Missing PostgreSQL driver import in Go tutorial

[kazuyainoue0124]

Is this a docs issue?

• My issue is about the documentation content or website

Type of issue

Information is incorrect

Description

In the Use containers for Go development tutorial, the code sample omits the explicit import for the PostgreSQL driver. Without:

import _ "github.com/lib/pq"

sql.Open("postgres", ...) fails with sql: unknown driver "postgres" (forgotten import?), causing the container to never listen on the port. This leads to curl: (52) Empty reply from server and no helpful logs unless the user explicitly adds logging in the retry loop.

Location

https://docs.docker.com/guides/golang/develop/

Suggestion

Either

1. Add import _ "github.com/lib/pq" in the example code, or
2. Clearly document that _ "github.com/lib/pq" must be used when connecting to PostgreSQL or CockroachDB.

Thank you for your work on the docs.

I stepped through the tutorial but I'm not seeing that issue. What am I missing?
