Jenkins pulling image from local registry: Client.Timeout exceeded while awaiting headers

I am running a docker registry locally on my machine, and I can pull my image from it successfully:

docker pull 192.168.174.205:5001/myimg:latest

I am also running a jenkins container on my machine, but Jenkins cannot pull any image from the local registry. I use a Blue Ocean container (on the same machine) to start a pipeline, and it outputs:

+ docker pull 192.168.174.205:5001/insureio:latest
Error response from daemon: Get https://192.168.174.205:5001/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)
script returned exit code 1

TMI

Specs

Docker version 1.13.1, build 4ef4b30/1.13.1
Jenkins ver. 2.204.2
host CentOS Linux 7 (Core)

Reference

I have been working from the instructions on

Settings

My /etc/docker/daemon.json file reads {"insecure-registries" : ["192.168.174.205:5001"]}.

The local registry gives a 200 response:

curl http://192.168.174.205:5001/v2/_catalog
{"repositories":["mying"]}

My pipeline script is:

node {
  stage('Build') {
    docker.withRegistry('http://192.168.174.205:5001') {
      docker.image('insureio:latest').inside('') {
        sh 'make test'
      }
    }
  }
}

Solution

Since both Jenkins and your registry are containers, Jenkins is going to be looking at the 192.168.174.205 IP address at its own network space.

If you're just trying things out, I would suggest doing a docker inspect <your registry container> | grep -i ipaddress to find its IP address (by default it should be in the region of 172.17.XXX.XXX) and configure your pipeline to use that address.
