Hi, on page 361 the author says that we also need to rebuild the webpack image after adding the gem cache and bundling in the app container itself.
Because the web/app service depends on webpack-dev-server, couldn’t we just use the same image with:
web
image: app_webpack_dev_server
Since it will be built before can’t we just reuse it?
“There’s one final complication: our webpack_dev_server service. Since this uses the same Dockerfile as our web service, we also need to rebuild its image”
