개발 및 프로덕션 인프라에 Postgres 추가

prod와 dev infra에 대한 데이터베이스 설정은 동일하며 dev infra에 대해서만 설명합니다.

업데이트 스크립트

도커/dev/docker-compose-up.sh

#!/bin/bash
#export UID=$(id -u)
#export GID=$(id -g)
export CURRENT_UID=$(id -u):$(id -g)
docker volume create --name=kaufman-bot-postgres-volume --label=kaufman-bot-postgres-volume
docker-compose -f ./docker/dev/docker-compose.yml --compatibility up -d

드롭 볼륨이 있는 두 번째 다운 스크립트 추가

도커/dev/docker-compose-clean-down.sh

#!/bin/bash
#export UID=$(id -u)
#export GID=$(id -g)
export CURRENT_UID=$(id -u):$(id -g) 
docker-compose -f ./docker/dev/docker-compose.yml down
docker volume rm kaufman-bot-postgres-volume --force

prod infra의 경우 다른 폴더에서만 같은 작업을 수행합니다.

package.json에 새 스크립트 추가

이제 ssh를 통해 Ubuntu의 서버에 연결하고 postgres 작업을 설정합니다.
