How to Dockerize A Svelte App

By default, Svelte loads the app from the local host. We need to map ports and bind the container.

• We can create Dockerfile in our app directory:

FROM node:14-alpine

# install dependencies
WORKDIR /app
COPY rollup.config.js ./
COPY package*.json ./
RUN npm install

COPY ./src ./src
COPY ./public ./public
RUN npm run-script build

EXPOSE 5000
ENV HOST=0.0.0.0
CMD [ "npm", "start" ]

• Build a local image:

docker build -t myapp .

• Finally, run it:

docker run -p 5000:5000 myapp
