ansible-playbook部署K8S集群
本文主要是介绍ansible-playbook部署K8S集群，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！
通过ansible-playbook，以Kubeadm方式部署K8S集群（一主多从）。
kubernetes安装目录： /etc/kubernetes/ KubeConfig： ~/.kube/config Version： v1.18.3
主机说明：
| 系统 | ip | 角色 | cpu | 内存 | hostname |
|---|---|---|---|---|---|
| CentOS 7.8 | 192.168.30.128 | master | >=2 | >=2G | master |
| CentOS 7.8 | 192.168.30.129 | node | >=2 | >=2G | node1 |
| CentOS 7.8 | 192.168.30.130 | node | >=2 | >=2G | node2 |
| CentOS 7.8 | 192.168.30.131 | node | >=2 | >=2G | node3 |
准备
- 将所有部署k8s集群的主机分组：
# vim /etc/ansible/hosts[master]192.168.30.128 hostname=master[node]192.168.30.129 hostname=node1 192.168.30.130 hostname=node2 192.168.30.131 hostname=node3
- 创建管理目录：
mkdir -p k8s/roles/{docker_install,master_install,node_install,addons_install}/{files,handlers,meta,tasks,templates,vars}cd k8s/说明：
files：存放需要同步到异地服务器的源码文件及配置文件； handlers：当资源发生变化时需要进行的操作，若没有此目录可以不建或为空； meta：存放说明信息、说明角色依赖等信息，可留空； tasks：K8S 安装过程中需要进行执行的任务； templates：用于执行 K8S 安装的模板文件，一般为脚本； vars：本次安装定义的变量
tree ..├── k8s.yml └── roles ├── addons_install │ ├── files │ ├── handlers │ ├── meta │ ├── tasks │ │ ├── calico.yml │ │ ├── ingress.yml │ │ └── main.yml │ ├── templates │ │ ├── calico-rbac.yaml │ │ ├── calico.yaml │ │ └── ingress-nginx.yaml │ └── vars │ └── main.yml ├── docker_install │ ├── files │ ├── handlers │ ├── meta │ ├── tasks │ │ ├── install.yml │ │ ├── main.yml │ │ └── prepare.yml │ ├── templates │ │ ├── daemon.json │ │ ├── install.sh │ │ ├── kubernetes.conf │ │ └── kubernetes.repo │ └── vars │ └── main.yml ├── master_install │ ├── files │ ├── handlers │ ├── meta │ ├── tasks │ │ ├── install.yml │ │ └── main.yml │ ├── templates │ │ └── kubeadm-config.yaml │ └── vars │ └── main.yml └── node_install ├── files ├── handlers ├── meta ├── tasks │ ├── install.yml │ └── main.yml ├── templates └── vars └── main.yml 29 directories, 23 files
- 创建安装入口文件，用来调用roles：
vim k8s.yml
---- hosts: all remote_user: root gather_facts: True roles: - docker_install- hosts: master remote_user: root gather_facts: True roles: - master_install- hosts: node remote_user: root gather_facts: True roles: - node_install - hosts: master remote_user: root gather_facts: True roles: - addons_install
docker部分
- 创建docker入口文件，用来调用docker_install：
vim docker.yml
- hosts: all remote_user: root gather_facts: True roles: - docker_install
- 创建变量：
vim roles/docker_install/vars/main.yml
SOURCE_DIR: /softwareVERSION: 1.18.3
- 创建模板文件：
docker配置daemon.json
vim roles/docker_install/templates/daemon.json

测试安装没有问题，注意kubernetes组件版本尽量一致。已存放至个人gitgub：ansible-playbook
