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
[rootiZ2ze7rkgit9zoa18pxu73Z ~]# cd /usr/local/nexus-3.29.0-02/bin/
[rootiZ2ze7rkgit9zoa18pxu73Z bin]# ./nexus start
WARNING: ************************************************************
WARNING: Detected execution as root user. This is NOT recommended!
WARNING: ************************************************************
Starting nexushttp://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
1ci-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 --registryhttps://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 --registryhttps://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 2docker 配置更新更新私有库注册列表
// 解决 http 问题
[rootiZ2ze7rkgit9zoa18pxu73Z ~]# 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

// 测试镜像推送
