Cloud Functions As List Of Members Service
Using the Google Cloud Functions (Go 1.11.5 runtime), I have implemented a simple list of members service with Google Firestore.
After preparing the environment, we start setting some environment variables:
- GCP_PROJECT=<project id>
- GOOGLE_APPLICATION_CREDENTIALS=<json file>
- GCP_REGION=<region>
We use Go modules for our dependencies, therefore, having the source files in place, we execute the following:
export GO111MODULE=on
go mod init && go mod vendor
Now, we can deploy our functions:
gcloud alpha functions deploy subscribe --region $GCP_REGION --entry-point Subscribe --runtime go111 --trigger-http
gcloud alpha functions deploy list --region $GCP_REGION --entry-point List --runtime go111 --trigger-http
gcloud alpha functions deploy unsubscribe --region $GCP_REGION --entry-point Unsubscribe --runtime go111 --trigger-http
gcloud alpha functions deploy reset --region $GCP_REGION --entry-point Reset --runtime go111 --trigger-http
Using the URL from the deployment, we test the functions:
curl <url>/subscribe <name> <ip> <port>
curl <url>/list
curl <url>/unsubscribe <id>
curl <url>/reset
