Prerequisites

• Kubernetes with extensions/v1beta1 available
• [If enabled] A persistent storage resource and RW access to it
• [If enabled] Kubernetes StorageClass for dynamic provisioning

Configuration

By default this chart will not have persistent storage, and the API service will be DISABLED. This protects against unauthorized access to the API with default configuration values.

For a more robust solution supply helm install with a custom values.yaml
You are also required to create the StorageClass resource ahead of time:

kubectl create -f /path/to/storage_class.yaml

Installation

helm install --name my-chartmuseum -f custom.yaml incubator/chartmuseum

Using with Amazon S3

Make sure your environment is properly setup to access my-s3-bucket

You need at least the following permissions inside your IAM Policy

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "AllowListObjects",
      "Effect": "Allow",
      "Action": [
        "s3:ListBucket"
      ],
      "Resource": "arn:aws:s3:::my-s3-bucket"
    },
    {
      "Sid": "AllowObjectsCRUD",
      "Effect": "Allow",
      "Action": [
        "s3:DeleteObject",
        "s3:GetObject",
        "s3:PutObject"
      ],
      "Resource": "arn:aws:s3:::my-s3-bucket/*"
    }
  ]
}

You can grant it to chartmuseum by several ways:

permissions grant with access keys

Grant permissions to special user and us it's access keys for auth on aws

Specify custom.yaml with such values

env:
  open:
    STORAGE: amazon
    STORAGE_AMAZON_BUCKET: my-s3-bucket
    STORAGE_AMAZON_PREFIX:
    STORAGE_AMAZON_REGION: us-east-1
  secret:
    AWS_ACCESS_KEY_ID: "********" ## aws access key id value
    AWS_SECRET_ACCESS_KEY: "********" ## aws access key secret value 

Run command to install

helm install --name my-chartmuseum -f custom.yaml incubator/chartmuseum

permissions grant with IAM instance profile

You can grant permissions to k8s node IAM instance profile. For more information read this article

Specify custom.yaml with such values

env:
  open:
    STORAGE: amazon
    STORAGE_AMAZON_BUCKET: my-s3-bucket
    STORAGE_AMAZON_PREFIX:
    STORAGE_AMAZON_REGION: us-east-1

Run command to install

helm install --name my-chartmuseum -f custom.yaml incubator/chartmuseum

permissions grant with IAM assumed role

To provide access with assumed role you need to install kube2iam and create role with granded permissions.

Specify custom.yaml with such values

env:
  open:
    STORAGE: amazon
    STORAGE_AMAZON_BUCKET: my-s3-bucket
    STORAGE_AMAZON_PREFIX:
    STORAGE_AMAZON_REGION: us-east-1
replica:
  annotations:
    iam.amazonaws.com/role: "{assumed role name}"

Run command to install

helm install --name my-chartmuseum -f custom.yaml incubator/chartmuseum

Using with Google Cloud Storage

Make sure your environment is properly setup to access my-gcs-bucket

Specify custom.yaml with such values

env:
  open:
    STORAGE: google
    STORAGE_GOOGLE_BUCKET: my-gcs-bucket
    STORAGE_GOOGLE_PREFIX:    

Run command to install

helm install --name my-chartmuseum -f custom.yaml incubator/chartmuseum

Using with Microsoft Azure Blob Storage

Make sure your environment is properly setup to access mycontainer.

To do so, you must set the following env vars:

• AZURE_STORAGE_ACCOUNT
• AZURE_STORAGE_ACCESS_KEY

Specify custom.yaml with such values

env:
  open:
    STORAGE: microsoft
    STORAGE_MICROSOFT_CONTAINER: mycontainer
    # prefix to store charts for microsoft storage backend
    STORAGE_MICROSOFT_PREFIX:    
  secret:
    AZURE_STORAGE_ACCOUNT: "********" ## azure storage account
    AZURE_STORAGE_ACCESS_KEY: "********" ## azure storage account access key 

Run command to install

helm install --name my-chartmuseum -f custom.yaml incubator/chartmuseum

Using with Alibaba Cloud OSS Storage

Make sure your environment is properly setup to access my-oss-bucket.

To do so, you must set the following env vars:

• ALIBABA_CLOUD_ACCESS_KEY_ID
• ALIBABA_CLOUD_ACCESS_KEY_SECRET

Specify custom.yaml with such values

env:
  open:
    STORAGE: alibaba
    STORAGE_ALIBABA_BUCKET: my-oss-bucket
    STORAGE_ALIBABA_PREFIX:
    STORAGE_ALIBABA_ENDPOINT: oss-cn-beijing.aliyuncs.com
  secret:
    ALIBABA_CLOUD_ACCESS_KEY_ID: "********" ## alibaba OSS access key id
    ALIBABA_CLOUD_ACCESS_KEY_SECRET: "********" ## alibaba OSS access key secret 

Run command to install

helm install --name my-chartmuseum -f custom.yaml incubator/chartmuseum

Using with local filesystem storage

By default chartmuseum use local filesystem storage. But on pod recreation if will lose all charts, to prevent that enable persistent storage.

env:
  open:
    STORAGE: local
persistence:
  enabled: true
  accessMode: ReadWriteOnce
  size: 8Gi
  ## A manually managed Persistent Volume and Claim
  ## Requires Persistence.enabled: true
  ## If defined, PVC must be created manually before volume will be bound
  # existingClaim:

  ## Chartmuseum data Persistent Volume Storage Class
  ## If defined, storageClassName: <storageClass>
  ## If set to "-", storageClassName: "", which disables dynamic provisioning
  ## If undefined (the default) or set to null, no storageClassName spec is
  ##   set, choosing the default provisioner.  (gp2 on AWS, standard on
  ##   GKE, AWS & OpenStack)
  ##
  # storageClass: "-"

Run command to install

helm install --name my-chartmuseum -f custom.yaml incubator/chartmuseum

Example storage class

Example storage-class.yaml provided here for use with a Ceph cluster.

kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
  name: storage-volume
provisioner: kubernetes.io/rbd
parameters:
  monitors: "10.11.12.13:4567,10.11.12.14:4567"
  adminId: admin
  adminSecretName: thesecret
  adminSecretNamespace: default
  pool: chartstore
  userId: user
  userSecretName: thesecret 

Uninstall

By default, a deliberate uninstall will result in the persistent volume claim being deleted.

helm delete my-chartmuseum

To delete the deployment and its history:

helm delete --purge my-chartmuseum
