Docker 1.12: Now with Built-in Orchestration! 테스트
13702 단어 Docker
[참고 번역] Docker 1.12: 드디어 공개 퍼포먼스에 합류했습니다!Pocketstudio Technology Log
[익스프레스] Docker는 최신 버전의 Docker Engine에 공개 기능을 내장했습니다.외부 도구가 필요 없이 집단 운용을 실현하다.DockerCon 16 － Publickey
Docker만 공개 공연을 할 수 있다고 합니다.
한 번 시험해 보았다
Version
맥으로 이동하는 Docker 호스트로 하고 싶어요.
$ docker node ls
ID NAME MEMBERSHIP STATUS AVAILABILITY MANAGER STATUS
5cqlhnd928r9pbklk3n7r9nb2 * moby Accepted Ready Active Leader
$
$ docker-machine ip moby
Host does not exist: "moby"
$
(아무래도 Mac는 DHCP가 설정한 것이기 때문에 swarm에서 합작하기에 적합하지 않다)
다중 구성 시도
VirtualBox에서 docker machine 만들기
$ docker-machine create swarm-manager01 --driver virtualbox
$ docker-machine create swarm-manager02 --driver virtualbox
$ docker-machine create swarm-manager03 --driver virtualbox
$ docker-machine create swarm-worker01 --driver virtualbox
$ docker-machine create swarm-worker02 --driver virtualbox
$ docker-machine create swarm-worker03 --driver virtualbox
호스트 정보 확인
$ docker-machine ls

Manager 구성
swarm-manager01에서 init
$ eval $(docker-machine env swarm-manager01)
$ docker swarm init --listen-addr 192.168.99.103:2377
$ #自動でjoinしないようにしたい場合は --auto-accept none とか付ける
$ eval $(docker-machine env swarm-manager02)
$ docker swarm join --manager --listen-addr 192.168.99.104:2377 192.168.99.103:2377
This node joined a Swarm as a manager.
$
$ eval $(docker-machine env swarm-manager03)
$ docker swarm join --manager --listen-addr 192.168.99.105:2377 192.168.99.103:2377
This node joined a Swarm as a manager.
$
Worker 구성
join 명령에 관리자 옵션을 추가하지 않으면worker
swarm-worker01의 join
$ eval $(docker-machine env swarm-worker01)
$ docker swarm join --listen-addr 192.168.99.106:2377 192.168.99.103:2377
This node joined a Swarm as a worker.
$
$ eval $(docker-machine env swarm-worker02)
$ docker swarm join --listen-addr 192.168.99.107:2377 192.168.99.103:2377
This node joined a Swarm as a worker.
$
$ eval $(docker-machine env swarm-worker03)
$ docker swarm join --listen-addr 192.168.99.108:2377 192.168.99.103:2377
This node joined a Swarm as a worker.

Nginx를 시작해 보십시오.
Manager node 작업
$ eval $(docker-machine env swarm-manager01)
$ docker service create --name frontend --replicas 5 -p 80:80/tcp nginx:latest

워크맨의 IP도 연결됩니다.균형이 잡혔어요.
(반응이 좋지 않습니다. 시간이 필요합니다. VM이 너무 많이 늘었습니까?)

워커가 멈추면 어떻게 돼요?
빨리 Orchest tration 해줘!
kill swarm-worker03
$ docker-machine kill swarm-worker03
2초 뒤쯤?
(1Mac에 있으니까)
