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.

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"
  //
}
