To install the env, run pipenv install --dev
To initialize the git hooks, run pipenv run pre-commit install
If there are file that were committed before adding the git hooks, run pipenv run pre-commit run --all-files
To run tests, run pipenv run pytest --cov-config=.coveragerc --cov=resc

Copy demo.env to .env: cp demo.env .env
Change MAPBOX_TOKEN in .env to your Mapbox Token
Run the app locally in dev mode with pipenv run python app/app.py

Note: there can only be one app engine application per project.
Create the App Engine App: gcloud app create
Deploy with gcloud app deploy --appyaml=app.yml

To select you account and project, run gcloud init
Set a default region.
Set an APP_NAME environmental variable with: export APP_NAME=my-app To get and save your project id, run export PROJECT=$(gcloud config get-value project)
To get the GCR tag, run export GCR_TAG=gcr.io/$PROJECT/$APP_NAME
To submit the build to GCP Cloud Build, run gcloud builds submit --tag $GCR_TAG
To see the GCR tag, run echo $GCR_TAG

Go to "Compute Engine" in the GCP UI and select "CREATE INSTANCE".
In the options select the checkbox "Deploy a container image to this VM instance."
Paste in the GCR tag in the "Container Image" field.
Click "Advanced container options".
Add the Mapbox token as an environment variables.
Select "Allow HTTP traffic" for a public deployment.

Run:

gcloud compute instances create-with-container $APP_NAME \
  --machine-type e2-small \
  --container-image $GCR_TAG \
  --tags dash-server \
  --container-env-file .env

Run:

gcloud compute firewall-rules create dash-allow-http \
  --allow tcp:80 \
  --target-tags dash-server

Go to "Cloud Run" in the GCP console and select "CREATE Service".
Pick a service name and Region.
Select "Deploy one revision from an existing container image" and select the latest image image for "gcr.io/[your project]/[app name]".
Select "Allow all traffic".
Select "Allow unauthenticated invocations". Click "Create".
Click "EDIT & DEPLOY NEW REVISION".
Click "CONTAINER" and change "Container port" to 80. Click "VARIABLES & SECRETS". Click "ADD VARIABLE" and add the variable with the Name "MAPBOX_TOKEN" and the Value as the token.
Click "Deploy".

Environmental variables are a good way to keep our tokens secret and our options configurable.
To set them, copy sample.envrc to .envrc and change the values.
To load .envrc, one could just run .envrc as a shell script, but direnv will make things easier by automatically loading the variable when you enter the directory, once allowed.
To install direnv on a mac running zsh, use brew to install with brew install direnv and hook in into your shell by adding eval "$(direnv hook zsh)" to your .zshrc file.
For other install instructions see: https://direnv.net/.
To allow direnv to load .envrc in a directory run direnv allow.

Run:

gcloud run deploy $APP_NAME --image $GCR_TAG \
   --platform managed \
   --allow-unauthenticated \
   --set-env-vars MAPBOX_TOKEN=$MAPBOX_TOKEN \
   --region us-west1 \
   --port 80

Every deployment option creates a GCR image. Delete with: gcloud container images delete gcr.io/$PROJECT/$APP_NAME

There are some artifacts that are created by GCR. Delete them using gsutil.
If you don't have it installed see: https://cloud.google.com/sdk/docs/install
NOTE: THIS WILL DELETE OTHER ARTIFACTS AS WELL, RUN WITH CARE.
Run:

gsutil rm -r gs://artifacts.$PROJECT.appspot.com && \
gsutil rm -r gs://${PROJECT}_cloudbuild

If you used option 1 to deploy, go to "Compute Engine" in the console and delete the VM that you made.

If you used option 2 to deploy, run: gcloud compute instances delete $APP_NAME

If you used option 3 to deploy, go to "Cloud Run" in the console and delete the service that you made.

If you used option 4 to deploy, run gcloud run services delete $APP_NAME --region us-west1
