GitLab CI

If you're a GitLab Ultimate customer, GitLab 14.0 and above include out-of-the-box integration with Trivy. To enable it for your project, simply add the container scanning template to your .gitlab-ci.yml file. For more details, please refer to GitLab's documentation.

If you're using an earlier version of GitLab, you can still use the new integration by copying the contents of the 14.0 template to your configuration.

Alternatively, you can always use the example configurations below.

Example Repository

GitLab CI using Trivy container

To scan a previously built image that has already been pushed into the GitLab container registry the following CI job manifest can be used. Note that entrypoint needs to be unset for the script section to work. In case of a non-public GitLab project Trivy additionally needs to authenticate to the registry to be able to pull your application image. Finally, it is not necessary to clone the project repo as we only work with the container image.

container_scanning:
  image:
    name: docker.io/aquasec/trivy:latest
    entrypoint: [""]
  variables:
    # No need to clone the repo, we exclusively work on artifacts.  See
    # https://docs.gitlab.com/ee/ci/runners/README.html#git-strategy

    TRIVY_CACHE_DIR: ".trivycache/"
    FULL_IMAGE_NAME: $CI_REGISTRY_IMAGE:$CI_COMMIT_REF_SLUG
  script:
    - trivy --version
    # cache cleanup is needed when scanning images with the same tags, it does not remove the database
    - time trivy image --clear-cache
    # update vulnerabilities db
    - time trivy image --download-db-only
    # Builds report and puts it in the default workdir $CI_PROJECT_DIR, so `artifacts:` can take it from there
    - time trivy image --exit-code 0 --format template --template "@/contrib/gitlab.tpl"
        --output "$CI_PROJECT_DIR/gl-container-scanning-report.json" "$FULL_IMAGE_NAME"
    # Prints full report

Gitlab CI alternative template

Depending on the edition of gitlab you have or your desired workflow, the container scanning template may not meet your needs. As an addition to the above container scanning template, a template for code climate has been included. The key things to update from the above examples are the template and report type. An updated example is below.

stages:
  - test

trivy:
  stage: test
  image: docker:stable
  services:
    - name: docker:dind
      entrypoint: ["env", "-u", "DOCKER_HOST"]
      command: ["dockerd-entrypoint.sh"]
  variables:
    DOCKER_HOST: tcp://docker:2375/
    DOCKER_DRIVER: overlay2
    # See https://github.com/docker-library/docker/pull/166
    DOCKER_TLS_CERTDIR: ""
    IMAGE: trivy-ci-test:$CI_COMMIT_SHA
    TRIVY_NO_PROGRESS: "true"
    TRIVY_CACHE_DIR: ".trivycache/"
  before_script:
    - export TRIVY_VERSION=$(wget -qO - "https://api.github.com/repos/aquasecurity/trivy/releases/latest" | grep '"tag_name":' | sed -E 's/.*"v([^"]+)".*/\1/')
    - echo $TRIVY_VERSION
    - wget --no-verbose https://github.com/aquasecurity/trivy/releases/download/v${TRIVY_VERSION}/trivy_${TRIVY_VERSION}_Linux-64bit.tar.gz -O - | tar -zxvf -
  allow_failure: true
  script:
    # Build image
    - docker build -t $IMAGE .
    # Build report
    - ./trivy image --exit-code 0 --format template --template "@contrib/gitlab-codequality.tpl" -o gl-codeclimate.json $IMAGE
  cache:
    paths:
      - .trivycache/
  # Enables https://docs.gitlab.com/ee/user/application_security/container_scanning/ (Container Scanning report is available on GitLab EE Ultimate or GitLab.com Gold)
  artifacts:
    paths:
      - gl-codeclimate.json
    reports:
      codequality: gl-codeclimate.json

Currently gitlab only supports a single code quality report. There is an open feature request to support multiple reports. Until this has been implemented, if you already have a code quality report in your pipeline, you can use jq to combine reports. Depending on how you name your artifacts, it may be necessary to rename the artifact if you want to reuse the name. To then combine the previous artifact with the output of trivy, the following jq command can be used, jq -s 'add' prev-codeclimate.json trivy-codeclimate.json > gl-codeclimate.json.
