calico安装

配置 NetworkManager

Vim /etc/NetworkManager/conf.d/calico.conf

[keyfile]
unmanaged-devices=interface-name:cali*;interface-name:tunl*;interface-name:vxlan.calico;interface-name:vxlan-v6.calico;interface-name:wireguard.cali;interface-name:wg-v6.cali

libseccomp版本高于2.4，否则安装网络插件会报错

yum -y install https://mirrors.tuna.tsinghua.edu.cn/centos/8-stream/BaseOS/x86_64/os/Packages/libseccomp-2.5.1-1.el8.x86_64.rpm

下载operator资源清多文件

wget https://docs.projectcalico.org/manifests/tigera-operator.yaml

应用资源清多文件，创建operator

kubectl create -f tigera-operator.yaml

通过自定义资源方式安装

wget https://docs.projectcalico.org/manifests/custom-resources.yaml

关键!!

修改文件第13行，修改为使用kubeadm init ----pod-network-cidr对应的IP地址段,

networking:
  dnsDomain: cluster.local
  podSubnet: 10.224.0.0/16
  serviceSubnet: 10.96.0.0/12

vim custom-resources.yaml

...... 11 ipPools: 12 - blockSize: 26 13 cidr: 10.244.0.0/16 14 encapsulation: VXLANCrossSubnet ......

应用资源清多文件

kubectl apply -f custom-resources.yaml

监视calico-sysem命名空间中pod运行情况

watch kubectl get pods -n calico-system

Wait until each pod has the STATUS of Running.

删除 master 上的 taint

kubectl taint nodes --all node-role.kubernetes.io/master-

kubectl taint nodes node node-role.kubernetes.io/control-plane:NoSchedule-

已经全部运行

kubectl get pods -n calico-system

NAME READY STATUS RESTARTS AGE calico-kube-controllers-666bb9949-dzp68 1/1 Running 0 11m calico-node-jhcf4 1/1 Running 4 11m calico-typha-68b96d8d9c-7qfq7 1/1 Running 2 11m

查看kube-system命名空间中coredns状态，处于Running状态表明联网成功。

kubectl get pods -n kube-system

NAME READY STATUS RESTARTS AGE coredns-558bd4d5db-4jbdv 1/1 Running 0 113m coredns-558bd4d5db-pw5x5 1/1 Running 0 113m etcd-master01 1/1 Running 0 113m kube-apiserver-master01 1/1 Running 0 113m kube-controller-manager-master01 1/1 Running 4 113m kube-proxy-kbx4z 1/1 Running 0 113m kube-scheduler-master01 1/1 Running 3 113m

方法二 使用helm 安装

https://docs.tigera.io/calico/latest/getting-started/kubernetes/helm

helm repo add projectcalico https://docs.tigera.io/calico/charts

helm pull projectcalico/tigera-operator

tar xvf tigera-operator-*.tgz

编辑value cidr


installation:
  kubernetesProvider: ""
  cni:
    type: Calico
  calicoNetwork:
    bgp: Disabled
    ipPools:
    - cidr: 10.244.0.0/16
      encapsulation: VXLAN
      
apiServer:
  enabled: true
  
kubeletVolumePluginPath: /var/lib/kubelet

helm install calico projectcalico/tigera-operator --version v3.27.3 -f values.yaml --namespace tigera-operator

5.8.2 calico客户端安装

下载二进制文件

curl -L https://github.com/projectcalico/calico/releases/download/v3.21.4/calicoctl-linux-amd64 -o calicoctl

安装calicoctl

mv calicoctl /usr/bin/

为calicoctl添加可执行权限

chmod +x /usr/bin/calicoctl

查看添加权限后文件

ls /usr/bin/calicoctl

/usr/bin/calicoctl

查看calicoctl版本

calicoctl version

Client Version: v3.21.4 Git commit: 220d04c94 Cluster Version: v3.21.4 Cluster Type: typha,kdd,k8s,operator,bgp,kubeadm

通过~/.kube/config连接kubernetes集群，查看已运行节点

DATASTORE_TYPE=kubernetes KUBECONFIG=~/.kube/config calicoctl get nodes

NAME master01
