Tutorial deploying Flask on IBM Cloud

  • 1.  Tutorial deploying Flask on IBM Cloud

    Hi,

    I am doing the following tutorial to deploy Flask applications.
    IBM Cloud Docs
    Now I am at steps 6. 
    When I do 

    python hello.py

    to run on my local machine, I get the following error message in my Command :

    Found local VCAP_SERVICES
    Traceback (most recent call last):
    File "hello.py", line 31, in <module>
    creds = vcap['services']['cloudantNoSQLDB'][0]['credentials']
    KeyError: 'services'

    I already created the needed .json file and copied and pasted all the necessary code.

    Please help.

    thanks,
    Naveen

    Hi Naveen,
     
    It seems like you are encountering an error while running your Flask application locally. The error message suggests that there is a KeyError for the 'services' key in your VCAP_SERVICES environment variable.
     
    Here are a few steps you can try to resolve this issue:
     
    1. Double-check your code: Make sure that you have correctly copied and pasted all the necessary code from the tutorial, especially the parts related to setting up the VCAP_SERVICES environment variable.
     
    2. Verify your .json file: Ensure that the .json file you created contains the correct credentials for the cloudantNoSQLDB service. Check if the 'services' key is present and if it contains the necessary information.
     
    3. Check your environment variables: Confirm that the VCAP_SERVICES environment variable is properly set on your local machine. You can do this by running the `print(os.environ.get('VCAP_SERVICES'))` command in your code to see the value.
     
    4. Ensure dependencies are installed: Make sure that you have installed all the required dependencies for your Flask application, including any libraries or packages mentioned in the tutorial.
     
    If you have followed these steps and the issue persists, it might be helpful to provide more details about your environment setup, such as the versions of Python and Flask you are using, as well as any relevant code snippets. This will allow others to better assist you in troubleshooting the problem.
     
    Best of luck with your Flask deployment, and feel free to reach out if you have any further questions!
     
    Best regards,
    [Your Name]
