Application Commands and Helm Overrides

Use system application and system helm-override commands to manage containerized applications provided as part of .

Note

Application commands and Helm overrides apply to user overrides only and take precedence over system overrides.

Use the following command to list all containerized applications provided as part of .

~(keystone_admin)]$ system application-list [--nowrap]

where:

nowrap: Prevents line wrapping of the output.

For example:

~(keystone_admin)]$ system application-list --nowrap

application	version	manifest name	manifest file	status	progress
cert-manager nginx-ingress-controller oidc-auth-apps platform-integ-apps rook-ceph-apps	1.0-34 1.1-35 1.0-68 1.0-52 1.0-17	cert-manager-fluxcd-manifests nginx-ingress-controller-fluxcd-manifests oidc-auth-apps-fluxcd-manifests platform-integ-apps-fluxcd-manifests rook-ceph-manifest	fluxcd-manifests fluxcd-manifests fluxcd-manifests fluxcd-manifests manifest.yaml	applied applied uploaded applied uploaded	completed completed completed completed completed

Use the following command to show details for .

~(keystone_admin)]$ system application-show <app_name>
