Dockerfile Template (React, Express, Vue, Nest, Angular, GoFiber, Svelte, Django, Laravel, ASP.NET Core, Kotlin, Deno)

These are docker template for deploying common applications (either using Kubernetes, Nomad, or locally using docker-compose), this post are copied mostly from scalablescripts youtube channel and docker docs, the gist for nginx config are here.


ReactJS

FROM node:15.4 as build1
WORKDIR /app1
COPY package+.json .
RUN npm install
COPY . .
RUN npm run build

FROM nginx:1.19
COPY ./nginx.conf /etc/nginx/nginx.conf
COPY --from=build1 /app1/build /usr/share/nginx/html

To build it, use docker build -t react1 .
To run it, use docker run -p 8001:80 react1


ExpressJS

FROM node:15.4 
WORKDIR /app
COPY package+.json .
RUN npm install
COPY . .
CMD node index.js


VueJS

FROM node:15.4 as build1
WORKDIR /app1
COPY package+.json .
RUN npm install
COPY . .
RUN npm run build

FROM nginx:1.19
COPY ./nginx.conf /etc/nginx/nginx.conf
COPY --from=build1 /app1/dist /usr/share/nginx/html

The only different thing from react is the build directory not build/ but dist/.


NestJS 

FROM node:15.4 as build1
WORKDIR /app1
COPY package+.json .
RUN npm install
COPY . .
RUN npm run build

FROM node:15.4
WORKDIR /app
COPY package.json .
RUN npm install --only=production
COPY --from=build1 /app1/dist ./dist
CMD npm run start:prod


AngularJS

FROM node:15.4 as build1
WORKDIR /app1
COPY package+.json .
RUN npm install
COPY . .
RUN npm run build --prod

FROM nginx:1.19
COPY ./nginx.conf /etc/nginx/nginx.conf
COPY --from=build1 /app1/dist/PROJECT_NAME /usr/share/nginx/html


Fiber (Golang)

FROM golang:1.16-alpine as build1
WORKDIR /app1
COPY go.mod .
COPY go.sum .
RUN go mod download
COPY . .
RUN CGO_ENABLED=0 GOOS=linux go build -o app1.exe

FROM alpine:latest
RUN apk --no-cache add ca-certificates
WORKDIR /
COPY --from=build1 /app1/app1.exe .
CMD ./app1.exe

You don't need COPY go.mod to go mod download step if you have vendor/ directory to /go/pkg/mod, you can reuse it instead of redownloading whole dependencies (this can really faster things up on the CI/CD pipeline, especially if you live on 3rd world country). The ca-certificates only needed if you need to hit https endpoints, if you don't then you can skip that step.


Svelte

FROM node:15.4 as build1
WORKDIR /app1
COPY package+.json .
RUN npm install
COPY . .
RUN npm run build

FROM nginx:1.19
COPY ./nginx.conf /etc/nginx/nginx.conf
COPY --from=build1 /app1/public /usr/share/nginx/html


Django

FROM python:3.9-alpine as build1
ENV PYTHONUNBUFFERED 1
WORKDIR /app1
COPY requirements.txt .
CMD pip install -r requirements.txt
COPY . .
CMD python manage.py runserver 0.0.0.0:80


Laravel

FROM php:7.4-fpm
RUN apt-get update && apt-get install -y git curl libpng-dev libonig-dev libxml2-dev zip unzip
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer
RUN docker-php-ext-install pdo_mysql mbstring
WORKDIR /app1
COPY composer.json .
RUN composer install --no-scripts
COPY . .
CMD php artisan serve --host=0.0.0.0 --port=80


ASP.NET Core

FROM mcr.microsoft.com/dotnet/sdk:5.0 as build1
WORKDIR app1
COPY *.csproj .
CMD dotnet restore
COPY . .
RUN dotnet publish -c Release -o out

FROM mcr.microsoft.com/dotnet/aspnet
WORKDIR /app
COPY --from=build1 /app1/out .
ENTRYPOINT ["dotnet", "PROJECT_NAME.dll"]


Kotlin

FROM gradle:7-jdk8 as build1
WORKDIR /app1
COPY . .
RUN ./gradlew build --stacktrace

FROM openjdk
WORKDIR /app
EXPOSE 80
COPY --from=build1 /app/build/libs/PROJECT_NAME-VERSION-SNAPSHOT.jar .
CMD java -jar PROJECT_NAME-VERSION-SNAPSHOT.jar


Deno

FROM denoland/deno:1.11.0
WORKDIR /app1
COPY . .
RUN ["--run","--allow-net","app.ts"]


Deployment

For deployment you can use AWS (elastic container registry and elastic container instance or elastic container service with fargate), Azure (azure container registry and azure container instance), GoogleCloud (upload to container registry and google cloud run), or just upload it to docker registry then pull it on the server.
