Description: I followed Jenkins Artifactory Plugin - Setting Up Docker Build Info and got

java.lang.IllegalStateException: Build info capturing failed for docker image: artifactory.mycompany.com/mycompany/myproject/myservice:0.0.1.c62f0c8.72 check build info proxy configuration.

  ...

Docker/Server Setup:

• Instead of using only HTTP_PROXY in /etc/systemd/system/docker.service.d/http-proxy.conf, I also added NO_PROXY to be able to access to Artifactory artifactory.mycompany.com. Please note that adding or removing HTTPS_PROXY does not change anyting. None of the following configurations worked:
  /etc/systemd/system/docker.service.d/http-proxy.conf

  Environment="HTTP_PROXY=http://localhost:9765" "NO_PROXY=.mycompany.com"
  #Environment="HTTP_PROXY=http://localhost:9765" "HTTPS_PROXY=http://localhost:9765" "NO_PROXY=.mycompany.com"
  #Environment="HTTP_PROXY=http://10.74.200.52:9765" "NO_PROXY=localhost,127.0.0.0/8,.mycompany.com"
  #Environment="HTTP_PROXY=http://10.74.200.52:9765" "HTTPS_PROXY=http://10.74.200.52:9765" "NO_PROXY=localhost,127.0.0.0/8,.mycompany.com"
  

• Although Jenkins Artifactory Plugin - Setting Up Docker Build Info does not mention, I needed to execute sudo chmod 777 /var/run/docker.sock command to prevent following error:

  javax.ws.rs.ProcessingException: org.newsclub.net.unix.AFUNIXSocketException: Permission denied (socket: /run/docker.sock)

Jenkins Setup:

• There is no Jenkins agent and Jenkins master runs in Docker container.
• To be able to run docker command in the container, I prefered Docker outside of Docker(dood) solution
• exposed port 9765 for Artifactory Plugin's internal proxy
• used volume for Jenkins's data
• ran Jenkins container as swarm service
• Followed Jenkins Artifactory Plugin - Setting Up Docker Build Info by choosing port 9765
  

FROM artifactory.mycompany.com/jenkins

USER root

# To be able to build Docker images within the container, we have chosen 
# Docker outside of Docker(dood) solution in preference to Docker in 
# Docker(dind). By using dood we are able to execute "docker" commands
# without installing Docker into the container. See following
# pages to get better understanding of all the benefits of dood:
# - Jenkins with DooD (Docker outside of Docker): https://github.com/axltxl/docker-jenkins-dood
# - Running Docker in Jenkins (in Docker): http://container-solutions.com/running-docker-in-jenkins-in-docker/

docker push artifactory.mycompany.com/myjenkins

docker service create --name myjenkins -p 8080:8080 -p 50000:50000 -p 9765:9765 --replicas 1 \

Setup Test:

• On host machine;
  • Connected to port 9765 successfully: telnet localhost 9765
  • Executed following docker command successfully:

    docker pull artifactory.mycompany.com/hello-world
    

• On Jenkins;
  • Created a dummy job and executed the same docker command successfully.
