以下机器为虚拟机

机器IP 主机名角色系统版本备注 172.16.94.140 kube-master-0 k8s master Centos 4.17.14 内存：3G 172.16.94.141 kube-node-41 k8s node Centos 4.17.14 内存：3G 172.16.94.142 kube-node-42 k8s node Centos 4.17.14 内存：3G 172.16.94.135 部署管理机 - 1.2. 配置管理机

管理机主要用来部署k8s集群，需要安装以下版本的软件，具体可参考：

https://github.com/kubernetes-incubator/kubespray#requirements

https://github.com/kubernetes-incubator/kubespray/blob/master/requirements.txt

ansible>=2.4.0 jinja2>=2.9.6 netaddr pbr>=1.6 ansible-modules-hashivault>=3.9.4 hvac

1、安装及配置ansible

参考ansible的使用。给部署机器配置SSH的免密登录权限，具体参考ssh免密登录。

2、安装python-netaddr

# 安装pip yum -y install epel-release yum -y install python-pip # 安装python-netaddr pip install netaddr

3、升级Jinja

# Jinja 2.9 (or newer) pip install --upgrade jinja2 1.3. 配置部署机器

部署机器即用来运行k8s集群的机器，包括Master和Node。

1、确认系统版本

本文采用centos7的系统，建议将系统内核升级到4.x.x以上。

2、关闭防火墙

systemctl stop firewalld systemctl disable firewalld iptables -F

3、关闭swap

Kubespary v2.5.0的版本需要关闭swap，具体参考

https://github.com/kubernetes-incubator/kubespray/blob/02cd5418c22d51e40261775908d55bc562206023/roles/kubernetes/preinstall/tasks/verify-settings.yml#L75 - name: Stop if swap enabled assert: that: ansible_swaptotal_mb == 0 when: kubelet_fail_swap_on|default(true) ignore_errors: "{{ ignore_assert_errors }}"

V2.6.0 版本去除了swap的检查，具体参考：

https://github.com/kubernetes-incubator/kubespray/commit/b902602d161f8c147f3d155d2ac5360244577127#diff-b92ae64dd18d34a96fbeb7f7e48a6a9b

执行关闭swap命令swapoff -a。

[root@master ~]#swapoff -a [root@master ~]# [root@master ~]# free -m total used free shared buff/cache available Mem: 976 366 135 6 474 393 Swap: 0 0 0 # swap 一栏为0，表示已经关闭了swap

4、确认部署机器内存

由于本文采用虚拟机部署，内存可能存在不足的问题，因此将虚拟机内存调整为3G或以上；如果是物理机一般不会有内存不足的问题。具体参考：

https://github.com/kubernetes-incubator/kubespray/blob/95f1e4634a1c50fa77312d058a2b713353f4307e/roles/kubernetes/preinstall/tasks/verify-settings.yml#L52 - name: Stop if memory is too small for masters assert: that: ansible_memtotal_mb >= 1500 ignore_errors: "{{ ignore_assert_errors }}" when: inventory_hostname in groups['kube-master'] - name: Stop if memory is too small for nodes assert: that: ansible_memtotal_mb >= 1024 ignore_errors: "{{ ignore_assert_errors }}" when: inventory_hostname in groups['kube-node'] 1.4. 涉及镜像

Docker版本为17.03.2-ce。

3、说明

镜像被墙并且全部镜像下载需要较多时间，建议提前下载到部署机器上。 hyperkube镜像主要用来运行k8s核心组件（例如kube-apiserver等）。此处使用的网络组件为calico。 2. 部署集群 2.1. 下载kubespary的源码 git clone https://github.com/kubernetes-incubator/kubespray.git 2.2. 编辑配置文件 2.2.1. hosts.ini

hosts.ini主要为部署节点机器信息的文件，路径为：kubespray/inventory/sample/hosts.ini。

cd kubespray # 复制一份配置进行修改 cp -rfp inventory/sample inventory/k8s vi inventory/k8s/hosts.ini

例如：

hosts.ini文件可以填写部署机器的登录密码，也可以不填密码而设置ssh的免密登录。

k8s-cluster.yml主要为k8s集群的配置文件，路径为：kubespray/inventory/k8s/group_vars/k8s-cluster.yml。该文件可以修改安装的k8s集群的版本，参数为：kube_version: v1.9.5。具体可参考：

https://github.com/kubernetes-incubator/kubespray/blob/master/inventory/sample/group_vars/k8s-cluster.yml#L22 2.3. 执行部署操作

涉及文件为cluster.yml。

# 进入主目录 cd kubespray # 执行部署命令 ansible-playbook -i inventory/k8s/hosts.ini cluster.yml -b -vvv

-vvv 参数表示输出运行日志

如果需要重置可以执行以下命令：

涉及文件为reset.yml。

ansible-playbook -i inventory/k8s/hosts.ini reset.yml -b -vvv 3. 确认部署结果 3.1. ansible的部署结果

ansible命令执行完，出现以下日志，则说明部署成功，否则根据报错内容进行修改。

2、k8s节点信息

# kubectl get nodes NAME STATUS ROLES AGE VERSION kube-master-0 Ready master 22h v1.9.5 kube-node-41 Ready node 22h v1.9.5 kube-node-42 Ready node 22h v1.9.5

3、组件健康信息

# kubectl get cs NAME STATUS MESSAGE ERROR scheduler Healthy ok controller-manager Healthy ok etcd-0 Healthy {"health": "true"} 4. k8s集群扩容节点 4.1. 修改hosts.ini文件

如果需要扩容Node节点，则修改hosts.ini文件，增加新增的机器信息。例如，要增加节点机器kube-node-43（IP为172.16.94.143），修改后的文件内容如下：

# Configure 'ip' variable to bind kubernetes services on a # different ip than the default iface # 主机名 ssh登陆IP ssh用户名 ssh登陆密码机器IP 子网掩码 kube-master-0 ansible_ssh_host=172.16.94.140 ansible_ssh_user=root ansible_ssh_pass=123 ip=172.16.94.140 mask=/24 kube-node-41 ansible_ssh_host=172.16.94.141 ansible_ssh_user=root ansible_ssh_pass=123 ip=172.16.94.141 mask=/24 kube-node-42 ansible_ssh_host=172.16.94.142 ansible_ssh_user=root ansible_ssh_pass=123 ip=172.16.94.142 mask=/24 kube-node-43 ansible_ssh_host=172.16.94.143 ansible_ssh_user=root ansible_ssh_pass=123 ip=172.16.94.143 mask=/24 # configure a bastion host if your nodes are not directly reachable # bastion ansible_ssh_host=x.x.x.x [kube-master] kube-master-0 [etcd] kube-master-0 [kube-node] kube-node-41 kube-node-42 kube-node-43 [k8s-cluster:children] kube-node kube-master [calico-rr] 4.2. 执行扩容命令

涉及文件为scale.yml。

# 进入主目录 cd kubespray # 执行部署命令 ansible-playbook -i inventory/k8s/hosts.ini scale.yml -b -vvv 4.3. 检查扩容结果

1、ansible的执行结果

PLAY RECAP *************************************** kube-node-41 : ok=228 changed=11 unreachable=0 failed=0 kube-node-42 : ok=197 changed=6 unreachable=0 failed=0 kube-node-43 : ok=227 changed=69 unreachable=0 failed=0 # 新增Node节点 localhost : ok=2 changed=0 unreachable=0 failed=0

2、k8s的节点信息

# kubectl get nodes NAME STATUS ROLES AGE VERSION kube-master-0 Ready master 1d v1.9.5 kube-node-41 Ready node 1d v1.9.5 kube-node-42 Ready node 1d v1.9.5 kube-node-43 Ready node 1m v1.9.5 #该节点为新增Node节点

可以看到新增的kube-node-43节点已经扩容完成。

3、k8s组件信息

# kubectl get po --namespace=kube-system -o wide NAME READY STATUS RESTARTS AGE IP NODE calico-node-22vsg 1/1 Running 0 10h 172.16.94.140 kube-master-0 calico-node-8fz9x 1/1 Running 2 27m 172.16.94.143 kube-node-43 calico-node-t7zgw 1/1 Running 0 10h 172.16.94.142 kube-node-42 calico-node-zqnx8 1/1 Running 0 10h 172.16.94.141 kube-node-41 kube-apiserver-kube-master-0 1/1 Running 0 1d 172.16.94.140 kube-master-0 kube-controller-manager-kube-master-0 1/1 Running 0 10h 172.16.94.140 kube-master-0 kube-dns-79d99cdcd5-f2t6t 3/3 Running 0 10h 10.233.100.194 kube-node-41 kube-dns-79d99cdcd5-gw944 3/3 Running 0 10h 10.233.107.1 kube-node-42 kube-proxy-kube-master-0 1/1 Running 2 1d 172.16.94.140 kube-master-0 kube-proxy-kube-node-41 1/1 Running 3 1d 172.16.94.141 kube-node-41 kube-proxy-kube-node-42 1/1 Running 3 1d 172.16.94.142 kube-node-42 kube-proxy-kube-node-43 1/1 Running 0 26m 172.16.94.143 kube-node-43 kube-scheduler-kube-master-0 1/1 Running 0 10h 172.16.94.140 kube-master-0 kubedns-autoscaler-5564b5585f-lt9bb 1/1 Running 0 10h 10.233.100.193 kube-node-41 kubernetes-dashboard-69cb58d748-wmb9x 1/1 Running 0 10h 10.233.107.2 kube-node-42 nginx-proxy-kube-node-41 1/1 Running 3 1d 172.16.94.141 kube-node-41 nginx-proxy-kube-node-42 1/1 Running 3 1d 172.16.94.142 kube-node-42 nginx-proxy-kube-node-43 1/1 Running 0 26m 172.16.94.143 kube-node-43 5. 部署高可用集群

将hosts.ini文件中的master和etcd的机器增加到多台，执行部署命令。

ansible-playbook -i inventory/k8s/hosts.ini cluster.yml -b -vvv

例如：

# Configure 'ip' variable to bind kubernetes services on a # different ip than the default iface # 主机名 ssh登陆IP ssh用户名 ssh登陆密码机器IP 子网掩码 kube-master-0 ansible_ssh_host=172.16.94.140 ansible_ssh_user=root ansible_ssh_pass=123 ip=172.16.94.140 mask=/24 kube-master-1 ansible_ssh_host=172.16.94.144 ansible_ssh_user=root ansible_ssh_pass=123 ip=172.16.94.144 mask=/24 kube-master-2 ansible_ssh_host=172.16.94.145 ansible_ssh_user=root ansible_ssh_pass=123 ip=172.16.94.145 mask=/24 kube-node-41 ansible_ssh_host=172.16.94.141 ansible_ssh_user=root ansible_ssh_pass=123 ip=172.16.94.141 mask=/24 kube-node-42 ansible_ssh_host=172.16.94.142 ansible_ssh_user=root ansible_ssh_pass=123 ip=172.16.94.142 mask=/24 kube-node-43 ansible_ssh_host=172.16.94.143 ansible_ssh_user=root ansible_ssh_pass=123 ip=172.16.94.143 mask=/24 # configure a bastion host if your nodes are not directly reachable # bastion ansible_ssh_host=x.x.x.x [kube-master] kube-master-0 kube-master-1 kube-master-2 [etcd] kube-master-0 kube-master-1 kube-master-2 [kube-node] kube-node-41 kube-node-42 kube-node-43 [k8s-cluster:children] kube-node kube-master [calico-rr] 6. 升级k8s集群

选择对应的k8s版本信息，执行升级命令。涉及文件为upgrade-cluster.yml。

ansible-playbook upgrade-cluster.yml -b -i inventory/k8s/hosts.ini -e kube_version=v1.10.4 -vvv 7. troubles shooting

在使用kubespary部署k8s集群时，主要遇到以下报错。

7.1. python-netaddr未安装报错内容： fatal: [node1]: FAILED! => {"failed": true, "msg": "The ipaddr filter requires python-netaddr be installed on the ansible controller"} 解决方法：

需要安装 python-netaddr，具体参考上述[环境准备]内容。

7.2. swap未关闭报错内容： fatal: [kube-master-0]: FAILED! => { "assertion": "ansible_swaptotal_mb == 0", "changed": false, "evaluated_to": false } fatal: [kube-node-41]: FAILED! => { "assertion": "ansible_swaptotal_mb == 0", "changed": false, "evaluated_to": false } fatal: [kube-node-42]: FAILED! => { "assertion": "ansible_swaptotal_mb == 0", "changed": false, "evaluated_to": false } 解决方法：

所有部署机器执行swapoff -a关闭swap，具体参考上述[环境准备]内容。

7.3. 部署机器内存过小报错内容： TASK [kubernetes/preinstall : Stop if memory is too small for masters] ********************************************************************************************************************************************************************************************************* task path: /root/gopath/src/kubespray/roles/kubernetes/preinstall/tasks/verify-settings.yml:52 Friday 10 August 2018 21:50:26 +0800 (0:00:00.940) 0:01:14.088 ********* fatal: [kube-master-0]: FAILED! => { "assertion": "ansible_memtotal_mb >= 1500", "changed": false, "evaluated_to": false } TASK [kubernetes/preinstall : Stop if memory is too small for nodes] *********************************************************************************************************************************************************************************************************** task path: /root/gopath/src/kubespray/roles/kubernetes/preinstall/tasks/verify-settings.yml:58 Friday 10 August 2018 21:50:27 +0800 (0:00:00.570) 0:01:14.659 ********* fatal: [kube-node-41]: FAILED! => { "assertion": "ansible_memtotal_mb >= 1024", "changed": false, "evaluated_to": false } fatal: [kube-node-42]: FAILED! => { "assertion": "ansible_memtotal_mb >= 1024", "changed": false, "evaluated_to": false } to retry, use: --limit @/root/gopath/src/kubespray/cluster.retry 解决方法：

调大所有部署机器的内存，本示例中调整为3G或以上。

7.4. kube-scheduler组件运行失败

kube-scheduler组件运行失败，导致http://localhost:10251/healthz调用失败。

报错内容： FAILED - RETRYING: Master | wait for kube-scheduler (1 retries left). FAILED - RETRYING: Master | wait for kube-scheduler (1 retries left). fatal: [node1]: FAILED! => {"attempts": 60, "changed": false, "content": "", "failed": true, "msg": "Status code was not [200]: Request failed: ", "redirected": false, "status": -1, "url": "http://localhost:10251/healthz"} 解决方法：

可能是内存不足导致，本示例中调大了部署机器的内存。

7.5. docker安装包冲突报错内容： failed: [k8s-node-1] (item={u'name': u'docker-engine-1.13.1-1.el7.centos'}) => { "attempts": 4, "changed": false, ...
