Detailed tutorial on deploying Jenkins based on docker

0. When I made this document, it was around December 2019, and er2.200 was the latest version.

1. Download the image

docker pull jenkins/jenkins 

Be sure to install the latest version of Jenkins. Many plug-ins cannot be installed with the old version.

2. View detailed information of Jenkins

docker inspect jenkins:2.200 

3. Create a jenkins directory (for persistence)

mkdir /home/jenkins_home

4. Start the container

docker run -d --name Jenkins_01 -p 8081:8080 -v \

/home/jenkins_home:/home/jenkins_home jenkins:2.200 

【Note】You may encounter iptables problems:

iptables failed: iptables --wait -t nat -A DOCKER -p tcp -d 0/0 --dport 8080 -j DNAT

--to-destination 192.168.40.142:8080 ! -i br-ff45d935188b: iptables: No

chain/target/match by that name. (exit status 1)

Restart Docker

systemctl restart docker

5. Check whether the started jenkins container is healthy

docker ps | grep jenkins 

6. Web access ip:port

7. Enter the container

docker exec -it Jenkins_01 /bin/bash 

8. Follow the prompts to view the password (in the container)

cat /var/jenkins_home/secrets/initialAdminPassword
