Kubernetes ADM Installation Tutorial (network using calico)

1. Disable Iptables

Each machine disables iptables to avoid iptables conflicts with Docker:

Systemctl Stop Firewalld

Systemctl Disable FIREWALLD

Disable SELinux:

Vim/etc/selinux/config

#SELINUX =enforcing

Selinux=disabled

2. Install Docker (master node) from overseas sources

Cat >/etc/yum.repos.d/docker.repo <<-eof

[Dockerrepo]

Name=docker Repository

baseurl=https://yum.dockerproject.org/repo/experimental/centos/7/

Enabled=1

Gpgcheck=1

Gpgkey=https://yum.dockerproject.org/gpg

Eof

Yum-y Install Docker-engine

Systemctl Enable Docker && Systemctl start Docker

3. Install k8s (master node) foreign source

Cat <<eof >/etc/yum.repos.d/kubernetes.repo

[Kubernetes]

Name=kubernetes

Baseurl=http://yum.kubernetes.io/repos/kubernetes-el7-x86_64

Enabled=1

Gpgcheck=1

Repo_gpgcheck=1

Gpgkey=https://packages.cloud.google.com/yum/doc/yum-key.gpg

Https://packages.cloud.google.com/yum/doc/rpm-package-key.gpg

Eof

Yum install-y kubelet kubeadm kubectl kubernetes-cni && systemctl enable Kubelet && systemctl start K Ubelet

4. Initialize Master

Kubeadm Init--token=b1f4c5.94d2933fea71f20b

Modify the configuration file/etc/kubernetes/manifests/

Etcd.json

--listen-client-urls=http://0.0.0.0:2379

--advertise-client-urls=http://172.22.0.4:2379 (native IP)

Kube-apiserver.json

--insecure-bind-address=0.0.0.0

5. Add node

Kubeadm Join--token b1f4c5.94d2933fea71f20b 172.22.0.4 (master IP)

Modifying a configuration file

/etc/systemd/system/kubelet.service.d/10-kubeadm.conf

At the back of Execstart=/usr/bin/kubelet this adds

--hostname-override=172.22.0.6 (node's own IP)

Systemctl daemon-reload && systemctl Restart Kubelet

6. Install calico (at master)

Download Http://docs.projectcalico.org/v1.5/getting-started/kubernetes/installation/hosted/kubeadm/calico.yaml

Modify Etcd_endpoints: "http://172.22.0.4:2379" (Master IP)

Delete about ETCD Daemonset Service Content

Kubectl create-f Calico.yaml

Testing is used by Ali to go abroad to the server, if the use of domestic has a mirror is pull down.
