- Understand ansible architecture and working principles
- Ansible is a model-driven configuration manager that supports multi-node publishing and remote task execution. By default, SSH is used for remote connections. There is no need to install additional software on managed nodes and it can be extended using a variety of programming languages. 1. Ansible Basic Architecture The picture above shows the basic structure of ansible. From the picture above, you can understand that it consists of the following parts: Core: ansible core modules (CoreModules): These are the modules that come with ansible. Extension modules (CustomModules): If the core If the module is not enough to complete a certain function, you can add extension module plug-ins (Plugins): Supplementary playbooks (Playbooks) to complete the module function: a

- Humanized HTTP command line tool——HTTPie
- This article is mainly to let readers understand Httpie, the HTTP command line client, and also learn about the interface. What is Httpie? Httpie (aych-tee-tee-pie) is an HTTP command line client. The goal is to make the interaction between the CLI and web services as user-friendly as possible. You can use it to easily debug the interface using http commands. The most commonly used ones are GET and POST. What is an interface? To give a simple example, if there is a pet store that sells animal food, such as cat food and dog food, then the food sold is an interface. If the cat comes, it will sell cat food, and if the dog comes, it will sell dog food. What kind of chicken, duck, fish or something like that? Just modify this

The exit status of the previous command, or the return value of the function. Returns 0 on success, 1 on failure $#Number of parameters passed to the script or function $* All these parameters are enclosed in double quotes. If a script receives two parameters, $* is equal to $1$2$0The name of the command being executed. For shell scripts, this is the path to the activated command. When $@ is enclosed in double quotes (""), it is slightly different from $*. If a script receives two parameters, $@ is equivalent to $1$2$$the process number of the current shell.

- How to use Golang logs to monitor your application?
- But how do you use Golang logs to monitor your application? There are no exceptions in Golang, only errors. So your first impression may be that developing a Golang logging strategy is not a simple matter. Not supporting exceptions is actually not a problem, exceptions have lost their exceptionality in many programming languages: they are so overused that their usefulness is ignored. Before going further, we will first introduce the basics of Golang logging and discuss Golang logging standards, the meaning of metadata, and minimizing the impact of Golang logging on performance. With logs, you can track user activity in your app, quickly identify broken components in your project, and monitor overall performance and user experience.

- Introduction to the classic and easy-to-use JavaScript framework Vue.js
- This article aims to introduce a useful JavaScript framework Vue.js, so that readers can have a preliminary understanding of it. What is VueVue (pronounced /vjuː/, similar to view) is a progressive framework for building user interfaces. Unlike other large frameworks, Vue is designed to be applied layer by layer from the bottom up. Vue's core library only focuses on the view layer, which is not only easy to get started, but also easy to integrate with third-party libraries or existing projects. On the other hand, when combined with a modern tool chain and various supporting libraries, Vue is fully capable of providing drivers for complex single-page applications. Features of Vue - Computed properties It is very convenient to write expressions in Vue templates, but if you put complex

- Ansible usage: simple use of ansible-playbook
- ansbile-playbook is a collection of system ansible commands, which are written in the yaml language and run during the process. The ansbile-playbook commands are executed in a top-down order. At the same time, playbook has created many features. It allows you to transfer the status of a certain command to a subsequent command. For example, you can grab content from a file on one machine and attach it as a variable, and then use it on another machine. This allows you to implement some complex deployment mechanisms that are not possible with ansible commands. playbook is used through the ansible-playbook command. Its parameters are similar to the ansible command, such as the parameter -k(–as

- Introducing ansible's Ad-hoc and commands modules
- Ad-Hoc refers to a command that is temporarily executed under ansible and does not need to be saved. For complex commands, playbook will be mentioned later. When talking about Ad-hoc, we must mention modules. All command execution depends on pre-written modules. Ansible installed by default already comes with many modules, such as: command, raw, shell, file, cron, etc. , which can be viewed through ansible-doc-l. 1. Ad-hoc1. Direct execution.
