Lazy Evaluation In general, Ansible evaluates any variables in playbook content at the last possible second, which means that if you define a data structure that data structure itself can define variable values within it, and everything “just works” as you would expect. This also means va...
在官方文档中命令行的名字是:Ad-Hoc Commands ansible是指令核心部分,其主要用于执行ad-hoc命令,即单条命令。默认后面需要跟主机和选项部分,默认不指定模块时,使用的是command模块。如: [root@localhost ~]# ansible 127.0.0.1 -a 'date' -m:后面接调用模块的名字 -a:后面接调用模块的参数 ansible all -m she...

To avoid this situation, the service restart by the playbook can be disabled by using the vault_service_restart role variable. Setting this vault_service_restart to false will disable the vault service restart by the playbook. You may have to restart the service manually to load any new config...
