puppet dsl

Storm provides a set of clojure DSL to define spouts, bolts, and topologies. Since clojure DSL can call all exposed Java APIsClojure developers can write storm topologys without having to access Java code. The code that defines clojure DSL is in the namespace of backtype. Storm. clojure.This section describes how to use clojure

In the first two sections, we have completed metadata creation and partial graphical representation of the state machine. If you have used a running state machine designer, you will find many problems. in this section, we mainly improve our state machine instances, including metadata and graphical symbols.Complete1. in the running environment, you will find that the selected item text displayed in the left-side toolbox is still automatically generated lanaguesm, and we need to change it to state

Originally in Ubuntu 15.10 with dial-up Internet no problem, but upgraded 16.04 LTS found the original DSL connection is not on. The main performance is:1, in NetworkManager the choice DSL connection can try to dial the connection, even after two or three seconds on the broken;2, after many times in accordance with the online method to modify the strange configuration, ultimately not even at all;3, delete t

Recently, there has been a resurgence of interest in DSL prototyping in domain-specific language F #. These languages can not only provide a better level of refinement for specific areas, thus helping to reduce errors caused by low-level constructs in common languages, but they provide an effective mechanism for users to tune your applications by providing additional configuration, custom business logic, and so on. In short, DSLs can make your applica

The puppet Update method based on C/s architecture generally has two kinds, one is the agent side set synchronization time active to puppet Master end pull configuration, the other is through the puppet master side use Puppet Kick command or trigger update configuration with mcollctive. 1.

I. Introduction of PuppetPuppet is a configuration management software designed for data Center Automation management that manages the entire lifecycle of your IT Infrastructure: provisioning (provisioning) provisioning (configuration), Linkage (orchestration) and reporting (reporting). Puppet is based on the C/s architecture, similar to Zabbiz, with the master and Agent node points. It is an open source (not really open source, because of the commerc

Introduction: So far, evolution architecture and emergency design focus on the emergency design of the technical model, this period will introduce the use of specific domain language (DSL) capture domain idiomatic patterns. The series author Neal Ford illustrated the method with an example that shows the advantage of this abstract style of acquiring idiomatic patterns. Idiomatic patterns can be either technology or domain. The technology model identi

Vsts and DSL have been talking for a long time. Now it's almost time to try to pull... one of the main reasons why I didn't try it is because I used Java for a long time. Today, I downloaded related installation programs and some tutorials. If you are interested, you can try to reuse the results of Google.

How to Use Puppet and Augeas to manage Linux configurations Although Puppet is a truly unique and useful tool, you can use it in some cases in a different way. For example, you need to modify several existing configuration files on the server, and they are slightly different from each other. People at the Puppet Lab also realized this. They integrated a great too
