Docker DB

1. 네트워크 생성 (컨테이너 간 통신 위해)

docker network create wp-net

---

2. DB 컨테이너 생성 (MariaDB)

docker run -d \\
  --name ***wp-db*** \\
  
  --network wp-net \\
  
  -e MYSQL_ROOT_PASSWORD=rootpw \\

  -e MYSQL_USER=wpuser \\
  -e MYSQL_PASSWORD=wppw \\
  -e MYSQL_DATABASE=wordpress \\
  
  -v wp-db-data:/var/lib/mysql \\
  mariadb:latest

이 컨테이너는 wordpress라는 데이터베이스를 미리 생성하고,

wpuser / wppw로 접속 가능하게 설정함.

---

3. WordPress 컨테이너 생성 (Apache + PHP 내장)

docker run -d \\
  --name wordpress \\
  
  --network wp-net \\
  
  -e WORDPRESS_DB_HOST=**wp-db**:3306 \\
  -e WORDPRESS_DB_USER=wpuser \\
  -e WORDPRESS_DB_PASSWORD=wppw \\
  -e WORDPRESS_DB_NAME=wordpress \\
  
  -p 8080:80 \\
  -v wp-html:/var/www/html \\
  wordpress:latest

브라우저에서 http://localhost:8080 접속하면 설치 화면 나옴

docker-compose up -d

 

 

 

 

docker exec -it mynginx bash

1. 파일 내용 확인

docker inspect mynginx | less

ESC -> :/[찾을 내용]

docker inspect mynginx | grep -A 10 '"Mounts"' | grep -E '"Source"|"Destination"'

docker inspect mynginx | jq '.[0].Mounts'

docker inspect mynginx | awk '/Mounts/,/]/'
awk '/시작/,/끝/'
