디스코urs Docker 설치 환경에서 DB를 마이그레이션하려고 하면 계속 이 Redis 오류가 발생합니다. 도움을 부탁드립니다.
2컨테이너 설치 환경이거나 Redis가 다른 곳에 호스팅되어 있나요? Redis 6.2를 사용하고 있나요?
제 Redis 버전은 6.2.6이며, Docker에는 Redis 컨테이너 하나와 discourse_dev 컨테이너 몇 개만 실행 중입니다.
Sidekiq GitHub에서도 도움을 요청했습니다.
Docker 컨테이너에서 다음을 실행하면 이런 결과가 나옵니다.
d/bundle show redis
/Users/natashaselvidge/discourse/vendor/bundle/ruby/2.6.0/gems/redis-4.6.0
제 discourse_redis.rb 파일은 다음과 같습니다.

개발 환경에서 Redis gem을 4.5.1에서 4.6.0으로 수동으로 업데이트한 것으로 보입니다. Discourse는 해당 gem 버전과 호환되지 않으므로, Gemfile.lock 파일에서 사용하는 버전으로 되돌려야 합니다.
redis-rb 4.6.0으로의 전환을 진행 중이지만, 이는 상당한 작업이 필요합니다:
아, 알겠어요! 정말 감사합니다! 해볼게요 
업데이트
앞으로 이 정보가 필요한 분들을 위해 공유합니다 
그렇게 하니 문제가 해결되었습니다! 감사드립니다. 제 discourse를 업데이트했지만, gem 파일에 버전이 명시되어 있지 않았습니다. 다음과 같이 끝에 버전 번호를 추가했습니다: gem ‘redis’, “~> 4.5.1”
Gemfile.lock에서 이를 지정합니다:
제가 Gemfile.lock을 삭제하고 bundle을 실행했기 때문이라고 생각합니다. 그 후 GitHub에서 Redis와 Sidekiq 관련 이슈 담당자들과 이야기를 나누었는데, 업데이트된 버전을 사용해야 한다고 알려주었습니다. 다시 한번 감사합니다!
