지금부터 살펴볼 내용은 Kubernetes Helm Package Manage입니다. Helm을 통해 애플리케이션을 배포하고, 원격지에 있는 chart repository를 관리할 수 있습니다.
지난 시간까지 Kubernetes의 다양한 Component들을 설치하고 구성하는 과정과 이를 간편히 진행할 수 있도록 ShellScript를 통해 원스탭 부트 과정까지 살펴보았습니다.
이전 포스팅은 아래를 참고해 주시기 바랍니다.

Helm 구조
Helm은 Client - Server 구조로 구성되어 있으며, Client를 위한 Helm Client, Server를 위한 Helm tiller로 구성되어 있습니다.
또한 Client가 요구하는 애플리케이션의 구성요소들을 정의하고 설정하는 모듈을 Helm Chart라고하며, 마지막으로 이를 Kubernetes 위에 배포하는 과정을 Helm Release라고 합니다.
Helm Client가 애플리케이션을 Release 하는 과정을 살펴보자면 다음과 같습니다.
1) 사용자는 애플리케이션을 배포하기위해 Helm Chart를 정의합니다.
2) 사용자가 Chart를 Release하기 위해 helm install을 실행하면, Helm Client는 gRPC 프로토콜을 통해 Helm Tiller와 통신하며 Chart를 전송합니다.
3) Helm Tiller는 받은 Chart를 재해석하여 Manifest 파일을 생성합니다.
4) 이를 기반으로 Kubernetes에 배포를 수행합니다.
Helm 설치
먼저 Helm을 설치해 보도록 하겠습니다. Helm을 설치하기 위해서는 Kubernetes Cluster 환경이 구성되어 있어야 합니다.
Kubernetes Cluster 환경을 구축하기 위해서는 앞서 살펴본 포스팅 글을 참고하세요.
1) Helm 설치
먼저 Helm 설치를 위한 get_helm.sh 파일을 받아 설치를 진행합니다.
[root@kubemaster kubernetes_onestepboot]# curl https://raw.githubusercontent.com/kubernetes/helm/master/scripts/get | bash
% Total % Received % Xferd Average Speed Time Time Time Current

Preparing to install helm and tiller into /usr/local/bin
helm installed into /usr/local/bin/helm
tiller installed into /usr/local/bin/tiller
Run 'helm init' to configure helm.
[root@kubemaster kubernetes_onestepboot]#설치는 기본 다음 경로에 진행됩니다.
[root@kubemaster kubernetes_onestepboot]# ls -la /usr/local/bin
total 82700

-rwxr-xr-x. 1 root root 42864160 Sep 15 23:29 tiller
[root@kubemaster kubernetes_onestepboot]#
2) Helm Initialize
Helm 설치가 완료되면 server side helm 모듈인 tiller를 구성하고 helm init 명령어로 helm을 Kubernetes Cluster에 등록합니다.
[root@kubemaster kubernetes_onestepboot]# kubectl --namespace kube-system create serviceaccount tiller
serviceaccount/tiller created
[root@kubemaster kubernetes_onestepboot]# kubectl create clusterrolebinding tiller --clusterrole cluster-admin --serviceaccount=kube-system:tiller
clusterrolebinding.rbac.authorization.k8s.io/tiller created
[root@kubemaster kubernetes_onestepboot]# helm init --service-account tiller --wait

Adding local repo with URL: http://127.0.0.1:8879/charts
$HELM_HOME has been configured at /root/.helm.
Tiller (the Helm server-side component) has been installed into your Kubernetes Cluster.
Please note: by default, Tiller is deployed with an insecure 'allow unauthenticated users' policy.
To prevent this, run `helm init` with the --tiller-tls-verify flag.
For more information on securing your installation see: https://docs.helm.sh/using_helm/#securing-your-helm-installation
[root@kubemaster kubernetes_onestepboot]# Helm의 서버인 tiller의 service account를 생성하고 해당 service account에 클러스터를 관리할 수 있는 권한을 부여합니다.
3) Helm Chart 확인
repository update 및 list를 확인합니다.
[root@kubemaster kubernetes_onestepboot]# helm repo update

[root@kubemaster kubernetes_onestepboot]# 나만의 Helm Chart 만들기
앞선 포스팅에서 생성한 Github Pages를 활용한 Helm Chart를 구성하는 방법에 대해 알아보겠습니다.
1) Github Repository 생성
helm chart를 저장할 Repository를 생성합니다. 위와 같이 helm-chart-repo라는 Github Repository를 생성하였습니다.
2) 생성한 Repository Github Page 설정
앞선 포스팅에서 생성한 Github Page를 활용한 Helm Repository를 posting 하는 방법에 대해 살펴보겠습니다.
Github Pages 구성 과정은 다음을 참고해 주세요.
[Container Management] Github Pages 생성 및 관리
생성한 helm-chart-repo repository를 Github Pages에 연결하는 과정부터 살펴보겠습니다.
https://github.com/sonnaraon/helm-chart-repo → Settings → GitHub Pages → Source → master branch
3) Helm Repository 블로그 접속
master branch 선택이 완료되면 해당 Repository는 다음과 같이 접속이 가능해 집니다.
https://[signed_in_account].github.io/project_name
저의 경우 https://sonnaraon.github.io/project_name로 접속이 가능합니다.
현재 helm chart repo로 readme.md이 추가되어 있어 위와 같은 화면이 출력됩니다.
Helm chart 생성 및 Github에 추가
먼저 Github Project를 pull 받아 Helm chart를 신규로 생성하고 적용하는 과정에 대해 살펴보겠습니다.
git 관련된 포스팅은 다수 다루었으므로 별도의 설명 없이 명령어를 나열하도록 하겠습니다.
1) Github pull
[root@kubemaster helm]# git init
Reinitialized existing Git repository in /root/helm/.git/
[root@kubemaster helm]# git remote add origin https://github.com/sonnaraon/helm-chart-repo.git
[root@kubemaster helm]# git pull https://github.com/sonnaraon/helm-chart-repo.git
remote: Enumerating objects: 3, done.
remote: Counting objects: 100% (3/3), done.
remote: Total 3 (delta 0), reused 0 (delta 0), pack-reused 0
Unpacking objects: 100% (3/3), done.
From https://github.com/sonnaraon/helm-chart-repo
* branch HEAD -> FETCH_HEAD
[root@kubemaster helm]# ls
README.md
[root@kubemaster helm]#2) demo project helm chart 생성
[root@kubemaster helm]# mkdir stable
[root@kubemaster helm]# helm create demo
Creating demo
[root@kubemaster helm]# helm package demo
Successfully packaged chart and saved it to: /root/helm/demo-0.1.0.tgz
[root@kubemaster helm]# mv demo-0.1.0.tgz stable/
[root@kubemaster helm]# 먼저 stable 디렉토리를 생성하여 생성한 charts를 저장할 수 있도록 구성합니다.
다음으로 helm create 명령어로 demo chart를 생성합니다. helm package 명령어로 생성한 chart를 패키지로 묶습니다.
마지막으로 해당 package를 생성한 stable 디렉토리로 이동합니다.
3) Github Pages와 연동할 index 생성
[root@kubemaster helm]# helm repo index stable --url https://sonnaraon.github.io/helm-chart-repo/stable
[root@kubemaster helm]#다음으로 위와 같이 index를 생성하여 git repository와 github pages와 연결고리를 생성합니다.
생성 방법은
helm repo index [INDEX_FILE_PATH] --url [CHART_REPO_URL/INDEX_FILE_NAME]
즉 본 샘플에서는 helm repo index stable --url https://sonnaraon.github.io/helm-chart-repo/stable와 같은 형태로 인덱스를 생성하게 됩니다.
4) Github에 push
[root@kubemaster helm]# git add .
[root@kubemaster helm]# git commit -m "demo chart add"
[master 7b56b59] demo chart add
Committer: root <root@kubemaster.skbroadband>

[root@kubemaster helm]#위와 같이 github에 적용한 파일을 push합니다.
Github Pages 확인 및 Helm Chart 다운로드
1) Github Pages 확인
먼저 github pages에서 index로 추가한 demo chart가 추가되었는지 확인해 보도록 하겠습니다.
확인 URL은 https://[signed_in_account].github.io/[repository_name]/stable/index.yaml 입니다.
저의 경우 https://sonnaraon.github.io/helm-chart-repo/stable/index.yaml로 호출합니다.
위와 같이 해당 stable에는 demo-0.1.0.tgz chart를 제공하고 있습니다.
2) Helm Chart 다운로드
다운로드 받는 방법은 다양합니다.
[직접 URL을 치고 다운로드 받는 방법]
[wget으로 다운로드 받는 방법]
[root@kubemaster helm]# wget https://sonnaraon.github.io/helm-chart-repo/stable/demo-0.1.0.tgz

[root@kubemaster helm]#[helm repo 명령어로 다운로드 받는 방법]
마지막으로 helm repo 명령어로 다운로드 받는 방법입니다.
지금까지 추가한 helm charts repository를 다음과 같이 helm repo에 추가합니다.
3) Helm repo 관리
[root@kubemaster helm]# helm repo add helm-chart-repo https://sonnaraon.github.io/helm-chart-repo/stable
"helm-chart-repo" has been added to your repositories
[root@kubemaster helm]# helm repo list | grep sonnaraon
helm-chart-repo https://sonnaraon.github.io/helm-chart-repo/stable
[root@kubemaster helm]# helm search helm-chart-repo
NAME CHART VERSION APP VERSION DESCRIPTION
helm-chart-repo/demo 0.1.0 1.0 A Helm chart for Kubernetes
[root@kubemaster helm]#위와 같이 추가한 helm repository를 local에 추가할 수 있습니다.
- helm repo add [helm_chart_name] [helm_chart_url]
- helm repo list
- helm search [helm_chart_name]
helm repo list로 추가된 리포지토리를 확인할 수 있습니다.
helm search로 chart 정보를 확인할 수 있습니다.
4) Helm install
마지막으로 살펴볼 내용은 Helm으로 추가한 Repository를 적용하는 방법입니다.
Helm으로 demo 패키지를 install 하기 위해서는 당연히 Kubernetes가 먼저 기동되어 있어야 합니다.
[root@kubemaster helm]# helm install helm-chart-repo/demo
NAME: kubemaster
LAST DEPLOYED: xxx
NAMESPACE: default
STATUS: DEPLOYED
RESOURCES:
==> v1beta2/Deployment
NAME AGE
kubemaster-demo 0s
==> v1/Pod(related)
NAME READY STATUS RESTARTS AGE
kubemaster-demo-54dd9c69f8-b77dz 0/1 ContainerCreating 0 0s
==> v1/Service
NAME AGE
kubemaster-demo 0s
NOTES:
1. Get the application URL by running these commands:
export POD_NAME=$(kubectl get pods --namespace default -l "app.kubernetes.io/name=demo,app.kubernetes.io/instance=kubemaster" -o jsonpath="{.items[0].metadata.name}")
echo "Visit http://127.0.0.1:8080 to use your application"
kubectl port-forward $POD_NAME 8080:80
[root@kubemaster helm]#이번 시간에는 Helm Chart를 직접 생성하고 자신만의 Repository에 Chart를 저장하여 호출하는 과정을 살펴보았습니다.
이를 활용하여 Gitlab에 적용한다면, 폐쇄망 환경에서도 적용이 가능하지 않을까 싶습니다.
