۴ – راه اندازی دیتابیس PostgreSQL و اتصال به پروژه جنگو

سلام استاد من وقتی docker-compose up -d رو میزنم این ارور رو میده بهم :

Creating msblog_postgresql … error

ERROR: for msblog_postgresql Cannot start service msblog_postgresql: Ports are not available: unable to list exposed ports: Get http://unix/forwards/list: open \\.\pipe\dockerBackendApiServer: The system cannot find the file specified.

ERROR: for msblog_postgresql Cannot start service msblog_postgresql: Ports are not available: unable to list exposed ports: Get http://unix/forwards/list: open \\.\pipe\dockerBackendApiServer: The system cannot find the file specified.
ERROR: Encountered errors while bringing up the project.

و وقتی که پروژه جنگو رو ران میکنم هم این ارور رو میگیرم :

could not connect to server: Connection refused (0x0000274D/10061)
Is the server running on host “localhost” (127.0.0.1) and accepting
TCP/IP connections on port 5432?

مشکل این ارور ها چیه؟؟

سلام وقت بخیر
دقیقا طبق آموزش های توسعه سریع وب با جانگو 2 فایل های docker-compose.yml و .env رو ایجاد کردم و کانتینر بدون مشکل استارت میشه اما وقتی می خوام دستور زیر رو اجرا کنم بهم ارور میده
docker exec -it blogpy_postgresql psql -U postgres -W postgres
متن ارور:
psql: error: could not connect to server: FATAL: role “postgres” does not exist
نام دیتابیس، نام کاربری و پسورد کاملا درسته.

سلام
اقای باباززاده من همه مراحل رو اجرا کردم در اخر وقتی run رو زدم
این پیامها رو نمایش داد http://uupload.ir/files/v1ut_capture.jpg

اینم بگم که من توی این قسمت اموزشتون ارور زیاد داشتم و برای رفع این کارها رو کردم:
1- داکر رو switch to windows containers کردم
2-در تنظیمات داکر experimental”: true” قرار دادم

سلام وقتتون بخیر استاد عذر میخوام من دستور docker-compose up -d رو میزنم ارر Can’t find a suitable configuration file in this directory or any parent. Are you in the right directory? Supported filenames: docker-compose.yml, docker-compose.yaml اینرو میده.فک کنم ادرس دایرکتوری ر. نمیتونه پیدا کن.در ویندوز نصب کردم ادرس خود فایل yml رو که در پوشه پروزه جنگو هست رو بهش دادم

سلام من موقع اجرای کامند docker exec -it blogpy_postgresql psql -U postgres -W postgres به اینم ارور برخوردم که
psql: error: could not connect to server: FATAL: role “postgres” does not exist
واینکه داخل ویندوز کار میکنم و postgres نصب نیست از قبل
تو کامنت ها دیدم همین سوال رو پرسیده بودن اما متوجه نشدم چجوری رفع کنم این ارور رو

سلام وقت بخیر

موقع اجرای دستور docker-compose up -d با خطای زیر مواجه میشم

ERROR: Named volume “aghilpadash_postgresql:/var/lib/postgresql/data:rw” is used in service “aghilpadash_postgre

sql” but no declaration was found in the volumes section.

راه حل هم تقریبا پیدا نکردم

نمیدونم چه کار باید کرد ؟

ممنون میشم راهنمایی کنید

با سلام من وقتی دستور داکر کامپوز آپ را میزنم این ارور را میده و خیلی سعی کردم رف مشکل کنم که نشد در محیط لینوکس هم کار میکنم.The Compose file ‘./docker-compose.yml’ is invalid because:
Invalid top-level property “network”. Valid top-level sections for this Compose file are: version, volumes, configs, services, networks, secrets, and extensions starting with “x-“.

You might be seeing this error because you’re using the wrong Compose file version. Either specify a supported version (e.g “2.2” or “3.3”) and place your service definitions under the services key, or omit the version key and place your service definitions at the root of the file to use version 1.
For more on the Compose file format versions, see https://docs.docker.com/compose/compose-file/

سلام اقای بابازاده
بنده چندین مشکل دارم
1- دیروز من وقتی در اوبنتو از python3 manage.py runserver نتیجه میداد و سرور ران میشد اما امروز که امتحان میکنم با چنین متونی مواجه میشم $ python manage.py runserver

علتش این دو تا چیه

یه انتقادی هم دارم به روند تدریس و دوره
اینکه برخی اصطلاحات و موضوعات باز نمیشه و بیان برخی دستورات کمی گنگه و به صورت خوب باز میشه تا برای مخاطب جا بیافته
در مجموع دوره مفیدیه
ممنون میشم بابت این دو مشکل کمکم کنید
