#執行jenkins

[root@localhost develop]# docker run --name jenkins -d -p 9003:8080 -p 9004:50000 -v /home/develop/jenkins/:/var/jenkins_home jenkins/jenkins:latest

解決方法

vim /etc/sysctl.conf

新增如下程式碼： net.ipv4.ip_forward=1

重啟network服務 systemctl restart network

檢視是否修改成功 sysctl net.ipv4.ip_forward

[root@localhost develop]# docker run --name jenkins -d -p 9003:8080 -p 9004:50000 -v /home/develop/jenkins/:/var/jenkins_home jenkins/jenkins:latest
