## Run a Kubernetes cluster

## What is sealos

**sealos is a Kubernetes distribution, a general-purpose cloud operating system for managing cloud-native applications.**

![](https://user-images.githubusercontent.com/8912557/173866494-379ba0dd-05af-4095-b63d-08f594581c52.png)

- From now on, think of all your machines as an abstract supercomputer whose operating system is sealos, where Kubernetes serves as the OS kernel.
- Instead of IaaS, PaaS and SaaS, there will only be cloud OS drivers(CSI, CNI and CRI implementations), cloud OS kernel(Kubernetes) and distributed applications.

Use the cloud like a PC desktop, Freely run and uninstall any distributed applications:

## Quickstart

> Installing an HA Kubernetes cluster with calico as CNI

Here `kubernetes:v1.24.0` and `calico:v3.24.1` are the cluster images in the registry which are fully compatible with OCI standard. Wonder if we can use flannel instead? Of course!

```shell script
# Download and install sealos. sealos is a golang binary so you can just download and copy to bin. You may also download it from release page.
$ wget  https://github.com/labring/sealos/releases/download/v4.1.3/sealos_4.1.3_linux_amd64.tar.gz  && \
    tar -zxvf sealos_4.1.3_linux_amd64.tar.gz sealos &&  chmod +x sealos && mv sealos /usr/bin 
# Create a cluster
$ sealos run labring/kubernetes:v1.25.0 labring/helm:v3.8.2 labring/calico:v3.24.1 \
     --masters 192.168.64.2,192.168.64.22,192.168.64.20 \
     --nodes 192.168.64.21,192.168.64.19 -p [your-ssh-passwd]
```

* Supported Kubernetes versions: [240+ Kubernetes versions](https://hub.docker.com/r/labring/kubernetes/tags) [Kubernetes use cri-docker runtime](https://hub.docker.com/r/labring/kubernetes-docker/tags)
* Other distributed [applications images](https://hub.docker.com/u/labring)

> Single host

```shell
$ sealos run labring/kubernetes:v1.25.0 labring/helm:v3.8.2 labring/calico:v3.24.1 --single
# remove taint
$ kubectl taint nodes --all node-role.kubernetes.io/master:NoSchedule-
```

> Building a custom cluster image

See [Building an Example CloudImage](https://www.sealos.io/docs/getting-started/build-example-cloudimage).

> Storage, message queue, database, etc.

Don't be shocked by the following:

```shell script
sealos run labring/helm:v3.8.2 # install helm
sealos run labring/openebs:v1.9.0 # install openebs
sealos run labring/minio-operator:v4.4.16 labring/ingress-nginx:4.1.0 \
   labring/mysql-operator:8.0.23-14.1 labring/redis-operator:3.1.4 # oneliner
```

And now everything is ready.

## Use cri-docker image

```shell
sealos run labring/kubernetes-docker:v1.20.5-4.1.3 labring/calico:v3.24.1 \
     --masters 192.168.64.2,192.168.64.22,192.168.64.20 \
     --nodes 192.168.64.21,192.168.64.19 -p [your-ssh-passwd]
```
