# devstar-devcontainer-kubebuilder-scaffold

DevStar DevContainer CRD 脚手架工程

## Description

本工程是 DevStar Studio 项目的子工程，专用于定制 k8s CRD (Custom Resource Definition) 资源及其自定义 Controller
- **CRD 封装**：将 StatefulSet, Service, Ingress 打包部署
- **Self-Healing**：当 DevContainer 意外终止或运维人员意外删库，该组件能够自动重新拉起对应的资源，保证服务的持续交付

## Getting Started

### Prerequisites
- go version v1.22.0+
- docker version 17.03+.
- kubectl version v1.11.3+.
- Access to a Kubernetes v1.11.3+ cluster.

### To Deploy on the cluster
**Build and push your image to the location specified by `IMG`:**

```sh
make docker-build docker-push IMG=<some-registry>/devstar-devcontainer-kubebuilder-scaffold:tag
```

**NOTE:** This image ought to be published in the personal registry you specified.
And it is required to have access to pull the image from the working environment.
Make sure you have the proper permission to the registry if the above commands don’t work.

**Install the CRDs into the cluster:**

```sh
make install
```

**Deploy the Manager to the cluster with the image specified by `IMG`:**

```sh
make deploy IMG=<some-registry>/devstar-devcontainer-kubebuilder-scaffold:tag
```

> **NOTE**: If you encounter RBAC errors, you may need to grant yourself cluster-admin
privileges or be logged in as admin.

**Create instances of your solution**
You can apply the samples (examples) from the config/sample:

```sh
kubectl apply -k config/samples/
```

>**NOTE**: Ensure that the samples has default values to test it out.

### To Uninstall
**Delete the instances (CRs) from the cluster:**

```sh
kubectl delete -k config/samples/
```

**Delete the APIs(CRDs) from the cluster:**

```sh
make uninstall
```

**UnDeploy the controller from the cluster:**

```sh
make undeploy
```

## Project Distribution

Following are the steps to build the installer and distribute this project to users.

1. Build the installer for the image built and published in the registry:

```sh
make build-installer IMG=<some-registry>/devstar-devcontainer-kubebuilder-scaffold:tag
```

NOTE: The makefile target mentioned above generates an 'install.yaml'
file in the dist directory. This file contains all the resources built
with Kustomize, which are necessary to install this project without
its dependencies.

2. Using the installer

Users can just run kubectl apply -f <URL for YAML BUNDLE> to install the project, i.e.:

```sh
kubectl apply -f https://raw.githubusercontent.com/<org>/devstar-devcontainer-kubebuilder-scaffold/<tag or branch>/dist/install.yaml
```
