添加计算集群

KubeCube 可以添加其它集群作为计算集群，前提是，计算集群能够访问管控集群的 k8s api-server 和 KubeCube，默认情况下 KubeCube 使用 NodePort 对外暴露服务，用户可自行使用 ingress 进行暴露

方式一：部署新集群并添加

在 linux 机器上，需要构建 Kubernetes 集群并安装 KubeCube 依赖项

开始安装

  1. KUBECUBE_VERSION=v1.0.0
  1. export CUSTOMIZE="true";curl -fsSL https://kubecube.nos-eastchina1.126.net/kubecube-installer/${KUBECUBE_VERSION}/entry.sh | bash

设置安装脚本参数

该安装模式下，需要修改以下参数：

INSTALL_KUBECUBE_PIVOT=“false”

INSTALL_KUBECUBE_MEMBER=“true”

INSTALL_KUBERNETES=“true”

MEMBER_CLUSTER_NAME=“member-1”

MASTER_IP=”${node ip}”

KUBECUBE_HOST=”${pivot node ip}”

MEMBER_CLUSTER_NAME 表示计算集群的名字，注意，不能与已有的计算集群名称同名 ${node ip} 表示你运行脚本所在 node 机器的 ip，该 node 需要可操作 kubectl ${pivot node ip} 表示管控集群 node 机器的 ip，用于向 KubeCube 注册集群

  1. # if install kubecube on pivot cluster
  2. INSTALL_KUBECUBE_PIVOT="false"
  4. # if install kubecube on member cluster
  5. INSTALL_KUBECUBE_MEMBER="true"
  7. # if install k8s
  8. INSTALL_KUBERNETES="true"
  10. # there are four node mode below:
  11. # "master" : node will be installed as a master of cluster
  12. # "node-join-master" : node will be install as a worker of cluster to join master
  13. # "control-plane-master" : node will be installed as a master to control plane of cluster
  14. # "node-join-control-plane" : node will be installed as a master to join control plane
  15. NODE_MODE="master"
  17. # +optional
  18. # must be set when INSTALL_KUBECUBE_MEMBER="true"
  19. # this value is the name of member cluster you
  20. # want to take over
  21. MEMBER_CLUSTER_NAME="member-1"
  23. # +optional
  24. # must be set when NODE_MODE="control-plane-master"
  25. # or "node-join-control-plane"
  26. CONTROL_PLANE_ENDPOINT="" #{ip}:{port} , dns
  28. # master ip means master node ip of cluster
  29. MASTER_IP="x.x.x.x"
  31. # +optional
  32. # KUBECUBE_HOST must be set when as a member cluster to
  33. # join pivot cluster, the value is pivot node ip
  34. KUBECUBE_HOST="y.y.y.y"
  36. # zone has two choice
  37. # 1. "cn" : in mainland
  38. # 2. "others" : out of mainland
  39. ZONE="cn"
  41. # k8s version you want to install
  42. KUBERNETES_VERSION="1.20.9"
  44. # +optional
  45. # the user who can access master node, it can be empty
  46. # when NODE_MODE="master" or "control-plane-master"
  47. MASTER_USER="root"
  49. # +optional
  50. # must be empty when ACCESS_PRIVATE_KEY_PATH set
  51. # password for master user to access master node
  52. ACCESS_PASSWORD=""
  54. # +optional
  55. # must be empty when ACCESS_PASSWORD set
  56. # ACCESS_PRIVATE_KEY for master user to access master node
  57. ACCESS_PRIVATE_KEY_PATH="/root/.ssh/id_rsa"

方式二：纳管已有集群

添加已有集群需要从 console 页面获取添加集群的定制脚本

在 console 页面中获取添加集群的脚本

add-member-cluster

使用脚本添加集群

在集群的 node 机器上，使用从 console 中下载的脚本，该机器需要能够执行 kubectl

  1. /bin/bash add_cluster.sh

等待集群添加完成

add-cluster

在 console 中确认新集群

check-cluster
