# Usage jenkins-agent.sh [options] -url http://jenkins -secret [SECRET] -name [AGENT_NAME]
# Optional environment variables :
# * JENKINS_JAVA_BIN : Java executable to use instead of the default in PATH or obtained from JAVA_HOME
# * JENKINS_JAVA_OPTS : Java Options to use for the remoting process, otherwise obtained from JAVA_OPTS
# * JENKINS_TUNNEL : HOST:PORT for a tunnel to route TCP traffic to jenkins host, when jenkins can't be directly accessed over network
# * JENKINS_URL : alternate jenkins URL
# * JENKINS_SECRET : agent secret, if not set as an argument
# * JENKINS_AGENT_NAME : agent name, if not set as an argument
# * JENKINS_AGENT_WORKDIR : agent work directory, if not set by optional parameter -workDir
# * JENKINS_WEB_SOCKET: true if the connection should be made via WebSocket rather than TCP
# * JENKINS_DIRECT_CONNECTION: Connect directly to this TCP agent port, skipping the HTTP(S) connection parameter download.
# Value: "<HOST>:<PORT>"
# * JENKINS_INSTANCE_IDENTITY: The base64 encoded InstanceIdentity byte array of the Jenkins controller. When this is set,
# the agent skips connecting to an HTTP(S) port for connection info.
# * JENKINS_PROTOCOLS: Specify the remoting protocols to attempt when instanceIdentity is provided.
