Module: Kubernetes

Deploy Kubernetes, the Production-Grade Container Orchestration Platform.

    Kubernetes is a production-grade, open-source container orchestration platform. It helps you automate, deploy, scale, and manage containerized applications.

    Pigsty has native support for ETCD clusters, which can be used by Kubernetes. Therefore, the pro version also provides the KUBE module for deploying production-grade Kubernetes clusters.

    The KUBE module is currently in Beta status and only available for Pro edition customers.

    However, you can directly specify node repositories in Pigsty, install Kubernetes packages, and use Pigsty to adjust environment configurations and provision nodes for K8S deployment, solving the last mile delivery problem.

    SealOS

    SealOS is a lightweight, high-performance, and easy-to-use Kubernetes distribution. It is designed to simplify the deployment and management of Kubernetes clusters.

    Pigsty provides SealOS 5.0 RPM and DEB packages in the Infra repository, which can be downloaded and installed directly, and use SealOS to manage clusters.

    ./node.yml -t node_install -e '{"node_repo_modules":"infra","node_packages":["sealos"]}'

    Kubernetes

    If you prefer to deploy Kubernetes using the classic Kubeadm, please refer to the module reference below.

    ./node.yml -t node_install -e '{"node_repo_modules":"kube","node_packages":["kubeadm,kubelet,kubectl"]}'

    Kubernetes supports multiple container runtimes. If you want to use Containerd as the container runtime, please make sure Containerd is installed on the node.

    ./node.yml -t node_install -e '{"node_repo_modules":"node,docker","node_packages":["containerd.io"]}'

    If you want to use Docker as the container runtime, you need to install Docker and bridge with the cri-dockerd project (not available on EL9/D11/U20 yet):

    ./node.yml -t node_install -e '{"node_repo_modules":"node,infra,docker","node_packages":["docker-ce,docker-compose-plugin,cri-dockerd"]}'
