+# Run tests with Docker in Kubernetes
+
+We may [run tests localy](../LOCALSETUP.MD) using installed Dotnet and inside Kubernetes we may use a [prepared Docker images](https://hub.docker.com/repository/docker/codexstorage/cs-codex-dist-tests).
+
+
+Custom [entrypoint](docker-entrypoint.sh) will do the following
+ 1. Clone repository
+ 2. Switch to the specific branch - `master` by default
+ 3. Run all tests - `dotnet test`
+
+**Run with defaults**
+```bash
+docker run \
+  --rm \
+  --name cs-codex-dist-tests \
+  codexstorage/cs-codex-dist-tests:sha-686757e
+```
+
+**Just short tests**
+```bash
+docker run \
+  --rm \
+  --name cs-codex-dist-tests \
+  codexstorage/cs-codex-dist-tests:sha-686757e \
+  dotnet test Tests
+```
+
+**Custom branch**
+```bash
+docker run \
+  --rm \
+  --name cs-codex-dist-tests \
+  --env BRANCH=feature/tests \
+  codexstorage/cs-codex-dist-tests:sha-686757e
+```
+
+**Custom local config**
+```bash
+docker run \
+  --rm \
+  --name cs-codex-dist-tests \
+  --env CONFIG=/opt/Configuration.cs \
+  --env CONFIG_SHOW=true \
+  --volume $PWD/DistTestCore/Configuration.cs:/opt/Configuration.cs \
+  codexstorage/cs-codex-dist-tests:sha-686757e
+```
+
+**Local kubeconfig with custom local config**
+```bash
+docker run \
+  --rm \
+  --name cs-codex-dist-tests \
+  --env CONFIG=/opt/Configuration.cs \
+  --env CONFIG_SHOW=true \
+  --env SOURCE=https://github.com/codex-storage/cs-codex-dist-tests.git \
+  --volume $PWD/DistTestCore/Configuration.cs:/opt/Configuration.cs \
+  --volume $PWD/kubeconfig.yml:/opt/kubeconfig.yml \
