calico网络
环境
系统 centos 7.2
ip 10.0.0.51
IP 10.0.0.61
1.下载etcd
wget https://github.com/coreos/etcd/releases/download/v3.0.4/etcd-v3.0.4-linux-amd64.tar.gz
tar xf etcd-v3.0.4-linux-amd64.tar.gz
cd etcd-v3.0.4-linux-amd64
cp etcd /usr/bin/etcd && cp etcdctl /usr/bin/etcdctl
2.链接etcd集群
calico1执行
etcd --name infra0 --initial-advertise-peer-urls http://10.0.0.51:2380 --listen-peer-urls http://10.0.0.51:2380 --listen-client-urls http://10.0.0.51:2379,http://127.0.0.1:2379 --advertise-client-urls http://10.0.0.51:2379 --initial-cluster-token etcd-cluster-1 --initial-cluster infra0=http://10.0.0.51:2380,infra1=http://10.0.0.61:2380 --initial-cluster-state new &
calico2执行
etcd --name infra0 --initial-advertise-peer-urls http://10.0.0.61:2380 --listen-peer-urls http://10.0.0.61:2380 --listen-client-urls http://10.0.0.61:2379,http://127.0.0.1:2379 --advertise-client-urls http://10.0.0.61:2379 --initial-cluster-token etcd-cluster-1 --initial-cluster infra0=http://10.0.0.61:2380,infra1=http://10.0.0.51:2380 --initial-cluster-state new &
3.查看
etcdctl member list
docker配置
1.下载doker
yum install -y docker
2.修改docker的配置文件
calico1修改
vim /usr/lib/systemd/system/docker.service
ExecStart=/usr/bin/dockerd $INSECURE_REGISTRY --cluster-store=etcd://10.0.0.51:2379
calico2修改
vim /usr/lib/systemd/system/docker.service
3.启动docker
systemctl daemon-reload
systemctl restart docker
三.calico
需要先下载calico/node 镜像
1.下载calico并授权
wget http://www.projectcalico.org/latest/calicoctl
chmod +x calicoctl && mv calicoctl /usr/local/bin
2.执行calico命令
1.在本机执行
calicoctl node run
2.在另一台执行
ETCD_ENDPOINTS=http://10.0.0.51:2379 calicoctl node run
3.查看
calicoctl node status
4.创建网络池
cat > calico_pool_minion5.conf <<EOF
apiVersion: v1kind: ipPoolmetadata: cidr: 10.1.0.0/16spec: ipip: enabled: false nat-outgoing: true disabled: falseEOF docker network create -d calico --ipam-driver calico-ipam --subnet=10.1.0.0/16 net1
docker network ls
7.测试
