Q&A

K8S 노들에 접근이 안됩니다.

위와 같이 변경후에 접속이 되는걸 확인했습니다. 먼저, VM에서 Port Forwarding이 22000으로 설정되어 있습니다. Vagrantfile 처럼 변경되어있지 않고 있습니다. 두번째는 host port로 접속이 되지않고 22 port로 접속이 되고 있습니다.

ssh 192.168.1.10 60010 The authenticity of host '192.168.1.10 (192.168.1.10)' can't be established. ED25519 key fingerprint is SHA256:Zohb75dEWyRTyVO5EFab2zvgiD4DgzBE7qgBJVPm8uo. This key is not known by any other names.

vagrant up 에러

macOS Monterey에서의 VirtualBox 버그로 headless 모드 대신 아래와 같이 gui 모드로 실행되게 해야 한다고 합니다. 혹시 관련 문제가 있으신 분들은 참조하세요 config.vm.provider "virtualbox" do |vb| vb.gui = true end - https://www.virtualbox.org/ticket/20636#comment:16
