はじめに

docker-compose exec <service-name> python manage.py makemigrations

makemigrations

execの後に<container-name>または<container-id>を入力して実行する
docker exec <container-name-or-id> python manage.py makemigrations
実行例
コンテナ名が【test-python-web-1】の場合
docker exec test-python-web-1 python manage.py makemigrations
コンテナIDが【123456de2~】の場合
docker exec 123456de2 python manage.py makemigrations

migrations

execの後に<container-name>または<container-id>を入力して実行する
docker exec <container-name-or-id> python manage.py migrate
実行例
コンテナ名が【test-python-web-1】の場合
docker exec test-python-web-1 python manage.py migrate
コンテナIDが【123456de2~】の場合
docker exec 123456de2 python manage.py migrate
