Map MID Server to container image repository

If network access or datacenter location requires a specific MID Server, map MID Server to a private container image repository.

Avant de commencer

• Verify that you have at least version 1.30.0 of Discovery and Service Mapping Patterns.
• Verify that the Linux MID Server has the following requirements:
  • 8GB RAM with 4GB for the Java Virtual Machine (JVM).
  • MID Server Capability configured to Scan Container Images. For more information on configuring capabilities, see MID Server capabilities.
  • Can access the image repository.
  • Has Aqua Trivy, starting 0.44.0, installed on the MID Server. The last version validated is 0.68.2. For more information on installing Aqua Trivy, see the Container Image scan feature overview [KB1218504] article in the Now Support Knowledge Base.
• Verify that the container image repository credentials are configured for the private repositories. For more information, see Create and test your credentials and Container image repository credentials.
• Verify that a container image discovery has run for Docker, Kubernetes, or Amazon Elastic Container Service (Amazon ECS) discovery. For more information, see:
  • Docker virtualization
  • Kubernetes discovery using patterns
  • Amazon ECS resource discovery with Patterns
• Verify that the Container Repository table contains the repository names required for this mapping. You can view the container repository list by entering cmdb_ci_container_repository_list.do in the navigation filter.
