Python Examples

Building using a Python Build pack

from servicefoundry import Service, Build, PythonBuild, Port

service = Service(
    name="my-service",
  	image=Build(
      build_spec=PythonBuild(
          python_version="3.9",
          requirements_path="requirements.txt",
          command="uvicorn app:app --port 8080 --host 0.0.0.0", # or as a list ["python", "main.py"]
      )
    ),
    ports=[Port(port=8080)]
)

deployment = service.deploy(workspace_fqn='...')

Building using a Dockerfile

This is useful if you have an already written Dockerfile

from servicefoundry import Service, Build, DockerFileBuild, Port

service = Service(
    name="my-service",
  	image=Build(
      build_spec=DockerFileBuild(),
    ),
    ports=[Port(port=8080)]
)

deployment = service.deploy(workspace_fqn='...')

Using an already existing Image from an Image Registry

Note: The remote Image Registry should either be public or added to Truefoundry Platform via the Integrations Tab

from servicefoundry import Service, Image, Port

service = Service(
    name="my-service",
  	image=Image(
      image_uri="seldonio/mlserver:1.2.0",
    ),
    ports=[Port(port=8080)]
)

deployment = service.deploy(workspace_fqn='...')

Deploying from a Git Repository

Note: The remote Git server (Github or Bitbucket) needs to be connected via the Integrations Tab

from servicefoundry import (
    Service, Build, GitSource, PythonBuild, Resources,
    Port, HealthProbe, BasicAuthCreds, HttpProbe
)

service = Service(
    name="my-service",
