kubekey's Introduction

English | 中文 | 日本語

👋 Welcome to KubeKey!

KubeKey is an open-source lightweight tool for deploying Kubernetes clusters. It provides a flexible, rapid, and convenient way to install Kubernetes/K3s only, both Kubernetes/K3s and KubeSphere, and related cloud-native add-ons. It is also an efficient tool to scale and upgrade your cluster.

In addition, KubeKey also supports customized Air-Gap package, which is convenient for users to quickly deploy clusters in offline environments.

KubeKey has passed CNCF kubernetes conformance verification.

Use KubeKey in the following three scenarios.

Install Kubernetes/K3s only
Install Kubernetes/K3s and KubeSphere together in one command
Install Kubernetes/K3s first, then deploy KubeSphere on it using ks-installer

Important: If you have existing Kubernetes clusters, please refer to ks-installer (Install KubeSphere on existing Kubernetes cluster).

Container Manager

Docker / containerd / CRI-O / iSula

Kata Containers can be set to automatically install and configure runtime class for it when the container manager is containerd or CRI-O.

Network Plugins

Calico / Flannel / Cilium / Kube-OVN / Multus-CNI

Kubekey also supports users to set the network plugin to none if there is a requirement for custom network plugin.

Requirements and Recommendations

Minimum resource requirements (For Minimal Installation of KubeSphere only)：
- 2 vCPUs
- 4 GB RAM
- 20 GB Storage

/var/lib/docker is mainly used to store the container data, and will gradually increase in size during use and operation. In the case of a production environment, it is recommended that /var/lib/docker mounts a drive separately.

OS requirements:
- SSH can access to all nodes.
- Time synchronization for all nodes.
- sudo/curl/openssl should be used in all nodes.
- docker can be installed by yourself or by KubeKey.
- Red Hat includes SELinux in its Linux release. It is recommended to close SELinux or switch the mode of SELinux to Permissive

It's recommended that Your OS is clean (without any other software installed), otherwise there may be conflicts.

A container image mirror (accelerator) is recommended to be prepared if you have trouble downloading images from dockerhub.io. Configure registry-mirrors for the Docker daemon.

KubeKey will install OpenEBS to provision LocalPV for development and testing environment by default, this is convenient for new users. For production, please use NFS / Ceph / GlusterFS or commercial products as persistent storage, and install the relevant client in all nodes.

If you encounter Permission denied when copying, it is recommended to check SELinux and turn off it first

Dependency requirements:

KubeKey can install Kubernetes and KubeSphere together. Some dependencies need to be installed before installing kubernetes after version 1.18. You can refer to the list below to check and install the relevant dependencies on your node in advance.

	Kubernetes Version ≥ 1.18
`socat`	Required
`conntrack`	Required
`ebtables`	Optional but recommended
`ipset`	Optional but recommended
`ipvsadm`	Optional but recommended

Networking and DNS requirements:
- Make sure the DNS address in /etc/resolv.conf is available. Otherwise, it may cause some issues of DNS in cluster.
- If your network configuration uses Firewall or Security Group，you must ensure infrastructure components can communicate with each other through specific ports. It's recommended that you turn off the firewall or follow the link configuriation: NetworkAccess.

Usage

Get the KubeKey Executable File

The fastest way to get KubeKey is to use the script:
```
curl -sfL https://get-kk.kubesphere.io | sh -
```
Binary downloads of the KubeKey also can be found on the Releases page. Unpack the binary and you are good to go!

Build Binary from Source Code

git clone https://github.com/kubesphere/kubekey.git
cd kubekey
make kk

Create a Cluster

Quick Start

Quick Start is for all-in-one installation which is a good start to get familiar with Kubernetes and KubeSphere.

Note: Since Kubernetes temporarily does not support uppercase NodeName, contains uppercase letters in the hostname will lead to subsequent installation error

Command

If you have problem to access https://storage.googleapis.com, execute first export KKZONE=cn.

./kk create cluster [--with-kubernetes version] [--with-kubesphere version]

Examples

Create a pure Kubernetes cluster with default version (Kubernetes v1.23.10).
```
./kk create cluster
```

Create a Kubernetes cluster with a specified version.

./kk create cluster --with-kubernetes v1.24.1 --container-manager containerd

Create a Kubernetes cluster with KubeSphere installed.
```
./kk create cluster --with-kubesphere v3.2.1
```

Advanced

You have more control to customize parameters or create a multi-node cluster using the advanced installation. Specifically, create a cluster by specifying a configuration file.

If you have problem to access https://storage.googleapis.com, execute first export KKZONE=cn.

First, create an example configuration file
```
./kk create config [--with-kubernetes version] [--with-kubesphere version] [(-f | --filename) path]
```
examples:
- create an example config file with default configurations. You also can specify the file that could be a different filename, or in different folder.
```
./kk create config [-f ~/myfolder/abc.yaml]
```
- with KubeSphere
```
./kk create config --with-kubesphere v3.2.1
```
Modify the file config-sample.yaml according to your environment

Note: Since Kubernetes temporarily does not support uppercase NodeName, contains uppercase letters in workerNode`s name will lead to subsequent installation error

A persistent storage is required in the cluster, when kubesphere will be installed. The local volume is used default. If you want to use other persistent storage, please refer to addons.

Create a cluster using the configuration file
```
./kk create cluster -f config-sample.yaml
```

Enable Multi-cluster Management

By default, KubeKey will only install a solo cluster without Kubernetes federation. If you want to set up a multi-cluster control plane to centrally manage multiple clusters using KubeSphere, you need to set the ClusterRole in config-example.yaml. For multi-cluster user guide, please refer to How to Enable the Multi-cluster Feature.

Enable Pluggable Components

KubeSphere has decoupled some core feature components since v2.1.0. These components are designed to be pluggable which means you can enable them either before or after installation. By default, KubeSphere will be started with a minimal installation if you do not enable them.

You can enable any of them according to your demands. It is highly recommended that you install these pluggable components to discover the full-stack features and capabilities provided by KubeSphere. Please ensure your machines have sufficient CPU and memory before enabling them. See Enable Pluggable Components for the details.

Add Nodes

Add new node's information to the cluster config file, then apply the changes.

./kk add nodes -f config-sample.yaml

Delete Nodes

You can delete the node by the following command，the nodeName that needs to be removed.

./kk delete node <nodeName> -f config-sample.yaml

Delete Cluster

You can delete the cluster by the following command:

If you started with the quick start (all-in-one):

./kk delete cluster

If you started with the advanced (created with a configuration file):

./kk delete cluster [-f config-sample.yaml]

Upgrade Cluster

Allinone

Upgrading cluster with a specified version.

./kk upgrade [--with-kubernetes version] [--with-kubesphere version]

Support upgrading Kubernetes only.
Support upgrading KubeSphere only.
Support upgrading Kubernetes and KubeSphere.

Multi-nodes

Upgrading cluster with a specified configuration file.

./kk upgrade [--with-kubernetes version] [--with-kubesphere version] [(-f | --filename) path]

If --with-kubernetes or --with-kubesphere is specified, the configuration file will be also updated.
Use -f to specify the configuration file which was generated for cluster creation.

Note: Upgrading multi-nodes cluster need a specified configuration file. If the cluster was installed without kubekey or the configuration file for installation was not found, the configuration file needs to be created by yourself or following command.

Getting cluster info and generating kubekey's configuration file (optional).

./kk create config [--from-cluster] [(-f | --filename) path] [--kubeconfig path]

--from-cluster means fetching cluster's information from an existing cluster.
-f refers to the path where the configuration file is generated.
--kubeconfig refers to the path where the kubeconfig.
After generating the configuration file, some parameters need to be filled in, such as the ssh information of the nodes.

allinone installed failed because of sc missing

./kk create cluster --with-kubernetes v1.18.3 install failed. The error msg shows as below. But I think allinone should have localVolume as default.

command completion support

Like kubectl, it is better to provide such completion feature to users.

Output the total length of the installation process in the log.

This is useful for users to know the duration of the installation process.

hyberKube & client of rbd&nfs&glusterfs

Could hyberKube & client of rbd&nfs&glusterfs be supported by KK in the future ?

config-sample storage doc

Need a doc about how to create storage class for the common storage providers such as ceph, glusterfs, nfs, and the ones from famous cloud providers.

improvement suggestion

I found the deployment of ks-installer takes significant time. It would be better to pul flashing dots like ....... as the previous installer does so users know they should wait instead suspect it's dead.

need a guild of offline installation

More K8s versions support

I tried 1.18.5, 1.17.8, 1.16.12. All threw the following error.

provide -y

Users may have devops requirement for automation testing. It is better to provide such command ./kk create cluster -f xxxx.yaml -y so that the command will continue installing without manually typing yes

failed to install ks+k8s v1.18.5 using binary

I build the binary from the kubekey Git repo, but it reminds the installation errors as follows:

$ ./kk create cluster -f config-sample.yaml

This is a simple check of your environment.
Before installation, you should ensure that your machines meet all requirements specified at
https://github.com/kubesphere/kubekey#requirements-and-recommendations

Continue this installation? [yes/no]: yes

need to judge if config-sample.yaml exists or not

When using ./kk create config to create a default sample file named config-sample.yaml, it's better to judge if such file already exists or not, and if so, ask user whether to overwrite it or abort.

Provide a default all-in-one config file

Hi, can you update the link for the example all-in-one config file in the READEME.
Currently, that link does not direct to a correct place:

https://github.com/kubesphere/kubekey/docs/config-example.md

Failed to deploy network plugin: interrupted by error

The caclio installed failed. Then I install calico manually as the above command, it's also the same error.

The calico.yaml as follows:

...
kind: Deployment
metadata:
  name: calico-kube-controllers
  namespace: kube-system
  labels:
    k8s-app: calico-kube-controllers

install msg refine

./kk create cluster is to create a Kubernetes cluster only, but it shows "kubesphere" has been added to your repositories. This will confuse user.

It's better to remove the blank lines in the ks config of the sample config file

install timeout

Is it network problem?

install result msg shows incorrect IP

My machine is 192.168.100.3, but here shows 192.168.100.2

Monitoring installation pops etcd client key error, then prometheus can not find etcd secert

Install KS on one node cluster using kk, with monitoring component selected.

Then prometheus failed to start

Failed to scale all-in-one to multi-node

Scaling member cluster removes the cluster configuration

I scale a member cluster from allinone to two-node cluster. The clusterRole becomes none. The host still shows the member but can't go into the cluster and keep logging the host console out.

Unfortunately, an error has occurred:
timed out waiting for the condition

This error is likely caused by:
- The kubelet is not running
- The kubelet is unhealthy due to a misconfiguration of the node in some way (required cgroups disabled)

Installer failed due to network

When network is not very good, the installation may interrupt and exit.Maybe a retry is needed.

After taking the following
