Write a Dockerfile for vetiver using valve — valve_write

A Valve powered vetiver Dockerfile will run prediction endpoints concurrently.

Usage

valve_write_vetiver(
  vetiver_model,
  plumber_file = "plumber.R",
  path = ".",
  port = 8000,
  vetiver_args = list(),
  workers = NULL,
  n_max = NULL,
  check_unused = NULL,
  max_age = NULL
)

Arguments

vetiver_model: A deployable vetiver_model() object
plumber_file: A path for your Plumber file, created via vetiver_write_plumber(). Defaults to plumber.R in the working directory.
path: A path to write the Dockerfile and lockfile, capturing the model's package dependencies. Defaults to the working directory.
port: The server port for listening: a number such as 8080 or an expression like 'as.numeric(Sys.getenv("PORT"))' when the port is injected as an environment variable.
vetiver_args: additional arguments passed to vetiver::vetiver_write_docker() as key-value pairs in a list object.

Value

The content of the Dockerfile, invisibly.

Details

This function is a modification of vetiver::vetiver_write_docker(). It modifies the created Dockerfile to install Valve, changes the ENTRYPOINT to use the Valve executable instead of a single plumber API via an R command.
