cloud foundry getting started

OverviewCloud Controller is responsible for managing the life cycle of the application. When a developer publishes an app to Cloud Foundry, it is published in cloud Controller, CC stores the original application section, creates a record to track the application's data, and informs the DEA to package and run the app. CC also holds information such as orgs, spaces

number of files and has a long time to operate, so it acts as a standalone process. Make the packaging work asynchronous. Does not clog the cloud Controller as a core component.Source Code GuideThe ability to find all of Cloudfoundry's code on GitHub: Https://github.com/cloudfoundry, you'll see several different repositories, each of which is:1, Vcap:cloud Foundry Core, or called kernel.2, Vcap-service:clo

The first version of the cloud controller was based on the Ruby on Rails, and the new cloud controller was rewritten with Sinatra, and part of the work was independentl

In cloud foundry V2, the platform uses warden technology to control and isolate resources for running user application instances. In a brief introduction, warden, that is, if dea_ng needs to run the user application instance (this article does not consider the staging packaging environment provided by Warden container), it will send the corresponding request to Warden server, the warden server creates ward

gateway and node are Nat messages. Note: the services provided by CF are deployed (or may not be started), and the service nodes are ready when CF is initialized. No software package is downloaded, installed, and deployed. Bind Service Bind a service to an application: Find the service instance, find the credentials, and return it to the Cloud Controller. The created service is unknown to the application.

code is the process of creating the startup script. Here, @ system_envs is the previously analyzed env. exported_system_environment_variables, and @ user_envs is env. exported_user_environment_variables. There are two other scripts: export_buildpack_env_variables_script and start_script. The code for the export_buildpack_env_variables_script script is as follows, which means to execute all sh scripts in a certain path: EXPORT_BUILDPACK_ENV_VARIABLES_SCRIPT = strip_heredoc( The start_scrip
