Api not accessible once i changed the domain names in docker compose file

[virkse]

I just changed the domain names in docker-compose.yml file so api is not accessible. Also i didn't get information how to change the domain. Please help me.

My docker compose file, I just changed http://api to https://api-platform.local
Also i put the https://api-platform.local in /etc/hosts
When i run the logs from container using docker-compose logs -f the following message return.
http: proxy error: dial tcp: lookup api-platform.local on 127.0.0.11:53: no such host" symfony api platform

Hi,

From the doc :

When you run docker-compose up, the following happens:
1 - A network called myapp_default is created.
2 - A container is created using web’s configuration. It joins the network myapp_default under the name web.
3 - A container is created using db’s configuration. It joins the network myapp_default under the name db.

Each container can now look up the hostname web or db and get back the appropriate container’s IP address. For example, web’s application code could connect to the URL postgres://db:5432 and start using the Postgres database.

You are not supposed to edit http://api, this is the hostname used by your containers (vulcain and the client generator) to reach your container called "api" inside their network. You will use https://api-platform.local to reach vulcain and vulcain will use http://api to reach api.

To change the domain from /etc/hosts you need to

• map it to the IP of the machine hosting docker (localhost or a virtual machine IP or whatever but not your container) :

127.0.0.1 api-platform.local

• edit CORS_ALLOW_ORIGIN and TRUSTED_HOSTS in api/.env (or create api/.env.local)

TRUSTED_HOSTS='^(api-platform.local|localhost|api)$'
CORS_ALLOW_ORIGIN=^https?://(api-platform.local|localhost|127\.0\.0\.1)(:[0-9]+)?$

• edit REACT_APP_API_ENTRYPOINT in admin/.env and client/.env

REACT_APP_API_ENTRYPOINT=https://api-platform.local:8443

• edit mercure.PUBLISH_ALLOWED_ORIGINS from docker-compose.yml

PUBLISH_ALLOWED_ORIGINS=https://api-platform.local:1337

• Build and up using docker-compose.

Then you can go to https://api-platform.local:8443

@Ledalys It was really a life saving reply. I clears my understandings. Thank you very much to help me out.
