When I try to run the check_dcloud.py I get a traceback:

(dna) cisco@ubuntu:~/CiscoDevNet/code/dna/LM-4302$ python3 check_dcloud.py

Traceback (most recent call last):

I posted in the

DevNet Learning Labs

but got no reply

I opened a case with dCloud and they pointed me back here

I just span up another lab to see if the fault disappeared and it did not so it was not an issue specific to the instances I span up

Hi Steve,

In order to successfully run the check_dcloud.py script fist you will need to populate SPARK_TOKN and SPARK_ROOM variables located in hello_lab.py file.

Spark token can be obtained from https://developer.ciscospark.com/ page. After successful authentication, click on your avatar picture and access token will be displayed.

From Cisco Spark, pick a room where you would like to post a message and assign it to the SPARK_ROOM variable.

After that run the script and you should see a message on your terminal confirming that dCloud pod is ready for the labs.

PS. I will update the script so it will notify the user that important variables need to be populated.

Thank you!
