Docker 환경에서 DB 자동 백업이 필요할 때 사용. PostgreSQL, MySQL, MariaDB 지원. /docker-db-backup으로 실행.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Docker DB Backup Skill
Docker Compose 프로젝트에 cron 기반 자동 DB 백업 컨테이너를 추가하는 스킬입니다.
## Skill Description
**Triggers:**
- `/docker-db-backup` — 대화형으로 DB 종류를 확인 후 백업 서비스 추가
- `/docker-db-backup pg` — PostgreSQL 백업 서비스 추가
- `/docker-db-backup mysql` — MySQL/MariaDB 백업 서비스 추가
**생성/수정되는 파일:**
- `{compose-dir}/backup-entrypoint.sh` — 백업 실행 엔트리포인트
- `{compose-dir}/docker-compose.yml` — db-backup 서비스 추가
- `{compose-dir}/.env` — 백업 설정 변수 추가
## Execution Steps
### Step 1: 프로젝트 분석
1. `docker-compose.yml` 위치를 찾는다 (프로젝트 루트 또는 `docker-images/` 등)
2. 기존 DB 서비스를 파악한다:
- `postgres` / `pg` 이미지 → PostgreSQL
- `mysql` / `mariadb` 이미지 → MySQL/MariaDB
3. DB 서비스명, 환경변수명, 포트, 헬스체크 조건을 추출한다
4. 인자가 없으면 사용자에게 DB 종류를 확인한다
### Step 2: backup-entrypoint.sh 생성
**반드시 LF 줄바꿈으로 생성해야 한다.** Windows에서 CRLF로 생성하면 컨테이너에서 깨진다.
생성 후 아래 명령을 실행:
```bash
sed -i 's/\r$//' {compose-dir}/backup-entrypoint.sh
```
#### PostgreSQL 템플릿
```sh
#!/bin/sh
set -e
BACKUP_DIR="${BACKUP_DIR:-/backups}"
RETENTION_DAYS="${RETENTION_DAYS:-7}"
CRON_SCHEDULE="${CRON_SCHEDULE:-0 2 * * *}"
mkdir -p "$BACKUP_DIR"
cat > /usr/local/bin/run-backup.sh << 'SCRIPT'
#!/bin/sh
set -e
BACKUP_DIR="${BACKUP_DIR:-/backups}"
…Read the whole file at its exact version.
How to install
mdr add dannykkh/skill-olympus/docker-db-backup@sha256:6d5c6c485b84bc0aThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
