👀 Epilogue
- 역시나 험난한 트러블 슈팅기
- 도커가 없다고 하는 거 같아요..
⚡ Leggo
- 플러그인 설치
- Docker
- Docker Pipeline
- 실패..
- uname -a 를 통해 OS 정보 확인

- 도커 설치 스크립트 추가
sudo apt-get update
sudo apt-get install docker.io
sudo ln -sf /usr/bin/docker.io /usr/local/bin/docker
- agent pod에서 sudo: not found 문제로 실패
- 해결책
apt-get update && apt-get -y install sudo
- 이지만 매번 agent pod가 띄워질 때마다 패키지를 업데이트하고 설치하는 것이 빌드 파이프라인에 시간이 많이 소비될 것이 우려됨
- 다른 해결책을 찾다가 저번 Gradle Build에서 Custom Agent를 실패했던 것이 떠올랐다.
- 현재 Agent pod에 도커가 없으니
- ‘Docker Container를 Custom해서 Agent에 넣어주면 Image Build가 되지 않을까’
- 라고 생각하게 되었다.
- Agent Docker Container
spec:
containers:
- name: docker
image: docker:latest
command:
- cat
tty: true
volumeMounts:
- mountPath: /var/run/docker.sock

- Dockerfile
