Quickstart

Installing a highly available Kubernetes cluster with Calico as the container network interface (CNI).

Here, the Cluster images kubernetes:v1.24.0-4.2.0 and calico:v3.24.1 stored in the registry are fully compliant with the OCI standard. However, if you prefer to use flannel, it is also an option.

# Download and install Sealos, which is a binary tool written in Golang. Simply download it and copy it to the bin directory. You can also download it from the release page.
$ wget  https://github.com/labring/sealos/releases/download/v4.2.0/sealos_4.2.0_linux_amd64.tar.gz  && \
    tar -zxvf sealos_4.2.0_linux_amd64.tar.gz sealos &&  chmod +x sealos && mv sealos /usr/bin 
# Create a cluster
$ sealos run labring/kubernetes:v1.25.0-4.2.0 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 Kubernetes with cri-docker runtime
Other images for distributed applications

Single host

$ sealos run labring/kubernetes:v1.25.0-4.2.0 labring/helm:v3.8.2 labring/calico:v3.24.1

Building a custom Cluster image

Reference Building an Example CloudImage.

Storage, Message queue, Database, etc.

Don't be shocked by the following:

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 Kubernetes Cluster image with cri-docker runtime

sealos run labring/kubernetes-docker:v1.20.8-4.2.0 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]
