Jenkins is an extensible open source continuous integration server. See the details from here.
Linux Foundation provides Jenkins for OPNFV. You can access it from this link.
The method that is normally used for connecting servers(slaves) to Jenkins requires SSH access to servers from outside. This may not be something to fix quickly for all the labs so we use the alternative way to connect slaves to Jenkins.
This alternative uses JNLP. Via JNLP, slaves open connection towards Jenkins instead of Jenkins accessing to them.
The server you want to connect to OPNFV Jenkins must have access to internet obviously.
Please follow below steps to enable this.
The slaves connected to OPNFV Jenkins using the method explained above are listed below.
The ones that don't have red cross next to computer icon are fully functional.
Certain things need to be set up in order to use Jenkins in CI. Below list contains some of the obvious ones.
This is used for connecting slaves to Jenkins. Whatever account is used for connecting slave(s) then used for executing jobs/build.
This account can also be used for running verification jobs on Git commits and giving +1/-1 if certain commit fails passing certain checks such as commit message format, PEP8, and so on. (Account name could be octopus.)
This defines who can do what and which credential is valid for which domain and so on.
These are the servers where the jobs/builds are executed.
These are the jobs that build software, test it and so on. See notes on Creating/Configuring/Verifying Jenkins Jobs
With plugins new functionality can be added to Jenkins in order to handle SCM stuff, create pipelines, throttle builds, logging/graphing, and so on.
Jenkins has hundreds of different plugins that can be installed in order to extend its functionality. One thing to keep in mind is installing huge number of plugins increases the load on the Jenkins master.
Full list of plugins can be seen from this link.
An easy option to get started with graphing performance and event logs from test runs is to just use Jenkins with some plugins.
The advantage to having Jenkins do this is the data is readily available for each job. As the number of jobs increased and mining, trends, and more sophisticated numerical data analysis and logging investigation is required the data can also be pushed to external databases such as splunk and logstash.
This plugin provides generic plotting (or graphing) capabilities in Jenkins.
This plugin will plot one or more single values variations across builds in one or more plots. Plots for a particular job (or project) are configured in the job configuration screen, where each field has additional help information. Each plot can have one or more lines (called data series). After each build completes the plots' data series latest values are pulled from Java properties file(s), CSV file(s), or XML file(s) via an XPath (which you should have generated during the build) somewhere below you workspace. Data for each plot is stored in a CSV file within the job's root project directory.
It can generate various kind of plots, including Area, Bar, Line, Stacked Bar, Waterfall…
