SvelteKit Dockerfiles

The following are dockerfiles that could be used to build sveltekit apps images using different adapters.

Table of Contents

• Using Node/Auto Adapter
• Using Bun Adapter
• Using Static Adapter (and nginx)

  Using Node/Auto Adapter

1. Create a Dockerfile with the following content: ```Dockerfile FROM node:alpine

WORKDIR /app COPY package.json ./ RUN npm install

COPY . . RUN npm run build

CMD ["node", "build"]

EXPOSE 3000

2. Build the Docker image:
`docker build -t sveltekit-node ./adapter-node.Dockerfile`

3. Run the Docker container:
`docker run -p 3000:3000 sveltekit-node`
App should now be accessible at `http://localhost:3000`.


### Using Bun Adapter

1. Create a Dockerfile with the following content:
```Dockerfile
FROM oven/bun

WORKDIR /app
COPY package.json package.json
RUN bun install

COPY . .
RUN bun run build

EXPOSE 3000
ENTRYPOINT ["bun", "./build"]

2. Build the Docker image: docker build -t sveltekit-bun ./adapter-bun.Dockerfile

3. Run the Docker container: docker run -p 3000:3000 sveltekit-bun App should now be accessible at http://localhost:3000.

Using Static Adapter (and nginx)

Since static adapter outputs static html/js files/assets, we can use nginx to serve the project. The project is first built using node image, and then uses nginx image to serve the built files... giving a much smaller image size.

1. Create a Dockerfile with the following content: ```Dockerfile FROM node:alpine as build

ADD . /app WORKDIR /app

RUN npm install RUN npm run build

FROM nginx:stable COPY nginx.conf /etc/nginx/conf.d/default.conf COPY --from=build /app/build /usr/share/nginx/html

2. Create an `nginx.conf` file in the same directory as the `Dockerfile` with the following content:

server { listen 80; listen [::]:80; server_name _;

location / {
  root /usr/share/nginx/html;
  try_files $uri $uri/index.html $uri.html /index.html;
}

include mime.types;
types {
    application/javascript js mjs;
}

}

2. Build the Docker image:
`docker build -t sveltekit-static ./adapter-static.Dockerfile`

The image exposes port 80, so to run it on port 3000 locally:
`docker run -p 3000:80 sveltekit-static`
App should now be accessible at `http://localhost:3000`.

Different projects may require different dependencies and dockerization techniques, the above is one of the ways you can achieve this.
