docker - 无法使用 Kompose 部署到 Kubernetes 集群

Question

我目前正在通过使用 Kompose (http://www.kompose.io) 将 docker-compose 配置转换为 kubernetes 配置文件，在 kubernetes 集群上部署一个项目。

这是我大学的一个大师类项目，他们负责 kubernetes 集群，所以我几乎可以肯定它的配置是正确的。仅供引用，这是 Kubernetes 集群的版本；

$ kubectl version
Client Version: version.Info{Major:"1", Minor:"16", GitVersion:"v1.16.3", GitCommit:"b3cbbae08ec52a7fc73d334838e18d17e8512749", GitTreeState:"clean", BuildDate:"2019-11-13T11:23:11Z", GoVersion:"go1.12.12", Compiler:"gc", Platform:"linux/amd64"}
Server Version: version.Info{Major:"1", Minor:"16", GitVersion:"v1.16.3", GitCommit:"b3cbbae08ec52a7fc73d334838e18d17e8512749", GitTreeState:"clean", BuildDate:"2019-11-13T11:13:49Z", GoVersion:"go1.12.12", Compiler:"gc", Platform:"linux/amd64"}

这是 Kompose 的版本；

$ kompose version
1.20.0 (f3d54d784)

我遇到的问题如下。我使用命令 kompose convert 并且没有任何问题，但是当我尝试使用命令 kompose up 部署它时，它失败并显示以下错误消息。

FATA Error while deploying application: Get http://localhost:8080/api: dial tcp [::1]:8080: connect: connection refused

这是我第一次使用 kubernetes 和 kompose。我一直在寻找也有这个问题的其他人，但对我的发现没有任何帮助。

这是我目前的 docker-compose 文件:
(我知道我不应该在我的 docker-compose 文件中输入密码，但这不是问题的一部分)

有人对如何解决此问题或如何解决此问题有任何提示吗？

更新:

这些是 kompose convert 生成的文件命令

Answer 1

我通过将部署文件中的所有 apiversions 从 v1beta2 替换为 apps/v1 并为每个部署添加一个选择器来解决它。

selector:
    matchLabels:
      app: ...

然后我没有使用命令 Kompose up部署，因为这给了我一个错误，但我使用了命令 kubectl create -f <file(s)>部署，这成功了，没有连接错误。仍然有一些 pod 崩溃，但我认为这与这个原始问题没有任何关系。
