Feb 24, 2018

You’ve probably been using helm for a while and thinking of using it as a means to deploy your custom applications but didn’t know how exactly to go by it? Well today we’ll be going through a series of steps required to setting up your chart repository and using your custom charts via helm.

要点：

• using helm as a means to deploy your custom applications
• setting up your chart repository and using your custom charts via helm.
• what is needed in order to use custom charts with helm:
  • Custom charts
  • A chart repository
  • Working kubernetes cluster
  • Helm
• created your custom chart for your deployment(e.g. a custom mysql chart)
• upload that custom chart to a chart repository from where helm can fetch it and install it.
• using ChartMuseum as our chart repository. 也可以使用 harbor 作为 chart repo
• 以下为使用步骤（详见原文）
  • Setting up ChartMuseum
  • Configuring ChartMuseum with Helm
  • Uploading your custom chart to ChartMuseum
  • Installing your Custom Chart

Harbor version 1.6.0 is live

Sep 13, 2018

v1.6.0 with several new features

• Helm charts management
• improved LDAP support
• image replication
• database migrations

Helm charts management

Helm has become the de facto package manager of Kubernetes, making it easy to to deploy a vast array of applications. We see a dedicated Helm chart repository as a must-have system to help build new enterprise IT infrastructure and platforms. Helm charts should work seamlessly together with container images, and therefore supporting both image management and Helm chart management has become the natural direction for Harbor.

Main features

Starting with version 1.6.0, Harbor can serve as a unified cloud native registry for both image management requests and helm chart management requests. The main features are grouped into two perspectives:

Overall:

• Charts are isolated by project namespace
• Access control is applied to charts by RBAC

User management portal:

• List all the charts under the specified project namespace with list or card view
• List all the chart versions of one specified chart with list or card view
• Show the details of the specified chart version
• README content and other metadata information
• The signature prov file status
• Usage commands reference
• The dependencies of the chart version
• The value file content with the key-value view and yaml view
• Upload chart w/ prov file
• Download the specified chart version
• Delete the specified chart version

It’s easy to get started with Helm charts and Harbor using the Helm CLI:

• Use helm repo add to add Harbor as a unified chart repository with specified username, all the project namespaces accessible by that user should be visible to Helm.
• Use helm repo add to add a Harbor project as a separate chart repository, only the charts under that project are visible to Helm.
• Use the push plugin of the helm CLI to push charts to Harbor
• Use helm install to download the chart from Harbor and install it to the target Kubernetes environment
• Other commands like helm search or helm verify are also supported For more details on managing Helm charts with Harbor, see the user guide.

---

Release 1.6.0

Benefits to users

Cover both image management and helm chart management with one unified powerful cloud-native registry. Avoid spending efforts to introduce a new system in and reduce the system maintenance cost in future. In addition, image and helm chart managements follow the similar user experiences, that will definitely reduce the new system learning efforts. What's more, managing helm charts and images in one system leave enough space and flexibilities for collaborations/integration in the future.

Manage Helm Charts

Helm is a package manager for Kubernetes. Helm uses a packaging format called charts. Since version 1.6.0 Harbor is now a composite cloud-native registry which supports both container image management and Helm charts management. Access to Helm charts in Harbor is controlled by role-based access controls (RBAC) and is restricted by projects.

Manage Helm Charts via portal

• List charts
• Upload new chart
• List chart versions
• Adding labels to/remove labels from chart versions
• Filtering chart versions by labels
• View chart version details
  • Summary
  • Dependencies
  • Values

Working with Helm CLI

As a helm chart repository, Harbor can work smoothly with Helm CLI. About how to install Helm CLI, please refer install helm. Run command helm version to make sure the version of Helm CLI is v2.9.1+.

• Add harbor to the repository list
• Push charts to the repository server by CLI
• Install charts
