Goals:

1. Practice TDD
2. Scrape a web page using Python's Beautiful Soup
3. Run in Cloud Run
4. Set up a Schedule
5. Write a log-based metric which Stackdriver can have an alert for (because there's no SMTP service in GCP!)

• Bootstrap project
• Init BeautifulSoup
• Search for word on cinema booking page!
• Run in Cloud Run
• Convert to authenticated access only
• Wire up a Schedule
• Generate Log-Based Metric
• Create Alert in Stackdriver
• Check receive alert
• Convert metric & alert to Success
• Check how much it costs to run!
• Blog post on this stuff perhaps?

• Make the word match case-insensitive
• Make the word match only for words in the body
• Allow a list of words to search for
• Can you set up the log metric & stackdriver alert via an API?

You need either docker or python on your local machine - both are easy to install on most common OSes.

If using python directly, pipenv install --dev from the root directory.

There is a wrapper script (./go in bash) to make this easier (Note: CI does not currently use this):

• ./go run- run go locally without building
• ./go test - run unit tests and benchmarks
• ./go build - builds docker image locally and runs smoke tests
• ./go watch-tests - to run pytest continously in the CLI - helpful when developing

1. Enable the API in your GCP project with gcloud services enable run.googleapis.com
2. Come up with a gcloud run deploy command - see the deploy function in ./go for what this ended up being!
3. When switching to CI, the Service Account needs the Cloud Run Admin and Service Account User roles to successfully use gcloud run deploy
4. When authentication is turned on, this command can allow you to grant yourself access to the API: gcloud run services add-iam-policy-binding ${SERVICE_NAME} --member='user:<your-gcp-email-address>' --role='roles/run.invoker'

• I set the PORT in the Dockerfile to 8080, which is the Cloud Run default. Solutions proposed by Google involved hacking about with my Dockerfile, which I wasn't wild about - I don't think $PORT should be a mandatory env variable

• Try out Cloud Build to auto-deploy to it
• Give it a nicer hostname
