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.
• OpenEBS

使用 Helm Chart 安装 OpenEBS

DevStar DevContainer 需要 OpenEBS 进行动态存储分配

helm repo add openebs https://openebs.github.io/openebs
helm repo update
helm install openebs --namespace openebs openebs/openebs --create-namespace

helm ls -n openebs
# NAME   	NAMESPACE	REVISION	UPDATED                               	STATUS  	CHART        	APP VERSION

kubectl get sc

# standard (default)       k8s.io/minikube-hostpath   Delete          Immediate              false                  8d

To Deploy on the cluster

Build and push your image to the location specified by IMG:

make docker-build docker-push IMG=<some-registry>/devcontainer-operator: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:

make install

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

make deploy IMG=<some-registry>/devcontainer-operator: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:

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:

kubectl delete -k config/samples/

Delete the APIs(CRDs) from the cluster:

make uninstall

UnDeploy the controller from the cluster:

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:

make build-installer IMG=<some-registry>/devcontainer-operator: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 to install the project, i.e.:

kubectl apply -f https://raw.githubusercontent.com/<org>/devcontainer-operator/<tag or branch>/dist/install.yaml

Contributing

// TODO(user): Add detailed information on how you would like others to contribute to this project

NOTE: Run make help for more information on all potential make targets
