Repository files navigation

This is a Next.js project bootstrapped with create-next-app.

Build Docker Image

docker build -t nextjs-in-docker .

Run Docker Image

We need to pass an environment variable to the docker run command using -e NEXT_PUBLIC_[VARIABLE_NAME] where [VARAIBLE_NAME] is the name of your variable. You can also use the --env-file flag to specify the .env file.

Passing environment variables via -e:

docker run -p 3000:3000 -e NEXT_PUBLIC_MESSAGE='from docker!' nextjs-in-docker

Passing environment variables via --env-file:

docker run -p 3000:3000 --env-file .env.development nextjs-in-docker

Getting Started

First, run the development server:

npm run dev
# or
yarn dev

Open http://localhost:3000 with your browser to see the result.

You can start editing the page by modifying pages/index.js. The page auto-updates as you edit the file.

API routes can be accessed on http://localhost:3000/api/hello. This endpoint can be edited in pages/api/hello.js.

The pages/api directory is mapped to /api/*. Files in this directory are treated as API routes instead of React pages.

Developing with k8s and HMR

The k8 branch uses Skaffold to build and deploy the app to a kubernetes cluster with hot module reload support.

The tilt branch uses Tilt to build and deploy the app to a kubernetes cluster with hot module reload support.
