Command-Line Interface#

CLI commands#

Use the following commands of the MLRun command-line interface (CLI) — mlrun — to build and run MLRun functions:

Each command supports many flags, some of which are listed in their relevant sections. To view all the flags of a command, run mlrun <command name> --help.

Building and running a function from a Git repository#

To build and run a function from a Git repository, start out by adding a YAML function-configuration file in your local environment. This file should describe the function and define its specification. For example, create a myfunc.yaml file with the following content in your working directory:

kind: job
metadata:
  name: remote-demo1
  project: ''
spec:
  command: 'examples/training.py'
  args: []
  image: .mlrun/func-default-remote-demo-ps-latest
  image_pull_policy: Always
  build:
    base_image: mlrun/mlrun:1.0.6
    source: git://github.com/mlrun/mlrun

Then, run the following CLI command and pass the path to your local function-configuration file as an argument to build the function’s container image according to the configured requirements. For example, the following command builds the function using the myfunc.yaml file from the current directory:

mlrun build myfunc.yaml

When the build completes, you can use the run CLI command to run the function. Set the -f option to the path to the local function-configuration file, and pass the relevant parameters. For example:

mlrun run -f myfunc.yaml -w -p p1=3

You can also try the following function-configuration example, which is based on the MLRun CI demo:

kind: job
metadata:
  name: remote-git-test
  project: default
  tag: latest
spec:
  command: 'myfunc.py'
  args: []
  image_pull_policy: Always
  build:
    commands: []
    base_image: mlrun/mlrun:1.0.6
    source: git://github.com/mlrun/ci-demo.git

Using a sources archive#

The -a|--archive option of the CLI build command enables you to define a remote object path for storing TAR archive files with all the required code dependencies. The remote location can be, for example, in an AWS S3 bucket or in a data container in an Iguazio MLOps Platform (“platform”) cluster. Alternatively, you can also set the archive path by using the MLRUN_DEFAULT_ARCHIVE environment variable. When an archive path is provided, the remote builder archives the configured function sources (see the -s|-source build option) into a TAR archive file, and then extracts (untars) all of the archive files (i.e., the function sources) into the configured archive location.

To use the archive option, first create a local function-configuration file. For example, you can create a function.yaml file in your working directory with the following content; the specification describes the environment to use, defines a Python base image, adds several packages, and defines examples/training.py as the application to execute on run commands:

kind: job
metadata:
  name: remote-demo4
  project: ''
spec:
  command: 'examples/training.py'
  args: []
  image_pull_policy: Always
  build:
    commands: []
    base_image: mlrun/mlrun:1.0.6

Next, run the following MLRun CLI command to build the function; replace the <...> placeholders to match your configuration:

mlrun build <function-configuration file path> -a <archive path/URL> [-s <function-sources path/URL>]

For example, the following command uses the function.yaml configuration file (.), relies on the default function-sources path (./), and sets the target archive path to v3io:///users/$V3IO_USERNAME/tars. So, for a user named “admin”, for example, the function sources from the local working directory will be archived and then extracted into an admin/tars directory in the “users” data container of the configured platform cluster (which is accessed via the v3io data mount):

mlrun build . -a v3io:///users/$V3IO_USERNAME/tars

Note:

  • . is a shorthand for a function.yaml configuration file in the local working directory.

  • The -a|--archive option is used to instruct MLRun to create an archive file from the function-code sources at the location specified by the -s|--sources option; the default sources location is the current directory (./).

After the function build completes, you can run the function with some parameters. For example:

mlrun run -f . -w -p p1=3
