kubernetes - Minikube driver=podman，有没有人能够让它工作？

Question

有没有人能让 minikube 与 --driver=podman 一起工作？

我试过 Fedora 30,31, CentOS7,8, RHEL7,8，结果都一样。

感觉好像需要安装并运行 cri-o。我已经这样做了，但仍然得到相同的结果。

如果需要，我很乐意切换到 Fedora 31 或 CentOS。

更新 2:将 selinux 设置为 permissive 相同的失败。

更新 3:根据@vbatts 的建议，minikube start cmd 非常接近工作。似乎 crio sock 位于/var/run/crio/中，因此我更新了该路径。现在我得到以下...

[root@test ~]# minikube start     --network-plugin=cni     --enable-default-cni     --extra-config=kubelet.container-runtime=remote     --extra-config=kubelet.container-runtime-endpoint=/var/run/crio/crio.sock     --extra-config=kubelet.image-service-endpoint=/var/run/crio/crio.sock     --driver=podman

首先确保你配置了Minikube正确:minikube-configuration .

您必须指定网络插件并启用它，添加运行时的图像服务端点也很重要:/var/run/crio/crio.sock :

$ sudo minikube start \
    --network-plugin=cni \
    --enable-default-cni \
    --extra-config=kubelet.container-runtime=remote \
    --extra-config=kubelet.container-runtime-endpoint=/var/run/crio.sock \
    --extra-config=kubelet.image-service-endpoint=/var/run/crio.sock \
    --driver=podman

请看: minikube-crio-podman , crio-minikube .
