It’s possible to add a custom buildpack to Stackato or Helion Development Platform so that it’s available to all applications. When using an installed buildpack it is not necessary to include a manifest or identify the buildpack. Instead it will be selected by the detect script in the buildpack. All files are on the cloud controller node which eliminates download time and bandwidth. Package the buildpack Prepare your buildpack for installation by adding all files to a zip file (of any name). The bin folder should be in the root of the zip......

In the past PaaS has been rigid and invasive for application developers. CloudFoundry aims to change that perception of PaaS with the use of Buildpacks. A Buildpack allows an application developer to define his deployment environment in plain text. Some refer to this as infrastructure as code since the aspects of a deployment environment that were previously handled by system administrators on dedicated servers now exist in plain text alongside the application files. What’s available out-of-the-box? Before diving into custom buildpacks, a lot of people will ask “What is available out-of-the-box with CloudFoundry?”.......

Previously I detailed the process to create a buildpack for Stackato or Helion, including reconfiguring the buildpack to be self-contained. In both previous examples, the compile script performed a configure and make on source to build the binaries for the application. Since the configure->make process is often slow, this can be done once and the binaries added to the git repository for the buildpack. Pre-compile nginx The first step is to build nginx to run in the docker container for Stackato or Helion. These steps were previously in the compile script, but now......

I previously documented the process to create a buildpack for nginx to use with Stackato or Helion Dev Platform. In that buildpack example, the compile script would download the nginx source using wget. In some cases, the time, bandwidth or access required to download external resources may be undesirable. In those cases the buildpack can be adjusted to work offline by adding the external resources to the git repository. The new structure would look like this. Updated compile script The only bulidpack related file that would need to change to accommodate this is......

CloudFoundry accommodates buildpacks which define a deployment environment. A buildpack is distinct from an application and provides everything the application needs to run, including web server, language runtime, libraries, etc. The most basic structure for a buildpack requires three files inside a directory named bin. The buildpack files discussed in this post can be cloned or forked at https://github.com/dwatrous/buildpack-nginx Some quick points about these buildpack files All three files must be executable via bash Can be shell scripts or any language that can be invoked using bash Explicit use of paths recommended detect......

One of the major strengths of CloudFoundry was the adoption of buildpacks. A buildpack represents a blueprint which defines all runtime requirements for an application. These may include web server, application, language, library and any other requirements to run an application. There are many buildpacks available for common environments, such as Java, PHP, Python, Go, etc. It is also easy to fork an existing buildpack or create a new buildpack. When an application is pushed to CloudFoundry, there is a staging step and a deploy step, as shown below. The buildpack comes in......

I’m about to write a few articles about creating buildpacks for Stackato, which is a derivative of CloudFoundry and the technology behind Helion Development Platform. The approach for deploying nginx in docker as part of a buildpack differs from the approach I published previously. There are a few reasons for this: Stackato discourages root access to the docker image All services will run as the stackato user The PORT to which services must bind is assigned and in the free range (no root required) Get a host setup to run docker The easiest......
