base on Install Kubernetes/K3s, and related cloud-native add-ons, it supports all-in-one, multi-node, and HA 🔥 ⎈ 🐳 <div align=center><img src="docs/images/kubekey-logo.svg?raw=true"></div> [](https://github.com/kubesphere/kubekey/actions/workflows/golangci-lint.yaml?query=event%3Apush+branch%3Amain+workflow%3ACI) > English | [中文](README_zh-CN.md) **👋 Welcome to KubeKey!** KubeKey is an open-source lightweight task flow execution tool. It provides a flexible and fast way to install Kubernetes. > KubeKey has passed the [CNCF Kubernetes Conformance Certification](https://www.cncf.io/certification/software-conformance/) # Comparison of new features in 3.x 1. Expanded from Kubernetes lifecycle management tool to task execution tool (flow design refers to [Ansible](https://github.com/ansible/ansible)) 2. Supports multiple ways to manage task templates: git, local, etc. 3. Supports multiple node connection methods, including: local, ssh, kubernetes, prometheus. 4. Supports cloud-native automated batch task management 5. Advanced features: UI page (not yet open) # Install kubekey ## Install in Kubernetes Install kubekey via helm. ```shell helm upgrade --install --create-namespace -n kubekey-system kubekey config/kubekey ``` ## Binary Get the corresponding binary files from the [release](https://github.com/kubesphere/kubekey/releases) page. ## Download Binary with UI **UI only support after v4.0.0** ```shell VERSION=v4.0.0 WEB_INSTALLER_VERSION=v1.0.0 hack/downloadKubekey.sh # run with UI kk web --schema-path schema --ui-path dist ``` > If there is a config.yaml file in the current directory, running `./package.sh config.yaml` to build an offline package. # Deploy Kubernetes - Supported deployment environments: Linux distributions - almaLinux: 9.0 (not fully tested) - centOS: 8 - debian: 10, 11 - kylin: V10SP3 (not fully tested) - ubuntu: 18.04, 20.04, 22.04, 24.04. - Supported Kubernetes versions: v1.23.x ~ v1.33.x ## Requirements - One or more computers running Linux operating systems compatible with deb/rpm; for example: Ubuntu or CentOS. - Each machine should have more than 2 GB of memory; applications will be limited if memory is insufficient. - Control plane nodes should have at least 2 CPUs. - Full network connectivity among all machines in the cluster. You can use public or private networks. ## Define node information kubekey uses the `inventory` resource to define node connection information. You can use `kk create inventory` to get the default inventory.yaml resource. The default `inventory.yaml` configuration is as follows: ```yaml apiVersion: kubekey.kubesphere.io/v1 kind: Inventory metadata: name: default spec: hosts: # your can set all nodes here. or set nodes on special groups. # node1: # connector: # type: ssh # host: node1 # port: 22 # user: root # password: 123456 groups: # all kubernetes nodes. k8s_cluster: groups: - kube_control_plane - kube_worker # control_plane nodes kube_control_plane: hosts: - localhost # worker nodes kube_worker: hosts: - localhost # etcd nodes when etcd_deployment_type is external etcd: hosts: - localhost # image_registry: # hosts: # - localhost # nfs nodes for registry storage. and kubernetes nfs storage # nfs: # hosts: # - localhost ``` The inventory contains the following built-in groups: 1. k8s_cluster: Kubernetes cluster. Contains two subgroups: kube_control_plane, kube_worker 2. kube_control_plane: control_plane node group in the Kubernetes cluster 3. kube_worker: worker node group in the Kubernetes cluster. 4. etcd: node group for installing etcd cluster. 5. image_registry: node group for installing image registry (including harbor, registry) 6. nfs: node group for installing nfs. ## Define key configuration information kubekey uses the `config` resource to define node connection information. You can use `kk create config --with-kubernetes v1.33.1` to get the default inventory.yaml resource. The default `config.yaml` configuration is as follows: Default config configurations are provided as references for different Kubernetes versions: - [Config for installing Kubernetes v1.23.x](builtin/core/defaults/config/v1.23.yaml) - [Config for installing Kubernetes v1.24.x](builtin/core/defaults/config/v1.24.yaml) - [Config for installing Kubernetes v1.25.x](builtin/core/defaults/config/v1.25.yaml) - [Config for installing Kubernetes v1.26.x](builtin/core/defaults/config/v1.26.yaml) - [Config for installing Kubernetes v1.27.x](builtin/core/defaults/config/v1.27.yaml) - [Config for installing Kubernetes v1.28.x](builtin/core/defaults/config/v1.28.yaml) - [Config for installing Kubernetes v1.29.x](builtin/core/defaults/config/v1.29.yaml) - [Config for installing Kubernetes v1.30.x](builtin/core/defaults/config/v1.30.yaml) - [Config for installing Kubernetes v1.31.x](builtin/core/defaults/config/v1.31.yaml) - [Config for installing Kubernetes v1.32.x](builtin/core/defaults/config/v1.32.yaml) - [Config for installing Kubernetes v1.33.x](builtin/core/defaults/config/v1.33.yaml) ## Install cluster ```shell kk create cluster -i inventory.yaml -c config.yaml ``` If `-i inventory.yaml` is not provided, the default inventory.yaml is used. Kubernetes will only be installed on the executing machine. If `-c config.yaml` is not provided, the default config.yaml is used. Installs Kubernetes version v1.33.1. # Documentation **[Project template writing specification](docs/en/001-project.md)** **[Template syntax](docs/en/101-syntax.md)** **[Parameter definition](docs/en/201-variable.md)** **[Cluster management](docs/en/core/README.md)** ", Assign "at most 3 tags" to the expected json: {"id":"8544","tags":[]} "only from the tags list I provide: [{"id":77,"name":"3d"},{"id":89,"name":"agent"},{"id":17,"name":"ai"},{"id":54,"name":"algorithm"},{"id":24,"name":"api"},{"id":44,"name":"authentication"},{"id":3,"name":"aws"},{"id":27,"name":"backend"},{"id":60,"name":"benchmark"},{"id":72,"name":"best-practices"},{"id":39,"name":"bitcoin"},{"id":37,"name":"blockchain"},{"id":1,"name":"blog"},{"id":45,"name":"bundler"},{"id":58,"name":"cache"},{"id":21,"name":"chat"},{"id":49,"name":"cicd"},{"id":4,"name":"cli"},{"id":64,"name":"cloud-native"},{"id":48,"name":"cms"},{"id":61,"name":"compiler"},{"id":68,"name":"containerization"},{"id":92,"name":"crm"},{"id":34,"name":"data"},{"id":47,"name":"database"},{"id":8,"name":"declarative-gui "},{"id":9,"name":"deploy-tool"},{"id":53,"name":"desktop-app"},{"id":6,"name":"dev-exp-lib"},{"id":59,"name":"dev-tool"},{"id":13,"name":"ecommerce"},{"id":26,"name":"editor"},{"id":66,"name":"emulator"},{"id":62,"name":"filesystem"},{"id":80,"name":"finance"},{"id":15,"name":"firmware"},{"id":73,"name":"for-fun"},{"id":2,"name":"framework"},{"id":11,"name":"frontend"},{"id":22,"name":"game"},{"id":81,"name":"game-engine "},{"id":23,"name":"graphql"},{"id":84,"name":"gui"},{"id":91,"name":"http"},{"id":5,"name":"http-client"},{"id":51,"name":"iac"},{"id":30,"name":"ide"},{"id":78,"name":"iot"},{"id":40,"name":"json"},{"id":83,"name":"julian"},{"id":38,"name":"k8s"},{"id":31,"name":"language"},{"id":10,"name":"learning-resource"},{"id":33,"name":"lib"},{"id":41,"name":"linter"},{"id":28,"name":"lms"},{"id":16,"name":"logging"},{"id":76,"name":"low-code"},{"id":90,"name":"message-queue"},{"id":42,"name":"mobile-app"},{"id":18,"name":"monitoring"},{"id":36,"name":"networking"},{"id":7,"name":"node-version"},{"id":55,"name":"nosql"},{"id":57,"name":"observability"},{"id":46,"name":"orm"},{"id":52,"name":"os"},{"id":14,"name":"parser"},{"id":74,"name":"react"},{"id":82,"name":"real-time"},{"id":56,"name":"robot"},{"id":65,"name":"runtime"},{"id":32,"name":"sdk"},{"id":71,"name":"search"},{"id":63,"name":"secrets"},{"id":25,"name":"security"},{"id":85,"name":"server"},{"id":86,"name":"serverless"},{"id":70,"name":"storage"},{"id":75,"name":"system-design"},{"id":79,"name":"terminal"},{"id":29,"name":"testing"},{"id":12,"name":"ui"},{"id":50,"name":"ux"},{"id":88,"name":"video"},{"id":20,"name":"web-app"},{"id":35,"name":"web-server"},{"id":43,"name":"webassembly"},{"id":69,"name":"workflow"},{"id":87,"name":"yaml"}]" returns me the "expected json"
