Lab 2.4: Run a workflow with f5-newman-wrapper

In this lab we will use the f5-super-netops-container to run the workflow we reviewed in the previous lab. The advantage of using the f5-super-netops Container is that all the tools, collections and frameworks are pre-installed and ready to use.

Task 1 - Run a f5-newman-wrapper Workflow

  1. Return to, or open an SSH session as described in the previous lab. If you need to launch the container once more, follow the instructions in this previous lab and log in as snops

  2. Run cd f5-postman-workflows/local

  3. Run cp ../workflows/Wrapper_Demo_1.json .

  4. Edit the Wrapper_Demo_1.json file with vim and enter the 10.1.1.10 for the value of the bigip_mgmt variable

    "globalVars": {
        "bigip_mgmt": "10.1.1.10",
        "bigip_username":"admin",
        "bigip_password":"admin"
},

  5. Run f5-newman-wrapper Wrapper_Demo_1.json

  6. Examine the output to see how the workflow was executed. Notice that the same tests that we saw when using Postman are present during this run.

    Example output:

    [snops@f5-super-netops] [~/f5-postman-workflows/local] $ f5-newman-wrapper Wrapper_Demo_1.json

  ]
}

Notice that the bigip_version and bigip_build variables were saved, similar to how this was shown in the Postman GUI Environment Variables. This file is JSON formatted and can easily be used directly by other tools to drive further automation.
