kubernetes(k8s)集群安装calico

 

添加hosts解析

cat /etc/hosts
10.39.7.51 k8s-master-51
10.39.7.57 k8s-master-57
10.39.7.52 k8s-master-52

下载calico

wget http://docs.projectcalico.org/v3.2/getting-started/kubernetes/installation/hosted/calico.yaml

下载所需镜像

# 建议下载后 推到自己的镜像仓库
[root@k8s-master-51 ~]# cat calico.yaml |grep image
image: quay.io/calico/node:v3.2.4 image: quay.io/calico/cni:v3.2.4 image: quay.io/calico/kube-controllers:v3.2.4 

配置etcd的ip

etcd_endpoints: "https://10.39.7.51:2379,https://10.39.7.52:2379,https://10.39.7.57:2379"

根据注释添加相关值

 # If you're using TLS enabled etcd uncomment the following.
  # You must also populate the Secret below with these files.
  etcd_ca: "/calico-secrets/etcd-ca"   # "/calico-secrets/etcd-ca"
  etcd_cert: "/calico-secrets/etcd-cert" # "/calico-secrets/etcd-cert" etcd_key: "/calico-secrets/etcd-key # "/calico-secrets/etcd-key" 

因使用青云关系 需调整mtu值

veth_mtu: "1340"

将etcd 和ca 证书用base64加密添加到calico.yaml 的相关位置

apiVersion: v1
kind: Secret
type: Opaque
metadata:
  name: calico-etcd-secrets namespace: kube-system data: etcd-key: (cat /etc/kubernetes/ssl/etcd-key.pem | base64 | tr -d '\n') etcd-cert: (cat /etc/kubernetes/ssl/etcd.pem | base64 | tr -d '\n') etcd-ca: (cat /etc/kubernetes/ssl/ca.pem | base64 | tr -d '\n') 

修改calico.yaml中的CALICO_IPV4POOL_CIDR 下的value值

- name: CALICO_IPV4POOL_CIDR
    value: "10.253.0.0/18"

安装calico

kubectl apply -f calico.yaml 

修改kubelet.service 配置网络插件
