Docker deployment and installation steps for Jenkins

First, we need a server with Docker installed. (I have already installed this on my server)

The first step is to pull down the image

docker pull jenkins/jenkins:lts 

The second step is to create a mapping directory

# Create a mapping directory in the appropriate location mkdir -p jenkins_home
# Check directory permissions ls -nd jenkins_home
# Change the owner to administrator sudo chown -R 1000:1000 jenkins_home 

Step 3: Start Jenkins

# View docker images 

# Start Jenkins
docker run -d -p 12580:8080 --name=jenkins -v /my_data/jenkins_home/:/var/jenkins_home jenkins/jenkins:lts

Step 4: Open the Jenkins webpage

Then we need to enter the container and view the password

# View the container list sudo docker ps 

Then enter the container according to the container ID

sudo docker exec -it 8c6be63a8fd5 /bin/sh

Then get the password

cat /var/jenkins_home/secrets/initialAdminPassword

Then fill in this password into the above web page.

Then an error may be reported: The cloudbees-folder plugin is missing

The solution is to go to Index of /packages/jenkins/plugins/cloudbees-folder/latest

After downloading, put it in war/WEB-INF/detached-plugins under the jenkins_home folder, and then restart the container.

Next, install the recommended plugins

Then create an administrator user and complete the Jenkins installation!
