The difference between Webpack and Docker

The difference between Webpack and Docker

Webpack is a module packager. Its main function will be packaged according to the dependencies of the module to facilitate browsing. Docker is an open source application container engine that allows developers to package applications into containers and then publish them to any popular Linux machine.

Docker

The typical scenarios of docker are mentioned on the docker website:

• Automating the packaging and deployment of applications (automating the packaging and deployment of applications)

• Creation of lightweight, private PAAS environments (Creating lightweight, private PAAS environments)

• Automated testing and continuous integration/deployment

• Deploying and scaling web apps, databases and backend services（ Deploy and expand webapps, databases and background services)

Due to its lightweight virtualization characteristics based on LXC, the most obvious feature of docker compared to KVM and the like is that it starts quickly and resources Small footprint. Therefore, it is necessary to build an isolated and standardized operating environment, lightweight PaaS (such as dokku), build automated testing and continuous integration environments, and all applications that can be horizontally expanded (especially web applications that need to start and stop quickly to cope with peaks and valleys) .

To build a standardized operating environment, most of the existing solutions are to run a set of puppet/chef or an image file on a baseOS. The disadvantage is that the former requires many prerequisites of base OS, and the latter is almost impossible. Modify (because the file format of copy on write is read only when rootfs is running). Moreover, the latter file size is large, and environment management and version control itself are also a problem.

The PaaS environment is self-evident. At the beginning of its design and in the case of dotcloud, it was used as the environmental basis of PaaS products

because of its standardized construction method (buildfile) and good REST API, automated testing and continuous integration/deployment can be well integrated

Because of the lightweight characteristics of LXC, it starts quickly, and docker can only load the changed parts of each container, so that it takes up little resources , it can be faster and occupy less resources than virtualization solutions such as KVM in a stand-alone environment

Webpack

WebPack can be regarded as module packaging Machine: What it does is to analyze your project structure, find JavaScript modules and other extension languages ​​(Scss, TypeScript, etc.) that browsers cannot run directly, and convert and package them into a suitable format for browser use. .
