Scan Java packages manually
This quickstart shows you how to pull a container image, manually scan it with
On-Demand Scanning, and retrieve identified vulnerabilities for system and Maven
packages. To follow this quickstart you will use Cloud Shell and an example
Alpine image.

Open a Cloud Shell in your project.\n\n [Open Cloud Shell](https://console.cloud.google.com/?cloudshell=true)\n\n This opens a terminal with all the required tools to follow this guide.\n2. Use docker to pull the container image:\n\n docker pull jenkins:2.60.3-alpine\n\n3. Run the scan:\n\n gcloud artifacts docker images scan jenkins:2.60.3-alpine --additional-package-types=MAVEN\n\n This triggers that scanning process and returns the scan name when finished: \n\n ```\n ✓ Scanning container image \n ✓ Locally extracting packages and versions from local container image\n ✓ Remotely initiating analysis of packages and versions\n ✓ Waiting for analysis operation to complete [projects/my-project/locations/us/operations/1a6fd941-b997-4e5f-ba4f-6351f30e7dad]\n Done.\n\n done: true\n metadata:\n '@type': type.googleapis.com/google.cloud.ondemandscanning.v1.AnalyzePackagesMetadata\n createTime: '2021-01-26T13:43:53.112123Z'\n resourceUri: jenkins:2.60.3-alpine\n name: projects/my-project/locations/us/operations/1a6fd941-b99f-4eaf-ba4f-6e5af30e7dad\n response:\n '@type': type.googleapis.com/google.cloud.ondemandscanning.v1.AnalyzePackagesResponse\n scan: projects/my-project/locations/us/scans/893c91ce-7fe6-4f1a-a69a-d6ca1b465160\n ```\n4.
