Step1 Creating Ktor Project

Create a new project in Ktor Project Generator

note: You can also create a new project in IntelliJ, but it is deprecated because it is obsolete.

Step2 Creating Docker

Dockerfile

Create a Dockerfile in the root folder

# Use the official gradle image to create a build artifact.
FROM gradle:6.7 as builder

# Copy local code to the container image.
COPY build.gradle.kts .
COPY gradle.properties .
COPY src ./src

# Build a release artifact.
RUN gradle installDist

FROM openjdk:8-jdk
EXPOSE 8080:8080
RUN mkdir /app
COPY --from=builder /home/gradle/build/install/gradle /app/
WORKDIR /app/bin
CMD ["./gradle"]

debug

docker build -t my-application .
docker run -p 8080:8080 my-application

docker-compose.yml

Create docker-compose.yml in the root folder

version: '2'
services:
  web:
    build:
      context: ./
      dockerfile: Dockerfile
    ports:
      - 8080:8080

Step3 Docker Build & Run

docker-compose up --build

After booting, accessed http://0.0.0.0:8080/ and saw Hello World!
