## What is sealos

**sealos is a cloud operating system distribution with Kubernetes as its kernel.**

In the early stages, operatings systems have adopted a layered architecture, which later evolved into kernel architecture like Linux and Windows. With the emergence of container technologies, cloud OS will migrate to a "cloud kernel" architecture with strong cohesion in the future.

- 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.

## Quickstart

> Installing an HA kubernetes cluster with calico as CNI

Here `kubernetes:v1.24.0` and `calico:v3.22.1` 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/v4.0.0/sealos_4.0.0_linux_amd64.tar.gz \
   && tar zxvf sealos_4.0.0_linux_amd64.tar.gz sealos && chmod +x sealos && mv sealos /usr/bin
# Create a cluster
$ sealos run labring/kubernetes:v1.24.0 labring/calico:v3.22.1 \
     --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]
```

> Building a custom cluster image

See [Building an Example CloudImage](https://www.sealos.io/docs/examples/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.
