ubuntu 에 docker 이후 Kubernetes 설치 kubeadm init

우선 아래와 같이 hosts 를 변경했다.

 

/etc/hosts

 

127.0.0.1       localhost
10.100.0.104    Master.duck.pe.k        Master
10.100.0.105    node1.duck.pe.k         node1
10.100.0.106    node2.duck.pe.k    node2

 

 

apt-get update

apt-get install -y openssh-server curl vim tree

apt-get update -y

systemctl status sshd

    lsb-release
 sudo mkdir -p /etc/apt/keyrings
 curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

 

echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) stable" | tee /etc/apt/sources.list.d/docker.list > /dev/null
apt-get update

 

apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin

net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
EOF
sysctl --system
systemctl stop firewalld 
systemctl disable firewalld

B .우분트에 쿠버네티스 설치.
