## Running the standalone Container Scanning Tool
It's possible to run the [GitLab Container Scanning Tool](https://gitlab.com/gitlab-org/security-products/analyzers/klar)
against a Docker container without needing to run it within the context of a CI job. To scan an
image directly, follow these steps:
1. Run [Docker Desktop](https://www.docker.com/products/docker-desktop) or [Docker Machine](https://github.com/docker/machine).
1. Run the latest [prefilled vulnerabilities database](https://cloud.docker.com/repository/docker/arminc/clair-db) Docker image:
```shell
docker run -p 5432:5432 -d --name clair-db arminc/clair-db:latest
```
1. Configure an environment variable to point to your local machine's IP address (or insert your IP address instead of the `LOCAL_MACHINE_IP_ADDRESS` variable in the `CLAIR_DB_CONNECTION_STRING` in the next step):
```shell
export LOCAL_MACHINE_IP_ADDRESS=your.local.ip.address
```
1. Run the analyzer's Docker image, passing the image and tag you want to analyze in the `CI_APPLICATION_REPOSITORY` and `CI_APPLICATION_TAG` environment variables:
```shell
docker run \
--interactive --rm \
--volume "$PWD":/tmp/app \
-e CI_PROJECT_DIR=/tmp/app \
-e CLAIR_DB_CONNECTION_STRING="postgresql://postgres:password@${LOCAL_MACHINE_IP_ADDRESS}:5432/postgres?sslmode=disable&statement_timeout=60000" \
-e CI_APPLICATION_REPOSITORY=registry.gitlab.com/gitlab-org/security-products/dast/webgoat-8.0@sha256 \
-e CI_APPLICATION_TAG=bc09fe2e0721dfaeee79364115aeedf2174cce0947b9ae5fe7c33312ee019a4e \
registry.gitlab.com/gitlab-org/security-products/analyzers/klar
```
The results are stored in `gl-container-scanning-report.json`.
