Helm安装Mysql8主从复制集群
目录
一、Helm安装
这里不再赘叙，具体安装请参考官网
二、安装mysql
1、拉取镜像
#添加仓库
helm repo add bitnami https://charts.bitnami.com/bitnami
#搜索镜像
helm search repo mysql
#拉取镜像
helm pull bitnami/mysql --version 12.0.0
#加压文件
tar -zxf mysql-12.0.0.tgz
2、修改配置文件

## Mysqld Prometheus exporter resource requests and limits
## ref: https://kubernetes.io/docs/concepts/configuration/manage-compute-resources-container/
## We usually recommend not to specify default resources and to leave this as a conscious
## choice for the user. This also increases chances charts run on environments with little
## resources, such as Minikube. If you do want to specify resources, uncomment the following
## lines, adjust them as necessary, and remove the curly braces after 'resources:'.
## @param metrics.resourcesPreset Set container resources according to one common preset (allowed values: none, nano, micro, small, medium, large, xlarge, 2xlarge). This is ignored if metrics.resources is set (metrics.resources is recommended for production).
## More information: https://github.com/bitnami/charts/blob/main/bitnami/common/templates/_resources.tpl#L15
##
resourcesPreset: "nano"
## @param metrics.resources Set container requests and limits for different resources like CPU or memory (essential for production workloads)
## Example:
## resources:
## requests:
## cpu: 2
## memory: 512Mi
## limits:
## cpu: 3
## memory: 1024Mi
##
resources: {}

## Mysqld Prometheus exporter readiness probe
## ref: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle/#container-probes
## @param metrics.readinessProbe.enabled Enable readinessProbe
## @param metrics.readinessProbe.initialDelaySeconds Initial delay seconds for readinessProbe
## @param metrics.readinessProbe.periodSeconds Period seconds for readinessProbe

3、创建mysql-secret
apiVersion: v1
kind: Secret
metadata:
name: mysql-secret
namespace: mysql8
labels:
app: mysql
type: Opaque
data:
password: MTIzNDU2 # echo -n "123456"
mysql-root-password: MTIzNDU2
mysql-replication-password: MTIzNDU2
4、安装
#创建ns
kubectl create ns mysql8
#创建secret
kubectl create -f mysql-secret.yaml
#安装mysql8
helm install mysql ./mysql -n mysql8
#查看资源
kubectl get all -n mysql8
