다른 브랜치를 사용하여 Heroku에 Django 배포

문제

내 Django News 프로젝트를 Heroku에 배포하려고 했습니다. 그러나 나는 그것을 배포할 수 없었습니다. 매번 실패했습니다. 빌드 실패를 제공합니다.

투쟁

나는 cookiecutter-django 지시를 따랐다:

$ heroku create --buildpack https://github.com/heroku/heroku-buildpack-python

$ heroku addons:create heroku-postgresql:hobby-dev
# On Windows use double quotes for the time zone, e.g.
# heroku pg:backups schedule --at "02:00 America/Los_Angeles" DATABASE_URL
$ heroku pg:backups schedule --at '02:00 America/Los_Angeles' DATABASE_URL
$ heroku pg:promote DATABASE_URL

$ heroku addons:create heroku-redis:hobby-dev

$ heroku addons:create mailgun:starter

$ heroku config:set PYTHONHASHSEED=random

$ heroku config:set WEB_CONCURRENCY=4

$ heroku config:set DJANGO_DEBUG=False
$ heroku config:set DJANGO_SETTINGS_MODULE=config.settings.production
$ heroku config:set DJANGO_SECRET_KEY="$(openssl rand -base64 64)"

# Generating a 32 character-long random string without any of the visually similar characters "IOl01":
$ heroku config:set DJANGO_ADMIN_URL="$(openssl rand -base64 4096 | tr -dc 'A-HJ-NP-Za-km-z2-9' | head -c 32)/"

# Set this to your Heroku app url, e.g. 'bionic-beaver-28392.herokuapp.com'
$ heroku config:set DJANGO_ALLOWED_HOSTS=

# Assign with AWS_ACCESS_KEY_ID
$ heroku config:set DJANGO_AWS_ACCESS_KEY_ID=

# Assign with AWS_SECRET_ACCESS_KEY
$ heroku config:set DJANGO_AWS_SECRET_ACCESS_KEY=

# Assign with AWS_STORAGE_BUCKET_NAME
$ heroku config:set DJANGO_AWS_STORAGE_BUCKET_NAME=

$ git push heroku master

$ heroku run python manage.py createsuperuser

$ heroku run python manage.py check --deploy

$ heroku open

push 단계, 37행까지 모든 것이 정상이었습니다. 이 행은 Build Failed 오류를 제공합니다. Heroku의 단락 출력은 다음과 같습니다.

 !     Push rejected, failed to compile Python app.
 !     Push failed

다음과 같은 오류 로그를 볼 수 있습니다. 변수DJANGO_GCP_STORAGE_BUCKET_NAME가 설정되지 않았습니다. 예, 설정하지 않아야 합니다.

프로젝트 초기에 저는 Google Cloud Platform을 "클라우드 공급자"로 선택했습니다. 그러나 단순하고 사용하기 쉽도록 정적 파일을 제공하기 위해 WhiteNoise으로 전환했습니다.

그러나 "생산 설정"에 설정된 variable를 이미 삭제했습니다.

# configs/settings/production.py
GS_BUCKET_NAME = env("DJANGO_GCP_STORAGE_BUCKET_NAME")

그렇다면 Heroku의 문제는 무엇입니까? 프로젝트의 이전 커밋을 사용하는 이유는 무엇입니까?

나는 해결책을 찾기 위해 거의 2시간 동안 고군분투했다.

해결책

해결책은 Heroku에 branch you push를 지정하는 것이 었습니다. 기본 명령입니다.

$ git push heroku master

master 분기를 배포의 master 분기로 푸시합니다. 그러나 나는 master 가 아니라 heroku 분기에 있습니다. 이 분기는 수십 개의 커밋이 있는 현재 분기입니다.

doc Deploying from a branch besides master:Heroku 에서 언급했듯이 푸시하도록 분기를 변경했습니다.

$ git push heroku heroku:master

그리고 이제 성공이었습니다. 고통이 풀렸습니다.

모두 완료되었습니다!
