Automatic deployment of Powershell

Automatic deployment of Powershell
Zookeeper

The repetitive version migration at work has been launched more than 10 times a day, which makes me uncomfortable. Frequent operations may also lead to fatigue errors, resulting in serious production faults. In my spare time, I started to study how to use powershell to automatically deploy programs on Linux servers.

The script involves the following tools:

1. Wincp: use its own command line mode to deploy the program

2. the ssh-session module of powershell connects to the Linux server by loading the module and runs the shell command.

3.. net

Start code
