 You can specify and set the number of executors of your Jenkins master instance using a groovy script. By default its set to 2 executors, but you can extend the image and change it to your desired number of executors :
 
+`executors.groovy`
 ```
-# executors.groovy
+import jenkins.model.*
 Jenkins.instance.setNumExecutors(5)
 ```
