Application Discovery Commands

Application definitions originate from the source Git repo. These are configured in-cluster for Flux to consume. You can use common kubectl verbs to investigate status and gather log data to help determine any problem areas:

Leverage kubectl to investigate the Git repo:

CODE
```
kubectl get gitrepository -A
```
OR

CODE

kubectl describe -n <namespace> gitrepository <name>

Check status logs of the source-controller pod:

CODE

kubectl describe -n kommander-flux deploy/source-controller

OR

CODE

kubectl logs -n kommander-flux deploy/source-controller --tail -1

Verify the status of the associated Apps, ClusterApps and AppDeployments:
- CODE
```
kubectl get apps,clusterapps,appdeployments -A
```

Check the status and logs of the kommander-appmanagement pod:

CODE

kubectl describe -n kommander deploy/kommander-appmanagement

OR

CODE

kubectl logs -n kommander deploy/kommander-appmanagement --tail -1

Kustomizations -
- Check the status of all Kustomizations created by AppDeployment:
  - CODE
```
kubectl get kustomization -A
```
    OR
  - CODE
```
kubectl describe -n <namespace> kustomization <name>
```
- Check into the status and logs of the kustomize-controller pod since it manages Kustomizations in the kommander-flux Namespace.
  - CODE
```
kubectl describe -n kommander-flux deploy/kustomize-controller
```
    OR
  - CODE
```
kubectl logs -n kommander-flux deploy/kustomize-controller --tail -1
```
HelmRelease -
- HelmRelease(s) are deployed by each Kustomization and for the Application to function, these resources must be in the “Ready” state. To check:
  - CODE
```
kubectl get helmrelease -A
```
    OR
  - CODE
```
kubectl describe -n <namespace> helmrelrease <name>
```
- Each HelmRelease also consumes a HelmChart. We can ensure the status of HelmCharts with:
  - CODE
```
kubectl get helmchart -A
```
    OR
  - CODE
```
kubectl describe -n <namespace> helmchart <name>
```
- The controller that manages HelmReleases and HelmCharts is the helm-controller in the kommander-flux Namespace. It can be helpful to check into the status and logs of the helm-controller pod:
  - CODE
```
kubectl describe -n kommander-flux deploy/helm-controller
```
    OR
  - CODE
```
kubectl logs -n kommander-flux deploy/helm-controller --tail -1
```
