App Engine Flexible Environment - Pub/Sub Sample

Clone the sample app

Copy the sample apps to your local machine, and cd to the pubsub directory:

git clone https://github.com/GoogleCloudPlatform/ruby-docs-samples
cd ruby-docs-samples/appengine/pubsub

Create a topic and subscription

Create a topic and subscription, which includes specifying the endpoint to which the Pub/Sub server should send requests:

gcloud beta pubsub topics create <your-topic-name>
gcloud beta pubsub subscriptions create <your-subscription-name> \
  --topic <your-topic-name> \
  --push-endpoint \
  https://<your-project-id>.appspot.com/pubsub/push?token=<your-token> \
  --ack-deadline 30

Run

Make sure gcloud is installed and authenticated. You can find your project id with gcloud config list. The token should be any random string.

export PUBSUB_VERIFICATION_TOKEN=<your-token>
export PUBSUB_TOPIC=<your-topic-name>
export GOOGLE_CLOUD_PROJECT=<your-project-id>
bundle
bundle exec ruby app.rb

visit on http://localhost:4567/

send fake push messages with:

curl -i --data @sample_message.json "localhost:4567/pubsub/push?token=<your-token>"

Deploy

To deploy to the App Engine standard environment, put topic and token in app.standard.yaml, then:

gcloud app deploy app.standard.yaml

To deploy to the App Engine flexible environment, put topic and token in app.yaml, then:

gcloud app deploy app.yaml

Test

Note: the tests do a live deploy to App Engine

Put a client_secrets.json file for a service account in the root of your repo.

gcloud auth activate-service-account --key-file ../../client_secrets.json
export GOOGLE_CLOUD_PROJECT=<your-project-id>
export TEST_DIR=appengine/pubsub/
bundle exec rspec
