使用 Kompose 将 docker-compose 转换为 kubernetes

Question

我是 Kubernetes 的新手，我看到有一种方法可以运行 Kompose，但我收到了这个错误：

root@master-node:kompose --file docker-compose.yml --volumes hostPath up
INFO We are going to create Kubernetes Deployments, Services and PersistentVolumeClaims for your Dockerized application. If you need different kind of resources, use the 'kompose convert' and 'kubectl create -f' commands instead.

FATA Error while deploying application: Error loading config file "/etc/kubernetes/admin.conf": open /etc/kubernetes/admin.conf: permission denied

ls -l /etc/kubernetes/admin.conf
-rw------- 1 root root 5593 Jun 14 08:59 /etc/kubernetes/admin.conf

我怎样才能使这个工作？

系统信息： Ubuntu18 客户端版本：version.Info：主要：“1”，次要：“21”

我也试过让它像那样工作：

kompose convert --volumes hostPath
INFO Kubernetes file "postgres-1-service.yaml" created
INFO Kubernetes file "postgres-2-service.yaml" created
INFO Kubernetes file "postgres-1-deployment.yaml" created
INFO Kubernetes file "postgres-2-deployment.yaml" created
kubectl create -f postgres-1-service.yaml,postgres-2-service.yaml,postgres-1-deployment.yaml,postgres-1-claim0-persistentvolumeclaim.yaml,postgres-1-claim1-persistentvolumeclaim.yaml,postgres-2-deployment.yaml,postgres-2-claim0-persistentvolumeclaim.yaml

我只在 postgres-1-deployment.yaml 和 postgres-2-deployment.yaml.

上遇到这个错误

service/postgres-1 created
service/postgres-2 created
persistentvolumeclaim/postgres-1-claim0 created
persistentvolumeclaim/postgres-1-claim1 created
persistentvolumeclaim/postgres-2-claim0 created

kompose 翻译 deploy.yml 文件的方式有误吗？我做了一切，比如在 kompose guid

Answer 1

认为问题是 Kompose 翻译的 env 值 true 没有引号 "true" 使用了这个验证器 https://kubeyaml.com/
