Bug #19281
Updated by Tom Clegg over 2 years ago
The diagnostics run a test container to verify that crunch is working. However, it assumes that an @alpine@ image (or a different image specified on the command line, perhaps @arvados/jobs:latest@) arvados/jobs:latest has been loaded. Our install process doesn't load any images, do that, because arvados-cwl-runner is responsible for loading the image that corresponds to the exact version of a-c-r being used, on demand. Running the "/hello" command with the "hello-world" image would work just as well, and that image is only ~20KB. The diagnostics command should embed either be able to load the hello-world arvados/jobs image, be able to pull and upload it to Keep at runtime, instead of relying load some other image (maybe an alpine image, served from jutro), or give instructions on the docker daemon being installed/working on the client host. Continue how to support the @-docker-image=...@ option as well (assume the image is already uploaded). Requested command should be @/hello@ if using the @hello-world@ image, otherwise @echo {timestamp}@. load an image.
