AWS Elastic Beanstalk에 배포할 때 awscli 및 awsebcli를 사용하고 있습니다. 되었습니다.
여러가지 시행착오한 결과 에러를 해결할 수 있었으므로(?) 그래서, GitHub Actions로 양 커멘드를 정상적으로 인스톨 할 수 있는 방법을 소개합니다.

발생한 오류

환경

ubuntu 18.04 on GitHub Actions

파이썬 3.7.5

awscli 1.16.*

awsebcli 3.15.*

오류 내용

awscli와 awsebcli 모두 pip를 사용하여 설치하는 동안 오류가 발생했습니다.

$ pip install awscli awsebcli

훌륭하게 의존성을 해결하지 못했습니다.
설치 후 두 명령을 실행했을 때의 로그가 ↓입니다.

PyYAML 버전이 충돌하고 있습니다.
Issue에 올라가도록 버전을 지정하거나 종속 패키지를 수동으로 설치해 보았지만 작동하지 않았습니다.
또한 pipenv를 사용하여 가상 환경에서 분리하여 설치해 보아도 좋지 않았습니다.

거기서 검증용의 리포지토리를 작성해 여러가지 패턴을 시험해 성공하는 것이 있는지 조사했습니다.

성공 패턴

여기 리포지토리에서 실험하여 성공한 패턴이 몇 가지 있었지만, 그 중에서도 개인적으로 베스트라고 생각하는 Workflow를 소개합니다.

환경

MacOS Catalina

Python 3.7.5

awscli 1.16.*

awsebcli 3.15.*

2019/11/6에 MacOS가 Catalina로 업데이트되었습니다
참고: GitHub Actions – macOS virtual environment updated to Catalina

GitHub Actions 예

awscli를 brew로, awsebcli를 pip로 설치합니다.

name: Install awscli and awsebcli on Mac

on: push

jobs:
 test:
    name: Install awscli and awsebcli
    runs-on: macos-latest
    steps:
      - uses: actions/checkout@master

      - name: Install awscli
        run: |
          brew update
          brew install awscli
          brew upgrade

      - uses: actions/setup-python@master
        with:
          python-version: '3.7'

      - name: Install awsebcli
        run: pip install -U awsebcli

      - name: Check version
        run: |
          aws --version
          eb --version

Check version 실행 로그

$ aws --version
aws-cli/1.16.260 Python/3.7.5 Darwin/19.0.0 botocore/1.12.250

$ eb --version
EB CLI 3.15.3 (Python 3.7.5)

이런 느낌의 성공적으로 설치할 수 있고, 제대로 명령을 실행할 수 있습니다.
그 밖에도 성공 패턴이 있었습니다만, 베이스가 되고 있는 Python의 버젼이 2계가 되어 버렸습니다.
그래서 ↑가 최고입니다

다양한 패턴은 여기 리포지토리에 있습니다. (갑자기 사라질지도 모르지만 용서를 ...)
