How to implement Grafana HA and how to use --web.external-url on Grafana

[gnnx0425]

Grafana version: 7.5.2

1. We are going to implement Grafana HA in k8s. So if we deploy 2 replicas and with a NFS volume mount to both instances, is it a valid HA solution?
2. We have deployed nginx in our enviroment, but if we add args “–web.external-url”, we got the following error:
   kubectl logs grafana-78b4458bf5-b8h4d -n monitoring
   flag provided but not defined: --web.external-url
   Usage of grafana-server:
   -config string
   path to config file
   -homepath string
   path to grafana install/home path, defaults to working directory
   -packaging string
   describes the way Grafana was installed (default “unknown”)
   -pidfile string
   path to pid file
   -profile
   Turn on pprof profiling
   -profile-port uint
   Define custom port for profiling (default 6060)
   -tracing
   Turn on tracing
   -tracing-file string
   Define tracing output file (default “trace.out”)
   -v prints current version and exits

Hi @gnnx0425,

I would probably start with this documentation:

Set up Grafana for high availability
