Buildpack concept

ℹ️ Information
Buildpacks have nothing in common with buildpacks.io. Your Code will not be built into the running image but mounted read-only into the running image.

Buildpacks are defined as a set of three containers:

stateDiagram-v2
direction LR
    [*] --> Fetch
    Fetch --> Build
    Build --> Run
    Run --> [*]        

Loading

Fetch (init container)

Fetches the code from a Git repository. There is a working fetch container from kubero. But if you wish to build your own, you are free to change it in the buildpack configuration.

Build (init container)

Runs the build commands. You can define which image will be used by selecting the buildpack. The buildpack can be configured with any Docker image.

Run (container)

Run the final container In the run stage, there are two options: worker and web. Only the web pod is attached to the ingress and will be accessible from outside the cluster.

Deployment

Deploy your application via UI

1. Create a pipeline with stages and connect it with your git repository This step will create the Namespaces, and configure the webhooks and deploymentkey in your repository (only if it is owned by you)

2. Create an app in every stage.

Deploy your application with kubectl (Infrastructure as Code)

Your application requires 2 custom resource definitions.

1. Apply your changes with kubectl
