我目前正在使用Kompose(http://www.kompose.io)将docker-compose配置转换为kubernetes配置文件,从而在kubernetes集群上部署项目。
这是我大学的一个硕士类项目,他们负责kubernetes集群,因此我几乎可以确定它的配置正确。仅供参考,这是该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)
我的问题如下。我使用命令kompose convert可以正常工作,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。我一直在寻找也有此问题的其他人,但对我发现的内容并没有真正帮助。
这是我现在的docker-compose文件:
(我知道我不应该在docker-compose文件中放置密码,但这不是问题的一部分)

任何人都有关于如何解决此问题或如何解决此问题的提示?
更新:
这些是
kompose convert
命令生成的文件最佳答案
我已经解决了此问题,方法是将部署文件中的所有apiversions从v1beta2替换为apps / v1,并为每个部署添加了选择器。
selector:
matchLabels:
app: ...
然后,我没有使用
Kompose up
命令进行部署,因为这给了我一个错误,但是我使用了kubectl create -f <file(s)>
命令进行部署,并且成功完成了而没有连接错误。仍然有一些 pod 崩溃,但我认为这与原始问题无关。关于docker - 无法使用Kompose部署到Kubernetes集群,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/59690266/
