Jenkins
From charlesreid1
Basics
You develop Pipelines, the main object in Jenkins
Pipelines have 3 basic steps: build step, test step, and deploy (or "deliver") step.
Get Started
Installing
DigitalOcean guide to installing Jenkins on Ubuntu 16.04: https://www.digitalocean.com/community/tutorials/how-to-install-jenkins-on-ubuntu-16-04
wget -q -O - https://pkg.jenkins.io/debian/jenkins-ci.org.key | sudo apt-key add - echo deb https://pkg.jenkins.io/debian-stable binary/ | sudo tee /etc/apt/sources.list.d/jenkins.list sudo apt-get -y update sudo apt-get -y install jenkins
Starting
Jenkins runs as a service, so start it like this:
sudo systemctl start jenkins
Check its status like this:
sudo systemctl status jenkins
Should see something like this:
Output ● jenkins.service - LSB: Start Jenkins at boot time Loaded: loaded (/etc/init.d/jenkins; bad; vendor preset: enabled) Active:active (exited) since Thu 2017-04-20 16:51:13 UTC; 2min 7s ago Docs: man:systemd-sysv-generator(8)
Accessing
You should be able to access Jenkins at port 8080. (http://your-ip:8080)
If it is not available, you may nee to open port 8080 using your firewall (ufw or iptables or other).
To get your Jenkins admin secret, run:
sudo cat /var/lib/jenkins/secrets/initialAdminPassword
AWS
Spin up an AWS node.
Tasks:
IF setting up SSL:
- Open firewall port 8081 (security group)
- Set up nginx on the front end
- Obtain an SSL certificate for the domain that points to your server (you need a domain, not a bare IP address)
- Yes this is a pain in the ass. Good luck. You can find domains for as cheap as $0.40/month on Namecheap.com
- LetsEncrypt is how you get your certificate
- See https://git.charlesreid1.com/charlesreid1/certbot
- Set up nginx to reverse-proxy to port 8081
Otherwise:
- Open firewall port 8080 (security group)
Okay, now on to the rest:
- Set up nginx on the frontend for SSL
- Install Jenkins
- Access Jenkins
- Run a basic Python workflow
