dusanstevic/servers-0.1.0

Servers-0.1.0

Servers

Application that list servers. Data are fixed and application does not use database as a storage.

Dockerfile contains two runtime stages:

• appServerRuntime - Spring Boot application server that provides REST API.
• appWebServerRuntime - Spring Boot application that provides REST API and contains Angular front-end web application

BuildKit is used for building container images.

In order to build appServerRuntime image run the following command (Dockerfile has to be in current working directory):

DOCKER_BUILDKIT=1 docker build --target appServerRuntime -t danijelradakovic/servers:0.1.0 .

In order to build appWebServerRuntime image run the following command (Dockerfile has to be in current working directory):

DOCKER_BUILDKIT=1 docker build --target appWebServerRuntime -t danijelradakovic/servers:0.1.0-web .

appServerRuntime Instructions (Spring Boot REST API)

Start Docker Daemon: If you're using Docker for Windows, Then simply start the desktop app installed in:

C:\Program Files\Docker\Docker\Docker Desktop.exe

Position yourself in the folder where dockerfile is

cd DOCKERFILE_PATH

Create Docker image from Dockerfile with Docker BuildKit (Generating .jar binary file; .jar file is not already generated, so we need to map source code to .jar file)

docker image build --target DOCKERFILE_STAGE -t DOCKER_HUB_USERNAME/IMAGE_NAME:VERSION DOCKERFILE_PATH

docker image build --target appServerRuntime -t danijelradakovic/servers:0.1.0 .

Creates and runs Docker containers (Interactive mode; Container port forwarding)

docker run -MODE --name CONTAINER_NAME -p HOST_PORT:CONTAINER_PORT IMAGE_NAME

docker run -MODE --name CONTAINER_NAME -p PUBLISHED_PORT:EXPOSED_PORT IMAGE_NAME

docker run -it --name servers-0.1.0 -p 9000:8080 danijelradakovic/servers:0.1.0
