Introduction¶

Sometimes you might want to connect Hasura running in Docker with APIs (e.g. auth webhooks, event triggers, remote schemas) that are either running outside of Docker or in a different Docker container. Depending on the setting, the network config is different. This section shows how to connect in each of these use cases.

Network config¶

Connection	Config	Comment
Hasura to API (outside Docker)	With `--net=host`, `localhost:3000` Otherwise, `<docker-bridge-ip>:3000`, e.g. `172.17.0.1:3000`	Assuming the API is running on port `3000` The Docker bridge IP can be found via `ifconfig`
API (outside Docker) to Hasura	`localhost:8080`	Hasura runs on port `8080` by default
Hasura to API (both in docker-compose)	service name, e.g.: `api:3000`	Assuming the API is running on port `3000`
API to Hasura (both in docker-compose)	service name, e.g.: `hasura:8080`	Hasura runs on port `8080` by default
Hasura to API (both running with separate docker run)	Docker internal IP address	Can be obtained with `docker inspect`
API to Hasura (both running with separate docker run)	Docker internal IP address	Can be obtained with `docker inspect`

Connection	Config	Comment
Hasura to API (outside Docker)	`host.docker.internal:3000`	Assuming the API is running on port `3000`
API (outside Docker) to Hasura	`localhost:8080`	Hasura runs on port `8080` by default
Hasura to API (both in docker-compose)	service name, e.g.: `api:3000`	Assuming the API is running on port `3000`
API to Hasura (both in docker-compose)	service name, e.g.: `hasura:8080`	Hasura runs on port `8080` by default
Hasura to API (both running with separate docker run)	Docker internal IP address	Can be obtained with `docker inspect`
API to Hasura (both running with separate docker run)	Docker internal IP address	Can be obtained with `docker inspect`

Connection	Config	Comment
Hasura to API (outside Docker)	`docker.for.win.localhost:3000`	Assuming the API is running on port `3000`
API (outside Docker) to Hasura	`localhost:8080`	Hasura runs on port `8080` by default
Hasura to API (both in docker-compose)	service name, e.g.: `api:3000`	Assuming the API is running on port `3000`
API to Hasura (both in docker-compose)	service name, e.g.: `hasura:8080`	Hasura runs on port `8080` by default
Hasura to API (both running with separate docker run)	Docker internal IP address	Can be obtained with `docker inspect`
API to Hasura (both running with separate docker run)	Docker internal IP address	Can be obtained with `docker inspect`
