Я хотел бы настроить nextcloud локально с помощью postgres через докер. Я могу сделать это, не пытаясь использовать postgres (т. е. с sqllite по умолчанию), но у меня возникают проблемы при использовании докера postgres в сочетании с образом nc.
Мой ноутбук Ubuntu 18.04.
Цель: я хотел бы иметь локально настроенный контейнер, который я мог бы легко (или, по крайней мере, несколько легко) переместить к облачному провайдеру, когда захочу. Я настраиваю тома для postgres, а также для nc, чтобы я мог перенести все на удаленный компьютер, как когда захочу.
Вот мой репозиторий, который включает Dockerfile и docker-compose:
Dockerfile: (Обратите внимание, что я добавляю smbclient, так как на собственном горьком опыте узнал, что мне это нужно для установки приложения для внешнего хранилища, которое я хотел бы использовать)
FROM nextcloud:production-apache
RUN apt-get update && apt-get install -y \
smbclient
Мой файл docker-compose:
version: "3.5"
services:
nextcloud:
build:
context: .
dockerfile: ./Dockerfile
ports:
- "8080:80"
volumes:
- $PROJECTS_DIR/Personal/mc1/nextcloud:/var/www/html
- $PROJECTS_DIR/Personal/mc1/apps:/var/www/html/custom_apps
- $PROJECTS_DIR/Personal/mc1/config:/var/www/html/config
- $PROJECTS_DIR/Personal/mc1/data:/var/www/html/data
environment:
- POSTGRES_HOST=nextcloud_db_1 # service name for postgres as assigned by Docker
- POSTGRES_DB=nextcloud_db
- POSTGRES_USER=postgres # will access postgres over 5432
- POSTGRES_PASSWORD=testing123
depends_on:
- db
db:
image: postgres
restart: always
volumes:
- ./postgres-data:/var/lib/postgresql/data
environment:
- POSTGRES_DB=nextcloud_db
- POSTGRES_USER=postgres
- POSTGRES_PASSWORD=testing123
Я не был очень уверен, как это настроить, и позаимствовал из другого сообщения здесь.
Исход:
С терминалом в репо:
docker-compose build
docker-compose up -d
Затем я могу получить доступ к nc по адресу http://localhost:8080/index.php, где я выбираю «postgres» и ввожу данные postgres из моего docker-compose: 
После ввода всех данных на скриншоте выше, когда я нажимаю «Завершить настройку», я получаю этот экран с ошибкой: 
Я искал файл с именем «журнал» в любом месте томов и нашел data/nextcloud.log. Вот что он показывает:

Звук у меня настроен или это баг? Я не уверен в своем добавлении postgres в docker-compose или правильно ли я это сделал?
Как я могу настроить nextcloud локально с postgres, используя докер и тома, чтобы я мог перенести всю свою настройку nextcloud от облачного провайдера к облачному провайдеру по своему выбору?
