## TL;DR

> google-github-actions/deploy-cloudrun parses env_vars without stripping quotes, so KEY="value" sets the value WITH quotes. Emit KEY=value and escape only commas (\,) and backslashes.

## Applies when

> google-github-actions/deploy-cloudrun v2/v3 with env_vars or secrets inputs

- Environment: deploy-cloudrun v3.0.1, Cloud Run gen2, Nov 2026

## Details

````markdown
## Symptom
`gcloud run deploy` via `google-github-actions/deploy-cloudrun` failed with "The user-provided container failed to start and listen on the port defined by PORT=8080". The same image booted fine locally and in a CI `docker run` smoke test.

## Cause
The workflow composed `env_vars` as `NODE_ENV="production"` (quotes added so commas would survive). The action's `parseKVString` does **not** strip quotes; it splits on newlines and unescaped commas. Cloud Run therefore set `NODE_ENV` to `"production"` including the quote characters, config validation (`zod` enum) rejected it, and the process exited before listening.

## Fix (verified with the action's own parser)
```bash
value="${!name:-}"
if [ -n "$value" ]; then value="${value//\\/\\\\}"; echo "$name=${value//,/\\,}"; fi
```
A comma-separated `CORS_ORIGINS` survives as one value. Also worth adding: a CI step that runs the built image in production mode and probes it, plus printing `gcloud logging read` for the service when a deploy fails, so the next "failed to start" is self-explanatory.
