Personal organized Centos7.x+Kubernetes-1.12.3+Dashboard-1.8.3 without CVE-2018-1002105 vulnerability master node fully automatic quick one-click installation deployment file, suitable for rapid installation and deployment of test environment and production environment

Preparation for installation of master node

Configure the network environment of centos to connect to the Internet and download installation files

Log in to centos7 with the root user and copy all the * .sh,*.ymal files in the project to the / root/ directory

Modify the file permissions of * .sh:

Chmod + 777 / root/*.sh

Execute the following command to replace ip in * .sh with the ip address of your centos7

# modify and replace the following your_master_centos_ip installation tutorial for your master_centos ipsed-I "s/192.168.119.212/your_master_centos_ip/g" / root/*.shmaster node

Execute node-kubeadm-init.sh to install kubernetes 1.12.3 environment

Sh / root/node-kubeadm-init.sh

Execute node-kubeadm-install.sh and install kubernetes-dashboard-1.8.3 Management UI

Sh / root/node-kubeadm-install.sh

When all is done, open the browser: visit: https://your_centos_ip:30001, log in using token, and view the token as follows:

# execute the command to get the list of all keys: kubectl-n kube-system get secret# execute command Get the token:kubectl-n kube-system describe secret kubernetes-dashboard-admin-token-* # {kubernetes-dashboard-admin-token-skhfh-like key string copied in the output of the previous command of the specified key and replace here} # copy the tokdn data into the login box to log in-- -- at this point, the Kubernetes installation of a single node is complete. If you want to add a new node, see below-node node join preparation

Configure the network environment of centos to connect to the Internet and download installation files

Log in to centos7 with the root user and copy the node_kubeadm_join.sh file in the project to the / root/ directory

Modify the file permissions of * .sh:

Chmod + 777 / root/*.sh

Execute the following command to replace ip in * .sh with the ip address of your centos7

# modify and replace the following your_master_centos_ip for your master_centos ipsed-I "s/192.168.119.212/your_master_centos_ip/g" / root/*.sh# modify replace the following your_node_centos_ip for your node_centos ipsed-I "s/192.168.168.145/your_node_centos_ip/g" / root/*.sh# modify and replace the following your_node _ centos_host is the host of your node_centos Format such as: node-192-168168-145with IP value Will. Replace by-sed-I "s/node-192-168168-145/your_node_centos_host/g" / root/*.sh# modify replace the following your_join_token for master join token# view master join token method: execute on master node: kubectl token list Get the unexpired token# to create a new token in master: execute the tutorial on the master node: kubectl create tokensed-I "s/join_token/your_join_token/g" / root/*.shnode node join the tutorial

Execute node-kubeadm-join.sh to join the new node

Sh / root/node-kubeadm-join.sh

When all is done, open the browser: visit: https://your_master_centos_ip:30001 to check the node preparation. It will take some time for the node to be ready.
