Environment: Linux, Docker plugin, docker 1.8.1
Priority: Critical Critical

Jenkins ver. 1.626
Docker plugin version: 0.12.1

Container settings:
Docker command: /sbin/init 3 (without custom command also crashes)
Hostname: debian8_32bit_32bit_INIT3_CONTAINER
DNS: <Some ip address>
Volumes: /sys/fs/cgroup:/sys/fs/cgroup:ro
Environment: container=docker
Privileged : true
Remote filing root: /home/jenkins
labels: debian8_32bit_32bit_INIT3_CONTAINER

Port: 22

Problem:
Crash when running a job. The container is started within docker server but jenkins cannot see it. Jenkins logs state:

provide full description of issue
--> Upgrade

Jenkins ver. 1.626
Docker plugin version: 0.12.1

Plugin started producing the mentioned error.

check Manage Jenkins -> Manage Old Data for not updated configuraiton and provide this info
--> "No old data was found."

provide full list of installed plugins with versions, jenkins core version
--> Please see PluginsInstalled Attachment.

check and provide errors from system jenkins.log and errors from Manage Jenkins -> System Log
--> Already added to the bug when reporting.

provide Cloud section from $JENKINS_HOME/config.xml file
--> the cloud section contains a lot of images. I am attaching partially in "clouds_section_config.xml".

describe how your docker infrastructure looks like
--> 2 docker servers, around 84 containers. The docker servers and Jenkins are all separate Virtual machines.
--> The jobs are all sequential, running one container at a time.

provide docker host/api version
--> Tried two docker versions 1.6.1 and 1.8.1

provide steps for reproducing
--> Just create a node with the mentioned configuration and jenkins and docker version as written before. Run a job. The run fails.

any code or log example surround with right markdown https://help.github.com/articles/github-flavored-markdown/
--> configuration and logs already attached.

Re: Nullpointer exception while connecting to a docker container

Another Observation:
Downgrading to Docker plugin v 0.9.2 and using Docker v 1.6.1 again works.

Thanks for verbose output. So is it an newer API issue or docker-plugin bug?

Also please increase DockerOnceRetentionStrategy timeout to 10 as it may kill Slave randomly.

Tom Canova please provide full log, also to what ip and port is it trying connect and what is the right ip/port of running container (login into docker host and docker inspect appeared containerId)?

So, I tried with the latest docker plugin, version 0.14.0, and I can connect to the docker service.
The problem that I now have is that I cannot use docker version > 1.8.0 with jenkins, but as I read above, this might be due to the custom containers that I create.
So, Please let me know what I should I change while creating containers to make them work with docker > 1.8.0 and latest docker plugin?

Thanks,
Ashish.

 Thanks,

JENKINS-30200: Nullpointer exception while connecting to a docker
container

Looks like due to Docker API changes between `v1.19` and `v1.20`
create container call should contain `ExposedPorts` instead of
`PortSpecs`. Change was tested with Docker `1.8.2` and `1.7.1`.
