My cloudbuild.yaml is failing. Please review my cloudbuild.yaml

Question

I am trying to set a react app to a kubernetes cluster. All my kubernetes files resides in k8s/ folder. In k8s/ folder I have a deployment.yaml and service.yaml file.

The below is my cloudbuild.yaml file which resides in the root folder. This part gcr.io/cloud-builders/kubectl Stage 3 is failing. I get the below error

build step 2 "gcr.io/cloud-builders/kubectl" failed: step exited with non-zero status: 1

steps:

# Build the image - Stage 1

Answer 1

In step 3, there are double quotes name: "gcr.io/cloud-builders/kubectl"

If you replace them with single quotes, the issue should be fixed.
