Question

안녕하세요 쿠버네티스 설치 후 join.sh에 아무내용이 안나와서 설치과정 확인해보니 아래와같은 에러가 나오는데 어떻게 해결하면될까요.. ? k8s-master: Running provisioner: shell... k8s-master: Running: inline script k8s-master: I0628 11:30:40.411653 14444 version.go:255] remote version is much newer: v1.24.2; falling back to: stable-1.22 k8s-master: [init] Using Kubernetes version: v1.22.11 k8s-master: [preflight] Running pre-flight checks k8s-master: [preflight] WARNING: Couldn't create the interface used for talking to the container runtime: docker is required for container runtime: exec: "docker": executable file not found in $PATH k8s-master: error execution phase preflight: [preflight] Some fatal errors occurred: k8s-master: [ERROR FileContent--proc-sys-net-bridge-bridge-nf-call-iptables]: /proc/sys/net/bridge/bridge-nf-call-iptables does not exist k8s-master: [ERROR FileContent--proc-sys-net-ipv4-ip_forward]: /proc/sys/net/ipv4/ip_forward contents are not set to 1 k8s-master: [preflight] If you know what you are doing, you can make a check non-fatal with `--ignore-preflight-errors=...` k8s-master: To see the stack trace of this error execute with --v=5 or higher k8s-master: failed to load admin kubeconfig: open /root/.kube/config: no such file or directory k8s-master: To see the stack trace of this error execute with --v=5 or higher k8s-master: cp: cannot stat &lsquo;/etc/kubernetes/admin.conf&rsquo;: No such file or directory k8s-master: chown: cannot access &lsquo;/root/.kube/config&rsquo;: No such file or directory k8s-master: Loaded plugins: fastestmirror k8s-master: Loading mirror speeds from cached hostfile

오래된 내용이지만, 해당 문제 해결방법입니다. modprobe br_netfilter echo 1 > /proc/sys/net/bridge/bridge-nf-call-iptables 같은 문제를 겪으신 분들께서 참고하시길 바래요.

안녕하세요 여러번 재설치 했는데 같은 오류가나와서.. 해결방법 또는 제가 어떤부분을 확인해보면될까요..?

안녕하세요. 해당 에러는 통상 아래 설정이 안되있을때 나는 에러입니다. ----------------------- # Iptables 커널 옵션 활성화 cat <<EOF > /etc/sysctl.d/k8s.conf net.bridge.bridge-nf-call-ip6tables = 1 net.bridge.bridge-nf-call-iptables = 1 EOF sysctl --system ----------------------- 근데 제 Vagrantfile 스크립트에 있는 내용이라 제대로 안먹혔을리는 없을것 같은데, 에러해결보다 다 지우시고 다시한번 설치해보시길 권해드려요.
