Postgres Test Containers stopped working on GitHub Actions

Question

I'm using the Postgres Test Container module for writing DB integration tests for an API in Go. Also, I'm using GitHub Actions as part of CI to run these tests.

Test code:

        pgContainer, err := postgres.RunContainer(ctx,
            testcontainers.WithImage("postgres:14-alpine"),
            postgres.WithDatabase("db"),
            postgres.WithUsername("user"),
            postgres.WithPassword("secret"),
            testcontainers.WithWaitStrategy(
                wait.ForLog("database system is ready to accept connections").
                    WithOccurrence(2).WithStartupTimeout(5*time.Second)),
        )
        if err != nil {
            t.Fatal(err)
        }
        ...
        // get a connection pool for the above container via the connection string.
        // use the connection pool in the tests.
         

The setup used to work fine for about a week. I was quite happy with the results, and smug about putting it all together.

That is, until this morning when the CI started failing out of the blue. Now, all I have are the following errors:

Any clues on what could have caused this and/or suggestions on how to go about debugging this.

Please note: The same tests still work locally on my macOSX machine. They just fail on GitHub Actions runner.

This issue seems to be related to the Go version 1.20.6 release.

Pinning the Go version to 1.20.5 in the tests circumvented the issue so far.

Here is a link to GitHub issue that reports similar behavior: https://github.com/moby/moby/issues/45935
