Hi folks, I'm trying to setup a Mesos cluster and submit the "hello world" GPU example from the documentation page:
*"mesos-execute --master=10.120.59.5:5050 <http://10.120.59.5:5050> --name=gpu-test --docker_image="nvidia/cuda" --command="nvidia-smi" --framework_capabilities="GPU_RESOURCES" --resources="gpus:1"* This returns: I0720 16:02:26.039414 102623 scheduler.cpp:184] Version: 1.3.0 I0720 16:02:26.040221 102619 scheduler.cpp:470] New master detected at master@10.120.59.5:5050 Subscribed with ID 4d3b5156-85df-4ffd-a8cd-9e0ecaa90e39-0015 Submitted task 'gpu-test' to agent 'b2d906e8-1207-4ceb-aeb0-42be1150cff8-S4' Received status update TASK_FAILED for task 'gpu-test' message: 'Failed to launch container: Failed to perform 'curl': curl: (7) Failed to connect to registry-1.docker.io port 443: Connection refused ' source: SOURCE_AGENT reason: REASON_CONTAINER_LAUNCH_FAILED --- Now when specifying the containerizer=docker I receive the following output: mesos-execute --containerizer=docker --master=10.120.59.5:5050 --name=gpu-test --docker_image="nvidia/cuda" --command="nvidia-smi" --framework_capabilities="GPU_RESOURCES" --resources="gpus:1" I0720 16:02:59.589102 102719 scheduler.cpp:184] Version: 1.3.0 I0720 16:02:59.589792 102727 scheduler.cpp:470] New master detected at master@10.120.59.5:5050 Subscribed with ID 4d3b5156-85df-4ffd-a8cd-9e0ecaa90e39-0016 Submitted task 'gpu-test' to agent 'b2d906e8-1207-4ceb-aeb0-42be1150cff8-S3' Received status update TASK_RUNNING for task 'gpu-test' source: SOURCE_EXECUTOR Received status update TASK_FAILED for task 'gpu-test' message: 'Container exited with status 127' source: SOURCE_EXECUTOR So still no success, but a different error. My environment does have http_proxy and https_proxy variables with proper values and I've set them before starting the agents. Both docker and nvidia-docker pull works just fine and can download the images. Any thoughts on how to fix or troubleshoot this ? Thank you! Version: Mesos 1.3.0 OS: Ubuntu 16.04 Docker: 17.06.0-ce (+ NVIDIA-Docker) -- ~/William
