一，前言

上一篇，介绍了 Secret 镜像的使用；

三台服务每天大概 15 块钱的支出，用一个月也是不少钱；

闲时可以停掉，这样每天只有 4 块钱支出，剩下一大笔；

ECS 服务停机后公网 IP 会变化，所以使用到公网 IP 的地方都需要重新配置，恢复环境；

本篇，介绍 ECS 停机后重启的环境修复；

备注：只涉及到目前未知的配置，后续章节可能会新增其他配置项，全部完成之后再补充一篇熊进行说明；

二，ci-service 服务器重启问题

ci-service 服务器停机后重启：

1，导致公网 IP 变化：39.105.212.14 -> 47.94.92.122；

2，服务器重启后：docker 镜像仓库无法访问；

三，环境修复

1，启动 docker 私有镜像仓库

[root@iZ2ze7rkgit9zoa18pxu73Z ~]# cd /usr/local/nexus-3.29.0-02/bin/
[root@iZ2ze7rkgit9zoa18pxu73Z bin]# ./nexus start
WARNING: ************************************************************
WARNING: Detected execution as "root" user.  This is NOT recommended!
WARNING: ************************************************************
Starting nexus

http://47.94.92.122:8081/ 可以正常访问私有镜像仓库，登录后查看镜像正常

2，更新公网 ip

ci-service 服务器公网 IP 变化：39.105.212.14 -> 47.94.92.122；

需要更新所有使用私有库镜像的 yaml 配置文件：

1，ci-service 的 jenkins 构建脚本更新，推送镜像到私有仓库部分

修改前脚本

// 更新前
#！/bin/sh -l
npm install --registry=https://registry.npm.taobao.org
npm run build
time=$(date "+%Y%m%d%H%M%s")
docker build -t 39.105.212.14:8082/vue-project:$time .
docker login -u $DOCKER_LOGIN_USERNAME -p $DOCKER_LOGIN_PASSWORD 39.105.212.14:8082
docker push 39.105.212.14:8082/vue-project:$time

修改前，构建失败

修改后脚本

// 更新后
#！/bin/sh -l
npm install --registry=https://registry.npm.taobao.org
npm run build
time=$(date "+%Y%m%d%H%M%s")
docker build -t 47.94.92.122:8082/vue-project:$time .
docker login -u $DOCKER_LOGIN_USERNAME -p $DOCKER_LOGIN_PASSWORD 47.94.92.122:8082
docker push 47.94.92.122:8082/vue-project:$time

修改后，构建成功，配置修改为正确

2，docker 配置更新，更新私有库注册列表

// 解决 http 问题
[root@iZ2ze7rkgit9zoa18pxu73Z ~]# vi /etc/docker/daemon.json // 添加不安全的仓库地址：insecure-registries
{"insecure-registries":["47.94.92.122:8082"],"registry-mirrors": ["https://fwvjnv59.mirror.aliyuncs.com"]
}// 重启 docker
[root@iZ2ze7rkgit9zoa18pxu73Z bin]# systemctl restart docker

后面的贴过来，不测试了：

// 测试镜像推送
[root@iZ2ze7rkgit9zoa18pxu73Z ~]# docker push 39.105.212.14:8082/vue-project:2021123011191640834385

6270adb5794c: Pushing  14.13MB/55.28MB

3，更新已生成的 Sercet 中的 docker-server

涉及“私有镜像库认证”使用的 Sercet :

命令行创建的 Sercet : registry-auth
通过文件创建的 Sercet : registry-auth-file.yaml

1）命令行创建的Sercet : registry-auth

// 原始 Sercet 的创建命令
[root@k8s-master deployment]# kubectl create secret docker-registry registry-auth \--docker-username=admin \--docker-password=****** \--docker-email=admin@example.org \--docker-server=39.105.212.14:8082
secret/registry-auth created// 查询、删除、重新创建
[root@k8s-master ~]# kubectl get secret
NAME                  TYPE                                  DATA   AGE
default-token-q4qxd   kubernetes.io/service-account-token   3      12d
registry-auth         kubernetes.io/dockerconfigjson        1      4d8h
registry-auth-file    kubernetes.io/dockerconfigjson        1      4d8h
secret-opaque         Opaque                                2      4d8h
secret-opaque-flie    Opaque                                2      4d8h// 删除
[root@k8s-master ~]# kubectl delete secret registry-auth
secret "registry-auth" deleted]// 重新创建
[root@k8s-master ~]# kubectl create secret docker-registry registry-auth \--docker-username=admin \--docker-password=****** \--docker-email=admin@example.org \--docker-server=47.94.92.122:8082
secret/registry-auth created

2）registry-auth-file.yaml

// 原始 Sercet 的创建
vi registry-auth-file.yamlapiVersion: v1
kind: Secret
metadata:name: registry-auth-file
data:.dockerconfigjson: eyJhdXRocyI6eyIzOS4xMDUuMjEyLjE0OjgwODIiOnsidXNlcm5hbWUiOiJhZG1pbiIsInBhc3N3b3JkIjoiV3pAMTk4ODA4MTgiLCJlbWFpbCI6ImFkbWluQGV4YW1wbGUub3JnIiwiYXV0aCI6IllXUnRhVzQ2VjNwQU1UazRPREE0TVRnPSJ9fX0=
type: kubernetes.io/dockerconfigjson

查看 registry-auth，使用 .dockerconfigjson 更新：

// 读取
[root@k8s-master deployment]# kubectl get secret registry-auth -o yaml
apiVersion: v1
data:.dockerconfigjson: eyJhdXRocyI6eyI0Ny45NC45Mi4xMjI6ODA4MiI6eyJ1c2VybmFtZSI6ImFkbWluIiwicGFzc3dvcmQiOiJXekAxOTg4MDgxOCIsImVtYWlsIjoiYWRtaW5AZXhhbXBsZS5vcmciLCJhdXRoIjoiWVdSdGFXNDZWM3BBTVRrNE9EQTRNVGc9In19fQ==

修改后，重新生效配置，并查看 Sercet 内容完成验证；

4，更新 deployment-v4.yaml 的镜像地址

[root@k8s-master deployment]# vi deployment-v4.yamlapiVersion: apps/v1
kind: Deployment
metadata:name: v4     #修改
spec:selector:matchLabels:app: v4  #修改replicas: 1template:metadata:labels:app: v4 #修改spec: containers:- name: vue-projectimage: 47.94.92.122:8082/vue-project:2021123011191640834385   #修改ports:- containerPort: 80[root@k8s-master deployment]# kubectl apply -f deployment-v4.yaml

生效配置，进入pod验证拉取镜像时，实际访问的镜像地址：47.94.92.122 修改生效

5，本地镜像仓库列表

删除无效的老地址镜像
