k8s-deploy:使用Ansible部署Kubernetes
可以使用Ansible来安装Kubernetes集群。首先,您需要编写一个Ansible playbook,其中包含安装Kubernetes所需的所有步骤。然后,您可以使用Ansible命令来运行该playbook,以自动化整个安装过程。以下是一个简单的Ansible playbook示例:
```
- hosts: kubernetes
become: true
tasks:
- name: Install Docker
apt:
name: docker.io
state: present
- name: Add Kubernetes apt key
apt_key:
url: https://packages.cloud.google.com/apt/doc/apt-key.gpg
state: present
- name: Add Kubernetes apt repository
apt_repository:
repo: deb http://apt.kubernetes.io/ kubernetes-xenial main
state: present
- name: Install Kubernetes components
apt:
name: "{{ item }}"
state: present
with_items:
- kubelet
- kubeadm
- kubectl
- name: Initialize Kubernetes cluster
command: kubeadm init --pod-network-cidr=10.244.0.0/16
- name: Copy Kubernetes config file
command: mkdir -p $HOME/.kube && cp /etc/kubernetes/admin.conf $HOME/.kube/config
- name: Install Flannel network plugin
command: kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
```
该playbook将在名为“kubernetes”的主机组中安装Docker和Kubernetes组件,并使用Flannel网络插件初始化Kubernetes集群。您可以使用以下命令来运行该playbook:
```
ansible-playbook -i inventory.ini kubernetes.yml
```
其中,“inventory.ini”是包含主机列表的Ansible inventory文件,“kubernetes.yml”是您编写的playbook文件。
