Chartmuseum

# Chartmuseum
helm3默认不再提供仓库功能，需要通过官方提供的工具chartmuseum来实现。

## 使用k8s部署
- k8s版本: v1.22.5+k3s1
- yaml配置文件

```yaml
apiVersion: v1
kind: Service
metadata:
  labels:
    production: chartmuseum
  name: chartmuseum
  namespace: default
spec:
  ports:
    - port: 80
      targetPort: 8080
      name: chartmuseum
  selector:
    app: chartmuseum
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: chartmuseum-deployment
  namespace: default
spec:
  replicas: 1
  minReadySeconds: 15
  strategy:
    type: RollingUpdate
    rollingUpdate:
      maxSurge: 1
      maxUnavailable: 1
  selector:
    matchLabels:
      app: chartmuseum
  template:
    metadata:
      labels:
        app: chartmuseum
    spec:
#      imagePullSecrets:
#      - name: registry-secret
      dnsPolicy: Default
      containers:
      - name: chartmuseum
        image: bitnami/chartmuseum:latest
        imagePullPolicy: IfNotPresent
        env:
          - name: TZ
            value: Asia/Shanghai
        ports:
        - containerPort: 8080
        resources: {}
---
apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
  labels:
  name: chartmuseum
  namespace: default
spec:
  entryPoints:
    - web
  routes:
  - match: Host(`chartmuseum.local`) && PathPrefix(`/{path:[a-zA-Z*]*}`)
    kind: Rule
    services:
    - name: chartmuseum
      kind: Service
      port: 80

```

## 使用chartmuseum
- 添加chartmuseum到helm

```
helm repo add localrepo http://chartmuseum.local

[root@localhost ~]# helm repo list
NAME            URL                                  
grafana         https://grafana.github.io/helm-charts
bitnami         https://charts.bitnami.com/bitnami   
localrepo       http://chartmuseum.local
```

- 安装helm push插件，推送chart

```
helm plugin install https://github.com/chartmuseum/helm-push.git
# 启用实验性功能
export HELM_EXPERIMENTAL_OCI=1

# 先在外部仓库pull一个镜像下来
helm pull bitnami/wordpress

# 推送到本地仓库
[root@centos-001 ~]# helm cm-push wordpress-12.2.8.tgz localrepo
Pushing wordpress-12.2.8.tgz to localrepo...
Done.
[root@centos-001 ~]# helm repo update localrepo
[root@centos-001 ~]# helm search repo localrepo

- 使用本地仓库安装

NOTES:
CHART NAME: wordpress
CHART VERSION: 12.2.8

** Please be patient while the chart is being deployed **

Your WordPress site can be accessed through the following DNS name from within your cluster:

wordpredd-wordpress.default.svc.cluster.local (port 80)

To access your WordPress site from outside the cluster follow the steps below:

1. Get the WordPress URL by running these commands:

NOTE: It may take a few minutes for the LoadBalancer IP to be available.
        Watch the status with: 'kubectl get svc --namespace default -w wordpredd-wordpress'

export SERVICE_IP=$(kubectl get svc --namespace default wordpredd-wordpress --template "{{ range (index .status.loadBalancer.ingress 0) }}{{.}}{{ end }}")
   echo "WordPress URL: http://$SERVICE_IP/"
   echo "WordPress Admin URL: http://$SERVICE_IP/admin"

2. Open a browser and access WordPress using the obtained URL.

3. Login with the following credentials below to see your blog:

echo Username: user
  echo Password: $(kubectl get secret --namespace default wordpredd-wordpress -o jsonpath="{.data.wordpress-password}" | base64 --decode)

# 按提示查看一下wodpress的密码，能够查询到就是创建成功了
[root@centos-001 ~]# echo Password: $(kubectl get secret --namespace default wordpredd-wordpress -o jsonpath="{.data.wordpress-password}" | base64 --decode)
Password: bD59myOIRZ
