Push image with pipeline

Hello all,

I’m trying to create a docker image and push it to harbor (out of k8s and rancher).
for each run, i have the same problem.

00:33:13 Successfully tagged 00000000:latest
00:33:13 + /usr/local/bin/docker tag 00000000 <IP>/mademo/mademoimage:0.1
00:33:13 + /usr/local/bin/docker push <IP>/mademo/mademoimage:0.1
00:33:13 The push refers to repository [<IP>/mademo/mademoimage]
00:33:13 Get https://<IP>/v2/: dial tcp <IP>:443: getsockopt: connection refused
00:33:13 time="2019-02-15T00:33:13Z" level=fatal msg="exit status 1"

All docker for k8s and rancher run with ExecStart=/usr/bin/dockerd --insecure-registry=IP

Do you have an idea ?
Thanks
