Configure Jenkins Agent with Docker

I generally followed these instructions though they prooved to be insufficient:

1 Create jenkins_agent_key pair; 2 Launch the agent agent1 - note use of host port 2222 being mapped to container’s port 22:

docker run -d --rm --name=agent1 -p 2222:22 -e "JENKINS_AGENT_SSH_PUBKEY=ssh-rsa AA....oabGtj7XFU= asokolsky@USSJC-ASOKOLSKY" jenkins/ssh-agent:alpine
VARS1="HOME=|USER=|MAIL=|LC_ALL=|LS_COLORS=|LANG="
VARS2="HOSTNAME=|PWD=|TERM=|SHLVL=|LANGUAGE=|_="
VARS="${VARS1}|${VARS2}"
docker exec agent1 sh -c "env | egrep -v '^(${VARS})' >> /etc/environment"

  1. Add agent1 to Jenkins as a permanent agent.

I set:

Launch the agent1, confirm success.
