I have been doing GCP- devops project course and I am not able to provision resources in GCP playground. What is the point of paying you if I have to create a separate gcp account?
Your screenshot shows you are trying to access Cloud Build Enterprise API. I highly doubt if playgrounds support that.
The GCP playgrounds are provided with a controlled environment with a limited set of permissions. This is due to various Security and Cost considerations. You can find the list of supported services and can work within the limit.
I am working on gcp-devops-project and I have done half the project using the playground but I got stuck when it reached the cloud build part. Also in the start of the course it says I can use kodekloud playground for the assignments in this course.
Your platform is totally misguiding in this aspect. Playgrounds are useless whether it is AWS or GCP can’t do anything advance.
