| 3 | This program runs on a worker host. It is invoked by [[Crunch2 dispatch]] (possibly via slurm or ssh). Its responsibilities include: |
||
| 4 | * Retrieve the Container record with the given UUID |
||
| 5 | * Load the specified docker image from Keep |
||
| 6 | * Translate the Container specification to a "docker run" command line |
||
| 7 | * Start arv-mount on the host (if required by the container) and shutting it down when the container exits |
||
| 8 | * Impose runtime constraints, using "docker run" arguments and other facilities |
||
| 9 | * Report resources used by the container while it runs (presumably using crunchstat) |
||
| 10 | * Update the Container record to reflect the actual state of the container (progress/completion) |
||
| 11 | * Forward the container's stderr output to the Arvados API as Log entries (subject to configurable throttle) |
||
| 12 | * Save the container's output in the Container record (if applicable) |
