当我添加新命令来撰写时，Docker Compose出现Django错误

Question

Docker compose无法识别echo命令。

最近我添加了命令：

echo "from django.contrib.auth.models import User; User.objects.create_superuser('admin', 'admin@example.com', '2222bbbb')" | python manage.py shell

撰写代码：

version: '2'

services:
    postgres:
        image: postgres
        container_name: app_postgres
        environment:
            - POSTGRES_DB=postgres
            - POSTGRES_USER=postgres
            - POSTGRES_PASSWORD=postgres

    django:
        image: python:3.6.8
        container_name: app_django
        environment:
            - DJANGO_SETTINGS_MODULE=project.settings_staging
            - POSTGRES_DB=postgres
            - POSTGRES_USER=postgres
            - POSTGRES_PASSWORD=postgres
            - POSTGRES_HOST=postgres
        working_dir: /code
        volumes:
            - ./:/code
            - ./requirements.txt:/code/requirements.txt
        ports:
            - 6000:8000
        command: bash -c "pip install -r requirements.txt && python manage.py migrate --noinput && echo "from django.contrib.auth.models import User; User.objects.create_superuser('admin', 'admin@example.com', '2222bbbb')" | python manage.py shell && python manage.py test"
        depends_on:
            - postgres

当我执行此撰写时，Django完成下一条消息：

app_django |   Apply all migrations: account, admin, auth, authtoken, contenttypes, filters, sessions, sites, users
app_django | Running migrations:
app_django |   No migrations to apply.
app_django | from
app_django exited with code 0

Django无法识别echo命令

Answer 1

您没有在命令中使用双引号，因为您使用了两次。 第二次使用双引号时，应将其转义，否则，它将只是前一个引号的结尾。

command: bash -c "pip install -r requirements.txt && python manage.py migrate --noinput && echo \"from django.contrib.auth.models import User; User.objects.create_superuser('admin', 'admin@example.com', '2222bbbb')\" | python manage.py shell && python manage.py test"
