Jenkins Docker Plugin with custom registry

[Markus Petzsch]

Hello List,

I am trying to provision jenkins build slaves (docker templates) on demand
with the docker plugin. The build images are stored in a local registry
which requires credentials. Now I came across the following screenshot where
the user was able to specify the custom registry:

https://user-images.githubusercontent.com/28305157/31658912-566eef16-b32a-11
e7-810e-a3308769a911.png

This option does not exist on my jenkins installation however (There is only
a button to add registry credentials - odd enough).

In the logs I get the following messages:

I'm using the Jenkins docker image with the following docker plugins and
versions:

Docker API Plugin 3.0.14
Docker Commons Plugin 1.11
Docker Pipeline 1.14
Docker plugin 1.1.2

Any help with this is highly appreciated.

Best Regards

Hello again,

I found the solution myself. Putting the registry into the image name like so
solved it:

registry:4567/XXX/buildslaves:java

Best Regards
