Iterate with inline scripts

Sometime users may want to execute a script in their operation or to generate a file that can be used as an input for an init container or the main container without cloning a repo.

Running a python script

This example shows how to initialize a python script without cloning a repo or uploading code:

version: 1.1
kind: component
run:
  kind: job
  init:
    - file:
        content: |
          print("Hello World")
        filename: script.py
  container:
    image: polyaxon/polyaxon-quick-start
    workingDir: "{{ globals.artifacts_path }}"
    command: [python3, -u, script.py]

This example creates a file script.py in the init section and executes it in the main container.

Run the inline script

You can submit the complete Polyaxonfile above from the UI or the CLI.

Using the UI

In the quick-start project, open the create menu and select New job. Paste the Polyaxonfile into the editor, then select Create.

Open the create menu and select New job.

Paste the Polyaxonfile and create the job.

Using the CLI

Save the same Polyaxonfile as inline-script.yaml, then run:

polyaxon run -p quick-start -f inline-script.yaml -l

Similar to all other init containers, we could provide a custom path where the file should be initializer:

init:
  - file:
      content: |
        print("Hello World")
      filename: script.py
    path: custom/path/to/use

Running a bash script

version: 1.1
kind: component
run:
  kind: job
  init:
    - file:
        content: |
          echo 'This is a test.' | wc -w
        filename: script.sh
        chmod: "+x"
  container:
    image: polyaxon/polyaxon-quick-start
    workingDir: "{{ globals.artifacts_path }}"
    command: ['/bin/bash', '-c']
    args: ['./script.sh']

Initializing a YAML file

version: 1.1
kind: component
run:
  kind: job
  init:
    - file:
        content: |
          version: 1.1
          kind: component
          run:
            kind: job
            init:
              - file:
                  content: |
                    echo 'This is a test.' | wc -w
                  filename: script.sh
                  chmod: "+x"
            container:
              image: polyaxon/polyaxon-quick-start
              workingDir: "{{ globals.artifacts_path }}"
              command: ['/bin/bash', '-c']
              args: ['./script.sh']
        filename: polyaxonfile.yaml
        chmod: "+x"
  container:
    image: polyaxon/polyaxon-cli
    workingDir: "{{ globals.artifacts_path }}"
    command: ['polyaxon', "check", '-f']
    args: ['polyaxonfile.yaml']
