ansible playbook初始化系统基础环境，直接就可以用
ins
#on master pip3 install --user ansible ssh-copy-id -i id_ecdsa.pub [email protected] ssh-copy-id -i id_ecdsa.pub [email protected] ssh-copy-id -i id_ecdsa.pub [email protected] mkdir /etc/ansible vi /etc/ansible/hosts 192.168.88.50 192.168.88.51 192.168.88.52 [intra] 192.168.10.120 192.168.10.121 ansible all -b -u root -a "hostname" 192.168.88.51 | CHANGED | rc=0 >> k8s-node1 192.168.88.50 | CHANGED | rc=0 >> k8s-master 192.168.88.52 | CHANGED | rc=0 >> k8s-node2 ansible all -m ping
配置文件
ansible在使用配置文件时按照以下顺序优先配置： export ANSIBLE_CONFIG ./ansible.cfg ~/.ansible.cfg /etc/ansible/ansible.cfg 如果以上顺序没有找到配置文件ansible会自动使用默认配置 可以去github上把默认配置拿下来： https://raw.githubusercontent.com/ansible/ansible/devel/examples/ansible.cfg # To generate an example config file (a "disabled" one with all default settings, commented out): # $ ansible-config init --disabled > ansible.cfg # Also you can now have a more complete file by including existing plugins: # ansible-config init --disabled -t all > ansible.cfg 把它放到/etc/ansible/目录
