Terraform Version

Terraform v1.11.1 on linux_amd64

Steps to Reproduce

On Visual studio Code, when running on Alpine via a devcontainer on in WSL2 and trying to install the extension, we get a NotSigned error.

Error while installing the extension hashicorp.terraform Signature verification failed with 'NotSigned'

Expected Behavior

The extension should be installed as it is when the dev container or the WSL2 distribution is Archlinux, for instance.

Actual Behavior

we get a NotSigned error.

Error while installing the extension hashicorp.terraform Signature verification failed with 'NotSigned'

Anything Else?

The problem occurs is because on Alpine, vscode expects a target platform of alpine-x64 or alpine-arm64, probably because of the peculiar libc used, musl. As it is not provided, vscode falls back to a universal 2.19.0 version that is unsigned.

I'm not sure this is enough, but it may be sufficient to add the appropriate target platforms on the deployment matrix in:

vscode-terraform/.github/workflows/deploy.yml

Lines 26 to 51 in 04feeeb

	matrix:
	include:
	- vsce_target: web
	ls_target: web_noop
	npm_config_arch: x64
	- vsce_target: win32-x64
	ls_target: windows_amd64
	npm_config_arch: x64
	- vsce_target: win32-arm64
	ls_target: windows_arm64
	npm_config_arch: arm
	- vsce_target: linux-x64
	ls_target: linux_amd64
	npm_config_arch: x64
	- vsce_target: linux-arm64
	ls_target: linux_arm64
	npm_config_arch: arm64
	- vsce_target: linux-armhf
	ls_target: linux_arm
	npm_config_arch: arm
	- vsce_target: darwin-x64
	ls_target: darwin_amd64
	npm_config_arch: x64
	- vsce_target: darwin-arm64
	ls_target: darwin_arm64
	npm_config_arch: arm64

By adding:

          - vsce_target: alpine-x64
            ls_target: linux_amd64
            npm_config_arch: x64
          - vsce_target: alpine-arm64
            ls_target: linux_arm64
            npm_config_arch: arm64

Workarounds

Download the linux-x64 VSIX file and install locally. Because the binary terraform-ls is statically linked, it works.
