为什么 Terraform 看不到我手动安装的提供程序? [英] Why doesn't Terraform see my manually installed provider?

问题描述

我正在尝试将 RKE 提供程序 安装为Rancher AWS 快速入门的一部分.Terraform 文档 说插件应该安装在 ~/.terraform.d/plugins.RKE 文档说插件应该安装在 ~/terraform.d/plugins/<your_platform>.

I'm trying to install the RKE provider as part of the Rancher AWS quickstart. The Terraform documentation says that plugins should be installed at ~/.terraform.d/plugins. The RKE documentation says that the plugin should be installed at ~/terraform.d/plugins/<your_platform>.

为了协调相互冲突的信息，我尝试将二进制文件复制到以下所有位置，但 Terraform 从未见过它们中的任何一个:

Trying to reconcile the conflicting information, I tried copying the binary to all of the following locations, but Terraform never saw any of them:

~/.terraform.d/plugins/terraform-provider-rke
~/.terraform.d/plugins/rke
~/.terraform.d/plugins/darwin_amd64/terraform-provider-rke
~/.terraform.d/plugins/darwin_amd64/rke
~/terraform.d/plugins/terraform-provider-rke
~/terraform.d/plugins/rke
~/terraform.d/plugins/darwin_amd64/terraform-provider-rke
~/terraform.d/plugins/darwin_amd64/rke

在每种情况下，当我运行 terraform init 时，都会出现以下错误:

In each case, when I ran terraform init, I got the following error:

Provider "rke" not available for installation.

A provider named "rke" could not be found in the Terraform Registry.

This may result from mistyping the provider name, or the given provider may
be a third-party provider that cannot be installed automatically.

In the latter case, the plugin must be installed manually by locating and
downloading a suitable distribution package and placing the plugin's executable
file in the following directory:
    terraform.d/plugins/darwin_amd64

Terraform detects necessary plugins by inspecting the configuration and state.
To view the provider versions requested by each module, run
"terraform providers".


Error: no provider exists with the given name

作为最后的手段，我可​​以使用 terraform init -plugin-dir=<something>.但是随后 Terraform 看不到任何自动下载的插件，我必须手动安装所有内容.

As a last resort, I could use terraform init -plugin-dir=<something>. But then Terraform doesn't see any of the automatically downloaded plugins, and I have to manually install everything.

是否缺少一些路径变量，或者我未能遵循的其他命名约定?

Is there some path variable that's missing, or some other naming convention that I am failing to follow?

推荐答案

原来错误信息并没有说明全部.Terraform 正在寻找提供者，但它认为它的版本不够新.

It turns out that the error message didn't tell the whole story. Terraform was finding the provider, but it didn't think it was a new enough version.

根据Terraform 的文档，提供者需要命名为 terraform-provider-<NAME>_vX.YZ.RKE 提供者的文档 说该文件应该被称为 terraform-provider-rke (没有版本号).

According to Terraform's documentation, the provider needs to be named as terraform-provider-<NAME>_vX.Y.Z. The documentation for the RKE provider said that the file should be called terraform-provider-rke (no version number).

在插件的 Terraform 源代码中的 评论中发现，它表示支持这种无版本格式以实现反向兼容性.但是，Terraform 将版本解释为 v0.0.0.

In a comment in the Terraform source code for plugin discovery, it says that this versionless format is supported for reverse compatibility. However, Terraform interprets the version to be v0.0.0.

当我在失败的 terraform init 之后运行 terraform plan 时，它给了我一个信息更丰富的错误消息:

When I ran terraform plan after the failed terraform init, it gave me a more informative error message:

Error: provider.rke: no suitable version installed
  version requirements: "0.14.1"
  versions installed: "0.0.0"

该版本可能是来自另一个依赖于 RKE 提供者的提供者的要求.

That version is presumably a requirement from another provider that depends on the RKE provider.

我返回并从 Github 存储库手动下载了该确切版本，并将其复制到名为 terraform-provider-rke_v0.14.1 的插件目录中.成功了！

I went back and manually downloaded that exact version from the Github repo and copied it into the plugins directory with the name terraform-provider-rke_v0.14.1. It worked!

所以你去.如有疑问，请查看源代码.现在向 Rancher 提交问题报告，告诉他们更新他们的文档.:-)

So there you go. When in doubt, look at the source code. Now to submit an issue report to Rancher, telling them to update their documentation. :-)
