Question

但是，当我运行命令时，我试图在docker-compose.yaml文件上使用kompose convert：

kompose convert -f docker-compose.yaml

我得到了输出：

WARN Volume mount on the host "/home/centos/Sprint0Demo/Servers/elasticSearchConnector/etc/kafka-connect" isn't supported - ignoring path on the host
WARN Volume mount on the host "/home/centos/Sprint0Demo/Servers/elasticSearchConnector/etc/kafka-elasticsearch" isn't supported - ignoring path on the host
WARN Volume mount on the host "/home/centos/Sprint0Demo/Servers/elasticSearchConnector/etc/kafak" isn't supported - ignoring path on the host

它还对其他永久卷显示更多警告

我的docker-compose文件是：

有人知道我如何解决此问题？我以为它与错误消息有关，该错误消息表明它是卷装入还是主机装入？

Answer 1

我做了一些研究，需要指出三点：

kompose不支持在主机上进行卷挂载。您可以考虑改用emptyDir。
Kubernetes使得难以传递host/root卷。您可以尝试 hostPath。 kompose convert --volumes hostPath适用于k8s。
如果您想在一台计算机上运行内容，还可以签出Compose on Kubernetes。

请让我知道是否有帮助。

有没有办法将卷挂载到kubernetes docker compose部署？
