Deploy an app from Source

In this quickstart tutorial you learn how to deploy an app from your local source code using pack.

The following tools have to be installed in order to perform the upcoming steps:

• Knative CLI Installation
• Pack CLI Installation (opens new window)
• Docker Installation (opens new window)

Steps

1. clone the repo

   $ git clone https://github.com/buildpacks/samples
   

2. go to the app directory

   $ cd samples/apps/java-maven
   

3. build the app

   $ pack build myapp --builder cnbs/sample-builder:bionic
   

   NOTE: This is your first time running pack build for myapp, so you’ll notice that the build might take longer than usual. Subsequent builds will take advantage of various forms of caching. If you’re curious, try running pack build myapp a second time to see the difference in build time.

4. push the newly created image to an existing registry

   $ docker tag myapp:latest harbor.demo.kube-plus.cloud/demo/myapp
   $ docker push harbor.demo.kube-plus.cloud/demo/myapp
   
   Using default tag: latest
   The push refers to repository [harbor.demo.kube-plus.cloud/demo/myapp]

   NOTE: You can either bring your own registry or you can use our Harbor registry: https://harbor.demo.kube-plus.cloud. Click here for more information on how to use our Habor registry.

   or directly with pack --publish while building the image:

   $ pack build harbor.demo.kube-plus.cloud/demo/myapp \
     --builder paketobuildpacks/builder:base \
     --publish
   

   You should now be able to see the image in the on-cluster image registry: https://harbor.demo.kube-plus.cloud (opens new window)

5. Execute the steps described in the Deploy an app from an image to deploy the newly created image with Knative.

   NOTE: In case you don't want to build your image locally, we also offer to use kpack which is an integral part of knative+. Here you can find more information about how to build your image on the cluster.
