    include:
      - template: Container-Scanning.gitlab-ci.yml
 
    container_scanning:
-     image: your.local.registry:5000/gitlab-klar-analyzer

+       CLAIR_DB_IMAGE: $CI_REGISTRY/namespace/clair-vulnerabilities-db
    ```
 
+It may be worthwhile to set up a [scheduled pipeline](../../project/pipelines/schedules.md) to automatically build a new version of the vulnerabilities database on a preset schedule.  You can use the following `.gitlab-yml.ci` as a template:
+
+```yaml
+image: docker:stable
+
+services:
+  - docker:stable-dind
+
+stages:
+  - build
+
+build_latest_vulnerabilities:
+  stage: build
+  script:
+    - docker pull arminc/clair-db:latest
+    - docker tag arminc/clair-db:latest $CI_REGISTRY/namespace/clair-vulnerabilities-db
+    - docker login -u gitlab-ci-token -p $CI_JOB_TOKEN $CI_REGISTRY
+    - docker push $CI_REGISTRY/namespace/clair-vulnerabilities-db
+```
+
+The above template will work for a GitLab Docker registry running on a local installation, however, if you're using a non-GitLab Docker registry, you'll need to change the `$CI_REGISTRY` value and the `docker login` credentials to match the details of your local registry.

+### Running functions locally
+
+Running a function locally is a good way to quickly verify behavior during development.
+
+Running functions locally requires:
+
+- Go 1.12 or newer installed.
+- Docker Engine installed and running.
+- `gitlabktl` installed using the Go package manager:
+  
+  ```shell
+  GO111MODULE=on go get gitlab.com/gitlab-org/gitlabktl
+  ```
+
+To run a function locally:
+
+1. Navigate to the root of your GitLab serverless project.
+1. Build your function into a Docker image:
+
+   ```shell
+   gitlabktl serverless build
+   ```
+
+1. Run your function in Docker:
+
+   ```shell
+   docker run -itp 8080:8080 <your_function_name>
+   ```
+
+1. Invoke your function:
+
+   ```shell
+   curl http://localhost:8080
+   ```
+
