保姆式安装 DCE 5.0 社区版

作者:SAMZONG

本文完成了从 0 到 1 的 DCE 5.0 社区版安装,包含了 K8s 集群、依赖项、网络、存储等细节及更多注意事项。

现阶段版本迭代较快,本文的安装方式可能与最新版有所差异,请以产品文档的安装说明为准。

集群规划

计划使用 3 台 UCloud 的 VM,配置均为 8 核 16G。

角色 主机名 操作系统 IP 配置
master master-k8s-com CentOS 7.9 10.23.245.63 8 核 16G 300GB
node01 node01-k8s-com CentOS 7.9 10.23.104.173 8 核 16G 300GB
node02 node02-k8s-com CentOS 7.9 10.23.112.244 8 核 16G 300GB

计划采用的集群组件为:

  • Kubernetes 1.24.8
  • CRI containerd
  • CNI Calico
  • StorageClass HwameiStior

节点系统优化

安装前先对 3 个节点做了一些优化。

  1. 配置主机名

    hostnamctl set-hostname master-k8s-com
    
  2. 添加 /etc/hosts 配置

    cat <<EOF | tee /etc/hosts
    10.23.245.63    master-k8s-com
    10.23.104.173   node01-k8s-com
    10.23.112.244   node02-k8s-com
    EOF
    
  3. 禁用 Swap

    swapoff -a
    sed -i '/ swap / s/^/#/' /etc/fstab
    
  4. 禁用 SElinux

    setenforce 0
    sed -i 's/^SELINUX=enforcing$/SELINUX=permissive/' /etc/selinux/config
    
  5. 关闭防火墙

    systemctl stop firewalld
    systemctl disable firewalld
    
  6. 允许 iptables 检查桥接流量

    加载 br_netfilter 模块:

    1
    2
    3
    4
    5
    6
    cat <<EOF | tee /etc/modules-load.d/kubernetes.conf
    br_netfilter
    EOF
    
    # 加载模块
    modprobe br_netfilter
    

    修改 net.bridge.bridge-nf-call-iptables 设置为 1:

    1
    2
    3
    4
    5
    6
    7
    cat <<EOF | tee /etc/sysctl.d/kubernetes.conf
    net.bridge.bridge-nf-call-ip6tables = 1
    net.bridge.bridge-nf-call-iptables = 1
    EOF
    
    # 刷新配置
    sysctl --system
    

安装 K8s

开始安装容器运行时、K8s 系统组件,初始化 Master 节点,加入 Worker 节点,安装网络 CNI。

安装容器运行时

本例为了后续方便拉镜像,同时安装了 Docker 和 containerd,DCE 5.0 实际用的是 containerd。

  1. 安装 Docker 的软件源

    sudo yum install -y yum-utils
    sudo yum-config-manager \
        --add-repo \
        https://download.docker.com/linux/centos/docker-ce.repo
    
  2. 安装 Docker 和 containerd

    sudo yum -y install docker-ce docker-ce-cli containerd.io
    
  3. 修改 Docker 的配置

    1
    2
    3
    4
    5
    6
    7
    sudo touch /etc/docker/daemon.json
    
    cat <<EOF | tee /etc/docker/daemon.json
    {
      "exec-opts": ["native.cgroupdriver=systemd"]
    }
    EOF
    
  4. 修改 containerd 的配置

    4
    5
    6
    7
    8
    9
    # 清理配置文件
    sudo rm -f /etc/containerd/config.toml
    
    # 初始化配置
    sudo containerd config default | sudo tee /etc/containerd/config.toml
    
    # 更新配置文件内容
    sed -i 's/SystemdCgroup\ =\ false/SystemdCgroup\ =\ true/' /etc/containerd/config.toml
    sed -i 's/k8s.gcr.io\/pause/registry.cn-hangzhou.aliyuncs.com\/google_containers\/pause/g' /etc/containerd/config.toml
    
  5. 启动服务配置

    1
    2
    3
    sudo systemctl daemon-reload
    sudo systemctl enable --now docker
    sudo systemctl enable --now containerd
    
  6. 检查配置成功

    sudo systemctl status docker containerd
    sudo docker info
    

安装 K8s 系统组件

  1. 安装 Kubernetes 软件源

    这里采用国内阿里云的源,具有加速效果。

    2
    3
    4
    5
    6
    7
    8
    9
    cat <<EOF | sudo tee /etc/yum.repos.d/kubernetes.repo
    [kubernetes]
    name=Kubernetes
    baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/
    enabled=1
    gpgcheck=1
    repo_gpgcheck=1
    gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
    EOF
    
  2. 安装 Kubernetes 组件

    1
    2
    3
    export K8sVersion=1.24.8
    sudo yum install -y kubelet-$K8sVersion kubeadm-$K8sVersion
    sudo yum install -y kubectl-$K8sVersion  # (1)
    
    1. 可以仅在 Master 节点安装
  3. 启动 kubelet系统服务

    sudo systemctl enable --now kubelet
    

此时启动后发现服务状态异常,会检查集群配置,因为没有配置会不断地重启,不影响后续操作。

初始化 Master 节点

注意规划集群主节点配置,初始化主节点时,规划网络配置。

指定对应的 K8s 的版本,注意与安装时的配置保持一致:

sudo kubeadm init --kubernetes-version=v1.24.8 \
 --image-repository=registry.cn-hangzhou.aliyuncs.com/google_containers \
 --pod-network-cidr 10.11.0.0/16 \

Your Kubernetes control-plane has initialized successfully!

To start using your cluster, you need to run the following as a regular user:

  mkdir -p $HOME/.kube
  sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
  sudo chown $(id -u):$(id -g) $HOME/.kube/config

Alternatively, if you are the root user, you can run:

  export KUBECONFIG=/etc/kubernetes/admin.conf

You should now deploy a pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
  https://kubernetes.io/docs/concepts/cluster-administration/addons/

Then you can join any number of worker nodes by running the following on each as root:

kubeadm join 10.23.245.63:6443 --token djdsj2.sj23js90213j323 \
        --discovery-token-ca-cert-hash sha256:ewuosdjk2390rjertw32p32j43p25a70298db818ajsdjk1293jk23k23201934h

加入 Worker 节点

需确保完成了上述步骤:节点系统优化、安装容器运行时、安装 K8s 系统组件,并且成功初始化 Master 节点。

运行以下命令加入 Worker 节点:

kubeadm join 10.23.245.63:6443 --token djdsj2.sj23js90213j323 \
  --discovery-token-ca-cert-hash sha256:ewuosdjk2390rjertw32p32j43p25a70298db818ajsdjk1293jk23k23201934h

查看新加的 Worker 节点:

kubectl get nodes

输出类似于:

NAME               STATUS   ROLES           AGE   VERSION
master01-k8s-com   Ready    control-plane   9h    v1.24.8
node01-k8s-com     Ready    <none>          9h    v1.24.8
node02-k8s-com     Ready    <none>          9h    v1.24.8

                            validator will check for it.'
                          items:
                            description: 'HTTPPath specifies an HTTP path to match.
                              It may be either of the form: exact: <path>: which matches

                              the path prefix'
                            properties:
                              exact:
                                type: string

                            a value of 8```

执行初始化 Calico 命令:

kubectl apply -f calico.yaml

安装 Helm

本例使用了 Helm 3,注意安装脚本会下载最新版本:

curl -fsSL -o get_helm.sh https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3
chmod 700 get_helm.sh
./get_helm.sh

安装 StorageClass

Tip

注意,HwameiStor 需要使用未格式化文件系统的裸盘直接来进行存储管理

默认安装时将 K8s localdisk 作为默认存储,本例采用开源项目 HwameiStor 用作本地磁盘管理。

  1. 下载并解压 HwameiStor Repo

    1
    2
    3
    helm repo add hwameistor http://hwameistor.io/hwameistor
    helm repo update hwameistor
    helm pull hwameistor/hwameistor --untar
    
  2. 安装 HwameiStor

    使用镜像仓库安装,要切换镜像仓库的镜像,请使用 --set 更改这两个参数值: global.k8sImageRegistryglobal.hwameistorImageRegistry

    如果无法访问默认的镜像仓库 quay.ioghcr.io,请尝试使用 DaoCloud 提供的镜像源 quay.m.daocloud.ioghcr.m.daocloud.io

    1
    2
    3
    4
    helm install hwameistor ./hwameistor \
      -n hwameistor --create-namespace \
      --set global.k8sImageRegistry=k8s-gcr.m.daocloud.io \
      --set global.hwameistorImageRegistry=ghcr.m.daocloud.io
    
  3. 检查 HwameiStor 的全部 Pod 状态

    kubectl -n hwameistor get pod
    

    输出类似于:

    NAME                                                       READY   STATUS
    hwameistor-local-disk-csi-controller-665bb7f47d-6227f      2/2     Running
    hwameistor-local-disk-manager-5ph2d                        2/2     Running
    hwameistor-local-disk-manager-jhj59                        2/2     Running
    hwameistor-local-disk-manager-k9cvj                        2/2     Running
    hwameistor-local-disk-manager-kxwww                        2/2     Running
    hwameistor-local-storage-csi-controller-667d949fbb-k488w   3/3     Running
    hwameistor-local-storage-csqqv                             2/2     Running
    hwameistor-local-storage-gcrzm                             2/2     Running
    hwameistor-local-storage-v8g7t                             2/2     Running
    hwameistor-local-storage-zkwmn                             2/2     Running
    hwameistor-scheduler-58dfcf79f5-lswkt                      1/1     Running
    hwameistor-webhook-986479678-278cr                         1/1     Running
    

    local-disk-manager 和 local-storage 都是 DaemonSet。在每个 K8s 节点上都应该有一个 DaemonSet Pod。

    等到全部状态正常后,可进行后续操作,检查 StorageClass

    kubectl get storageclass hwameistor-storage-lvm-hdd
    

    输出类似于:

    NAME                                   PROVISIONER         RECLAIMPOLICY
    hwameistor-storage-lvm-hdd (default)   lvm.hwameistor.io   Delete
    
  4. 检查 localdisknodes,默认在使用的磁盘 PHASEBound

    kubectl get localdisknodes
    

    输出类似于:

    NAME               NODEMATCH          PHASE
    master01-k8s-com   master01-k8s-com   Bound
    node01-k8s-com     node01-k8s-com     Bound
    node02-k8s-com     node02-k8s-com     Bound
    
  5. 检查 localdisks,默认在使用的磁盘 PHASEBound

    kubectl get localdisks
    

    输出类似于:

    NAME                   NODEMATCH          CLAIM              PHASE
    master01-k8s-com-vda   master01-k8s-com                      Bound
    master01-k8s-com-vdb   master01-k8s-com   master01-k8s-com   Bound
    node01-k8s-com-vda     node01-k8s-com                        Bound
    node01-k8s-com-vdb     node01-k8s-com     node01-k8s-com     Bound
    node02-k8s-com-vda     node02-k8s-com                        Bound
    node02-k8s-com-vdb     node02-k8s-com     node02-k8s-com     Bound
    
  6. 设置默认的 StorageClass

    storageclasses 增加标识为默认的 annotations

    kubectl patch storageclasses.storage.k8s.io hwameistor-storage-lvm-hdd -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'
    
  7. 创建存储池,注意替换对应的 nodeName

    1
    2
    3
    4
    helm template ./hwameistor \
      -s templates/post-install-claim-disks.yaml \
      --set storageNodes='{master01-k8s-com,node01-k8s-com,node02-k8s-com}' \
      | kubectl apply -f -
    

    创建成功后,查看本地磁盘的 ldc,应该全部是 Bound

    kubectl get ldc
    

安装 Metrics server

接下来需要安装 metrics-server,方便后续使用 Insight 可观测性模块。 将以下 YAML 保存为 metrics-server.yaml

安装 DCE 5.0 社区版

现在一切准备就绪,开始安装 DCE 5.0 社区版。

安装基础依赖

DCE 已经提供了一键安装的离线工具依赖包,经过测试能够比较稳定地运行在 CentOS 7CentOS 8 上。 如果您也是这两个操作系统,可以直接运行下面的命令。

1
2
3
curl -LO https://proxy-qiniu-download-public.daocloud.io/DaoCloud_Enterprise/dce5/install_prerequisite.sh
chmod +x install_prerequisite.sh
sudo bash install_prerequisite.sh online community

当然也可以选择手动安装这些依赖项:

  • podman
  • helm ≥ 3.9.4
  • skopeo ≥ 1.9.2
  • kind
  • kubectl ≥ 1.22.0
  • yq ≥ 4.27.5
  • minio client

下载 dce5-installer

注意,需要在 Master 节点执行 dce5-installer 的安装,建议直接下载此 installer

下载并解压 tar 包之后,假定 VERSION 为 v0.3.28:

1
2
3
export VERSION=v0.3.28
curl -Lo ./dce5-installer  https://proxy-qiniu-download-public.daocloud.io/DaoCloud_Enterprise/dce5/dce5-installer-$VERSION
chmod +x dce5-installer

如果 proxy-qiniu-download-public.daocloud.io 链接失效,可使用 qiniu-download-public.daocloud.io

设置配置文件 [可选]

将以下配置文件内容保存为 clusterConfig.yaml,如果使用 NodePort 的方式安装则不需要指定该配置文件。

clusterConfig.yaml
apiVersion: provision.daocloud.io/v1alpha1
kind: ClusterConfig
spec:
 loadBalancer: metallb
 istioGatewayVip: 10.6.229.10/32  # (1)
 insightVip: 10.6.229.11/32  # (2)
  1. 这是 Istio gateway 的 VIP,也是 DCE 5.0 控制台的浏览器访问 IP
  2. 这是全局服务集群的 Insight-Server 采集子集群监控指标的网络路径用的 VIP

如果使用配置文件,注意需要事先安装 MetaLB,这一部分需要自行完成。

执行安装

根据实际情况,运行以下命令之一:

  • 无配置文件时

    ./dce5-installer install-app
    
  • 指定配置文件和 loadBalancer 时

    ./dce5-installer install-app -c clusterConfig.yaml
    

安装完成

如果看到下方的页面,说明安装成功了;默认账号密码为:admin/changeme

安装成功

重定向 Portal 反向代理

通常安装后的集群访问地址是一个内网地址。 当需要集群页面开放到公网访问时,会发现登录页会自动重定向内网地址,这是因为 DCE 5.0 反向代理服务器地址默认是安装时的配置,需要进行以下修改。

  1. 设置环境变量

    # 反向代理地址
    export DCE_PROXY="https://domain:port"
    
    # helm --set 参数备份文件
    export GHIPPO_VALUES_BAK="ghippo-values-bak.yaml"
    
    # 获取当前 ghippo 全局管理的版本号
    export GHIPPO_HELM_VERSION=$(helm get notes ghippo -n ghippo-system | grep "Chart Version" | awk -F ': ' '{ print $2 }')
    
  2. 更新 Helm repo

    helm repo update ghippo
    
  3. 备份 --set 参数

    helm get values ghippo -n ghippo-system -o yaml > ${GHIPPO_VALUES_BAK}
    
  4. 使用 vim 命令编辑并保存

    vim ${GHIPPO_VALUES_BAK}
    

    只需修改一行:

    USER-SUPPLIED VALUES:
    ...
    global:
      ...
      reverseProxy: ${DCE_PROXY} # (1)
    
    1. 只需要修改这一行

    注意这里需要把 ${DCE_PROXY} 替换为实际访问地址;需要配置完整的路径,包含 https 或 http、IP 或域名以及端口;如果是默认 80/443,则可以省略。

  5. 使用 heml upgrade 更新配置

    helm upgrade ghippo ghippo/ghippo \
      -n ghippo-system \
      -f ${GHIPPO_VALUES_BAK} \
      --version ${GHIPPO_HELM_VERSION}
    
  6. 使用 kubectl 重启全局管理 Pod,使配置生效

    kubectl rollout restart deploy/ghippo-apiserver -n ghippo-system
    kubectl rollout restart statefulset/ghippo-keycloak -n ghippo-system
    
  7. 登录 DCE

    登录

  8. DCE 登录成功

    成功登录
