Question

• What do you want to know?
  When I deploy skywalkng-swck followed by the instruction, the controller fails to start. I want to know how to solve it.

Here is the logs.

$ kubectl logs -f skywalking-swck-controller-manager-7ff8f456c4-f4m79 manager -n skywalking-swck-system
container_linux.go:235: starting container process caused "exec: \"/manager\": stat /manager: no such file or directory"

---

Bug

• Which version of SkyWalking, OS, and JRE?
  Skywalking Cloud on Kubernetes 0.1.0. I don't change anything.
  Kubernetes Version: 0.19.2

• Which company or project?
  Personal project.

• What happened?
  If possible, provide a way to reproduce the error. e.g. demo application, component version.

Hi @LeBW can you provide the image currently using? Use the following command

kubectl get deployment skywalking-swck-controller-manager -n skywalking-swck-system -o yaml

Hi @arugal The two images are docker.io/kubesphere/kube-rbac-proxy:v0.4.1 and apache/skywalking-swck:0.1.0.

BTW, here is the whole log if it helps.

@LeBW Look like a bug, this can be fixed with the following command:
kubectl patch deployment.apps/skywalking-swck-controller-manager -p='{"spec": {"template": {"spec": {"containers": [{"name": "manager", "command": ["/bin/manager"]}]}}}}' -n skywalking-swck-system

@hanahmily In version 0.1.0, command does not match the path in the image, please confirm :)

[LeBW]

@arugal Fixed. Thank u :)
