尝试迁移时 NpgsqlTimeout 超时
NpgsqlTimeout timeout when trying to migrate
我正在 .Net 5 中开发一个项目,使用的数据库是 Postgres。我正在使用 docker-compose 文件数据库,但是当我 运行 dotnet ef database update
命令时,出现以下错误:
Build started...
Build succeeded.
Npgsql.NpgsqlException (0x80004005): Exception while connecting
---> System.Net.Sockets.SocketException (111): Connection refused
at Npgsql.NpgsqlConnector.Connect(NpgsqlTimeout timeout)
....
Exception while connecting
Docker-撰写:
version: '3.1'
services:
db:
image: postgres
restart: always
environment:
POSTGRES_USER: Guilherme
POSTGRES_PASSWORD: XXXX
POSTGRES_DB: BuiltCode
pgadmin:
image: dpage/pgadmin4
restart: always
environment:
PGADMIN_DEFAULT_EMAIL: admin@admin.com
PGADMIN_DEFAULT_PASSWORD: root
ports:
- "5050:80"
连接字符串:
"PostgreSql": "Username=Guilherme;Password=XXXX;Server=localhost;Port=5432;Database=BuiltCode;"
有人可以帮我吗?
在 db
部分下添加:
ports:
- '5432:5432'
