# With Docker
|
|
|
|
## How to use
|
|
|
|
### Using `create-next-app`
|
|
|
|
Execute [`create-next-app`](https://github.com/segmentio/create-next-app) with [Yarn](https://yarnpkg.com/lang/en/docs/cli/create/) or [npx](https://github.com/zkat/npx#readme) to bootstrap the example:
|
|
|
|
```bash
|
|
npx create-next-app --example with-docker with-docker-app
|
|
# or
|
|
yarn create next-app --example with-docker with-docker-app
|
|
```
|
|
|
|
### Download manually
|
|
|
|
Download the example [or clone the repo](https://github.com/zeit/next.js):
|
|
|
|
```bash
|
|
curl https://codeload.github.com/zeit/next.js/tar.gz/canary | tar -xz --strip=2 next.js-canary/examples/with-docker
|
|
cd with-docker
|
|
```
|
|
|
|
Build it with docker:
|
|
|
|
```bash
|
|
# build
|
|
docker build -t next-app .
|
|
# or, use multi-stage builds to build a smaller docker image
|
|
docker build -t next-app -f ./Dockerfile.multistage .
|
|
```
|
|
|
|
Run it:
|
|
|
|
```bash
|
|
docker run --rm -it \
|
|
-p 3000:3000 \
|
|
-e "API_URL=https://example.com" \
|
|
next-app
|
|
```
|
|
|
|
Deploy it to the cloud with [now](https://zeit.co/now) ([download](https://zeit.co/download))
|
|
|
|
```bash
|
|
now --docker -e API_URL="https://example.com"
|
|
```
|
|
|
|
>*Note: Multi-stage only works in OSS plan. [\[#962\]](https://github.com/zeit/now-cli/issues/962#issuecomment-383860104)*
|
|
|
|
## The idea behind the example
|
|
|
|
This example show how to set custom environment variables for your __docker application__ at runtime.
|
|
|
|
The `dockerfile` is the simplest way to run Next.js app in docker, and the size of output image is `173MB`. However, for an even smaller build, you can do multi-stage builds with `dockerfile.multistage`. The size of output image is `85MB`.
