## Custom Workload View
1060+
1061+
You can customize the workload view with CRDs or any resources you want to see on this view.
1062+
1063+
To do so, you will need to update your config to add a new field `workloadGVRs` following this pattern:
1064+
```
1065+
k9s:
1066+
workloadGVRs:
1067+
- name: "v1/pods"
1068+
- name: "test.com/v1alpha1/myCRD"
1069+
status:
1070+
cellName: "State"
1071+
readiness:
1072+
cellName: "Current"
1073+
# The cellExtraName will be added as `cellName/cellExtraName`
1074+
cellExtraName: "Desired"
1075+
validity:
1076+
replicas:
1077+
cellCurrentName: "Current"
1078+
cellDesiredName: "Desired"
1079+
matchs:
1080+
- cellName: "State"
1081+
cellValue: "Ready"
1082+
- name: "external-secrets.io/v1beta1/externalsecrets"
1083+
status:
1084+
na: true
1085+
validity:
1086+
matchs:
1087+
- cellName: Ready
1088+
cellValue: True
1089+
- cellName: Status
1090+
cellValue: SecretSynced
1091+
```
1092+
The first one (`v1/pods`) will be recognized by k9s and will set it's default values for the readiness, validity and status.
1093+
1094+
The second one (`test.com/v1alpha1/myCRD`) will be an unknown GVR, it will use this configuration to be shown on the workload view.
1095+
1096+
The third one (`external-secrets.io/v1beta1/externalsecrets`) will be an unknown GVR, it will use this configuration to be shown on the workload view, but as the readiness is not set, it will use the default values it. About the status, it's set as `na: true` not applicable (for example the secrets does not need a status).
1097+
1098+
The default values applied for an unknown GVR are if they are not set and if they are not flagged as not applicable are:
1099+
```
1100+
status:
1101+
cellName: "Status"
1102+
validity:
1103+
matchs:
1104+
- cellName: "Ready"
1105+
cellValue: "True"
1106+
readiness:
1107+
cellName: "Ready"
1108+
```
1109+
1110+
The known GVRs from k9s are:
1111+
```
1112+
- v1/pods
1113+
- apps/v1/replicasets
1114+
- v1/serviceaccounts
1115+
- v1/persistentvolumeclaims
1116+
- scheduling.k8s.io/v1/priorityclasses
1117+
- v1/configmaps
1118+
- v1/secrets
1119+
- v1/services
1120+
- apps/v1/daemonsets
1121+
- apps/v1/statefulSets
1122+
```
1123+
1124+
The full structure about the configuration is:
1125+
```
1126+
workloadGVRs:
1127+
