Kubernetes-1.12.3-all-auto-install

Project Introduction

Personally organized Centos7.x + Kubernetes-1.12.3 + Dashboard-1.8.3 automatic one-click installation and deployment files for master and node nodes without CVE-2018-1002105 vulnerability, suitable for quick deployment in test and production environments.

Master Node Installation Preparation

1. Configure the CentOS network environment to connect to the internet for downloading installation files.
2. Log in to CentOS 7 as root, and copy all *.sh and *.ymal files from this project to the /root/ directory.
3. Modify file permissions for *.sh:

chmod +777 /root/*.sh

4. Execute the following command to replace the IP in *.sh with your CentOS 7 IP address.

# 修改替换下面的your_master_centos_ip为你的master_centos的ip
sed -i "s/192.168.119.212/your_master_centos_ip/g" /root/*.sh

Master Node Installation Guide

1. Run node-kubeadm-init.sh to install the Kubernetes 1.12.3 environment.

sh /root/node-kubeadm-init.sh

2. Run node-kubeadm-install.sh to install the Kubernetes Dashboard 1.8.3 management UI.

sh /root/node-kubeadm-install.sh

3. After completion, open a browser and visit: https://your_centos_ip:30001. Log in using a token. How to view the token:

#执行命令，获取所有密钥列表：
kubectl -n kube-system get secret
#执行命令，获取指定key的token:
kubectl -n kube-system describe secret kubernetes-dashboard-admin-token-* #{上条命令输出的结果中复制的类似kubernetes-dashboard-admin-token-skhfh的key字符串到这里替换}
#复制tokdn数据到登录框内登录即可登录

--- At this point, the single-node Kubernetes installation is complete. To add a new node, see below.

Node Joining Preparation

1. Configure the CentOS network environment to connect to the internet for downloading installation files.
2. Log in to CentOS 7 as root, and copy the node_kubeadm_join.sh file from this project to the /root/ directory.
3. Modify file permissions for *.sh:

chmod +777 /root/*.sh

4. Execute the following command to replace the IP in *.sh with your CentOS 7 IP address.

# 修改替换下面的your_master_centos_ip为你的master_centos的ip
sed -i "s/192.168.119.212/your_master_centos_ip/g" /root/*.sh
# 修改替换下面的your_node_centos_ip为你的node_centos的ip
sed -i "s/192.168.168.145/your_node_centos_ip/g" /root/*.sh
# 修改替换下面的your_node_centos_host为你的node_centos的host,格式如：node-192-168-168-145,用ip值，将.替换为-
sed -i "s/node-192-168-168-145/your_node_centos_host/g" /root/*.sh
# 修改替换下面的your_join_token为master的加入token
# 查看master加入token方法：在master节点执行：kubectl token list,获取未过期的token
# 在master新建token方法：在master节点执行：kubectl create token
sed -i "s/join_token/your_join_token/g" /root/*.sh

Node Joining Guide

1. Run node-kubeadm-join.sh to add a new node.

sh /root/node-kubeadm-join.sh

3. After completion, open a browser and visit: https://your_master_centos_ip:30001 to check the node readiness status. Node preparation takes a while.
