软件开发最初是由两个团队共同组成:(没有采用DevOps之前)
没有采用DevOps的缺点:
采用DevOps的优点?
整体的软件开发流程:
为了保证整体流程可以高效的完成,各个阶段都有比较常见的工具,如下图:
Code阶段步骤:
在Windows环境下编写好代码,然后将代码上传到Linux环境下的GitLab上。
步骤:
1:新建一个服务器(2核4G内存+60G硬盘),IP设置成192.168.184.70,主机名设置成centos7-gitlab,专门用来运行GitLab。
2:安装Docker容器。(如果已经安装过了就可以跳过这一步)
3:在这台新的GitLab的服务器上使用Docker的方式运行GitLab。
创建新的虚拟机过程省略!!!
vi /etc/sysconfig/network-scripts/ifcfg-ens33
找到 IPADDR 字段并将IP修改成192.168.184.70即可:
然后重启网络:
systemctl restart network
查看IP是否修改成功:(可以看到ens33已经修改成功了。)

配置镜像加速器方法。
针对Docker客户端版本大于 1.10.0 的用户,可以通过修改daemon配置文件/etc/docker/daemon.json来使用加速器
mkdir -p /etc/docker
cat <<EOF> /etc/docker/daemon.json
{
"exec-opts": ["native.cgroupdriver=systemd"],
"registry-mirrors": [
"https://u01jo9qv.mirror.aliyuncs.com",
"https://hub-mirror.c.163.com",
"https://mirror.baidubce.com"
],
"live-restore": true,
"log-driver":"json-file",
"log-opts": {"max-size":"500m", "max-file":"3"},
"max-concurrent-downloads": 10,
"max-concurrent-uploads": 5,
"storage-driver": "overlay2"
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
最后就接入阿里云容器镜像加速器成功啦。
