4. Log into an OpenShift cluster, then run the following command.

```

At this point you should have 4 projects created (`basic-spring-boot-build`, `basic-spring-boot-dev`, `basic-spring-boot-stage`, and `basic-spring-boot-prod`) with a pipeline in the `-build` project, and our [Spring Rest](https://github.com/redhat-cop/spring-rest) demo app deployed to the dev/stage/prod projects.

A _build template_ is provided at `.openshift/templates/build.yml` that defines all the resources required to build our java app. It includes:

* A `Tekton` pipeline and associated objects.
* A `BuildConfig` that defines a `Source` build with `Binary` input. This will build our image.

Deploy the pipeline template in build only.

$ oc process -f applier/templates/build.yml -p=APPLICATION_NAME=basic-spring-boot

## Running the pipelines

Once you have deployed the needed infrastructure either with applier or manually, you can run the pipeline by issuing the following command:

```shell
oc project basic-spring-boot-build
tkn -n basic-spring-boot-build pipeline start basic-spring-boot-pipeline -r basic-spring-boot-git=basic-spring-boot-git -s tekton
$ tkn pipeline start basic-spring-boot-pipeline \
-r basic-spring-boot-git=basic-spring-boot-git -s tekton \
-n basic-spring-boot-build
```

## Cleanup

Cleaning up this example is as simple as deleting the projects we created at the beginning.

```shell
oc delete project basic-spring-boot-build basic-spring-boot-dev basic-spring-boot-prod basic-spring-boot-stage
$ oc delete project basic-spring-boot-build basic-spring-boot-dev basic-spring-boot-prod basic-spring-boot-stage
```
