Aliaksandr Prysmakou

Out of the box, Cloud Foundry doesn’t give us the ability to control application placement or to specify a target host(s) for an application. This may be critical when one needs to separate apps between different environments or host types—or for any other type of app segregation. The good news is that this can be resolved very easily.

Introducing a One-Click Button for Deploying to GE Predix

Stas Turlo

deploy_to_ge_predix_button

Do you have a sample app built for Predix that you want to share with others? In the past, you had to describe how to clone a Git repo step-by-step, set up build tools, and provide a Cloud Foundry script for pushing your app to the platform.

Today, we’re introducing the functionality for implementing the “Deploy to Predix” button, which automates the process. This button can be embedded in any README file, blog, article, web page, etc., linking to a publicly visible GitHub repository. It makes your audience immediately productive, deploying a copy of your app into their own Predix accounts—with a single click.

Below, we cover how to create the button for your own app and also explain what happens when a developer clicks it.
