This article provides step-by-step instructions to register and install Predix, GE’s brand name for their “Industrial Internet” sales.
Actions to get started:
- Slack channel setup
- Predix Account setup
- Select an approach to install 3rd-party utilities
- Hosting in the Cloud Foundry cloud
- Local install
- Devbox with pre-built virtual machines
I want you to feel confident that you’ve mastered this skill. That’s why this takes a hands-on approach where you type in commands and we explain the responses and possible troubleshooting. This is a “deep dive” because all details are presented.
Like a good music DJ, I’ve carefully arranged the presentation of concepts into a sequence for easy learning, so you don’t have to spend as much time as me making sense of the flood of material around this subject.
Sentences that begin with PROTIP are a high point of this website to point out wisdom and advice from experience. NOTE point out observations that many miss. Search for them if you only want “TL;DR” (Too Long Didn’t Read) highlights.
Stuck? Contact me and I or one of my friends will help you.
Slack channel setup
Once you receive a confirmation email, activate the Slack app on your Mac or PC if you’d like to switch among differen Slack channels.
Click the “+” at the lower left corner.
Type in the teamdomain of “intelligentworld” and click Continue.
Type in the email you used to register and click Continue.
If you clicked “Send Magic Link”, open the email and click “Sign into Slack”.
That action opens browser for you to click “Launch Slack”.
Choose whether to enable desktop notifications.
Now return temporarily to your browser to close the tabs to access Slack.
Predix Account setup

QUESTION: After the free days, $ ___ per month?
Confirm phone and email while on the page.
A GitHub repo account needs to be specified.
PROTIP: Don’t expect a response if you provide a gmail or hotmail account, even after phone ane email confirmation code confirmations. That’s my personal experience
Wait for the confirm email from Predix. If you’re deemed legitimate:
“Thanks for your interest in a Predix trial account. We’ll validate your information, and will respond within five business days.”
Wait for the email from Predix.
Each developer’s GitHub account is granted access to the repository and a number of subrepositories:
Once approved, you can then enroll in training.
“Please connect to BlueSSO and go to training.predix.io. From there, log in with your Predix credentials and enroll in the “On-Demand” courses. This is where you will find access to the free eLearning videos.”
Note that the training site is different from
After approval, you’ll be able to post on the

Eclipse STS IDE
This advises the use of STS
- Use an interest browser to the STS website.
- Select a download site to begin download. Wait for the file to download.
In Finder, navigate inside the folder, such as:
This contains the server.
Move and/or rename the folder according to your organization’s standards.
- In Finder navigate to /Applications.
- Move (drag and drop) STS.app to /Applications.
- Open STS by double-clicking the icon.
- Click Open icon for first-time confirmation.
- Specify your workspace.
STS (Spring Tools Suite)
Included with STS (Spring Tools Suite) is the developer edition of Pivotal tc Server, the drop-in replacement for Apache Tomcat that’s optimized for Spring.
The Spring Insight console, tc Server Developer Edition, provides a graphical real-time view of application performance metrics that lets developers identify and diagnose problems from their desktops.
The framework is based on the Java Spring framework, which many now consider “heavy”.
This is surprising considering most others in their industry have gone to Python or React.
QUESTION: Why Spring and not Node or Python or React?
Maybe it’s because there are more Java Spring developers unemployed than the other hotter frameworks?
Or that Spring is more “mature” as a framework since it’s been around since the 90’s.
During register for a Predix account, each developer’s GitHub account is granted access to the repository and a number of subrepositories at

Create a service instance with the free plan “turtle”:
cf create-service elephantsql turtle cf-spring-db
Creating service instance cf-spring-db in org montana / space joliet as firstname.lastname@example.org... OK
Bind the newly created service to the app:
cf bind-service cf-spring cf-spring-db
NOTE: When a service is bound to an app, environment variables are stored that allow the app to connect to the service after a push, restage, or restart command.
Binding service cf-spring-db to app cf-spring in org montana / space joliet as email@example.com... OK TIP: Use 'cf restage cf-spring' to ensure your env variable changes take effect
Restart the app:
cf restart cf-spring

Verify the new service is bound to the app:
name service plan bound apps last operation cf-spring-db elephantsql turtle cf-spring create succeeded
Increase the number of app instances from one to two:
cf scale cf-spring -i 2
Check the status of the app and verify there are two instances running:
cf app cf-spring
WARNING: Scaling your app vertically changes the disk space limit or memory limit for each app instance.
Increase the memory limit for each app instance:
cf scale cf-spring -m 1G
Increase the disk limit for each app instance:
cf scale cf-spring -k 512M

Create a folder (~/gits/predix) to hold repos and cd to it.
Predix offers two samples:
- git clone https://github.com/PredixDev/predix-microservice-cf-jsr.git
- git clone https://github.com/PredixDev/predix-microservice-cf-spring.git
Create repo for JSR and cd into it:
git clone https://github.com/PredixDev/predix-microservice-cf-jsr.git
The tree of folders and files for JSR is more complex than Spring:
