docker-webapp-sample

Preface

This project is a sample for running the following web application on docker containers.

• Front-End Projects
  • vuejs-webapp-sample
  • reactjs-webapp-sample
• Back-End Projects
  • springboot-webapp-sample
  • rails-webapp-sample
  • aspnetcore-webapp-sample
  • go-webapp-sample

Install

Perform the following steps:

1. Install Docker in this command.

   yum install docker-ce

2. Install Docker Compose.

Starting Container

Perform the following steps:

1. Build the docker-compose.yml in Docker Compose. Set a yml file with the -f option. For Spring Boot, set docker-compose_springboot.yml.

   docker-compose -f [File Name] build --no-cache

   ex)

   docker-compose -f docker-compose_springboot.yml build --no-cache

2. Start containers in Docker Compose.

   docker-compose -f [File Name] up -d

   ex)

   docker-compose -f docker-compose_springboot.yml up -d

Change web container

In this sample, you can change the web container from Vue.js to React.js. To change the container, edit the following source:

Before

services:
  web:
    build: ./web/vue
    container_name: web-server

After

services:
  web:
    build: ./web/react
    container_name: web-server

Access to container

Start a bash session on a running container in the following command.

• Web Container

  docker exec -it web-server /bin/bash

• Application Container

  docker exec -it app-server /bin/sh
  docker logs -f app-server

• Database Container

  docker exec -it db-server psql -U testusr testdb
  docker exec -it db-server /bin/sh
  pg_dump --inserts -U testusr testdb

  Show tables and select stored datas.

  # show tables
  \dt;
  # select BOOK table
  select * from "BOOK";
  # exit
  \q

Stopping Container

This command can stop a running container.

docker-compose -f [File Name] stop

ex)

docker-compose -f docker-compose_springboot.yml stop

Also, the next command can delete the stopped container.

docker-compose -f [File Name] rm

ex)

docker-compose -f docker-compose_springboot.yml rm
