k8s的CICD实施项目

weixin_438068462025-01-20 10:28

环境需求：

目前领导需要做一个需求，临时把我从运维岗位，把我调度到到专家组让我主导cicd的项目实施

目前环境资源

k8s环境，28台服务器，上面是k8s集群，要实施一个测试环境的cicd以及一个生产环境的cicd

gitlab代码服务器

jenkins服务器

镜像仓库采用的是ACR仓库

一、部署jenkins服务器

cpp 复制代码 
docker run -d --name=jenkins --restart=always -e  \
JENKINS_PASSWORD=admin123 -e JENKINS_USERNAME=admin -e   \
JENKINS_HTTP_PORT_NUMBER=8080 -p 8080:8080 -p 50000:50000 -v   \
/data/jenkins_data:/bitnami/jenkins   bitnami/jenkins :2.479.2-debian-12-r0

访问的时候用

http://192.168.8.9:9090

输入账号密码 admin/admin123 进行访问

按照对应的插件

cpp 复制代码 
在这里插入代码片

二、部署gitlab服务器

gitlab相关的软件包在清华源可以找到

cpp 复制代码 
yum -y install gitlab-ce

三、部署harbor的镜像仓库

jenkinsfile不带审批功能
