지금부터 살펴볼 내용은 어쩌면 지금까지 살펴본 다양한 Kubernetes 포스팅의 완결판이 될 수도 있을 것 같습니다.

지금까지 다양한 Component를 살펴보며 Kubernetes가 제공하는 Request Flow에 대해 알아보고 구성해 보았습니다.

다만 각 컴포넌트들을 직접 구성하기에는 자세히 설명을 하였지만 처음 접하는 분들에게는 어려운 과정이 될 것입니다.

이에 누구나 손쉽게 따라 구성해 볼 수 있게 Shell Script와 YAML 파일을 작성해 보았습니다.

이전 포스팅은 아래를 참고해 주시기 바랍니다.

a) Set Env

b) Check the Firewall

c) Check the Selinux

d) Install required pachages

e) Install Docker

f) Add RPM Repository

g) Install Kubernetes

총 7Step으로 이루어져 있습니다.

하나씩 살펴보고 적용해 실제로 적용해 보겠습니다.

a) Set Env

echo "#####" 
echo "##### Set ENV" 
echo "#####"
export k8sRepo=192.168.xxx.xxx 
export dockerRepo=192.168.xxx.xxx

→ 유일하게 직접 수정해야 하는 부분입니다.

K8S Repository 경로를 지정하는 k8sRepo와 docker Repository 경로를 지정하는 dockerRepo로 설정되어 있습니다.

본 포스팅의 시작이 외부망과 차단된 폐쇄망을 기준으로 작성하다보니 각각 위와 같이 변경을 원하는 리포지토리 경로를 지정해 주어야 하지만, 외부 인터넷이 되는 환경에서는 굳이 필요 없는 설정입니다.

 

b) Check the Firewall

echo "#####" 
echo "##### Check the firewall" 
echo "#####" 
count=$(systemctl status firewalld | grep dead | wc -l) 
if(( "${count}" == 0 )); 
then 
        echo "firewalld이 기동되어 있습니다." 
        echo "firewalld를 다운하시겠습니까? (y/n)" 
        read word 
        if [ "${word}" == "y" ]; 
        then 
                systemctl stop firewalld 
                echo "firewalld를 다운하였습니다." 
        else 
                echo "firewalld를 기동된 상태로 시작합니다." 
        fi 
else 
        echo "firewalld가 다운되어 있습니다." 
fi

→ firewalld에 대한 설정을 검증합니다. firewalld 설정을 확인하고 기동되어 있을 경우 다운여부를 결정합니다.

 

c) Check the Selinux

echo "#####"
echo "##### Check the Selinux"
echo "#####"
getSelinux=$(getenforce)
if [ "$getSelinux" = "Disabled" ];
then
        echo "Selinux가 다운되어 있습니다."
elif [ "$getSelinux" = "Permissive" ];
then
        echo "Selinux가 Permissive 모드로 기동되어 있습니다."
elif [ "$getSelinux" = "Enforcing" ];
then
        echo "Selinux가 기동되어 있습니다."
        echo "Selinux를 Permissive 모드로 변경 하시겠습니까? (y/n)"
        read fword
        if [ "${fword}" = "y" ];
        then
                setenfoce 0;
                echo "Selinux를 Permissive 모드로 변경 하였습니다."
        else
                echo "Selinux를 Enforce 모드로 유지하고 기동합니다."
        fi
fi

→ selinux에 대한 설정을 검증합니다. selinux 설정을 확인하고 기동되어 있을 경우 다운여부를 결정합니다.

 

d) Install required packages

echo "#####" 
echo "##### Install required packages" 
echo "#####" 
yum install -y yum-utils device-mapper-persistent-data lvm2 sshpass net-tools 

→ 주요 패키지를 설치합니다.

 

e) Install Docker

echo "#####" 
echo "##### Install Docker" 
echo "#####" 
yum install -y docker 
mv /etc/docker/daemon.json /etc/docker/daemon.json.org 
sed "s/{}/{\"insecure\-registries\"\:\[\"$dockerRepo\"\]}/" /etc/docker/daemon.json.org > /etc/docker/daemon.json 
systemctl daemon-reload 
systemctl restart docker 

→ Kubernetes를 기동할 Docker를 설치하고 기본 설정을 진행합니다. 상단의 SetEnv 정보를 기반으로 docker repository에 http로 접근하기 위한 insecure-registries를 /etc/docker/daemon.json에 추가하며, Docker Process를 재기동합니다.

 

f) Add RPM Repository

echo "#####" 
echo "##### Add RPM Repository" 
echo "#####" 
sed "s/K8SREPO/$k8sRepo/" kube.repo > kubernetes.repo 
mv kubernetes.repo /etc/yum.repos.d/ 
yum clean all 
yum repolist all 

→ Kubernetes 설치를 위한 repository를 yum.repo.d에 반영하고 적용합니다.

 

g) Install Kubernetes

echo "#####" 
echo "##### Install Kubernetes" 
echo "#####" 
yum install -y kubelet kubeadm kubectl --disableexcludes=kubernetes 
echo '1' > /proc/sys/net/bridge/bridge-nf-call-arptables 
echo '1' > /proc/sys/net/bridge/bridge-nf-call-ip6tables 
echo '1' > /proc/sys/net/bridge/bridge-nf-call-iptables 
systemctl enable docker 
systemctl enable kubelet

→ Kubenetes의 주요 모듈을 설치합니다. 이후 docker와 kubelet을 서비스에 enable합니다.

3. Kubetnetes 설치

대부분 인터넷 환경에서 사용한다는 것을 기준으로 ShellScript를 수정하여 하나 더 반영해 드리도록 하겠습니다.

같은 디렉토리(~/kubernetesonestepboot/kubernetes_onestepinstall/)에 1.kubernetesOneStepInstallByInternet.sh을 추가합니다.

[root@kubemaster kubernetes_onestepinstall]# sh 1.kubernetesOneStepInstallByInternet.sh

정리하면 다음과 같습니다.

인터넷 환경에서 Kubernetes를 설치하기 위해서는 다음과 같습니다.


1) Virtual Box 및 CentOS 설치

2) git 설치 (yum install -y git)

3) git repository 다운로드 (git clone https://github.com/sonnaraon/kubernetesonestepboot.git)

4) Shell Script 실행을 위한 이동 (cd $GIT_REPO_HOME/kubernetesonestepboot/kubernetes_onestepinstall/)

5) Shell Script 실행 (sh 1.kubernetesOneStepInstallByInternet.sh)


쉽죠?

이번 포스팅은 여기서 마치고 다음시간에 보다 상세한 설정도 원스텝으로 구성하고 샘플 애플리케이션까지 확인해 보는 시간을 갖도록 하겠습니다.

그전에 과제를 하나 드리자면, 현재 설치한 구성이 Master Node라면 동일한 구성으로 Worker Node로 사용할 VM을 하나 더 생성하고 동일한 설치 과정으로 준비한 이후 다음 포스팅을 보시기를 권고드립니다.
