k8s-calico

1 按照官方指导文档安装

https://docs.projectcalico.org/v2.6/getting-started/kubernetes/installation/integration

注意事项：

1.1 master需要配置环境变量

ETCD_ENDPOINTS=http://192.168.56.110：2379
1.2 node上面的配置文件

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

ubuntu@k8s-node:~$ cat /etc/cni/net.d/10-calico.conf {     "name": "calico-k8s-network",     "cniVersion": "0.1.0",     "type": "calico",     "etcd_endpoints": "http://192.168.56.110:2379",     "log_level": "info",     "ipam": {         "type": "calico-ipam",         "assign_ipv4": "true",         "ipv4_pools": ["10.1.0.0/16"]     },     "policy": {         "type": "k8s"     },     "kubernetes": {         "kubeconfig": "/var/lib/kubelet/kubeconfig"     } }

　　1.3 需要添加地址池

?

ubuntu@k8s-master:~$ cat ippool.yaml apiVersion: v1 kind: ipPool metadata:   cidr: "10.1.0.0/16" spec:   ipip:     enabled: true     mode: cross-subnet   nat-outgoing: true   disabled: false ubuntu@k8s-master:~$ calicoctl apply -f ippool.yaml

　　

 1.4 修改kubelet的配置，使其使用calico

 

?

ubuntu@k8s-node:~$ sudo cat /etc/kubernetes/kubelet #KUBELET_ADDRESS="--address=127.0.0.1" KUBELET_HOSTNAME="--hostname-override=192.168.56.111" #KUBELET_API_SERVER="--api-servers=http://192.168.56.110:8080" # pod infrastructure container KUBELET_POD_INFRA_CONTAINER="--pod-infra-container-image=registry.access.redhat.com/rhel7/pod-infrastructure:latest" KUBELET_ARGS="--enable-server=true --enable-debugging-handlers=true --fail-swap-on=false --kubeconfig=/var/lib/kubelet/kubeconfig --network-plugin=cni  --cni-conf-dir=/etc/cni/net.d  --cni-bin-dir=/opt/cni/bin"

　1.5 calico-kube-controller 容器，需要在master上面创建

?

ubuntu@k8s-master:~$ cat a apiVersion: extensions/v1beta1 kind: Deployment metadata:   name: calico-policy-controller   namespace: kube-system   labels:     k8s-app: calico-policy spec:   replicas: 1   strategy:     type: Recreate   template:     metadata:       name: calico-policy-controller       namespace: kube-system       labels:         k8s-app: calico-policy     spec:       hostNetwork: true       containers:         - name: calico-policy-controller           image: quay.io/calico/kube-policy-controller:v0.7.0           env:             - name: ETCD_ENDPOINTS               value: "http://192.168.56.110:2379"             - name: K8S_API               value: "https://kubernetes.default:443"             - name: CONFIGURE_ETC_HOSTS               value: "true"
