k8s-deploy:使用Ansible部署Kubernetes
下面是一段使用Ansible部署Kubernetes的代码示例:
```
---
- name: Deploy Kubernetes Cluster
hosts: k8s-master
become: yes
vars:
k8s_version: 1.21.0
calico_version: 3.16.6
etcd_version: 3.4.13
tasks:
- name: Install Docker
package:
name: docker-ce
state: present
- name: Install Ansible
package:
name: ansible
state: present
- name: Install kubeadm, kubelet, and kubectl
shell: |
apt-get update && apt-get install -y apt-transport-https curl
curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | apt-key add -
echo "deb https://apt.kubernetes.io/ kubernetes-xenial main" | tee -a /etc/apt/sources.list.d/kubernetes.list
apt-get update
apt-get install -y kubeadm={{ k8s_version }}-00 kubelet={{ k8s_version }}-00 kubectl={{ k8s_version }}-00
- name: Initialize kubeadm
shell: kubeadm init --pod-network-cidr=192.168.0.0/16
- name: Setup kubectl config
shell: |
mkdir -p $HOME/.kube
cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
chown $(id -u):$(id -g) $HOME/.kube/config
- name: Deploy Calico network plugin
shell: |
kubectl apply -f https://docs.projectcalico.org/{{ calico_version }}/manifests/calico.yaml
- name: Check the cluster status
shell: kubectl get nodes
```
该代码段实现了以下功能:
1. 安装Docker和Ansible
2. 安装Kubernetes的kubeadm, kubelet和kubectl
3. 使用kubeadm进行初始化
4. 设置kubectl的配置文件
5. 部署Calico网络插件
6. 检查集群状态。
请注意,这仅是一个示例代码,可能需要根据实际情况进行修改。
