Discussion:
Is this a BUG REPORT or FEATURE REQUEST?: /kind feature What happened: When use remote container runtime, the remote can't get any PodSandboxImage config set by kubelet What you expected to happen: We want the all container runtime should know what's right PodSandboxImage How to reproduce it (as minimally and precisely as possible): in new node with into k8s cluster kubelet with options expect frakti can create sandbox container with , but get default (k8s version: v1.8.2) Anything else we need to know?: Environment: Kubernetes version (use ):Cloud provider or hardware configuration: bootstrap by kubeadm v1.8.2 OS (e.g. from /etc/os-release): Debian GNU/Linux 9 (stretch) Kernel (e.g. ): SMP Debian 4.9.30-2+deb9u2 (2017-06-26) x8664 GNU/Linux Install tools: kubeadm Others:

good news! thanks!
Issues go stale after 90d of inactivity. Mark the issue as fresh with . Stale issues rot after an additional 30d of inactivity and eventually close. If this issue is safe to close now please do so with . Send feedback to sig-testing, kubernetes/test-infra and/or . /lifecycle stale

Actually we do a no-op when the container runtime is . This is why config can not be set by flag for . In your case, the correct place to change the default sandbox image is in .
