설치 환경
- Ubuntu v20.04.1 (Master, Worker node 각각 1대)
- Docker v19.03.13
- Kubernetes v1.19.4
- Chartmuseum v0.14.0
- Minio
- Spinnaker v1.24.1
Chartmuseum 설치
※ ALLOW_OVERWRITE=true 설정을 해주지 않으면, 같은 버전의 helm chart를 push하더라도 overwrite되지 않는다. 기본 false이므로 overwrite가 필요한 경우 반드시 설정해주어야한다.
Docker, On-premise 두가지로 설치해보았고, 한가지를 선택하면 된다. 개인적으로는 저장소는 안정성 측면에서 On-premise로 설치하는 것을 선호하는 편이다.

...Spinnaker 구성
- Halyard 설치 (https://spinnaker.io/docs/setup/install/halyard/)
- halyard에서는 기본적으로 몇가지 디렉터리 및 파일을 볼륨으로 저장하고 있어야한다. 예를 들면, Spinnaker 배포를 위한 /home/spinnaker/.hal 디렉터리, cloud provider 접근을 위한 config 파일 등이 필요하다. 일단 volume 설정을 해놓으면 spinnaker를 배포하면서 필요한 디렉터리들이 volume에 함께 생성되므로 처음부터 해당 파일들을 생성할 필요는 없다.
- 주요 디렉토리 구조
| /home/spinnaker/.hal | config | spinnaker configuration 파일 | ||
| default | profiles | front50-local.yaml | minio는 versioning을 지원하지 않기때문에 versioning false 설정을 위해 생성한 파일 | |
| .kube | config | cloud provider 접근을 위한 config 파일 (파일과 디렉터리 이름은 변경 가능하다) |

halyard 커맨드 hal을 통해 config 설정부터 배포까지 가능하다 (https://spinnaker.io/docs/reference/halyard/commands/)
### 1. halyard 컨테이너 접속
$ kubectl exec -it halyard-0 -n spinnaker -- /bin/bash
bash-5.0$
### 2. Cloud Providers 설정
# Choose Cloud Providers
bash-5.0$ hal config provider kubernetes enable
# account 추가
bash-5.0$ hal config provider kubernetes account add my-k8s-account \
--provider-version v2\
--context $(kubectl config current-context)
# artifacts 사용 enable
bash-5.0$ hal config features edit --artifacts true
### 3. Choose your Environment → Distributed installation
bash-5.0$ hal config deploy edit --type distributed --account-name my-k8s-account
### 4. Choose a Storage Service → Minio
# Minio는 versioning을 지원하지 않으므로, versioning disable
bash-5.0$ mkdir ~/.hal/default/profiles && \
touch ~/.hal/default/profiles/front50-local.yaml
bash-5.0$ vi ~/.hal/default/profiles/front50-local.yaml
bash-5.0$ spinnaker.s3.versioning: false
# storage provider 설정
bash-5.0$ export MINIO_SECRET_KEY=myMinioRootUser
bash-5.0$ export MINIO_ACCESS_KEY=myMinioRootPassword
bash-5.0$ export ENDPOINT=http://minio:9000 # ENDPOINT는 minio 설치 방법에 따라 minio가 설치된 IP가 될 수 있다.
bash-5.0$ echo $MINIO_SECRET_KEY | \
hal config storage s3 edit --endpoint $ENDPOINT \
--access-key-id $MINIO_ACCESS_KEY \
--secret-access-key
# s3 storage provider enable 설정
bash-5.0$ hal config storage edit --type s3
### 5. Configure Helm Artifact Account -> chartmuseum
bash-5.0$ echo myChartmuseumId:myChartmuseumPass > chartmuseumAccount
bash-5.0$ hal config artifact helm enable
bash-5.0$ hal config artifact helm account add my-helm-account \
--username-password-file chartmuseumAccount
### 6. Deploy Spinnaker
# version 선택
bash-5.0$ hal config version edit --version 1.24.1
# spinnaker 배포
bash-5.0$ hal deploy apply
### 7. NodePort로 외부 통신을 열어준다. (실제 운영에서는 ingress를 통해 tls 및 도메인 설정등이 가능하다)
bash-5.0$ kubectl edit svc spin-deck -n spinnaker
...
type: NodePort
ports:
- port: 9000
protocol: TCP
targetPort: 9000
nodePort: 30300
bash-5.0$ kubectl edit svc spin-gate -n spinnaker
...
type: NodePort
ports:
- port: 8084
protocol: TCP
targetPort: 8084
nodePort: 30400
bash-5.0$ hal config security ui edit --override-base-url "http://IP address:30300"
bash-5.0$ hal config security api edit --override-base-url "http://IP address:30400"
bash-5.0$ hal deploy apply
$ kubectl get po -n spinnaker
