keep the docker container alive even on job failure and re use it for replay

[Mallarapu Ananth]

Hi all , 

I am looking for a feature where i need to docker container to be alive even the job failed . to give the context , i am trying to develop do build which take long time and whenever it build fails at some point i need to do all the steps again . to avoid this i need to docker container to be alive even when job get failed . 

in addition to this i should be able to use the same docker container to replay the same job again form a later stage . 

i looked at the issues page for a while but couldn't find any similar ones . if anyone has faced the issue let me know your thought on how can this problem be solved .

Don't start the container by the long-running job. Setup a second job that starts the container, so that the first job may fail without affecting the container.
