Build Docker container for Gatsby.
docker build -t print-agenda .
Run the container and start the development server listening on 0.0.0.0 (since requests into the container will not be coming from localhost).
docker run --rm -it -p 8000:8000 print-agenda gatsby develop -H 0.0.0.0
Point your browser to http://DOCKER_IP:8000/ (most commonly http://localhost:8000/) to hit the development server.
Make sure you have Node and Yarn installed. Then, install the gatsby app and dependencies.
yarn global add gatsby-cli
yarn install
Then, start the development server.
gatsby develop
