Google Cloud Build - Multiple Environments - google-cloud-platform

Question

In my app, I have the following:
app.yaml
cloudbuild.yaml
I use the above for the first time to deploy the default service.
app.qa.yaml
cloudbuild_qa.yaml
app.staging.yaml
cloudbuild_staging.yaml
app.prod.yaml
cloudbuild_prod.yaml
They all reside at the root of the app.
For instance, the cloudbuild_qa.yaml is as follows:
steps:
- name: node:14.0.0
entrypoint: npm
args: ['install']
- name: node:14.0.0
entrypoint: npm
args: ['run', 'prod']
- name: 'gcr.io/cloud-builders/gcloud'
args: ['beta', 'app', 'deploy', '--project', '$PROJECT_ID', '-q', '$_GAE_PROMOTE', '--version', '$_GAE_VERSION', '--appyaml', 'app.qa.yaml']
timeout: '3600s'
The Cloud Build works well, however, it's not respecting the app.qa.yaml instead, it always takes the default app.yaml.
Services to deploy:
descriptor: [/workspace/app.yaml]
source: [/workspace]
target project: [test-project]
target service: [default]
target version: [qa]
target url: [https://test-project.uc.r.appspot.com]
Any idea what's happening? Do you know how to use the correct app.yaml file in such a case?

Answer 1

Remove the '--appyaml', in the attribute list.
However, I'm not sure that is a good practice to have a deployment file different from an environment to another one. When you update something at a place, you could forget to update the same thing in the other files.
Did you think to replace placeholders in the files? or to use substitution variables in the Cloud Build?

Answer 2

In our build we are using:
steps:
- name: 'gcr.io/cloud-builders/gcloud'
args: ['app', 'deploy', '--appyaml=app-qa.yaml', '--no-promote', '--version=${_TAG_VERSION}']
FYI:
I've notice you are building your applications using the node builder but you could add the script gcp-build in your package.json because the script gcloud app deploy should look for scripts named gcp-build and execute them before deploying
{
"scripts": {
...
"build": "tsc",
"start": "node -r ./tsconfig-paths-dist.js dist/index.js",
"gcp-build": "npm run build"
},
}
