Using the shell module, the remote command is executed through/bin/sh, so we can use the various command methods in the terminal input;But we define our own environment variables in. Bashrc/.bash_profile The shell module is not recognized because it is not loaded, and if you need to use a custom environment variable, you need to execute the statement that loads the custom script at the very beginning;The use of shell modules can be divided into two bl

We then looked at how we can package up relatedincludes and automatically include them all at once using roles. Finally we discussedpull mode, which allows you to automate the deployment of playbooks on theremote node itself.In the next chapter, we will cover writing your own modules. We start this bybuilding a simple module using bash scri

The real batch deployment is the module that
