Jenkins continuous integration environment construction V (Jenkins common construction triggers)

---

1. Jenkins Trigger type

Jenkins built-in 4 Build triggers ：

• Trigger remote build
• Trigger after other projects are built （Build after other projects are build）
• Time to build （Build periodically）
• polling SCM（Poll SCM）

2. Trigger remote build

stay web_demo_pipeline In the project configuration

Application save .

Authentication token random , Just remember （ Tokens are actually best encrypted , There is no need to demonstrate here ）

Remotely triggered built url：http://192.168.10.30:8888/job/web_demo_pipeline/build?token=8888
Browser login this URL, Trigger Jenkins An automated build .

Let's change it IDEA Code in , Resubmit to Gitlab.

see Tomcat Publish results

3. Trigger after other projects are built

establish pre_project Assembly line engineering

Pre engineering is only an example , Unwanted git Pull the code , Just output a line of statements .

go back to web_demo_pipeline Project configuration

Start building front projects

We build the pre project manually , After the pre engineering construction is completed, it will trigger web_demo_pipeline Automatic construction of projects .

see web_demo_pipeline Whether to build automatically

modify IDEA Resubmit the code .

4. Time to build

The timing strings from left to right are ：

 branch   when   Japan   month   Zhou 

Some examples of timed expressions ：

 Every time  30  Build once in minutes (H  On behalf of the parameter )：H/30 * * * *
 Every time  2  Build once an hour : H H/2 * * *
 Daily  8  spot ,12  spot ,22  spot , Build... In a day  3  Time ( Multiple time points are separated by commas )：0 8,12,22 * * *
 Every day at noon  12  Build once on a regular basis ：H 12 * * *
 Every afternoon  18  Build once on a regular basis ：H 18 * * *
 Every... In the first half of every hour  10  minute ：H(0-29)/10 * * * *
 Every two hours , Every weekday in the morning  9  Point to the afternoon  5  spot ( Maybe in the morning 10:38, Afternoon 12:38, Afternoon 2:38, Afternoon 4:38)：H H(9-16)/2 * * 1-5

go back to web_demo_pipeline engineering

PS： Cancel the scheduled construction after the experiment ！

5. polling SCM

polling SCM, When specified, scan the local code warehouse for code changes , If the code changes, the project build is triggered .

Be careful ： This time build triggers ,Jenkins The code of the whole local project will be scanned regularly , Increase the cost of the system , Not recommended .

modify IDEA Code and submit to Gitlab
