+
+<SubHeading>Learn how to access host servcies from a docker container.</SubHeading>
+
+Sometimes, having a Dockerized project, we might need to access local sevices like Redis, MySql or PostgreSQL. 
+This use case is supported by Docker when we set in the environment the **hostname** to **host.docker.internal** instead of using the traditional `localhost` or `127.0.0.1` witch might lead to runtime errors like this:
+
+`connection to server at "localhost" (::1), port 5432 failed: Cannot assign requested address` 
+
+<br />
+
+> Some well-known local services we can access from a **Docker Container** 
+
+- **Redis**: port `6379`, hostname **host.docker.internal**, instead of `localhost`
+- **MySql**: port `3306`, hostname **host.docker.internal**, instead of `localhost`
+- **Postgresql**: port `5432`, hostname **host.docker.internal**, instead of `localhost`
