Terraform 自定义提供程序 GPG 问题

Terraform custom provider GPG issue

希望你一切顺利。

我正在写一个在 Go 中使用的 API,其工作方式类似于 terraform provider protocol

所以我已经有两个端点通过 HTTPS 在我的本地计算机上工作:

让我们举例说明这些完整端点:

所以我有下一个 .tf.json 文件:

{
    "module": {
        "linux": {
            "source": "myapi:9000/v1/module/mymodule/custom",
            "version": "0.1.2"
        }
    }
}

即使用这两个文件

  1. 提供商。tf.json
provider "mycustomprovider" {
    username = "abc"
    password = "def"
    host = "yjk"
}
  1. 版本。tf.json
terraform {
    required_providers {
        mycustomprovider = {
            source: "myapi:9000/v1/myprovider/custom",
            version: "0.1.0"
        }
    }
    required_version = ">=1.0.2"
}

然后我直接运行:terraform init得到我的资产

所以,当我得到我的自定义模块时,它工作正常。 输出(模块下载):

Initializing modules...
Downloading myapi:9000/mymodule/custom/gnu 0.1.2 for linux...
- linux in .terraform/modules/linux

Initializing the backend...

但是当我得到我的 provdier 时我有这个错误:

Initializing provider plugins...
- Finding myapi:9000:9000/myprovider/custom versions matching "0.1.0"...
- Installing myapi:9000:9000/myprovider/custom v0.1.0...
╷
│ Error: Failed to install provider
│ 
│ Error while installing myapi:9000/myprovider/custom v0.1.0: error checking signature:
│ openpgp: invalid data: tag byte does not have MSB set

所以,我的提供商 versions 端点正在运行。这就是为什么 terraform 能够识别我的提供商的版本。

问题应该出在我的 download 端点上。

在谈论这个端点之前,我想添加一些上下文,我正在 运行 使用 localstack and exposing it through ngrok 创建一个 S3 客户端。这两件事有效,我可以毫无问题地上传或下载文件。

Terraform 自定义提供程序应具有三个文件(据我了解):

  1. zip 格式的提供程序(如他们的示例)
  2. 一个 provider_SHA256SUMS 文件,其中包含每个提供商 zip 文件的 shasums(在这种情况下,我只有一个)
  3. a provider_SHA256SUMS.sig 用于识别 provider_SHA256SUMS 文件的完整性。

因此,为了获取这些文件,我运行正在执行这些命令:

provider_SHA256SUMS

$ sha256sum 0.1.0.zip > 0.1.0_SHA256SUMS

provider_SHA256SUMS

$ gpg --gen-key # generating a new key
$ gpg --armor --output 0.1.0_SHA256SUMS.sig --detach-sig 0.1.0_SHA256SUMS

我端点的响应是这样的。 (gpg 信息只是示例数据,此处没有真正的警告。)

响应中的shasum属性应该是对应provider zip文件的shasum,也可以在provider_SHA256SUMS文件中找到。

为了获得 key_idascii_armor 道具,我正在 运行 执行以下命令:

$ gpg --list-secret-keys --keyid-format=long ## key_id
$ gpg --armor --export <MY_KEYID> > public.gpg ## export to public key to base64
$ cat public.gpg | sed -E ':a;N;$!ba;s/\r{0,1}\n/\n/g' ## one-lined ascii_armor

小问题

我在使用 gpg 密钥时做错了什么导致出现此错误?是我步骤不够,还是做错了?

openpgp: invalid data: tag byte does not have MSB set

----更新----

这就是我在 Go 中构建响应的方式:

我没有给出完整的代码,因为我认为问题出在 KeyIDASCIIArmor 属性上。

如您所见:ShasumKeyIDASCIIArmor 是硬编码的。

terraform 使用的

x/crypto/openpgp 不支持读取装甲消息,参见 issue,这是错误的来源。

shasums_signature_url 归档文档提到:

binary, detached GPG signature

另请参阅 Manually preparing a release doc

which is a valid GPG binary (not ASCII armored) signature

所以你应该尝试在没有 --armor 标志的情况下签名。
