puppet vs docker

Anchor Background: puppet Forge is an online module repository. Many puppet modules are uploaded for download. You can download a module and use it directly. You should not change the manifests in it. However, in puppet2.6, when a class declares another class, the declared class resources will not be included by the external class, this makes it impossible for us to form a module with complex functions thro

Requirements: Dev groups are created on each server, dedicated to developers, build accounts for specific developers, and join Dev Group; Operators will also create their own users, and join the wheel group, through Sudo to the group members do permission settings. The architecture is as follows: The contents of the documents in Manfests are as follows: 1,init.pp class Sudo {case $::osfamily {' RedHat ': {include ' sudo::conf ' ' import ' sudo Ers.pp '} default: {Fail ("$::osfamil

The first thing that comes to mind is greed... Definitely not... T Then we found that it was actually DP-enabled... However, we need to sort them first. If f [I] indicates that the first puppet has to lose a few at worst F [I] = max (F [J] + calc (J + 1, I) where j The calc (x, y) function compute can discard a maximum of several matching functions from the X to the Y puppet. The method is as follows: Hzw

This article for the translation of foreign tutorials, teach you to use Photoshop to create surreal cosmic science fiction puppet beauty effect, the production process is not difficult, mainly in your imagination and creativity, like the students can learn! Let's take a look at the final results of the Photoshop Tutorial: 1. Create a new file, size set to 4200px x 5100px pixels, resolution 300, fill black. Search the web for the nebula footag

Teach us to use PS synthesis to build wiring puppet robot small s effect, the tutorial is relatively simple, mainly through the pen tool, selection, layer style, etc. to complete, like the students can come together to learn!

The Agent/master HTTP interface is rest-like and varies from strictly RESTful design in several ways. The endpoints used by the agent is detailed in the HTTP API reference. Note that all HTTP endpoints is preceded by the environment being used. Note also that access to each individual endpoint are controlled byauth.conf on the master.DiagramThis flow diagram illustrates the pattern of agent-side checks and HTTPS requests to the puppet master during a

,onlineuser); Where Login_no is the variable is the login name. To set the Request.getsession (false) value to False, he has a value of true and false two, true if it is created if there is no same session. If there is coverage, false is not created, then not created, I want to use this to achieve a single sign-on so use false. This will allow you to monitor the session you created. If the session times out, the Valueunbound method is executed. Creating a session executes the Valuebound method.

Docker-2 learn more about docker, docker-2dockerDockerBasic concepts of images, containers, and warehousesImages A Docker image is a read-only template.For example, an image can contain a complete CentOS operating system environment where only httpd or other applications are installed. Images can be used to create

. For example, if you want to modify a file, the file is copied from the read-only layer below the read-write layer to the read-write layer. The read-only version of the file still exists, but it has been hidden by a copy of the file in the read-write layer. This mechanism is copied as a write-time.Docker Images #查看所有的docker镜像The local image is saved under/var/lib/docker, and all the containers are stored i
