microk8s kubectl E_REQUISITE_NOT_FOUND

[gnoejuan]

Describe the bug

chectl fails ✖ Verify if kubectl is installed with E_REQUISITE_NOT_FOUND

Che version

• latest
• nightly
• other: please specify

chectl/7.8.0 linux-x64 node-v10.18.1

Steps to reproduce

• Install microk8s via snap store sudo snap install microk8s --classic --channel=1.17/stable
• Install chectl as instructed on the documents bash <(curl -sL https://www.eclipse.org/che/chectl/)
• Implement workaround 1 from here microk8s.config | cat - > $HOME/.kube/config After encountering connection refused
• chectl server:start -m -p microk8s -a helm

Expected behavior

Chectl uses the microk8s.kubectl kubectl.

Runtime

• kubernetes (include output of kubectl version)
• Openshift (include output of oc version)
• minikube (include output of minikube version and kubectl version)
• minishift (include output of minishift version and oc version)
• docker-desktop + K8S (include output of docker version and kubectl version)
• [ x ] other: microk8s v1.17.2

Screenshots

Installation method

• [ x ] chectl
• che-operator
• minishift-addon
• I don't know

Environment

• my computer
  • Windows
  • [ x ] Linux
  • macOS
• Cloud
  • Amazon
  • Azure
  • GCE
  • other (please specify)
• other: please specify

Additional context

It looks like chectl uses a repository called `command-exists. Looking at the code, it looks like command-exists simply sends commands to the command line. Chectl's implementation seems to only use command-exists.

So, I looked up how to use bash-aliases in a npm script and came across this stackoverflow solution https://askubuntu.com/a/98791 and implemented it like in my .bashrc :

EDIT: This was the original. Probably led to some of my problems. Look below for the correct addition to .bashrc

kubectl(){
    minikube.kubectl "$@"
}
export -f kubectl

which still did not work

Edit: Should have been

kubectl(){
    microk8s.kubectl "$@"
}
export -f kubectl

Update: installed kubectl through snap: snap install kubectl --classic

Now I'm ran into a missing helm requirement, even though microk8s has it.

Removing the -a helm argument gives me :

✖ 🏃  Installer preflight check
→ Installer  is not supported ¯\_(ツ)_/¯

@gnoejuan

1. Install helm on machine where chectl is installed
   or
2. Use --installer=operator

[gnoejuan]

-a operator did the fix. Thank you very much!

hmmm after rebooting, i had to "reimplement workaround 1".

[gnoejuan]

In case somebody came across this thread from google:

kubectl(){
    minikube.kubectl "$@"
}
export -f kubectl

should actually be:

kubectl(){
    microk8s.kubectl "$@"
}
export -f kubectl

Not sure if I would have ran into the helm issue, but this fixed a issue where chectl was hanging on
