  * [[https://github.com/awsdocs/elastic-beanstalk-samples|awsdocs/elastic-beanstalk-samples: This repository contains code and configuration samples (e.g. .ebextensions) for AWS Elastic Beanstalk.]]

===== Custom Platform =====
  * [[https://docs.aws.amazon.com/ko_kr/elasticbeanstalk/latest/dg/custom-platforms.html|사용자 지정 플랫폼 - AWS Elastic Beanstalk]]

===== Java Process =====
  * [[https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/java-se-procfile.html|Configuring the Application Process with a Procfile - AWS Elastic Beanstalk]]
  * Log 파일 경로는 ''process이름-1.log'', ''process이름-1.error.log'' : Standard output and error streams from processes started with a Procfile are captured in log files named after the process and stored in /var/log. For example, the web process in the preceding example generates logs named web-1.log and web-1.error.log for stdout and stderr, respectively.

===== ebextensions =====

==== 특정 패키지 설치 ====
  * yum, rubygems, python 및 rpm 등의 패키지 관리자를 지원합니다. 패키지는 rpm, yum, rubygems 및 python의 순서대로 처리됩니다. rubygems와 python 간에는 순서가 없습니다. 각 패키지 관리자에서 패키지 설치 순서는 보장되지 않습니다.

<code>
packages: 
  yum:
    libmemcached: [] 
    ruby-devel: []
    gcc: []
  rpm:
    epel: http://download.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm
  rubygems: 
    chef: '0.10.2'
</code>


==== 조건적 명령 실행 ====
  * ''test: 테스트 shell script'' 사용. 결과가 ''true''(즉, ''0'')일때 command 실행. [[linux:test|test]]
  * [[https://stackoverflow.com/a/27409532/1051402|How to use conditional in .ebextensions config (AWS Elastic Beanstalk)]]

<code>
commands:
  01_create_dir:
    test: test ! -d "${DIR}"
    command: mkdir "${DIR}"
    
# 아래와 같은 식도 가능
    test: "[ -x /usr/bin/python ]" # 파이썬이 존재하면 실행
</code>
  * ''rpm -q wget'' : ''wget'' 패키지가 설치돼 있으면 ''true/0''
==== leader_only ====
  * 특정 EBT 환경에 설정한 특정 단일 인스턴스에서만 명령 실행
  * ''test:''와 함께 사용 불가

<code>
container_commands:
  collectstatic:
    command: "django-admin.py collectstatic --noinput"
  01syncdb:
    command: "django-admin.py syncdb --noinput"
    leader_only: true
</code>
