Docker Installation Jenkins

Installation Environment

Operating system centos7.3

Installing Docker, installation and configuration see Docker Docker Introduction and installation Configuration jenkins Download Jenkins

Command: sudo docker pull Jenkins is ready to create Jenkins folder before starting Jenkins

Create a Jenkins folder for disk-mounted and in-container folders

Command: Mkdir/home/hzq/jenkins

Note: When you install Jenkins, the attribution user ID that hangs in the folder/home/hzq/jenkins/must be 1000, otherwise the no-action permission exception will be thrown. Exceptions are as follows:

why the attribution user ID for a folder must be 1000.

For the first time I contacted Jenkins, it was really depressing. Why the UID must be 1000. With a question I went to see the dockerfile provided in the Docker Central warehouse, where I saw the following code:

View folder's Attribution

Command: Ls-nd folder name

to modify the ownership and group of folders

Command: sudo chown-r 1000:1000 jenkins/ start Jenkins start Jenkins

Command:

sudo docker run-itd-p 8080:8080-p 50000:50000--name Jenkins--privileged=true  -v/home/hzq/jenkins:/var/jenkins_h Ome Jenkins

-P 8080:8080-p 50,000:50,000 for port mapping

--privileged=true in CentOS7 the security module SELinux has restricted the permissions, the parameters to the container plus privileges.

-v/home/hzq/jenkins:/var/jenkins_home Disk Mount view run status

Command: sudo Dockers PS

first use of Jenkins 1. Get the Administrator password:

Enter Jenkins in the browser input "localhost:8080", the first entry needs to get the administrator's password, as shown in figure:

Get Password method one:

When Jenkins starts, we set the folder to hang, so we can view the password directly in the local Jenkins directory:

Get Password Method two:

Get password when not hanging on disk

Command: sudo docker exec Jenkins Cat/var/jenkins_home/secrets/initialadminpassword

There is actually another way to get inside the container using the Attach command, and then look at the password. This way of operation is too cumbersome, not explained here.
Through the above method, get to the password and enter Jenkins. 2, configure the network agent (do not need to go online through the agent Skip)

Because the personal network needs to configure the agent to surf the internet, so this belongs to the offline status, click on the "Confirure proxy" setting agent.

3, install the plug-in

You can customize the installation plug-in, or you can install the recommended plugins.

To start the installation:
4. Create User

5. Complete
