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
