- 服务器芯片:Kunpeng-920
- 操作系统:麒麟V10 SP2/SP3 aarch64
- Docker: 24.0.7
- Harbor: v2.7.1
- KubeSphere:v3.3.1
- Kubernetes:v1.22.12
- KubeKey: v2.3.1
本文介绍
本文详解在麒麟V10 aarch64架构服务器上,如何实现KubeSphere和Kubernetes集群的制品和离线部署。借助KubeSphere开发的KubeKey工具,我们成功在三台服务器上实现了高可用模式的最小化Kubernetes集群及KubeSphere部署。
KubeSphere 和 Kubernetes 在 ARM 架构 和 X86 架构的服务器上部署,最大的区别在于所有服务使用的容器镜像架构类型的不同,KubeSphere 开源版对于 ARM 架构的默认支持可以实现 KubeSphere-Core 功能,即可以实现最小化的 KubeSphere 和完整的 Kubernetes 集群的部署。
当启用了 KubeSphere 可插拔组件时,会遇到个别组件部署失败的情况,需要我们手工替换官方或是第三方提供的 ARM 版镜像或是根据官方源码手工构建 ARM 版镜像。如果需要实现开箱即用及更多的技术支持,则需要购买企业版的 KubeSphere。
1.1 确认操作系统配置
在执行下文的任务之前,先确认操作系统相关配置。
- 操作系统类型
[root@localhost ~]# cat /etc/os-release
Kylin Linux Advanced Server V10 (Halberd)
ID="kylin"
VERSION_ID="V10"
PRETTY_NAME="Kylin Linux Advanced Server V10 (Halberd)"
ANSI_COLOR="0;31"
- 操作系统内核
优化后的文章内容如下:[root@node1 ~]# uname -a,Linux 4.19.90-52.22.v2207.ky10.aarch64
- 服务器 CPU 信息
[root@node1 ~]# lscpuArchitecture: aarch64CPU op-mode(s): 64-bitByte Order: Little EndianCPU(s): 32On-line CPU(s) list: 0-31Thread(s) per core: 1Core(s) per socket: 1Socket(s): 32NUMA node(s): 2Vendor ID: HiSiliconModel: 0Model name: Kunpeng-920Stepping: 0x1BogoMIPS: 200.00NUMA node0 CPU(s): 0-15NUMA node1 CPU(s): 16-31Vulnerability Itlb multihit: Not affectedVulnerability L1tf: Not affectedVulnerability Mds: Not affectedVulnerability Meltdown: Not affectedVulnerability Spec store bypass: Not affectedVulnerability Spectre v1: Mitigation; __user pointer sanitizationVulnerability Spectre v2: Not affectedVulnerability Srbds: Not affectedVulnerability Tsx async abort: Not affectedFlags: fp asimd evtstrm aes pmull sha1 sha2 crc32 atomics fphp asimdhp cpuid asimdrdm jscvt fcma dcpop asimddp asimdfhm
2. 安装k8s依赖服务
利用可联网的部署节点创建离线资源包。由于Harbor官方不支持ARM,我们首先在线安装KubeSphere。稍后,根据KubeKey生成的文件作为伪制品进行部署。因此,在192.168.200.7服务器上以单节点形式部署KubeSphere。
以下为多阶段部署,目的是方便制作离线安装包
2.1 部署docker和docker-compose
具体可参考以下文章第一部分
天行1st,公众号:编码如写诗鲲鹏+欧拉部署KubeSphere3.4
这里采用制作好的安装包形式,直接安装,解压后执行其中的install.sh
2.2 部署harbor
上传安装包后解压后执行其中的install.sh
1. 确保标题简洁明了,能够准确反映文章的主题。
2. 在文章开头用简短的段落概括文章的主要内容,吸引读者继续阅读。
3. 使用数据和事实支持观点,使文章更具说服力。
4. 保持文章结构清晰,每个段落只讨论一个主要观点。
5. 使用简洁、明了的语言,避免冗长和复杂的句子。
6. 在文章结尾进行总结,强调文章的核心观点。
2.3 下载麒麟系统k8s依赖包
mkdir -p /root/kubesphere/k8s-init# 该命令将下载相关依赖到/root/kubesphere/k8s-init目录yum -y install openssl socat conntrack ipset ebtables chrony ipvsadm --downloadonly --downloaddir /root/kubesphere/k8s-init# 编写安装脚本cat install.sh#!/bin/bash#
rpm -ivh *.rpm --force --nodeps
# 打成压缩包,方便离线部署使用tar -czvf k8s-init-Kylin_V10-arm.tar.gz ./k8s-init/*
2.4 下载ks相关镜像
下载kubesphere3.3.1所需要的arm镜像

3. 使用kk部署kubesphere
3.1 移除麒麟系统自带的podman
Podman是麒麟系统自带的轻量级容器引擎,为了避免与Docker产生冲突,建议直接卸载。这将有助于确保后续的coredns/nodelocaldns正常启动,同时避免Docker权限问题。
yum remove podman
3.2 下载kubekey
请下载 kubekey-v2.3.1-linux-arm64.tar.gz。KubeKey 发行页面(链接)可查看具体版本号。
- 方式一
请参考以下优化后的文章:
```
cd kubesphere/
export KKZONE=cn
curl -sfL https://get-kk.kubesphere.io/v2.3.1/kubekey-v2.3.1-linux-arm64.tar.gz | tar xzf -
```
以上代码实现了在 `kubesphere` 目录下创建一个名为 `kubesphere` 的文件夹,并设置中文区域下载。然后,通过执行 curl 命令从 GitHub 获取最新版的 `kubekey`,并将其解压到当前目录中。这样可以方便地获取并安装 KubeSphere 的最新版本。请注意,由于网络限制,有时需要多次执行该命令才能成功下载。
- 方式二
在本地电脑上,直接访问GitHub Releases · kubesphere/kubekey 下载KubeKey。
上传至服务器/root/kubesphere目录解压
3.3 生成集群创建配置文件
本示例中,创建集群配置文件,选择 KubeSphere v3.3.1 和 Kubernetes v1.22.12。
```
/kk create config -f kubesphere-v331-v12212.yaml --with-kubernetes v1.22.12 --with-kubesphere v3.3.1
```
在成功执行命令后,当前目录将生成名为 kubesphere-v331-v12212.yaml 的配置文件。
本文展示如何配置3个节点,包括control-plane、etcd和worker,提高系统性能。
请优化以下文章内容:编辑kubesphere-v331-v12212.yaml配置文件,主要调整Cluster和ClusterConfiguration两部分的相关设置。
请调整"Cluster"小节中的"hosts"和"roleGroups"等设置,详细修改说明如下。
- hosts:指定节点的 IP、ssh 用户、ssh 密码、ssh 端口。特别注意:一定要手工指定 arch: arm64,否则部署的时候会安装 X86 架构的软件包。
在 hosts 文件中,设置节点的 IP、SSH 用户名、密码和端口。请注意:务必手动指定 arch 为 arm64,否则部署时将安装 X86 架构的软件包。 - 在Kubernetes中,通过roleGroups可以实现将3个etcd和control-plane节点设置为复用相同机器的worker节点。这样可以提高集群的可扩展性和资源利用率。
- domain:自定义了一个 opsman.top
- containerManager:使用了 containerd
- 请将 `storage.openebs.basePath` 配置项设置为默认存储路径 `/data/openebs/local`,以便在 OpenEBS 中使用。
修改后的示例如下:

3.4 执行安装
```
请使用以下命令创建集群:kk create cluster -f kubesphere-v331-v122123.yaml
```
安装kubesphere的初衷在于在过程中自动生成kubekey文件夹,从而一次性下载并保存Kubernetes所需的所有依赖。此后,我们主要通过离线使用kubekey文件夹和相应的脚本来部署系统,以此替代之前的制品。
4. 制作离线部署资源
4.1 导出k8s基础依赖包
```
# 安装所需软件包
yum -y install openssl socat conntrack ipset ebtables chrony ipvsadm --downloadonly --downloaddir /root/kubesphere/k8s-init
# 将安装文件打包成压缩包
tar -czvf k8s-init-Kylin_V10-arm.tar.gz /root/kubesphere/k8s-init/*
```
4.2 导出ks需要的镜像
导出ks相关的镜像至ks3.3.1-images.tar
docker save -o ks3.3.1-images.tar dockerhub.kubekey.local/kubesphereio/kube-controllers:v3.27.3 dockerhub.kubekey.local/kubesphereio/cni:v3.27.3 dockerhub.kubekey.local/kubesphereio/pod2daemon-flexvol:v3.27.3 dockerhub.kubekey.local/kubesphereio/node:v3.27.3 dockerhub.kubekey.local/kubesphereio/ks-console:v3.3.1 dockerhub.kubekey.local/kubesphereio/alpine:3.14 dockerhub.kubekey.local/kubesphereio/k8s-dns-node-cache:1.22.20 dockerhub.kubekey.local/kubesphereio/ks-controller-manager:v3.3.1 dockerhub.kubekey.local/kubesphereio/ks-installer:v3.3.1 dockerhub.kubekey.local/kubesphereio/ks-apiserver:v3.3.1 dockerhub.kubekey.local/kubesphereio/openpitrix-jobs:v3.3.1 dockerhub.kubekey.local/kubesphereio/kube-apiserver:v1.22.12 dockerhub.kubekey.local/kubesphereio/kube-proxy:v1.22.12 dockerhub.kubekey.local/kubesphereio/kube-controller-manager:v1.22.12 dockerhub.kubekey.local/kubesphereio/kube-scheduler:v1.22.12 dockerhub.kubekey.local/kubesphereio/provisioner-localpv:3.3.0 dockerhub.kubekey.local/kubesphereio/linux-utils:3.3.0 dockerhub.kubekey.local/kubesphereio/kube-state-metrics:v2.5.0 dockerhub.kubekey.local/kubesphereio/fluent-bit:v2.0.6 dockerhub.kubekey.local/kubesphereio/prometheus-config-reloader:v0.55.1 dockerhub.kubekey.local/kubesphereio/prometheus-operator:v0.55.1 dockerhub.kubekey.local/kubesphereio/thanos:v0.25.2 dockerhub.kubekey.local/kubesphereio/prometheus:v2.34.0 dockerhub.kubekey.local/kubesphereio/fluentbit-operator:v0.13.0 dockerhub.kubekey.local/kubesphereio/node-exporter:v1.3.1 dockerhub.kubekey.local/kubesphereio/kubectl:v1.22.0 dockerhub.kubekey.local/kubesphereio/notification-manager:v1.4.0 dockerhub.kubekey.local/kubesphereio/notification-tenant-sidecar:v3.2.0 dockerhub.kubekey.local/kubesphereio/notification-manager-operator:v1.4.0 dockerhub.kubekey.local/kubesphereio/alertmanager:v0.23.0 dockerhub.kubekey.local/kubesphereio/kube-rbac-proxy:v0.11.0 dockerhub.kubekey.local/kubesphereio/docker:19.03 dockerhub.kubekey.local/kubesphereio/metrics-server:v0.4.2 dockerhub.kubekey.local/kubesphereio/pause:3.5 dockerhub.kubekey.local/kubesphereio/configmap-reload:v0.5.0 dockerhub.kubekey.local/kubesphereio/snapshot-controller:v4.0.0 dockerhub.kubekey.local/kubesphereio/mc:RELEASE.2019-08-07T23-14-43Z dockerhub.kubekey.local/kubesphereio/minio:RELEASE.2019-08-07T01-59-21Z dockerhub.kubekey.local/kubesphereio/kube-rbac-proxy:v0.8.0 dockerhub.kubekey.local/kubesphereio/coredns:1.8.0 dockerhub.kubekey.local/kubesphereio/defaultbackend-amd64:1.4 dockerhub.kubekey.local/kubesphereio/redis:5.0.14-alpine dockerhub.kubekey.local/kubesphereio/k8s-dns-node-cache:1.15.12 dockerhub.kubekey.local/kubesphereio/node:v3.23.2 dockerhub.kubekey.local/kubesphereio/pod2daemon-flexvol:v3.23.2 dockerhub.kubekey.local/kubesphereio/cni:v3.23.2 dockerhub.kubekey.local/kubesphereio/kube-controllers:v3.23.2 dockerhub.kubekey.local/kubesphereio/haproxy:2.3 dockerhub.kubekey.local/kubesphereio/busybox:latest dockerhub.kubekey.local/kubesphereio/opensearch:2.6.0 dockerhub.kubekey.local/kubesphereio/fluent-bit:v2.0.6
压缩
gzip ks3.3.1-images.tar
4.3 导出kubesphere文件夹
[root@node1 ~]# cd /root/kubesphere[root@node1 kubesphere]# lscreate_project_harbor.sh docker-24.0.7-arm.tar.gz fluent-bit-daemonset.yaml harbor-arm.tar.gz harbor.tar.gz install.sh k8s-init-Kylin_V10-arm.tar.gz ks3.3.1-images.tar.gz ks3.3.1-offline push-images.sh
tar -czvf kubeshpere.tar.gz ./kubesphere/*
编写install.sh用于后续一键离线安装kk
#!/usr/bin/env bashread -p "请先修改机器配置文件ks3.3.1-offline/kubesphere-v331-v12212.yaml中相关IP地址,是否已修改(yes/no)" B do_k8s_init(){ echo "--------开始进行依赖包初始化------" yum remove podman -y tar zxf k8s-init-Kylin_V10-arm.tar.gz cd k8s-init && ./install.sh cd - rm -rf k8s-init}

if [ "$B" = "yes" ] || [ "$B" = "y" ]; then do_k8s_init install_docker install_harbor install_kselse echo "请先配置集群配置文件" exit 1fi
5. 离线环境安装k8s和kubesphere
5.1 卸载podman和安装k8s依赖
所有节点都需要操作,
上传K8s-init-Kylin_V10-arm.tar.gz并解压后,执行install.sh。若单节点离线部署,可直接进入下一步。
yum remove podman -y
5.2 安装ks集群
