Section Number and Name:
Creating the RHCOS cluster image for the GCP infrastructure
Step 4 Export the uploaded RHCOS image location as a variable:

export IMAGE_SOURCE=`gs://<bucket_name>/rhcos-<version>-x86_64-gcp.x86_64.tar.gz`

Describe the issue:
The command is
export IMAGE_SOURCE=`gs://<bucket_name>/rhcos-<version>-x86_64-gcp.x86_64.tar.gz`

It contains extra single quote wrapping the command and the command doesn't work.

Suggestions for improvement:

Remove the single quotes

export IMAGE_SOURCE=gs://<bucket_name>/rhcos-<version>-x86_64-gcp.x86_64.tar.gz

Additional information:
The command, as it is written now, does not work:
$ export IMAGE_SOURCE=`gs://preserve-tsze/rhcos-4.9.0-fc.0-x86_64-gcp.x86_64.tar.gz`
bash: gs://preserve-tsze/rhcos-4.9.0-fc.0-x86_64-gcp.x86_64.tar.gz: No such file or directory
