`An error occurred listing credentials` with `docker-credential-gcr`

[glebbash]

Expected Behaviour
Should work fine :)

Actual Behaviour
Having docker-credential-gcr installed makes it not possible to start testcontainers.

Problem is that running docker-credential-gcr list command returns exit code 1, which triggers an error here:

testcontainers-node/packages/testcontainers/src/container-runtime/auth/credential-provider.ts

Line 46 in 0488293

return reject(new Error("An error occurred listing credentials"));

This is caused by list command being not implemented:

Usage: docker-credential-gcr <flags> <subcommand> <subcommand args>
...
Subcommands for Docker credential store API:
        erase            (UNIMPLEMENTED) erase any stored credentials for the server specified via stdin
        get              for the server specified via stdin, return the stored credentials via stdout
        list             (UNIMPLEMENTED) list all stored credentials
...

P.S: not really sure what commands are required to be implemented by docker credential helpers spec (if there is one) so it might be an issue for docker-credential-gcr repo.

Steps to Reproduce

1. Install docker-credential-gcr
2. Run the following (or any other container):

import { GenericContainer, Wait } from "testcontainers";

const spannerEmulator = await new GenericContainer(
  "gcr.io/cloud-spanner-emulator/emulator"
)
  .withExposedPorts(9010)
  .withWaitStrategy(Wait.forLogMessage("gRPC server listening at"))
  .start();

If anyone has come to this page from a quick Google, the below fixed it for me:

In ~/.docker/config.json, remove the below entry, and save:

{
  //
  "credsStore": "desktop"
  //
}

@cristianrgreco can you get the linked PR merged pls? I tested that it works locally and added a unit test.

Mac OS X, Docker Desktop here. I didn't have docker-credential-gcr installed, but removing the credsStore line fixed the issue.

I had this issue running testcontainers locally on MacOS Sonoma 14.4, and just changing "credsStore": "desktop" to "credStore": "desktop" in my ~/.docker/config.json worked for me. Ref

I upgraded from 11.6.0 to 11.7.0 and the issue started to occur, both in CI and locally. Downgrading to 11.6.0 fixed the issue.

Edit: fixed by version 11.7.1.
