Could you show me the steps of your operation and the version of your environment

[AndyEWang]

same in the latest image openyurt/yurt-app-manager:latest I found the secret is empty in config/setup/all_in_one.yaml

      volumes:
      - name: cert
        secret:
          defaultMode: 420
          secretName: yurt-app-manager

# Source: yurt-app-manager/templates/secret.yaml
apiVersion: v1
kind: Secret
metadata:
  name: yurt-app-manager
  namespace: kube-system

So we need to manually add the cert firstly, right?

[rambohe-ch]

@huiwq1990 I think we need to update config/setup/all_in_one.yaml file in terms of helm charts of yurt-app-manager. would you be able to upgrade yaml file of yurt-app-manager?

@huiwq1990 I think we need to update config/setup/all_in_one.yaml file in terms of helm charts of yurt-app-manager. would you be able to upgrade yaml file of yurt-app-manager?

@rambohe-ch I will do the follow things:

1) recover the all-in-one.yaml to the old version, make sure the document instruction is fine, but the yurt-app-manager version is old; 2) modify the document, recommend user to use helm install yurt-app-manager; 3) deprecated the all-in-one.yaml;

[rambohe-ch]

@beatyman The problem has been solved by #101 . please you can take a try with the newest all_in_one.yaml, and i will close this issue at first.
