Cloud Foundry Security: Achieving PCI DSS Compliance

Aliaksandr Prysmakou

Evaluating Cloud Foundry Against the PCI DSS Security Standard

Cloud Foundry adopters come from all areas, including the highly regulated healthcare, finance, and public sectors. A common question is, “Can an open-source platform comply with security standards accepted in our industry?” In this post, I evaluate Cloud Foundry against the requirements of PCI DSS v3.1, a security standard widely used in the financial industry.

Cloud Foundry Containers: Warden, Docker, and Garden

Maksim Zhylinski

Warden is a container implementation currently used in Cloud Foundry. At the same time, Docker is another option to easily and efficiently manage containers. That’s why a lot has been made to enable Docker in the Diego runtime.

Here, I briefly compare Warden and Docker: their implementation, what makes them alike/different, and how they’ll work together in Garden—the new container back end that will become available in Diego.

How to Add BOSH Support to a Custom Cloud (Part 2): External BOSH CPIs

Alexander Lomov

Part 1 | Part 2

bosh_cpi_icon_200

Until recently, all custom BOSH CPIs were forks of the BOSH project. They were hard to maintain and had to be implemented in Ruby. In August 2014, the BOSH team introduced the new external CPI mechanism that has removed these constraints. The second part of our blog series on adding BOSH support to custom clouds will be dedicated to external BOSH CPIs, how they are used, and what it takes to build one.

How to Remotely Debug Cloud Foundry Apps

Juan Pablo Genovese

How to remotly debug Cloud Foundry applicationsWhen using Cloud Foundry for deploying apps, one might expect that all the test suites will run painlessly and what works in development/testing/staging will work in production. However, what if it won’t? What if it is impossible to replicate those conditions in a non-production environment? Here, remote debugging comes to the rescue.

In this blog post, I provide guidelines on how to remotely debug Ruby and Java applications deployed with Cloud Foundry.

Are Diego and Docker Really Good Friends?

Lev Berman

cloud-foundry-docker

Support for Docker is one of the main advantages of Cloud Foundry Diego, but how far does this compatibility go? Is it possible to push an arbitrary image from the Docker Hub to Diego and, if not, what are the constraints? What’s going to change in the future? Finally, why should anyone want to use Diego with Docker at all?

In this post, I’ll answer all of these questions, as well as show how to customize and push the official Redis image and demonstrate how to turn it into a simple service to be consumed by other apps.

How to Add BOSH Support to a Custom Cloud (Part 1): BOSH Components

Alexander Lomov

Part 1 | Part 2

how-to-add-bosh-support-to-a-custom-cloud-smallThe Cloud Foundry PaaS was designed to provide cross-cloud portability and compatibility. BOSH is the official orchestration and deployment tool for CF that makes these features possible. Currently, there is a set of cloud platforms that are able to work with BOSH, but it can be extended to work with clouds that are not on this list.

In this blog series, we’ll go through all the steps necessary to add BOSH support for a new cloud: from CPI implementation to generating a stemcell.

Cloud Foundry Internals: How to Create Custom BOSH CLI Plugins

Alexander Lomov

cf-bosh-cli-custom-pluginAn ability to easily extend core functionality is a key for any system’s evolution. Every popular config management or cloud orchestration tool offers a handy and effective way to do so. For instance, knife plugins in Chef, custom functions in Puppet, and terraform plugins. Being a complex tool, BOSH also provides out-of-the-box utilities for the purpose. The best option for extending BOSH functionality are plugins for a command-line interface (CLI). In fact, major part of the BOSH command-line utilities are implemented as BOSH plugins: the standard BOSH commands, MicroBOSH, BOSH AWS plugin, etc.

Unfortunately, there is no official documentation available on how to create a custom BOSH plugin by yourself, so I decided to compile such a tutorial. In this blog post, I provide guidelines on how to create a custom plugin for BOSH CLI to push the boundaries of the BOSH functionality and significantly boost resolution of application tasks.
