Unable to deploy flannel #357

Open oscgu opened 8 months ago

oscgu commented 8 months ago

Describe the bug Whenever I try to deploy flannel it keeps crash looping with the following error:

W0104 05:45:01.747597 3296 client_config.go:617] Neither --kubeconfig nor --master was specified. Using the inClusterConfig. This might not work. W0104 05:45:01.748130 3296 client_config.go:622] error creating inClusterConfig, falling back to default config: open /var/run/secrets/kubernetes.io/serviceaccount/token: The system cannot find the path specified. E0104 05:45:01.749443 3296 main.go:226] Failed to create SubnetManager: fail to create kubernetes config: invalid configuration: no configuration has been provided, try setting KUBERNETES_MASTER environment variable

Setting the KUBERNETES_MASTER env variable does nothing.

To Reproduce Build the flannel image, adjust the place-holders in the deployment file and apply it.

Expected behavior No crash loop

Kubernetes (please complete the following information):

Additional info It's a mixed cluster (linux & windows) Same issue when using Containerd 1.7.11

Any solution to this problem? I am having the same issue.

Bump. Ran into the same issue today.

After some searching around, this looks to be the actual issue. Posting for anyone who lands here.

Found the problem. Turns out, the hard-coded /var/run/secrets/kubernetes.io/serviceaccount/ is not supported in contained 1.6. So just install contained 1.7+ and you should be good to go.

Edit:

Seems like OP was using 1.7 so I don't know then. Updating to 1.7 fixed it for me.
