[Kubernetes] 0.사전 작업

 

## CentOS 8 Stream 기준

## 테스트 환경은 Master Node 1대, Worker Node 3대로 구성

 

## 아래 내용은 전체 Node에서 수행

1. Static IP Address 설정

# cat /etc/sysconfig/network-scripts/ifcfg-ens192 TYPE=Ethernet PROXY_METHOD=none BROWSER_ONLY=no BOOTPROTO=static DEFROUTE=yes IPV4_FAILURE_FATAL=no IPV6INIT=yes IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes IPV6_FAILURE_FATAL=no NAME=ens192 UUID=60fc619e-6a26-4f31-bfc2-bd4e48130d0e DEVICE=ens192 ONBOOT=yes IPADDR=###.###.###.### NETMASK=###.###.###.### GATEWAY=###.###.###.### # nmcli con down ens192 # nmcli con up ens192

 

2. Hostname 변경

# sudo hostnamectl set-hostname master01 # sudo hostnamectl    Static hostname: master01          Icon name: computer-vm            Chassis: vm         Machine ID: 33d1393482f8498aac174b10376a69c1            Boot ID: d61232b646ef4bdf8dc6f4b6ed8f0bc7     Virtualization: vmware   Operating System: Red Hat Enterprise Linux 8.4 (Ootpa)        CPE OS Name: cpe:/o:redhat:enterprise_linux:8.4:GA             Kernel: Linux 4.18.0-305.el8.x86_64       Architecture: x86-64

 

3. /etc/hosts 변경

## Master와 Worker Node Static IP Address를 이용한 Record 추가
