Jenkins

https://jenkins.io/
https://github.com/jenkinsci/jenkins

Installing Jenkins on Ubuntu

https://wiki.jenkins-ci.org/display/JENKINS/Installing+Jenkins+on+Ubuntu

systemctl status jenkins.service
sudo systemctl start jenkins.service

http://loclahost:8080

sudo vim /var/lib/jenkins/secrets/initialAdminPassword
要存起來 之後就不見了

/var/log/jenkins/ Log生很快，容量超大

加入ssh key 到 github & jenkins

讓jenkins可以Clone with SSH
sudo su jenkins
ssh-keygen
cat .ssh/id_rsa.pub to github.com
Jenkins > Credentials > System > Global credentials (unrestricted) 選 Add Credentials 加入ssh

Proxy

可以收HTTP Request for webhook & 好看的網址
sudo a2enmod proxy proxy_http
sudo systemctl restart apache2.service
cd /etc/apache2/sites-available
sudo cp 000-default.conf jenkins.conf
sudo vim jenkins.conf
sudo a2ensite jenkins.conf

<VirtualHost *:80>
  ServerName "YOUR_JENKINS_URL"
  ProxyRequests Off
  <Proxy *>
    Order deny,allow
    Allow from all
  </Proxy>
  ProxyPreserveHost on
  ProxyPass / http://localhost:8080/ nocanon
  AllowEncodedSlashes NoDecode
</VirtualHost>

Jenkins > Jenkins Location > Jenkins URL > "YOUR_JENKINS_URL" > Apply

Build On Push (need setup proxy first)

Jenkins > Manage Jenkins > Configure System > 往下拉看到GitHub > Advanced... > Manage additional GitHub actions(Convert login and password to token) -> From login and password -> 拿到persional access token之後點上面 Add GitHub Server -> Credentials輸入剛剛的token -> Apply
似乎要 uncheck “manage hooks” 不然github上的設定會不見
http://jagdeesh1009.blogspot.tw/2016/04/jenkins-github-hooks-problems.html

到github專案網址 > Settings > Integrations & services > Add service > 搜尋Jenkins (GitHub plugin) > 輸入URL(預設http://x.x.x.x/github-webhook/) > 確定
可以點進去按Test

Jenkins > Your Project > Configure > Build Triggers > 勾GitHub hook trigger for GITScm polling

現在可到專案看 GitHub Hook Log
