1. 사전조건
fly를 사용할 수 있어야 하고 PATH에 걸려있어야 함.
wget https://github.com/concourse/concourse/releases/download/v5.6.0/fly-5.6.0-linux-amd64.tgz
2. 로그인 설정
2.1. ID/PW 방식
$ fly --target helloworld login --concourse-url http://127.0.0.1:8080 -u test -p test logging in to team 'main' target saved
로그인 설정을 하고 나면 홈 디렉토리에 flyrc라는 파일이 생성(혹은 내용 추가)된다.
$ cat ~/.flyrc
targets:
helloworld:
api: http://127.0.0.1:8080
team: main
token:
type: Bearer
value: abcd..
2.2. Token 방식
$ fly -t mytest login -c http://127.0.0.1:8080 logging in to team 'main' navigate to the following URL in your browser: http://127.0.0.1:8080/login?fly_port=43985 or enter token manually:
그리고 위에서 말한대로 http://127.0.0.1:8080/login?fly_port=43985 (IP 주소는 실제 접속 주소로 수정 필요) 에서 Token 값 얻어서 붙여넣으면 2.1과 동일하게 target 생성된다.
or enter token manually: Bearer eyJhbGciOiJSUzI1NiIsImtpZCI6IiIsInR5cCI6IkpXVCJ9.eyJjc3JmIjoiZWMxOGZiOTU0ZmNhZmJhZjY4YjEwYjQ2YTMyYTZlZDQxMGVlNDJkMmNmYmU5M2M1ZTI5ZTMyNzk2NDEyZTU5ZCIsImVtYWlsIjoidGVzdCIsImV4cCI6MTU3MjU3NTQ2NiwiaXNfYWRtaW4iOnRydWUsIm5hbWUiOiIiLCJzdWIiOiJDZ1IwWlhOMEVnVnNiMk5oYkEiLCJ0ZWFtcyI6eyJtYWluIjpbIm93bmVyIl19LCJ1c2VyX2lkIjoidGVzdCIsInVzZXJfbmFtZSI6InRlc3QifQ.EhDOe7CYo5rU_tRpnxDvipDr3QsBEKbiqv_phvCcwvb8XYEIbFWY6Dfj19X1kf3fezp-Lz1Y-OtW9Ang9x7PhAMhFd3ZJf5NbVQolezGU9Kl87OqbprmXyxs1bra5vEtO0djpzQDKynBmYejxh3EpCgrtLgDncwMoPPvRIdYwgLG681n1nKL9H_tiI_f9Qc43r6TcHoMXurIG2dnhmH4umamOpBqS3LImWeamuumR3676jSHuwFyY_V1g_Ho4U0fZww1ql3qAeReXeT-i4b1EFQT0iSxuRw3qJkGsUeVpDdd-SsZQiXSz_pH6K-sVcS9_T8QuESjV56q13LTsW_6zQ target saved
3. Task 실행
두가지 종류의 Task를 만들어보려고 한다.
- hello world를 찍는 Task
- ps -ef 결과를 보여주는 Task
3.1. Hello World
다음 파일을 task-hello-world.yml 이라고 하자.
---
platform: linux
image_resource:
type: docker-image
source: {repository: busybox}
run:
path: echo
args: [hello world]
Task를 실행한다.
$ fly -t helloworld execute -c task-hello-world.yml uploading helloworld done executing build 1 at http://127.0.0.1:8080/builds/1 initializing waiting for docker to come up... Pulling busybox@sha256:dd97a3fe6d721c5cf03abac0f50e2848dc583f7c4e41bf39102ceb42edfd1808... sha256:dd97a3fe6d721c5cf03abac0f50e2848dc583f7c4e41bf39102ceb42edfd1808: Pulling from library/busybox 7c9d20b9b6cd: Pulling fs layer 7c9d20b9b6cd: Download complete 7c9d20b9b6cd: Pull complete Digest: sha256:dd97a3fe6d721c5cf03abac0f50e2848dc583f7c4e41bf39102ceb42edfd1808 Status: Downloaded newer image for busybox@sha256:dd97a3fe6d721c5cf03abac0f50e2848dc583f7c4e41bf39102ceb42edfd1808 Successfully pulled busybox@sha256:dd97a3fe6d721c5cf03abac0f50e2848dc583f7c4e41bf39102ceb42edfd1808. running echo hello world hello world
Concourse 화면의 /builds/1로도 확인 가능하다.
3.2. ps -ef Task
다음은 task-ps-ef.yml 이다.
$ cat task-ps-ef.yml
---
platform: linux
image_resource:
type: docker-image
source: {repository: ubuntu}
run:
path: ps
args: [-ef]
Task를 실행한다.
$ fly -t helloworld execute -c task-ps-ef.yml uploading helloworld done executing build 3 at http://127.0.0.1:8080/builds/3 initializing running ps -ef UID PID PPID C STIME TTY TIME CMD root 1 0 0 07:31 ? 00:00:00 /tmp/garden-init root 6 0 0 07:31 pts/0 00:00:00 ps -ef succeeded
4. Jobs (Input/Output)
4.1. Helloworld
helloworld.yml
---
jobs:
- name: test
plan:
- task: simple-task
params:
message: Hello World
config:
platform: linux
params:
message:
image_resource:
type: registry-image
source: {repository: busybox}
run:
path: sh
args:
- "-c"
- |
echo $message
Pipeline을 생성한다.
$ fly -t mytest set-pipeline -p helloworld -c ./helloworld.yml
jobs:
job test has been added:
+ name: test
+ plan:
+ - config:
+ container_limits: {}
+ image_resource:

+ run:
+ args:
+ - -c
+ - |
+ echo $message
+ path: sh
+ params:
+ message: Hello World
+ task: simple-task
apply configuration? [yN]: y
pipeline created!
you can view your pipeline here: http://127.0.0.1:8080/teams/main/pipelines/helloworld
the pipeline is currently paused. to unpause, either:
- run the unpause-pipeline command:
fly -t mytest unpause-pipeline -p helloworld
- click play next to the pipeline in the web ui
실행결과다.

4.2. create-and-consume
파일을 보내는 실습이다.
다음 파일을 jobs-create-and-consume.yml 이라고 하자.
---
jobs:
- name: create-and-consume
public: true
plan:
- task: make-a-file
config:
platform: linux
image_resource:
type: registry-image
source: { repository: busybox }
run:
path: sh
args:
- -exc
- ls -la; echo "Created a file on $(date)" > ./files/created_file
outputs:
- name: files
- task: consume-the-file
config:
platform: linux
image_resource:
type: registry-image
source: { repository: busybox }
inputs:
- name: files
run:
path: cat
args:
- ./files/created_file
fly 명령어를 실행한다. 앞 실습과 달리 set-pipeline을 사용한다.
$ fly -t helloworld set-pipeline -c jobs-create-and-consume.yml -p create-and-consume
jobs:
job create-and-consume has been added:
+ name: create-and-consume

- click play next to the pipeline in the web ui
위에서 알려준대로 Concourse UI에 들어가보자.
그리고 다음과 같이 실행되었다.
4.3. ps-ef-input
ps -ef 정보를 보내는 실습이다.
다음 파일을 jobs-ps-ef-input.yml 이라고 하자.
---
jobs:
- name: ps-ef-input
public: true
plan:
- task: make-a-file
config:
platform: linux
image_resource:
type: registry-image
source: { repository: ubuntu }
run:
path: sh
args:
- -exc
- ps -ef > ./files/result_ps_ef_input
outputs:
- name: files
- task: consume-the-file
config:
platform: linux
image_resource:
type: registry-image
source: { repository: ubuntu }
inputs:
- name: files
run:
path: cat
args:
- ./files/result_ps_ef_input
fly -t helloworld set-pipeline -c jobs-ps-ef-input.yml -p ps-ef-input 을 실행하여 파이프라인을 생성한다.
