Lab 13.3. Adding Tools for Monitoring and Metrics
Hello,
After fetching the chart, i don't see anything relating to service in my values.yaml
Here the result of the grep on the values.yaml
harimino@cp-node:~/kubernetes-dashboard$ cat values.yaml | grep service serviceMonitor:
Or I should do the change on one of those file
charts/metrics-server/values.yaml
charts/ingress-nginx/values.yaml ==> I have the type here
charts/cert-manager/values.yaml

Hi @harimino,
It seems the
values.yaml
of the latestkubernetes-dashboard
charts no longer include the service configuration.As a workaround, you can deploy the
dashboard
release of thekubernetes-dashboard
chart, and edit the service object to update its type and, optionally, declare a desired nodeport value:kubectl edit service dashboard-kubernetes-dashboard

Hello @chrispokorni good night!
I tried installing the dashboard charm.
helm upgrade --install metrics-server metrics-server/metrics-server
root@masternode:~# helm repo add metrics-server https://kubernetes-sigs.github.io/metrics-server/
"metrics-server" has been added to your repositories
root@masternode:~# helm upgrade --install metrics-server metrics-server/metrics-server
Release "metrics-server" does not exist. Installing it now.

In the installation output itself it says that there are properties that need to be defined, in this case should I go to the home/.cache/helm/repository directory and change its yaml so that I can create the correct resources?

Hi @marcossantos,
It seems you are using an alternative method to install the metrics-server, which has not been tested in the course lab environment.
Please use the installation approach presented in the lab guide with the additional tweaks posted in earlier forum posts.
Install the latest release of the metrics-server from its github repo as presented in step 3, then in step 5 edit the deployment with the flags recommended in this earlier comment.
Once metrics-server is up and running, install the dashboard chart as instructed in the lab guide, and read through the following comments for suggested edits:
