需求描述:
公司内部的git仓库 golang 服务端代码需要以docker打包的方式发布到外网多台服务器中,作为api接口服务启动,然后nginx反向代理到这几台机器中
如果不以docker的方式启动直接编译发布启动也是可以的,以docker启动方式主要是为后续上k8s等类似的平台做技术铺垫
大概的思路:
1.jenkins拉取git代码通过rsync推送到远端服务器中
2.在远端搭建docker的仓库harbor服务器
3.通过jenkins的方式调取远端服务器中的脚本进行 doker 的打包并推送到harbor中,然后拉取harbor中的镜像启动服务
架构图
1.在远端服务器中安装docker,在其中一台服务器中安装harbor作为镜像服务器
# 安装docker
yum install -y yum-utils
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum install -y docker-ce
环境准备
mkdir -p /data/www/vhosts/docker/storage/logs
chown -R apache.users /data/www/vhosts/docker/
2.修改docker配置(每个服务端的ip端最好不同)
mkdir /etc/docker
# vim /etc/docker/daemon.json
{
"graph": "/data/docker",
"storage-driver": "overlay2",
"insecure-registries": ["registry.access.redhat.com","quay.io","172.30.0.122:1800"],
"registry-mirrors": ["https://q2gr04ke.mirror.aliyuncs.com"],
"bip": "10.30.136.1/24",
"exec-opts": ["native.cgroupdriver=systemd"],
"live-restore": true
}
"bip": "10.30.162.1/24" 说明:
最好不要和公司内部或者vpc的网段冲突
服务器IP:1.2.17.136/172.30.0.70
对应
10.30.136.1/24
# 启动docker
systemctl start docker
systemctl enable docker
# 安装 harbor 仓库
参考:https://www.cnblogs.com/reblue520/p/13615972.html
修改harbor仓库的地址
hostname: 172.30.0.122
port: 1800
harbor_admin_password: pass
# 远程需要部署docker 安装包api接口的服务器上 通过apache用户登录docker harbor
# 生成config.json 这个秘钥文件,这样就可以在远程服务器中执行 pull push 命令而不需要输入账号密码直接执行了
# more /data/www/.docker/config.json
{
"auths": {
"172.30.0.122:1800": {
"auth": "efadYXJib3IyMDIxYWd2W4="
}
}
}
3.将apache用户添加可以运行docker的权限
sudo usermod -aG docker apache
4.编写远程脚本脚本
mkdir /usr/local/worksh/jeninks_task/
# cat /usr/local/worksh/jeninks_task/vidiar_search_docker_build_restart.sh
#!/bin/bash
ENV=$1
TAG=$2
# 复制环境变量
cd /data/www/vhosts/vidair-search.chinasoft.com/httpdocs
cp .env.$ENV .env
# 执行权限
chmod 755 vidair-search.exe
# 生成docker image
cd /data/www/vhosts/vidair-search.chinasoft.com/httpdocs
docker build -t 172.30.0.122:1800/todd/vidair-search:$TAG .
# 推送到docker仓库
cd /data/www/vhosts/vidair-search.chinasoft.com/httpdocs
docker push 172.30.0.122:1800/todd/vidair-search:$TAG
# 通知远程机器重新拉取image并且启动container
docker pull 172.30.0.122:1800/todd/vidair-search:${TAG}
docker stop vidair-search
docker rm -f vidair-search
docker container run -p 3012:3001 -it -d -v /data/www/vhosts/docker/storage/logs:/app/storage/logs -v /nasplatform:/nasplatform -v /nasuser:/nasuser -v /tmpdata:/tmpdata --name=vidair-search 172.30.0.122:1800/todd/vidair-search:${TAG}
# 添加可执行权限
chmod +x /usr/local/worksh/jeninks_task/vidiar_search_docker_build_restart.sh
chown -R apache.users /usr/local/worksh/jeninks_task
# Dockerfile
# more Dockerfile
From centos
RUN mkdir -p /app/storage/logs
WORKDIR /app
COPY vidair-search.exe /app/vidair-search.exe
COPY .env /app/.env
EXPOSE 3001
CMD ["/app/vidair-search.exe"]
# 修改 Dockerfile 这样可以在不能启动 docker 容器成功的情况下进入容器中排查问题
# more Dockerfile
From centos
RUN mkdir -p /app/storage/logs
WORKDIR /app
COPY vidair-search.exe /app/vidair-search.exe
COPY .env /app/.env
EXPOSE 3001
# CMD ["/app/vidair-search.exe"]
CMD ["/bin/bash","-c","tail -f /dev/null"]
5.配置jenkins发布环境
git仓库相关配置
jekins shell脚本
#!/bin/bash
# 此脚本功能为根据构建时选择的参数,同步 /data/www/vhosts/vidair-search.chinasoft.com.prod 下的文件同步到远程中转机器
# 2021.05.21 初始化脚本
#非apache用户运行脚本,则退出
if [ `whoami` != "apache" ];then
echo "only apache can run me"
exit 1
fi
echo "xxx"
## 1.定义变量
dir_name=bak.$(date +%Y-%m-%d-%H-%M-%S)
project_dir=/data/www/vhosts/vidair-search.chinasoft.com.prod
## 2.备份代码函数
function func_project_backup(){
cp -a $project_dir/ /data/data_backup/vidair-search.chinasoft.com.prod_$dir_name
}
#func_project_backup
## 3.判断代码发布目录变量是否为空
if [ ! $project_dir ];then
echo "$project_dir IS NULL ,shell exit!!!!"
exit 1
fi
## 2.判断同步状态
function func_rsync_status(){
if [[ $? == 0 || $? == 23 ]];then
rsync_edit=1
else
rsync_edit=0
echo "`date` 同步到本地目标失败! "
exit 1
fi
}
## 4.同步到本地待发路径
function func_rsync_project_local(){
echo "xxxxxxxxxxxxxx同步待发目录开始xxxxxxxxxxxxxxxxxx"
cd $WORKSPACE
/usr/local/bin/rsync -vau -progress --delete --exclude='.git/' --exclude='.gitignore' --exclude='*.log' $WORKSPACE/ $project_dir/httpdocs/
func_rsync_status
echo "xxxxxxxxxxxxxx同步待发目录完成xxxxxxxxxxxxxxxxxx"
}
func_rsync_project_local
# 执行编译
cd $project_dir/httpdocs/ && chmod +x ./init.production.sh && ./init.production.sh production
chown -R apache.users $project_dir/
sleep 1
## 5.推送代码到远程中转机并发布(发布到线上)
echo "------------------------------------ rsync start prod -----------------------------------------"
chown -R apache.users $project_dir/
sleep 1
/bin/bash /usr/local/worksh/jeninks_task/online_video.vidair-search.chinasoft.com.prod.sh
echo "------------------------------------ rsync done prod -----------------------------------------"
## 7.通过插件执行远程服务器中的脚本生成docker镜像,然后推送到仓库中,最后推送到目标服务器中,并启动
涉及的 init.production.sh 脚本内容
#!/bin/bash -l
ENV=$1
# 复制环境变量
cp .env.$ENV .env
# 处理依赖
go mod tidy
go mod vendor
# 构建启动程序
GOARCH=amd64 GOOS=linux go build -ldflags "-s -w" -o vidair-search.exe main.go
# 执行权限
chmod 755 vidair-search.exe
发布代码脚本
# cat /usr/local/worksh/jeninks_task/online_video.vidair-search.chinasoft.com.prod.sh
#!/bin/bash
