安装Jenkins

预先安装docker、docker-compose环境

拉取Jenkins镜像,运行容器:

1
docker run --name myjenkins -p 9980:8080 -p 50000:50000 -v /var/jenkins_home jenkins:2.60.3

映射端口为本地9980映射内部8080端口,50000映射50000端口。

Jenkins initial setup is required. An admin user has been created and a password generated.
Please use the following password to proceed to installation:

a8e55644a46a468497388c8f771e9923

This may also be found at: /var/jenkins_home/secrets/initialAdminPassword

如果-d后台运行,那么前台不会出现日志,此时,密码会记录再日志中,访问Jenkins:localhost:9980,发现密码提示:
