| `CLAIR_VULNERABILITIES_DB_URL` | (**DEPRECATED - use `CLAIR_DB_CONNECTION_STRING` instead**) This variable is explicitly set in the [services section](https://gitlab.com/gitlab-org/gitlab/-/blob/898c5da43504eba87b749625da50098d345b60d6/lib/gitlab/ci/templates/Security/Container-Scanning.gitlab-ci.yml#L23) of the `Container-Scanning.gitlab-ci.yml` file and defaults to `clair-vulnerabilities-db`. This value represents the address that the [PostgreSQL server hosting the vulnerabilities definitions](https://hub.docker.com/r/arminc/clair-db) is running on and **shouldn't be changed** unless you're running the image locally as described in the [Running the standalone Container Scanning Tool](#running-the-standalone-container-scanning-tool) section. | `clair-vulnerabilities-db` |
| `CLAIR_DB_CONNECTION_STRING` | This variable represents the [connection string](https://www.postgresql.org/docs/9.3/libpq-connect.html#AEN39692) to the [PostgreSQL server hosting the vulnerabilities definitions](https://hub.docker.com/r/arminc/clair-db) database and **shouldn't be changed** unless you're running the image locally as described in the [Running the standalone Container Scanning Tool](#running-the-standalone-container-scanning-tool) section. The host value for the connection string must match the [alias](https://gitlab.com/gitlab-org/gitlab/-/blob/898c5da43504eba87b749625da50098d345b60d6/lib/gitlab/ci/templates/Security/Container-Scanning.gitlab-ci.yml#L23) value of the `Container-Scanning.gitlab-ci.yml` template file, which defaults to `clair-vulnerabilities-db`. | `postgresql://postgres:password@clair-vulnerabilities-db:5432/postgres?sslmode=disable&statement_timeout=60000` |
| `CI_APPLICATION_REPOSITORY` | Docker repository URL for the image to be scanned. | `$CI_REGISTRY_IMAGE/$CI_COMMIT_REF_SLUG` |
| `CI_APPLICATION_TAG` | Docker respository tag for the image to be scanned. | `$CI_COMMIT_SHA` |
| `CI_APPLICATION_TAG` | Docker repository tag for the image to be scanned. | `$CI_COMMIT_SHA` |
| `CLAIR_DB_IMAGE` | The Docker image name and tag for the [PostgreSQL server hosting the vulnerabilities definitions](https://hub.docker.com/r/arminc/clair-db). It can be useful to override this value with a specific version, for example, to provide a consistent set of vulnerabilities for integration testing purposes, or to refer to a locally hosted vulnerabilities database for an on-premise offline installation. | `arminc/clair-db:latest` |
| `CLAIR_DB_IMAGE_TAG` | (**DEPRECATED - use `CLAIR_DB_IMAGE` instead**) The Docker image tag for the [PostgreSQL server hosting the vulnerabilities definitions](https://hub.docker.com/r/arminc/clair-db). It can be useful to override this value with a specific version, for example, to provide a consistent set of vulnerabilities for integration testing purposes. | `latest` |
| `DOCKERFILE_PATH` | The path to the `Dockerfile` to be used for generating remediations. By default, the scanner will look for a file named `Dockerfile` in the root directory of the project, so this variable should only be configured if your `Dockerfile` is in a non-standard location, such as a subdirectory. See [Solutions for vulnerabilities](#solutions-for-vulnerabilities-auto-remediation) for more details. | `Dockerfile` |
