Run the job by executing this command with your chosen configuration, exposing port 5000 to the outside world:
docker run training-job-template
To enable the Nvidia Container Runtime for GPU-acceleration, execute:
docker run --runtime=nvidia training-job-template
Execute this command for interactive run mode:
docker run -it --entrypoint=/bin/bash training-job-template
More options:
- publish the container's port 5000 via to
host_port
usinng-p {host_port}:5000
- for testing purposes (fast execution), run with
--env-file==test.env
. - run in detached mode usingn
-d
The training job can be parametrized with environment variables. These can be defined by passing an environment file via --env-file=={env_file}
to docker run
. To learn about available variables, click here.
The training job can be configured with following environment variables:
Variable | Description | Default |
---|---|---|
Training Config: | ||
N_EPOCHS | no. training epochs | 10 |
SEED | Global seed used for random numbers. | 42 |
Computation Config: | ||
MAX_NUM_THREADS | Controls which GPUs CUDA applications will see. By default, all GPUs from the host are used. You can either use all, none, or specify a comma-separated list of device IDs (e.g. 0,1). You can find out the list of available device IDs by running nvidia-smi on the host machine. | auto |
NVIDIA_VISIBLE_DEVICES | (GPU only) Controls which GPUs will be accessible by the job. By default, all GPUs from the host are used. You can either use all, none, or specify a comma-separated list of device IDs (e.g. 0,1). You can find out the list of available device IDs by running nvidia-smi on the host machine. | all |
CUDA_VISIBLE_DEVICES | (GPU only) Controls which GPUs will be accessible by the job. By default, all GPUs that the job has access to will be visible. To restrict the job, provide a comma-separated list of internal device IDs (e.g. 0,2) based on the available devices within the container job (run nvidia-smi). In comparison to NVIDIA_VISIBLE_DEVICES, the job user will still able to access other GPUs by overwriting this configuration from within the container. | all |
Cloud Config: |
If a proxy is required, you can pass it via the http_proxy
and no_proxy
environment varibales. For example: --env http_proxy=<server>:<port>
You can find more ways of configuration about docker run and docker service create in the official Docker documentation.

Execute this command in the project root folder to build the docker container:
python build.py --version={MAJOR.MINOR.PATCH-TAG}
The version has to be provided. The version format should follow the Semantic Versioning standard (MAJOR.MINOR.PATCH). For additional script options:
python build.py --help
Execute this command in the project root folder to push the container to the configured docker registry:
python build.py --deploy --version={MAJOR.MINOR.PATCH-TAG}
The version has to be provided. The version format should follow the Semantic Versioning standard (MAJOR.MINOR.PATCH). For additional script options:
python build.py --help
In order to pull and push docker containers, a Docker registry needs to be configured:
docker login <server>
and your user and password to login.
