Jenkins + Docker on Atomic Host

[Rishabh Das]

Hi,

I was trying to configure a Jenkins job to spin a docker container on the Atomic Host.  I configured Jenkins Docker plugin and added a Docker cloud and a Docker template for the image to be used. 

I attached a label to the docker image. While selecting 'Restrict where the project can be run' in the Jenkins job configuration, I specify the label. 

However it says 'Label is serviced by no nodes and 1 cloud'. Attached is a screenshot. While I build the job, the job status is Pending - waiting for next available executor.  Can anyone help ?

Anyone facing similar issue ?

Which image did you use for the docker provisioned agents? Did you configure the authentication?

Also: nothing in the logs while waiting?

I used the fedora base image. I created a docker file which uses the Fedora image, adds Jenkins public key to authorized_keys in the container.

I added the same in credentials in Jenkins.

test connection for the Atomic host is successful. It returns the version number. Attached are 2 screenshots of how the system is configured.

Being able to connect to the docker host is one thing, but it's unrelated to the image you define for use. Did you did for example install and configure sshd in that image?

It returns the same with every image. I also tried following the Jenkins Docker plugin page documentation on creating a docker image and adding it to Jenkins. Jenkins still returns with 'Label serviced by no nodes and 1 cloud'.
