Longhorn 分布式存储

version: 1.6.2

• 默认会使用所有可用节点的空间

• 默认会部署相关组件到所有可用节点上

• 这里我们采用 指定节点只做存储，不允许不相关的 Pod 调度

运行节点

专门 3 台服务器，做数据存储

打上标签和污点，node选择器、容忍度

kubectl taint nodes <node> Longhorn=true:NoSchedule
kubectl label nodes <node> node.longhorn.io/create-default-disk=true

安装依赖

所有节点

yum install -y iscsi-initiator-utils nfs-utils jq

节点检查

# 节点检查需要存在找个临时目录
mkdir /tmp/longhorn-environment-check 
mkdir /var/lib/longhorn/engine-binaries/longhornio-longhorn-engine-v1.6.2 -p
mkdir /var/lib/longhorn/unix-domain-socket/ -p

curl -sSfL https://raw.githubusercontent.com/longhorn/longhorn/v1.2.3/scripts/environment_check.sh | bash

设置仓库

helm repo add longhorn https://charts.longhorn.io
helm repo update

安装版本

values.yaml 配置修改, 在本文最下方

helm pull longhorn/longhorn --version 1.6.2
helm install longhorn longhorn/longhorn --namespace longhorn-system --create-namespace --version 1.6.2 -f longhorn/values.yaml 
kubectl -n longhorn-system get pod

  ## If tls is set to true, annotation ingress.kubernetes.io/secure-backends: "true" will automatically be set
  # -- Ingress annotations in the form of key-value pairs.
  annotations:
  #  kubernetes.io/ingress.class: nginx
  #  kubernetes.io/tls-acme: true

  # -- Secret that contains a TLS private key and certificate. Use secrets if you want to use your own certificates to secure ingresses.
  secrets:
  ## If you're providing your own certificates, please use this to add the certificates as secrets
  ## key and certificate should start with -----BEGIN CERTIFICATE----- or
  ## -----BEGIN RSA PRIVATE KEY-----
  ##
  ## name should line up with a tlsSecret set further up
  ## If you're using kube-lego, this is unneeded, as it will create the secret for you if it is not set
  ##
  ## It is also possible to create and manage the certificates outside of this helm chart
  ## Please see README.md for more information
