Running Shiny app on Google Cloud Run

EDIT: it is probably outdated as Google Cloudrun now supports websocket.

PROJECTID=$(gcloud config get-value project)

Build the image locally and push to Google registry

docker build . -t gcr.io/$PROJECTID/shinyrun
# optional, test locally
# docker run --rm -p 8080:8080 gcr.io/$PROJECTID/shinyrun:latest
gcloud auth configure-docker
docker push gcr.io/$PROJECTID/shinyrun

Alternatively, ultilize Googld Builds to build image

gcloud builds submit --tag gcr.io/$PROJECTID/shinyrun

Deploy to Google Cloud Run

gcloud run deploy --image gcr.io/$PROJECTID/shinyrun --platform managed --max-instances 1
# for project with large memory need
# gcloud run deploy --image gcr.io/$PROJECTID/shinyrun --platform managed --max-instances 1 --memory 1G
