How to setup nextcloud simply on k8s cluster

How to setup nextcloud simply on k8s cluster

1. Nextcloud

• NextCloud는 open source이며, 파일 저장 및 공유 서비스를 포함한 업무 관련 기능 (ex. 일정 관리, 문서 작업)들을 제공하는 솔루션으로 dropbox 및 google drive의 대체재로 많이 사용되고 있음
• Authentication 및 웹 인터페이스를 기본적으로 제공해주고 있어서, 보다 안전하고 편리하게 데이터를 관리할 수 있다는 장점이 있음

2. k8s yaml file

• 아래 yaml 파일에는 Secret을 사용하지 않았지만, Secret을 만들어서 사용하는 것을 권장

        volumeMounts:
        - mountPath: /var/www/html
          name: tmax-nextcloud-volume
          subPath: nextcloud
        env:

        volumeMounts:
        - mountPath: /var/lib/mysql
          name: tmax-nextcloud-volume
          subPath: db
        env:
        - name: MYSQL_ROOT_PASSWORD
          value: 1234
        - name: MYSQL_PASSWORD

      volumes:
      - name: tmax-nextcloud-volume
        persistentVolumeClaim:
          claimName: tmax-nextcloud-pvc

• Secret을 사용할 경우

apiVersion: v1
kind: Secret
metadata:
  name: tmax-nextcloud-secret
  namespace: tmaxos-infra
type: Opaque
stringData:
  MYSQL_ROOT_PASSWORD: 1234
  MYSQL_PASSWORD: 1234
  MYSQL_DATABASE: nextcloud
  MYSQL_USER: nextcloud
  MYSQL_HOST: 127.0.0.1

• Secret을 사용할 경우 Deployment의 env를 아래와 같이 수정

...
env
  - name: MYSQL_PASSWORD
    valueFrom:
      secretKeyRef:
        name: tmax-nextcloud-secret
        key: MYSQL_PASSWORD
...

3. Access nextcloud through browser

$ http://{ip address}
# ex) http://localhost

4. Create Admin account

• 초기화면에서 계정 생성

5. WebDAV를 통한 파일 업로드 방법

• 파일-> 설정-> WebDAV Address 확인-> curl command를 이용하여 업로드

$ curl --user '{ID}:{Password}' -T "{업로드할 파일}" "{WebDAV Address}/{하위폴더}/{파일이름}"

• 직접 mount를 해서 파일을 업로드하는 방법은 아래 [Accessing Nextcloud files using WebDAV] link 참고
