 6 | [`csanchez/jenkins-slave`](https://hub.docker.com/r/csanchez/jenkins-slave/)

 8 | A [Jenkins](https://jenkins-ci.org) slave using JNLP.

10 | See [Jenkins Distributed builds](https://wiki.jenkins-ci.org/display/JENKINS/Distributed+builds) for more info.

12 | For a container with swarm plugin see

14 | 
15 | ## Running
16 | 
17 | To run a Docker container
18 | 
19 |     docker run csanchez/jenkins-slave -url http://jenkins-server:port <secret> <slave name>
20 | 
21 | If the command line options are not set it will try to use environment variables,
22 | including Kubernetes set variables for services `jenkins` and `jenkins-slave`.
23 | 
24 | * `JENKINS_URL`: url for the Jenkins server
25 | * `JENKINS_SERVICE_HOST` and `JENKINS_SERVICE_PORT`: will be used to compose the url if the previous is not present.
26 | * `JENKINS_TUNNEL`: (`HOST:PORT`) connect to this slave host and port instead of Jenkins server
27 | * `JENKINS_SLAVE_SERVICE_HOST` and `JENKINS_SLAVE_SERVICE_PORT`: will be used to compose the tunnel argument if the previous is not present.
