When installing an addon with default parameters, a Kubernetes secret will be created containing a permanent password to log in to the Grafana web interface.
Also, when installing the addon, you can specify a temporary user password. In this case, the first login to the Grafana web interface is performed with this password, then you will be prompted to change it. To do this, change the value of the field in the addon setup code:
grafana:adminPassword: "<temporary user password>"
After editing the addon code continue installing the addon.
This operation is available if the monitoring addon kube-prometheus-stack is installed in the cluster.
The Prometheus disk stores cluster monitoring data. If there is not enough space for them, or you want to increase the performance of the Prometheus disk, increase the disk size.
