Resolution

Steps to verify whether "chartmuseum" installed along with Harbor or not:

Method 1:

• Open Harbor repository GUI
• navigate to Projects -> click on any Project -> within that if you see 'Helm Charts' tab -> which means "chartmuseum" is present.
• 

Method 2:

• Connect to Harbor VM through SSH
• run a command:

  • curl -k -X GET https://HARBOR-FQDN-IP/api/v2.0/systeminfo -u HARBOR-USER:HARBOR-PWD

  • HARBOR-USER - Harbor username
    HARBOR-PWD - Harbor Password
• The output will be similar to below one:

  • {
      "auth_mode": "db_auth",
      "current_time": "2024-12-09T08:40:44.173Z",
      "external_url": "https://Harbor-FQDN.com",
      "harbor_version": "v2.6.3-1297af6c",
      "has_ca_root": false,
      "notification_enable": true,
      "project_creation_restriction": "everyone",
      "read_only": false,
      "registry_storage_provider_name": "filesystem",
      "registry_url": "Harbor-FQDN.com",
      "self_registration": false,
      "with_chartmuseum": true,
      "with_notary": false
    }

  • In the output if the ""with_chartmuseum": true" is true, then Chartmuseum is installed along with Harbor, if the value is "with_chartmuseum": false", then Chartmuseum is not installed along with Harbor.

If chartmuseum is not installed, Manually install by following below steps:

• Goto Harbor Virtual Machine
• navigate to /home/vmware/harbor-2.7.3/harbor/
• run command:

  • ./prepare && ./install.sh --with-chartmuseum
