📌 SAA 준비

📙 EBS, 인스턴스 스토어

시험준비 - ebs와 인스턴스 스토어.
인스턴스 스토어는 성능위주. ebs는 가용영역 안에서만 사용 가능.

📙 s3 수명주기 전환 정책 표

📌 ansible CI/CD

📌 ansible

📙 인스턴스 생성

이름 : ansible-server
이미지 : amazon linux 2
유형 : t2.micro
키페어 선택
네트워크 : MY-VPC, PUB2A
보안그룹 : DEV-SG
사용자데이터 : 

#!/bin/bash
timedatectl set-timezone Asia/Seoul
hostnamectl set-hostname ansible-server
amazon-linux-extras install -y ansible2
amazon-linux-extras install docker -y
systemctl enable --now docker
curl https://raw.githubusercontent.com/docker/docker-ce/master/components/cli/contrib/completion/bash/docker -o /etc/bash_completion.d/docker.sh
usermod -a -G docker ec2-user

📙 route53 레코드 생성으로 도메인 할당

📙 mobaxterm으로 진입하여 설치 확인

[ec2-user@ansible-server ~]$ ansible --version
ansible 2.9.23
  config file = /etc/ansible/ansible.cfg
  configured module search path = [u'/home/ec2-user/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/site-packages/ansible
  executable location = /usr/bin/ansible

  [ec2-user@ansible-server ~]$ docker version
Client:
 Version:           20.10.13
 API version:       1.41

📙 젠킨스가 패스워드로 앤서블에 접속할 수 있게하기

sudo passwd ec2-user
sudo vi /etc/ssh/sshd_config
PasswordAuthentication yes
#PermitEmptyPasswords no
#PasswordAuthentication no
sudo systemctl restart sshd

📙 도커와 앤서블 연결하기 위해 인벤토리 편집

도커호스트의 내부 IP를 앤서블 인벤토리에 넣어주기 

# sudo vi /etc/ansible/hosts
10.14.40.211

📙도커와 앤서블 연결을 위한 키 생성

키 만들기 전에는 진입하려면 비밀번호를 수동으로 쳐줘야함.

[ec2-user@ansible-server ~]$ ansible all -m ping -k
SSH password:
[WARNING]: Platform linux on host 10.14.40.211 is using the discovered Python
interpreter at /usr/bin/python, but future installation of another Python
interpreter could change this. See https://docs.ansible.com/ansible/2.9/referen
ce_appendices/interpreter_discovery.html for more information.
10.14.40.211 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    },
    "changed": false,
    "ping": "pong"
}

키 생성

[ec2-user@ansible-server ~]$ ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/ec2-user/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:

카피명령어로 연결, 다시 ping으로 키진입해보기.

# ssh-copy-id 10.14.40.211

# ansible all -m ping

command 모듈(연결된 도커서버 명령어 실행시킬 수 있는 모듈), uptime 사용으로도 확인가능.

[ec2-user@ansible-server ~]$ ansible all -m command -a uptime

->이런모습으로 도커호스트를 앤서블로 컨트롤 할 것.
command, shell 에서 아쉬운 것은 멱등성이 없음.

📌 jenkins와 앤서블 연결

📙 ansible server

[ec2-user@ansible-server ~]$ sudo mkdir /opt/docker
[ec2-user@ansible-server ~]$ sudo chown -R ec2-user:ec2-user /opt/docker

📙 jenkins

젠킨스대시보드 - 젠킨스 관리 - 시스템설정 - 맨 하단 SSH server 추가

고급 - Use password authentication, or use a different key 체크 - Passphrase / Password 에 비밀번호 입력

📌 빌드

📙 ansible item

jenins 대시보드 - 새로운 item - name:Copy_Artifacts_onto_Ansible -
copy from : BuildAndDeployOnContainer - OK

설명 : 메이븐으로 코드를 빌드하고 앤서블을 활용해서 도커호스트로 배포하자
git 경로 : https://github.com/mangjini/hello-world.git

빌드유발 - poll SCM 체크 해제 (자동화 해제) ; test

빌드 후 조치 - SSh server name : ansible-server로 선택 (기존 : docekr host)
exec command에 있던 내용 삭제 - apply , 저장

[ec2-user@ansible-server docker]$ sudo vi /etc/ansible/hosts
[docker-host]
10.14.40.211

[ansible-server]
10.14.9.46

-> 자기자신도 키 등록해주고, 권한 설정 해줘야 핑 나감.

[ec2-user@ansible-server docker]$ ssh-copy-id 10.14.9.46
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/home/ec2-user/.ssh/id_rsa.pub"

ec2-user@10.14.9.46's password:

Number of key(s) added: 1

Now try logging into the machine, with:   "ssh '10.14.9.46'"
and check to make sure that only the key(s) you wanted were added.

방금 업로드라고 바뀐 모습 ( 구성 수정 정상작동 확인 )

제대로 확인하기 위해 docker hub에서 mytomcat 리포 삭제 .
ansible 서버에서도 이미지 삭제.
