Node.js Build Packs

WIP build pack to use Red Hat Node.js ubi images.

Current usage is as outlined in the sections which follow.

Ensure docker or podman is installed

If these are not already installed, install docker or podman based on the process for your operating system.

Install Pack

Buildpacks depend on Pack. Install following the instructions here: https://buildpacks.io/docs/tools/pack/

Suitable build images

No suitable build images exist today with the appropriate metadata needed for the buildpacks. You will need to create these images by doing the following:

cd create-images
bash create-images.sh

This will create fixed images to which the buildpack metadata has been added. These images are:

REPOSITORY TAG ubi8/nodejs-14-fixed latest ubi8/nodejs-14-minimal-fixed latest

Create builder

To create the builder that will include the buildpack do the following:

• cd builders
• execute bash create.sh X Y -fixed where X is the ubi version you want to use and Y is the Node.js version you want to use. Currently this should only be ubi 8 and Node.js 14 ie: bash create.sh 8 14 -fixed. You must have prepared a matching image in the step above titled suitable build images.

The output of this step will be a message that tells you how to run the builder which includes the build pack. For example:

user1@user1-VirtualBox:~/demos/buildpacks/builders$ bash create.sh 8 14
Successfully created builder image nodejs-14_ubi-8_builder
Tip: Run pack build <image-name> --builder nodejs-14_ubi-8_builder to use this builder

Use the builder/buildpack

Run the command line suggested by the output of creating the builder in an application directory with a package.json file.

For example using the nodejs-rest-http nodeshift-starter :

• git clone https://github.com/nodeshift-starters/nodejs-rest-http.git
• cd nodejs-rest-http
• pack build test-image --builder nodejs-14_ubi-8_builder
• docker run -p 8080:8080 -d -t test-image

The nodejs-rest-http nodeshift-starter will now be running and you can access it at http://localhost:8080
