Openstack Deploy 복구 후 증설

Deploy가 모종의 이유로 유실되었으나, Compute node 증설 요청이 있을 경우 사용하는 방법

 

 

Compute node 증설 외의 Ansible을 통한 openstack service 추가 설치에서는 사용 불가

 

새로운 deploy 노드가 될 서버가 필요

해당 deploy 노드는 openstack ansible github를 clone 해오는 과정까지 진행되어야 하고, 기존 openstack이 사용하던 network에 접속할 수 있어야 함

Configure the deployment — openstack-ansible 28.1.0.dev11 documentation

이 과정 중 Configure the deployment까지 필요한데, 아래 과정은 실행하지 않음

 

cd /opt/openstack-ansible
# ./scripts/pw-token-gen.py --file /etc/openstack_deploy/user_secrets.yml

실행하여도 기존에 사용하던 secret 정보와 달라지기 때문에 의미 없음

 

현재 설정되어 있는 정보들을 바탕으로 컴퓨트 노드를 증설 할 때 필요한 정보들을 수집

컴퓨트 노드의 각 위치의 파일에서 secret 정보 수집하여 /etc/openstack_deploy/user_secrets.yml 에 입력

버전마다 변수 명이 다를 수 있으므로 역할을 잘 상기하며 변수명 확인

 

ex) oslomsg로 되어있는 아래 예시는 다른 버전에서는 rabbitmq_password 같은 변수명으로 저장될 수 있음

기본적으로 rabbitmq에서 사용하는 비밀번호이기 때문에 잘 확인할 경우 문제 없이 찾을 수 있음

컨테이너 이름과 할당된 ip가 필요

 

/opt/openstack-ansible/inventory/dynamic_inventory.py --config /etc/openstack_deploy/ 를 실행시켜 기본 inventory를 생성

vi /etc/openstack_deploy/openstack_inventory.json에서 컨테이너 이름과 ip를 수정

 

이러면 컴퓨트 증설을 위한 준비가 끝나며, 컴퓨트 노드 증설을 위한 작업을 실행
