无法配置Testcontainers Docker：拉取ryuk镜像失败求助

我们的集成测试需要用到docker.io/testcontainers/ryuk镜像，但执行命令go test ./... --tags=integration -v时，反复出现以下错误：

=== RUN   TestLambda
2023/06/15 17:14:21 github.com/testcontainers/testcontainers-go - Connected to docker:

2023/06/15 17:14:25 Failed to pull image: Error response from daemon: Please run 'docker login', will retry

我已完成Docker登录，能正常拉取Redis等其他镜像，请问遗漏了什么配置？

运行测试代码后，仍出现相同错误，输出如下：

go test ./... --tags=integration -v

我的Docker配置文件内容：

{
        "auths": {
                "https://index.docker.io/v1/": {}
        },
        "credsStore": "desktop",
        "currentContext": "desktop-linux"
}

解决方案 #

• 升级testcontainers-go版本：旧版本对Docker Desktop的credsStore: desktop支持存在缺陷，升级到最新稳定版即可解决。执行命令：

  go get github.com/testcontainers/testcontainers-go@latest
  

• 调整Docker凭证存储配置：临时修改~/.docker/config.json，将"credsStore": "desktop"替换为对应系统的凭证存储（Mac用osxkeychain，Windows用wincred），或直接注释该行（注意：注释后凭证会明文存储，存在安全风险）。

• 手动拉取ryuk镜像：先手动执行拉取命令，确保本地已有镜像后再运行测试：

  docker pull docker.io/testcontainers/ryuk:0.4.0
  

• 禁用ryuk镜像的凭证检查：通过环境变量跳过凭证验证，直接运行测试：

  TESTCONTAINERS_RYUK_DISABLE_AUTH=true go test ./... --tags=integration -v
