podman：错误：无法解析“X-Registry-Auth”标头

Question

我第一次尝试使用podman（在Mac OS 下使用podman machine，但这可能无关紧要）。当我尝试启动busybox图像作为测试时，like described in Introduction:

podman run -it docker.io/library/busybox

我收到以下错误：

Error: failed to parse "X-Registry-Auth" header for /v3.3.1/libpod/images/pull?alltags=false&arch=&authfile=&os=&password=&policy=missing&quiet=false&reference=docker.io%2Flibrary%2Fbusybox&username=&variant=: error storing credentials in temporary auth file (server: "https://index.docker.io/v1/", user: ""): key https://index.docker.io/v1/ contains http[s]:// prefix

（podman 版本 3.3.1）

Answer 1

原因是我有 Docker Desktop 创建的 ~/.docker/config.json 文件。它有 docker.io 注册表的空条目，没有凭据，这是导致此错误的原因。

由于该文件没有有价值的配置（主要是默认值），我将其删除，问题不再发生。

% podman run -it docker.io/library/busybox

编辑~/.docker/config.json 文件并删除https://

之前的配置（不工作）

{
{
  "credsStore" : "desktop",
  "auths" : {
    "https://index.docker.io/v1/" : {

    },
    "xxx-yyy-docker.artifactory.zzzz.com" : {

    },
    "registry.gitlab.zzzz.com" : {

    }
  },
  "credHelpers" : {
    "gcr.io" : "gcloud",
    "europe-west1-docker.pkg.dev" : "gcloud"
  }
}

之后（工作正常）

{
{
  "credsStore" : "desktop",
  "auths" : {
    "index.docker.io/v1/" : {

    },
    "xxx-yyy-docker.artifactory.zzzz.com" : {

    },
    "registry.gitlab.zzzz.com" : {

    }
  },
  "credHelpers" : {
    "gcr.io" : "gcloud",
    "europe-west1-docker.pkg.dev" : "gcloud"
  }
}
