> Using a more recent CNI spec (0.4.0) seems to overcome the existing incompatibility. run this command，paste the result: ``` ls -l /var/lib/cni/ ls -l /var/lib/cni/networks/ ls -l /var/lib/cni/flannel/ ```

This breaks the rules, the `controlPlaneEndpoint` maybe a domain, if this is a domain, so it will not run ok after your code

Both kube-scheduler and kube-controller-manager can use localhost and loadblance to connect to kube-apiserver, but users cannot be forced to use localhost, and warnning can be used instead of error

``` apt-get install python python-pip pip install --no-cache-dir setuptools==20.7.0 pip install xxx ```

Built-in and non-built-in packages should be separated and the built-in packages placed first 内置包和非内置包应该要分开，内置包放在前面，自己的外部包放后面，例如 ``` import ( "fmt" "net/http" "github.com/containers/podman/v2/libpod/define" "github.com/containers/podman/v2/pkg/domain/entities" "github.com/pkg/errors" log "github.com/sirupsen/logrus" ) ```
