Difference between convergence and idempotence in Chef

阅读更多关于 Difference between convergence and idempotence in Chef

问题 What is the basic difference between convergence and idempotence in Chef? 回答1: Convergence and idempotence are not Chef-specific.

阅读更多关于 Chef libraries or definitions?

Basically the wordpress folder is on my host and gets mounted as shared folder in /var/www/wordpress in the VM. The configuration is similar to: config.vm.share_folder "foo", "/guest/path", "/host/path" My problem is that the ownership in my VM is always vagrant:vagrant even if I change it on my host. Ownership changes in the VM get ignored. I cannot use

Use of @ symbol in Node module names

阅读更多关于 Use of @ symbol in Node module names

问题 I\'m looking at some code from a coworker wrote and she\'s using the @ symbol in require statements. This is the first line of one of these files: var restServer = require(\'@company/config\') When I try to run this code, I get an error: Error: Cannot find module \'@company/config\' Which I frankly expect, there\'s nothing that looks like this in my directory for require to recognize!
