11.bionic .
-```
-
-Run the built image:
-```sh
-sudo docker run --rm -ti codechecker:test-sqlite-clang11-bionic
-```
-
-```sh
-sudo docker run --rm -ti codechecker:test-sqlite-clang11-bionic make venv_dev \
-pycodestyle, pakcage, test_unit, test_sqlite
-```
-
-Remove the built image:
-```sh
-sudo docker image rm -f codechecker:test-sqlite-bionic
-```
-
-# Cleanup
-
-To remove stopped containers, dangling images ...
-```sh
-sudo docker system prune
-```
