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

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

1. Create a Dockerfile with the following content:

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.

1. Create a Dockerfile with the following content:

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.

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:

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.
