… using docker (#1549) ### Motivation Running OpenCue In a multi operational system environment requires segregating the farm, which means hosts have to be assigned to one OS and cannot be shared between shows that have different OS requirements. This can be a challenge when sharing resources between shows is necessary. ### Proposed solution A new execution mode on **rqd** `runDocker` to live alongside `runLinux`, `runWindows`, and `runDarwin` (macOs). This mode will launch the frame command on a docker container based on the frame expected OS. With this, rqd is now able to run jobs from different OSs on the same host. But to make this possible, a rqd host needs to advertise itself not with its own OS code (defined by `SP_OS` on rqd.conf), but with all the OSs of images it is capable of executing. ### Configuration changes The following sections were added to rqd.conf: ```ini [docker.config] # Setting this to True requires all the additional "docker.[]" sections to be filled RUN_ON_DOCKER=True # This section is only required if RUN_ON_DOCKER=True # List of volume mounts following docker run's format, but replacing = with : [docker.mounts] TEMP=type:bind,source:/tmp,target:/tmp,bind-propagation:slave NET=type:bind,source:/net,target:/net,bind-propagation:slave # This section is only required if RUN_ON_DOCKER=True # - keys represent OSs this rqd is capable of executing jobs in # - values are docker image tags [docker.images] centos7=centos7.3:latest rocky9=rocky9.3:latest ``` In this case, the rqd host would advertise itself with `OS=centos7,rocky9`, and the dispatch logic has been changed accordingly to account for dispatching frames to nodes that support multiple OSs.
