Helm + Grafana¶

先准备mysql存储grafana的metedata信息实战 | 基于Kubernetes使用MySQL

name	value
database	grafana
username	grafana
password	grafana

一、安装¶

helm repo add grafana https://grafana.github.io/helm-charts
helm repo update grafana
helm search repo grafana

helm show values grafana/grafana --version 6.38.1 > grafana.yaml-6.38.1-default 

# Example 
#   https://books.8ops.top/attachment/grafana/helm/grafana.yaml-6.38.1
# 

helm install grafana grafana/grafana \
    -f grafana.yaml-6.38.1 \
    -n kube-server \
    --create-namespace \
    --version 6.38.1 --debug

helm upgrade --install grafana grafana/grafana \
    -f grafana.yaml-6.38.1 \
    -n kube-server \
    --create-namespace \
    --version 6.38.1 --debug

helm -n kube-server uninstall grafana    

CREATE DATABASE `grafana` DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci;

# reset admin exec container
grafana-cli admin reset-admin-password "admin"

二、升级¶

helm show values grafana/grafana > grafana.yaml-6.38.1-default 

# Example 
#   https://books.8ops.top/attachment/grafana/helm/grafana.yaml-6.38.1
# 

helm install grafana grafana/grafana \
    -f grafana.yaml-6.38.1 \
    -n kube-server \
    --create-namespace \
    --version 6.38.1 --debug
