一. install jenkins

1. in linux:

doc: https://www.jenkins.io/doc/book/installing/linux/#debianubuntu sudo apt update install java wget -q -O - https://pkg.jenkins.io/debian/jenkins.io.key | sudo apt-key add - sudo sh -c 'echo deb http://pkg.jenkins.io/debian-stable binary/ > /etc/apt/sources.list.d/jenkins.list' sudo apt update sudo apt install jenkins sudo systemctl start jenkins sudo systemctl enable jenkins

2. install by docker

After I install it on my linux host, I just find that there is existing image of jenckins on docker hub: https://www.jenkins.io/doc/book/installing/docker/ Don't forget use -v when use docker run jenkins

3. Error may come across

The following signatures couldn't be verified because the public key is not available:

a. NO_PUBKEY 3B4FE6ACC0B21F32

Fix: sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 5BA31D57EF5975CA ? ? ? ? ?sudo apt-get -y update ? ? ? ? ?sudo apt-get -y upgrade ? ? ? ? ?sudo apt-get -y update ? ? ? ? ?sudo apt install jenkins

b. run time issue

Job for jenkins.service failed becasused a timeout was exceeded See logs: ? ?journalctl -xeu jenkins.service ? ?systemctl status jenkins I fix it by: chown -R jenkins:jenkins /var/lib/jenkins

二. Internal net penetration

I need to vist my jenkins outside of my internal network which means I need a net penetration to get a public net ip/domain ngrok: ? Don't need any public network ip ? https://dashboard.ngrok.com/ ? 1. sign up on ngrok ? 2. got a auth token ? 3. install ngrok ? 4. setup the token ? 5. ngrok http http://localhost:${port your service use}, then it can random assign you a valiable domain

三. freestyle job

We usually use freestyle as our first jenkins job.

we can setup the github repository and crediential

node envroinment shell script

四. pipeline job(we usually leverage in our project)

1. workplace

by default it will locate at: /var/lib/jenkins/workspace/${project_name} or you could see it by: echo "Workspace directory is: ${env.WORKSPACE}"

2. post section:

It can always do something after all stages run out, or after success/failure ? ? post { ? ? ? ? always { ? ? ? ? ? ? cleanWs() ? ? ? ? } ? ? ? ? success { ? ? ? ? ? ? archiveArtifacts artifacts: 'a.txt' ? ? ? ? } ? ? }

3. env variable and parameters

? ?parameters { ? ? ? ? string(name: 'TEST1', defaultValue: 'test', description: 'test') ? ? ? ? booleanParam(name: 'SKIP_E2E', defaultValue: false, description: 'skip e2e or not') ? ? } ? ? environment { ? ? ? ? HELLO_WORLD = "Hello World" ? ? }?
