I am running NetCore project with docker support. My docker-compose.override.yml:
version: '3.4'
services:
traefik:
ports:
- '80:80'
- '443:443'
- '8080:8080'
myapi:
environment:
- 'ASPNETCORE_ENVIRONMENT=Development'
- 'ConnectionStrings:DbConnection=postgresql://postgres'
- 'Services:Authorization=http://10.0.75.1'
- 'Authorization:Url=http://10.0.75.1'
postgres:
environment:
POSTGRES_USER: "user"
POSTGRES_PASSWORD: "pass"
POSTGRES_DB: testdb
ports:
- 5432:5432
pgadmin4:
environment:
- PGADMIN_DEFAULT_EMAIL=user@domain.com
- PGADMIN_DEFAULT_PASSWORD=SuperSecret
ports:
- 19000:80
And docker-compose.yml:
version: '3.4'
services:
traefik:
image: traefik
command: --web --docker --docker.domain=docker --logLevel=DEBUG
volumes:
- /var/run/docker.sock:/var/run/docker.sock
- /develop/traefik/acme:/etc/traefik/acme
postgres:
image: postgres
labels: { "traefik.enable":"false" }
myapi:
image: myapi
build:
context: .
dockerfile: MyApi/Dockerfile
links:
- postgres
labels: { "traefik.backend":"myapi", "traefik.frontend.rule":"PathPrefixStrip:/" }
pgadmin4:
image: dpage/pgadmin4
links:
- postgres
I can't bind connection string from myapi service to postgres docker container. I have also tried with postgresql://postgres:postgres@db:5432, and postgresql://, and just postgres, no luck.
I am getting log:
System.ArgumentException: Format of the initialization string does not conform to specification starting at index 0.
So obviously i cannot reach the db server.
My original connection string, when I run app locally, works great, in form:
User ID = user;Password=pass;Server=localhost;Port=5432;Database=testdb;Integrated Security=true;Pooling=true
Any ideas how to map my service with postgres in docker here? Thx!
I think you should use this:
User ID = user;Password=pass;Server=postgres;Port=5432;Database=testdb;Integrated Security=true;Pooling=true
