    How to Use Docker with Vapor Server-Side Swift on Local Development

    I wrote about How to deploy Vapor App(Server-Side-Swift) to the AWS

    This post is about setting on a local server using Docker. (Before you read this post, I highly recommend Server Side Swift – Vapor book.)

     

    Step 1. Create local.Dockerfile

    Look at the last command.

    CMD [“serve”, “–env”, “local”, “–hostname”, “0.0.0.0”, “–port”, “8080”]

    <- I set —env local.

    # Build image
FROM --platform=linux/x86-64 swift:5.5-focal as build

RUN apt-get update -y \
    && apt-get install -y libsqlite3-dev

WORKDIR /build

COPY . .

RUN swift build \
    --enable-test-discovery \
    -c release \
    -Xswiftc -g


# Run image
FROM --platform=linux/x86-64 swift:5.5-focal-slim

RUN useradd --user-group --create-home --home-dir /app vapor

WORKDIR /app

COPY --from=build --chown=vapor:vapor /build/.build/release /app
COPY --from=build --chown=vapor:vapor /build/Public /app/Public

RUN echo "DB_NAME=${AWS_RDS_DB}" >> .env.development

USER vapor

EXPOSE 8080

ENTRYPOINT ["./Run"]
CMD ["serve", "--env", "local", "--hostname", "0.0.0.0", "--port", "8080"]

     

    Step 2. local-docker-compose.yml

    version: '3.7'
services:
  travelcrumb-beta:
    depends_on:
      - postgres
    build:
      context: .
      args:
        AWS_RDS_HOST: postgres
        AWS_RDS_PORT: 5432
        AWS_RDS_USER: shawn
        AWS_RDS_PASS: 1234
        AWS_RDS_DB: test_db
        SIWA_ID: xxxx.xxx.xxx
        SIWA_REDIRECT_URL: localhost:8080
        SIWA_JWK_ID: xxxxx
        SIWA_PRIVATE_KEY: xxxx
        SIWA_TEAM_ID: xxxx
        SIWA_APP_BUNDLE_ID: xxxxx
      dockerfile: local.Dockerfile
    ports:
      - '8080:8080'

  postgres:
    image: postgres
    environment:
      POSTGRES_USER: shawn
      POSTGRES_PASSWORD: 1234
      POSTGRES_DB: test_db

  start_dependencies:
    image: dadarek/wait-for-dependencies
    depends_on:
      - postgres
    command: postgres:5432

     

    Step 3. local.sh 

    #!/bin/bash
echo "🐕 Build Docker"
docker-compose -f local-docker-compose.yml build
echo "🐕 Start dependencies"
docker-compose -f local-docker-compose.yml run --rm
echo "🐕 Start Vapor App"
docker-compose -f local-docker-compose.yml up travelcrumb-beta

     

    Step 4. sh local.sh

    Now you can set up all you need to install for running the Vapor server on your local machine. Without Docker, You have to run and stop DB every time when you run a server on your local machine.
