1. Knife

Knife는 chef를 제어하기 위한 CLI기반의 툴이다. 관리자는 knife를 이용해서 node, cookbook, roles, databags, envirionments 등 chef의 모든 것을 관리할 수 있다.

Knife도 chef client와 마찬가지로 chef server에서 제공하는 REST API를 이용해서 작업을 한다. chef server와 상호작용하기 위한 CLI 버전이라고 볼 수 있다.

1.1. 테스트 환경

Virtualbox로 두 대의 centos6.3 운영체제를 올려서 chef-server와 chef-client를 설치했다.

1.2. 도움말 시스템

1.3. knife 설정

knife는 chef client와 같은 레벨에서 작동한다. 따라서 chef server API에 접근하기 위한 설정들이 필요하다. knife 설정파일이름은 ~/.chef/knife.rb 이다.

설정 매개변수들은 다음과 같다.

node_name : chef-server 연결과 인증을 위한 client 이름
client_key : chef-server 인증에 사용할 Private key 파일
chef_server_url : chef server의 URL.
chache_type : 기본은 'BasicFile'다. BasicFile, Berkeley, Couch, DataMapper, LMC, Memcache, Memory, MongoDB, Redis, Rufus, S3, SDBM, Tyrant, Xattr, YAML을 지원한다.
cache_option : cache 옵션으로 cache_type에 따라서 달라진다.
validation_client_name
validation_client_key
cookbook_path
cookbook_copyright, cookbook_email, cookbook_license

knife를 사용하려면 knife client 인증 절차가 필요하다.

2. knife sub commands

kinfe에 내장된 서브 명령어들을 정리한다.

2.1. bootstrap

2.2. client

chef API를 사용하기 위해서는 chef cleint로 등록을 해야 한다.

하지만 노드가 처음 만들어진 상태에서 chef-client를 실행하면, 아직 API client 권한을 가지고 있지 않기 때문에 chef server에 요청을 할 수가 없다. 요청을 하기 위해서는 client key 파일을 가지고 있어야 한다. chef 관리자는 knife를 이용해서 client를 등록하고, 이때 만들어진 client key 파일을 배포할 수 있다. 이 key 파일을 이용해서 등록하면 된다. client를 등록하는 또 다른 (일반적인)방법은 chef-validator으로 등록하는 방법이다. 처음 chef-client가 실행되면 clinet는 먼저 client key 파일을 찾는다. 만약 client key 파일이 없다면 validation.pem 파일을 이용해서 등록을 시도한다. validation.pem 파일은 chef-server의 /etc/chef 디렉토리에 있다. validation.pem 파일을 이용해서 등록된 client는 일반 (none-admin) client로 등록된다.

2.2.1. client 타입

Client는 아래의 두 가지 타입이 있다.

Admin API client : 관리자 권한을 가지는 client다. 읽기와 쓰기권한 모두를 가지고 있다. cookbook을 수정하고, node와 client를 등록하고, data bag을 편집할 수 있다.
일반 client : cookbook에 대한 읽기 권한만을 가지는 client다. validation.pem을 이용해서 등록된 client들은 일반 cleint 권한을 가진다. cookbook을 다운로드 받아서 실행할 수 있다.

2.2.2. create

새로운 API client를 등록할 수 있다. 등록하고 나면 API client를 위한 RSA key pair가 만들어진다. Public key는 chef server에 저장되고 Private key는 화면에 출력되거나 파일로 저장할 수 있는데, 이 private key를 client에 배포하면 된다.

chef-client(일반 client)를 위한 private key 파일은 /etc/chef/client.pem으로 복사한다.
Knife(Admin API client)를 위한 private key 파일은 (보통) ~/.chef/client_name.pem 파일로 복사한다.

2.2.2.1. 사용법

사용법은 다음과 같다.

2.3. configure

configure를 이용하면 간단하게 knife.rb와 client.rb 설정파일을 만들 수 있다.

--client DIRECTORY : chef 클라이언트 설정파일을 만들 수 있다.
-i, --initial : API 클라이언트를 초기화 한다. 일반적으로 chef server를 처음 인스톨하고, 이를 관리하기 위한 administrator 클라이언트를 초기화하기 위해서 사용한다.
-r REPO, --repository REPO : chef 저장소 경로

kinfe는 chef server의 자원을 말그대로 칼질하는 관리도구다. 따라서 권한 인증을 위한 private key 파일이 필요하다(여기에서는 yundream.pem). 이제 knife를 이용해서 chef 자원을 요리(읽기/쓰기)할 수 있다.

chef client는 chef server로부터 설정정보를 단지 읽기만 한다. 읽기권한을 획득하기 위해서 역시 chef server의 private key(일반적으로 validation.pem)가 필요하다.

2.4. cookbook

cookbook은 chef에서 배포하고 관리하는 기본설정 단위다. cookbook에는 애플리케이션과 운영체제를 설정하기 위한 모든 정보를 가진다.

cookbook sub command의 사용방법은 다음과 같다.

2.4.1. create

create를 이용해서 새로운 cookbook을 만들 수 있다. cookbook을 생성하면 로컬 디렉토리에 cookbook을 위한 디렉토리가 만들어진다. 이 디렉토리에는 다음과 같은 파일들이 놓인다.

cookbook/attributes
cookbook/definitions
cookbook/files/default
cookbook/libraries
cookbook/metadata.rb
cookbook/providers
cookbook/readme.md
cookbook/recipes/default.rb
cookbook/resources
cookbook/templates/default

create로 만든 cookbook은 knife upload로 chef server에 업로드할 수 있다.

2.5. node

Node는 chef-client가 설치된 모든 서버로 물리적인 서버와 (클라우드 기반의)가상화 서버까지 포함하나. chef는 물리 노드와 가상화 노드의 조합으로 이루어진다. chef-client는 각 노드에서 실행되며, Ohai를 이용해서 클라이언트 시스템에 대한 정보를 수집한다.

Chef server는 node의 sub command를 이용해서 노드들을 관리한다.

-r, --run-list : run-list만 보여준다.

-l 옵션을 사용할 경우 ohai를 이용해서 노드의 시스템과 네트워크에 대한 구체적인 정보를 보여준다. 이 내용만을 가지고도 시스템 구성정보를 보여줄 수 있을 것이다.

ohai를 모니터링 도구로까지 확장할 수 있을 것 같은데... 고민해봐야 겠다.

chef databag 참고

2.8. environment

2.9. exec

fdsfsfwewwd

2.10. role

chef role은 여기에서 정리한다. 나중에 문서위치를 변경해야 겠다.

2.11. search

chef는 apache solr 기반의 풀 텍스트 검색엔진을 가지고 있다. chef 개발자는 solr 검색엔진이 제공하는 강력한 검색 기능을 활용할 수 있다.

chef는 databags, API clients, nodes, roles의 모든 데이터를 색인한다.

2.11.1. Search 색인 테이블 이름

chef는 아래의 색인 테이블 이름을 가지고 있다.

Data type	색인 테이블 이름	검색 예제
Roles	role	knife search role "name:production*"
Nodes	node	knife search node "name:app*"
API Clients	client	knife search client "name:c*"
Environments	environment	knife search environment ":"

데이터 백은 데이터 백의 이름으로 색인테이블이 만들어진다. 예를 들어 데이터 백 이름이 'bag_o_data'라면, 질의어는 대략 아래와 같다.

1
# knife search bag_o_data "arbitrary_key:some_value"

2.13. ssh

chef에 등록된 노드들에 대해서 ssh로 명령을 수행할 수 있다. 개인적으로 설정이 변경된 노드의 chef-client를 재시작하기 위해서 주로사용한다. 사용법은 아래와 같다.

옵션 들

-a, --attribute SSH_ATTR : SSH 연결에 사용 할 attribute를 지정한다. 기본값으로 FQDN이 사용되며, ipaddress와 hostname을 사용할 수 있다. chef client를 등록할때, 호스트의 fqdn 이름을 이용하지 않고 chef-client -N 옵션으로 등록할 수도 있다. 이 경우 fqdn을 이용하면 제대로 접속이 안되므로 -a 옵션을 사용해야 한다.
-P, --ssh-password PASSWORD : SSH 패스워드
-x, --ssh-user USERNAME : SSH 유저이름
-i, --identity-file IDENTITY_FILE : 인증에 사용할 ssh key 파일
-p, --ssh-port PORT : SSH Port 이름
-C, --concurrency NUM : 동시 연결 수. 질의어에 따라서 여러 개의(심지어는 수백개) 노드가 검색될 수 있다. 이 옵션으로 동시 접속 가능한 ssh 수를 제한할 수 있다.
SSH_COMMAND : 실행할 ssh 명령

모든 node의 chef-client를 작동한다.

# knife ssh 'name:*' 'sudo chef-client'

Role이 변경됐을 때, 원격 node의 chef-client를 실행하기 위한 유일한 방법이다. 물론 corn에 등록하거나 chef-client -i옵션등을 이용해서 주기적으로 실행하는 방법이 있긴 하지만, 그다지 권할만한 방법은 아닌 것 같다. chef를 이용해서 시스템을 자동화할 경우 unix 계정도 함께 관리할 텐데, 이때 ssh-key를 함께 관리하도록 하자. 그러면 knife ssh와 ssh key를 이용해서, 원하는 시점에 chef-cliet를 실행할 수 있다.
