升级最新版Rancher|升级最新版Rancher 2.2.6 升级最新版Rancher2.2.6

前言：之前采用离线方式部署好了 Rancher 2.2.4（https://www.cnblogs.com/weavepub/p/11053099.html），这次升级到最新版本 Rancher 2.2.6。
一、同步镜像 1.1 安装docker
新启动一台虚拟主机，安装docker（不要用生产环境，免得主机上的镜像太多）

yum install -y yum-utils device-mapper-persistent-data lvm2 yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo yum install docker-ce -y systemctl restart docker systemctl enable docker systemctl status docker

1.2 下载镜像列表文件

mkdir -p /opt/rancher/upgrade2.2.6 && cd /opt/rancher/upgrade2.2.6 https://github.com/rancher/rancher/releases/tag/v2.2.6/rancher-images.txt

1.3准备镜像脚本
1）镜像下载脚本

vim rancher-save-images.sh
#内容如下：

#!/bin/bash # 定义日志 workdir=`pwd` log_file=${workdir}/sync_images_$(date +"%Y-%m-%d").loglogger() { log=$1 cur_time='['$(date +"%Y-%m-%d %H:%M:%S")']' echo ${cur_time} ${log} | tee -a ${log_file} }list="rancher-images.txt" #images="rancher-images.tar.gz"POSITIONAL=() while [[ $# -gt 0 ]]; do key="$1" case $key in -i|--images) images="$2" shift # past argument shift # past value ; ; -l|--image-list) list="$2" shift # past argument shift # past value ; ; -h|--help) help="true" shift ; ; esac doneusage () { echo "USAGE: $0 [--image-list rancher-images.txt] [--images rancher-images.tar.gz]" echo "[-l|--images-list path] text file with list of images. 1 per line." echo "[-l|--images path] tar.gz generated by docker save." echo "[-h|--help] Usage message" }if [[ $help ]]; then usage exit 0 fiset -e -xmkdir -p rancher-images-$(date +"%Y-%m-%d") cd rancher-images-$(date +"%Y-%m-%d")for i in $(cat ${list}); do docker pull ${i}if [ $? -ne 0 ]; then logger "${i} pull failed." else logger "${i} pull successfully." fidocker save ${i} | gzip > $(echo $i | sed "s#/#-#g; s#:#-#g").tgzif [ $? -ne 0 ]; then logger "${i} save failed." else logger "${i} save successfully." fi done

View Code 2）镜像上传到私有仓库脚本

vim rancher-push-images.sh #内容如下：

#!/bin/bash## 镜像上传说明 # 需要先在镜像仓库中创建 rancher 项目 # 根据实际情况更改以下私有仓库地址# 定义日志 workdir=`pwd` log_file=${workdir}/sync_images_$(date +"%Y-%m-%d").loglogger() { log=$1 cur_time='['$(date +"%Y-%m-%d %H:%M:%S")']' echo ${cur_time} ${log} | tee -a ${log_file} }images_hub() {while true; do read -p "输入镜像仓库地址(不加http/https): " registry read -p "输入镜像仓库用户名: " registry_user read -p "输入镜像仓库用户密码: " registry_password echo "您设置的仓库地址为: ${registry},用户名: ${registry_user},密码: xxx" read -p "是否确认(Y/N): " confirmif [ $confirm != Y ] && [ $confirm != y ] && [ $confirm == '' ]; then echo "输入不能为空，重新输入" else break fi done }images_hubecho "镜像仓库 $(docker login -u ${registry_user} -p ${registry_password} ${registry})"images=$(docker images -a | grep -v TAG | awk '{print $1 ":" $2}') namespace=rancherdocker_push() { for imgs in $(echo ${images}); do n=$(echo ${imgs} | awk -F"/" '{print NF-1}') #如果镜像名中没有/，那么此镜像一定是library仓库的镜像； if [ ${n} -eq 0 ]; then img_tag=${imgs} #namespace=rancher #重命名镜像 docker tag ${imgs} ${registry}/${namespace}/${img_tag} #删除原始镜像 #docker rmi ${imgs} #上传镜像 docker push ${registry}/${namespace}/${img_tag} #如果镜像名中有一个/，那么/左侧为项目名，右侧为镜像名和tag elif [ ${n} -eq 1 ]; then img_tag=$(echo ${imgs} | awk -F"/" '{print $2}') #namespace=$(echo ${imgs} | awk -F"/" '{print $1}') #重命名镜像 docker tag ${imgs} ${registry}/${namespace}/${img_tag} #删除旧镜像 #docker rmi ${imgs} #上传镜像 docker push ${registry}/${namespace}/${img_tag} #如果镜像名中有两个/， elif [ ${n} -eq 2 ]; then img_tag=$(echo ${imgs} | awk -F"/" '{print $3}') #namespace=$(echo ${imgs} | awk -F"/" '{print $2}') #重命名镜像 docker tag ${imgs} ${registry}/${namespace}/${img_tag} #删除旧镜像 #docker rmi ${imgs} #上传镜像 docker push ${registry}/${namespace}/${img_tag} else #标准镜像为四层结构，即：仓库地址/项目名/镜像名:tag,如不符合此标准，即为非有效镜像。 echo "No available images" fi done }docker_push

View Code 1.4 同步镜像
1）下载镜像

chmod +x rancher-save-images.sh ./rancher-save-images.sh --image-list /opt/rancher/upgrade2.2.6/rancher-images.txt

【升级最新版Rancher|升级最新版Rancher 2.2.6】2）上传镜像

chmod +x rancher-push-images.sh ./rancher-push-images.sh reg.nexus.wmqe.com admin *******

二、升级Rancher 2.1 下载 Rancher 2.2.6 离线包
登入到当初部署 Rancher 时的 prod-rancher-server-01 主机
1）更新本地helm repo缓存

helm repo update

2）查看Rancher 最新版本

helm search rancher NAMECHART VERSIONAPP VERSIONDESCRIPTION rancher-stable/rancher2.2.6v2.2.6Install Rancher Server to manage Kubernetes clusters acro...

3）获取Rancher Charts离线包

mkdir -p /opt/rancher/upgrade2.2.6 && cd /opt/rancher/upgrade2.2.6 helm fetch rancher-stable/rancher --version v2.2.6

2.2 升级 Rancher
1）升级Rancher
升级参数应该以安装时设置的参数为准。

tar zxvf rancher-2.2.6.tgz kubeconfig=/root/.kube/confighelm --kubeconfig=$kubeconfig upgrade rancher ./rancher \ --set hostname=rancher.wmqe.com \ --set ingress.tls.source=secret \ --set auditLog.level=3 \ --set auditLog.destination=hostPath \ --set auditLog.hostPath=/opt/rancher/auditlogs/ \ --set auditLog.maxAge=20 \ --set auditLog.maxBackups=20 \ --set auditLog.maxSize=100 \ --set rancherImage=reg.nexus.wmqe.com/rancher/rancher

2）查看pod状态

kubectl get pod -A

标红的都重新创建后，就可以成功访问Rancher主界面了。
