Printer

The instructions below will walk you through the process of launching a simple printer workflow using the Fuzzball workflow catalog. The workflow catalog will help you generate, validate, and submit a Fuzzfile representing the printer workflow. This workflow uses a public Alpine container from Dockerhub to print 1 integer every second for 5 minutes. This simple workflow will help familiarize you with the Fuzzball’s real-time logging feature, and can also be used to experiment with Fuzzball’s in-job terminal.

You can run this workflow either through the web UI or the CLI.

Please select either the web UI or CLI tab to see the appropriate instructions for your environment.

web UI

If you click “Workflow Catalog”, you will see a page of workflow templates you use to create fuzzfiles and launch workflows. Find the “Printer Example” tile with the CIQ badge and click “Run”.

You will be prompted with a pop-up showing template parameters which you can modify. If you’d like to accept the default values, you can click “Validate” which will validate the Fuzzfile generated using the input specified.

You can proceed to launching the job by clicking “Continue”.

You will be prompted to provide an optional descriptive name for your workflow.

Now you can click on “Start Workflow” in the lower right corner of the dialog box and your workflow will be submitted. If you click “Go to Status” you can view the workflow status page. The screenshot below shows the status page for a printer workflow submission.

To retrieve logs produced by this workflow, select the printer job within the workflow, and click the “Logs” option on the right.

CLI

To run this workflow through the CLI you will need access to the Fuzzball CLI. You can install it using the Fuzzball CLI installation instructions.

First, you can create a values file values.yaml to populate the printer example workflow template using the command below. You can modify the parameters to your desired values or use the defaults below.

$ cat >values.yaml<<EOF
values:
  - name: "Container"
    display_name: "container for printer job (must contain the sleep command)"
    string_value: "docker://docker.io/alpine:latest"
  - name: "Seconds"
    display_name: "How many seconds do you want the printer job to run and count?"
    uint_value: 300
EOF

Next, you will need to find the workflow template ID. The command below lists workflow templates provided by CIQ. The ID of the printer example workflow template shown in the output below is 00000010-aaaa-bbbb-cccc-dddddddddddd.

You can generate a Fuzzfile using the workflow ID and the values file (values.yaml) we created in the first step using the command below.

fuzzball application render-application 00000010-aaaa-bbbb-cccc-dddddddddddd values.yaml > printer.fz

You can start start this workflow using the CLI by running the following command:

$ fuzzball workflow start printer.fz
