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, services, service instances, user roles, and so on.ArchitectureCloud_controller_ng Frame

The learning process of a cainiao coder, named cainiao coder I am a newbie and I am a junior at a well-known school. I spent a semester in my freshman year. I begged my family to have a 3 K computer, at that time, I found that I could not go on like this anymore. I often thought of what my dad said to me: "I can go to high school after I graduated from junior high school, and I can also go to high school af

With the rise of cloud computing, many vendors have launched their own cloud computing platforms, such as VMware, Amazon, Google, and Microsoft. This article introduces Cloud Foundry, a Cloud computing platform of VMware, and uses Node. js + MongoDB to build a Cloud Foundry-based project. Required knowledge: Use of Node. js and NPM command lines. Node. js syntax. MongoDB syntax. Mongoose syntax. Environment

As an outstanding PAAs platform in the industry, cloud foundry has made great achievements in application scalability. In details, when an application needs to be scaled horizontally, cloud foundry can easily help users do a good job of stretching, that is, to create multiple instances of an application, and the status of multiple instances is equal, multiple instances serve users together, and multiple in

The architecture of cloud foundry core components is as follows: Main components: Cloud Controller:It is essentially a server that interacts with the STS. After receiving commands, it sends messages to each module quickly, managing the operation of the entire cloud, which is equivalent to the cloud foundry brain. DEA: Handles access requests to the deployed app. The essence is to package and access

Cloud Foundry provides a service instance is essentially access information: IP, port, user name, password, etc., the use of the process of course can be written dead in the code or configuration file, but the advanced way of course is to let the program automatically according to the environment to adapt the service instance information, switch database, message middleware, Location of code connections such as cloud storage. This article first descri

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 warden container and runs the application instanc

Label: style blog HTTP Io OS SP file data Div Services: The cloud foundry service module is an independent plug-in module from the perspective of source code control, so that third parties can integrate their services into the cloudfoundry ecosystem. On GitHub, we can see that the service is a repository independent from the cloudfoundry core project vcap, Which is vcap-service. In the service module, the design principle is to facilitate third-party

In cloud foundry V2, when an application user needs to start an application instance, the user sends a request to the Cloud Controller through cf cli, And the Cloud Controller forwards the request to the DEA through NATs. The main task of running the startup is DEA. DEA is to start a warden container, copy the content such as droplet into the container, and finally configure the specified environment variable, start the application startup script unde

In Cloud Foundry v2, when an app user needs to launch an instance of the app. The user sends a request to the cloud controller via the CF CLI, and the cloud controller forwards the request to the DEA via Nats. The real start-up is Dea,dea's main job is to start a Warden container, and copy the droplet and other content into the container interior. Finally, the specified environment variables are configured to start the app's startup script under these

There are two main types of requests for accessing the router: management commands from vmcclient or STS. These requests are routed to the applife management component, also known as the cloudcontroller component; the second type is the external request to access your deployed apps. This part of requests will be routed to
