- reactjs-webapp-sample
Back-End Projects

Install

Perform the following steps:

Install Docker in this command.
```
yum install docker-ce
```
Install Docker Compose.

Starting Container

Perform the following steps:

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
```

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
