Steps:
1. Once you have deployed Pivotal Build Service, the
pb CLI can be used to target it with the following command.Note: Use the --skip-ssl-validation flag if the Pivotal Build Service targets a UAA that has a self-signed CA cert
$ pb api set https://pbs.picorivera.cf-app.com --skip-ssl-validation
Successfully set 'https://pbs.picorivera.cf-app.com' as the Build Service
2. Login using "pb login" as shown below
$ pb login
Target Build Server at: https://pbs.picorivera.cf-app.com
Username: papicella@gmail.com
Password: ******
Login successful
Using the Pivotal Build Service (PBS) requires us to create a TEAM and IMAGE. Both are explained below.
TEAM: A team is an entity on Pivotal Build Service that is used to manage authentication for the images built by Pivotal Build Service and to manage registry and git credentials for the images managed by the team
3. Create a TEAM yaml as per below and then apply that config using the pb cli
example-team.yaml
name: example-team-name
registries:
- registry: index.docker.io
username: pasapples
password: *****
repositories:
- domain: github.com
username: papicella
password: *****
$ pb team apply -f example-team.yaml
Successfully applied team 'example-team-name'
IMAGE: An image defines the specification that Pivotal Build Service uses to create images for a user.
4. Create a IMAGE yaml as per below and then apply that config using the pb cli. The PBS will automatically kick off a build.
example-image.yaml
team: example-team-name
source:
git:
url: https://github.com/papicella/pbs-demo
revision: master
image:
tag: pasapples/pbs-demo-image
$ pb image apply -f example-image.yaml
Successfully applied image configuration 'pasapples/pbs-demo-image'
$ pb image builds pasapples/pbs-demo-image

6. So after a few minutes or so we will see we have built our initial image from the GitHub repo and that OCI compliant image built using Cloud Native Buildpacks is created on our DockerHub account

One of the PBS job is to keep this image updated as new successful commits occur off the matser branch. Lets show how this works as per below
7. Let's make a change to the code for or GitHub repo here I do this in IntelliJ IDEA
8. Commit the changes as shown below
9. Let's see if indeed the PBS actually started a new build for us and we should see it is doing that.
$ pb image builds pasapples/pbs-demo-image

10. We can tail the logs as shown below and actually tail the build logs live using "-f"

11. This time the build will be faster given we are using Cloud Native Buildpacks a CNCF project and it will only rebuild the layers required versus the whole image itself. You can see from the time taken of build "2"

Hopefully this demo shows what the PBS is all about and how it will simplify how you create and keep updated your OCI compliant images.
More Information:
1. Get started with Pivotal Build Service.
https://github.com/pivotal-cf/docs-build-service/blob/master/using.md
2. Request alpha access to Build Service via this form, or by reaching out to your account team. Once you’ve gained access, you’ll see the bits on up PivNet
3. Cloud Native buildpacks
