# Docker Containers for Testing > **Note** For production containers please visit: . This directory hosts docker files for testing cp2k. They are mostly used by the [cp2k-ci](https://github.com/cp2k/cp2k-ci) to check pull requests and populate the [dashboard](https://dashboard.cp2k.org). To run a test one simply has to build the image: ```shell ./spack_cache_start.sh podman build --network=cp2k-spack-cache-net --shm-size=1g -f Dockerfile.test_sdbg -t cp2k_test_sdbg ../../ ``` To retrieve the cached report of an old image simply run it: ```shell podman run cp2k_test_sdbg ```
