Troubleshooting

If the installation fails or never ends, here a few things to check.

Cannot execute the nuv executable on Mac OSX

On Mac, downloaded binaries from third party developerse are sometimes quarantined.

To allow execution of the nuv binary after unpacking execute:

xattr -d com.apple.quarantine nuv

Check the status of the installation

Run kubectl -n nuvolaris get po, you should see something like this:

NAME                          READY   STATUS      RESTARTS   AGE
nuvolaris-operator            1/1     Running     0          7h39m
controller-66c6b48bcb-vk6fv   1/1     Running     0          7h38m
wsk-prewarm-nodejs14          0/1     Completed   0          7h38m
wsk-prewarm-python37          0/1     Completed   0          7h38m
couchdb-0                     1/1     Running     0          7h38m
redis-0                       1/1     Running     0          7h38m
couchdb-init-dv664            0/1     Completed   0          7h38m
wsk0-48-prewarm-nodejs14      1/1     Running     0          7m28s

If you are using an Ubuntu image, use sudo microk8s kubectl instead of kubectl

Check the API host has been return properly

Run kubectl -n nuvolaris get cm/config -o yaml, you should see something like this:

apiVersion: v1
kind: ConfigMap
metadata:
  annotations:
    apihost: https://ec2-18-191-242-88.us-east-2.compute.amazonaws.com
    kubectl.kubernetes.io/last-applied-configuration: |
      {"apiVersion":"v1","kind":"ConfigMap","metadata":{"annotations":{},"name":"config","namespace":"nuvolaris"}}
  name: config
  namespace: nuvolaris

Check you have a .nuvolaris/.wskpros in your home directory

This is the file used to access to Nuvolaris.

It should look like this:

AUTH=8c059563-be75-4b39-a725-769304701a6f:CoIM5TNkbX35dTiLLJnrBb72XT7vDHSSAp1GY1PfpMkUGlSxaEnPFHNacF8HJLBn
APIHOST=http://ec2-19-181-212-78.us-east-2.compute.amazonaws.com

If there is only the operator running

Check the logs of the operator with:

kubectl -n nuvolaris logs pod/nuvolaris-operator

Then open an issue reporting the logs

Uninstall

You can uninstall Nuvolaris with:

./nuv setup --uninstall=<kubernetes-context>

Remember also to remove the ~/.nuvolaris folder from your home directory or it will retry the same parameters.
