Provide a Dockerfile

[juliangorge]

Hi Kiranism,

Thank you for this amazing repo! I’m using it in a couple of projects, and it’s been incredibly helpful.

Would you consider adding a Dockerfile? I tried using the official Next.js Dockerfile, but deployment takes an extremely long time (around 30 minutes on a VPS).

Best regards!

Unfortunately NextJS can be a bit annoying for Docker.
To reduce the build time problem, you can build on your machine, or on a server (like Github Actions) and upload to a docker registry.

If you want a ready-made Dockerfile, I use this one:

!! (you will have problems with it if you are using NEXT_PUBLIC variables)

FROM node:21-alpine AS base

RUN apk add --no-cache libc6-compat

FROM base AS dev

WORKDIR /usr/app

COPY package*.json ./

RUN npm ci

FROM base AS build

WORKDIR /usr/app

ENV NODE_ENV="production"

COPY --from=dev /usr/app/package*.json ./
COPY --from=dev /usr/app/node_modules ./node_modules

COPY . .

RUN rm -rf *.env

RUN npm run build

RUN npm prune --production

FROM base AS prod

WORKDIR /usr/app

COPY --from=build /usr/app/.next ./.next
COPY --from=build /usr/app/node_modules ./node_modules
COPY --from=build /usr/app/package*.json ./

CMD ["npm", "run", "start"]
