This is an image for Jenkins agent (FKA "slave") using JNLP to establish connection. This agent is powered by the Jenkins Remoting library, which version is being taken from the base Docker Agent image.
See Jenkins Distributed builds for more info.
To run a Docker container
docker run jenkinsci/jnlp-slave -url http://jenkins-server:port <secret> <agent name>
To run a Docker container with Work Directory:
docker run jenkinsci/jnlp-slave -url http://jenkins-server:port -workDir=/home/jenkins/agent <secret> <agent name>
Optional environment variables:
JENKINS_URL
: url for the Jenkins server, can be used as a replacement to-url
option, or to set alternate jenkins URLJENKINS_TUNNEL
: (HOST:PORT
) connect to this agent host and port instead of Jenkins server, assuming this one do route TCP traffic to Jenkins master. Useful when when Jenkins runs behind a load balancer, reverse proxy, etc.JENKINS_SECRET
: agent secret, if not set as an argumentJENKINS_AGENT_NAME
: agent name, if not set as an argument
By default, the JNLP3-connect is disabled due to the known stability and scalability issues.
You can enable this protocol on your own risk using the
JNLP_PROTOCOL_OPTS=-Dorg.jenkinsci.remoting.engine.JnlpProtocol3.disabled=false
property (the protocol should be enabled on the master side as well).
In Jenkins versions starting from 2.27
there is a JNLP4-connect protocol.
If you use Jenkins 2.32.x LTS
, it is recommended to enable the protocol on your instance.
Make sure your ECS container agent is updated before running. Older versions do not properly handle the entryPoint parameter. See the entryPoint definition for more information.
