Manage kubernetes in the most light and convenient way

English | 中文

KubeClipper is a lightweight web service that provides a friendly web console GUI, APIs, and a CLI tool for Kubernetes cluster lifecycle management.
KubeClipper provides flexible Kubernetes as a Service (KaaS), which allows users to rapidly deploy K8S clusters anywhere(cloud, hypervisor, bare metal) and provides continuous lifecycle management capabilities (installation, deleting, upgrading, backup and restoration, cluster scaling, remote access, plug-in management, application store).see Feature List for details.

🎯 Project Goal：Manage Kubernetes in the most light and convenient way.

• 🚀 Cluster Installation Optimization
  • Use images to encapsulate installation package resources to reduce complexity. Reuse mature image technology
• 💻 Kubernetes Web Console
  • Workload resources & monitoring presentation
  • Tenant based cluster access control
• 📦 Application Store
  • Application lifecycle management
  • Support web UI & CLI interface
• 🧩 Common Application and Plugin Integrations
  • LB & Ingress
  • Monitoring
  • Kubernetes Dashboard
  • KubeEdge
• 🕸 Managed Clusters
  • Support KoK clusters.

Explore the architecture of Kubeclipper on kubeclipper.io.

For users who are new to KubeClipper and want to get started quickly, it is recommended to use the All-in-One installation mode, which can help you quickly deploy KubeClipper with zero configuration.

KubeClipper itself does not take up too many resources, but in order to run Kubernetes better in the future, it is recommended that the hardware configuration should not be lower than the minimum requirements.

You only need to prepare a host with reference to the following requirements for machine hardware and operating system.

• Make sure your machine meets the minimum hardware requirements: CPU >= 2 cores, RAM >= 2GB.
• Operating System: CentOS 7.x / Ubuntu 18.04 / Ubuntu 20.04.

• Nodes must be able to connect via SSH.

• You can use the sudo / curl / wget / tar command on this node.

It is recommended that your operating system is in a clean state (no additional software is installed), otherwise, conflicts may occur.

KubeClipper provides command line tools 🔧 kcctl to simplify operations.

You can download the latest version of kcctl directly with the following command:

# Install latest release
curl -sfL https://oss.kubeclipper.io/get-kubeclipper.sh | bash -
# In China, you can add env "KC_REGION=cn", we use registry.aliyuncs.com/google_containers instead of k8s.gcr.io
curl -sfL https://oss.kubeclipper.io/get-kubeclipper.sh | KC_REGION=cn bash -
# The latest release version is downloaded by default. You can download the specified version. For example, specify the master development version to be installed
curl -sfL https://oss.kubeclipper.io/get-kubeclipper.sh | KC_REGION=cn KC_VERSION=master bash -

It is highly recommended that you install the latest release to experience more features.
You can also download the specified version on the GitHub Release Page.

Check if the installation is successful with the following command:

kcctl version

In this quick start tutorial, you only need to run just one command for installation:

If you want to install AIO mode

# install default release
kcctl deploy
# you can use KC_VERSION to install the specified version, default is latest release
KC_VERSION=master kcctl deploy

If you want to install multi node, Use kcctl deploy -h for more information about a command

After you runn this command, kcctl will check your installation environment and enter the installation process, if the conditions are met.

After printing the KubeClipper banner, the installation is complete.

When deployed successfully, you can open a browser and visit http://$IP to enter the KubeClipper console.

You can log in with the default account and password admin / Thinkbig1 .

You may need to configure port forwarding rules and open ports in security groups for external users to access the console.

When kubeclipper is deployed successfully, you can use the kcctl tool or console to create a k8s cluster. In the quick start tutorial, we use the kcctl tool to create.

Then create a k8s cluster with the following command:

NODE=$(kcctl get node -o yaml|grep ipv4DefaultIP:|sed 's/ipv4DefaultIP: //')

kcctl create cluster --master $NODE --name demo --untaint-master

The cluster creation will be completed in about 3 minutes, or you can use the following command to view the cluster status:

kcctl get cluster -o yaml|grep status -A5

You can also enter the console to view real-time logs.

Once the cluster enter the Running state , it means that the creation is complete. You can use kubectl get cs command to view the cluster status.

1. fork repo and clone
2. run etcd locally, usually use docker / podman to run etcd container

   export HostIP="Your-IP"
   docker run -d \
   --net host \
   k8s.gcr.io/etcd:3.5.0-0 etcd \
   --advertise-client-urls http://${HostIP}:2379 \
   --initial-advertise-peer-urls http://${HostIP}:2380 \
   --initial-cluster=infra0=http://${HostIP}:2380 \
   --listen-client-urls http://${HostIP}:2379,http://127.0.0.1:2379 \
   --listen-metrics-urls http://127.0.0.1:2381 \
   --listen-peer-urls http://${HostIP}:2380 \
   --name infra0 \
   --snapshot-count=10000 \
   --data-dir=/var/lib/etcd

3. change kubeclipper-server.yaml etcd.serverList to your locally etcd cluster
4. make build
5. ./dist/kubeclipper-server serve
