Unable to install plugin

[tormodmacleod]

Hello,

It seems the absence of a checksum file makes it difficult to install the plugin

$ cat plugins.pkr.hcl 
packer {
  required_plugins {
    amazon = {
      version = "1.3.3"
      source  = "github.com/hashicorp/amazon"
    }
    ansible = {
      version = "1.1.2"
      source  = "github.com/hashicorp/ansible"
    }
    podman = {
      version = "1.0.0"
      source  = "github.com/Polpetta/podman"
    }
  }
}

$ packer-io init plugins.pkr.hcl
Installed plugin github.com/hashicorp/amazon v1.3.3 in "/home/tormod/.packer.d/plugins/github.com/hashicorp/amazon/packer-plugin-amazon_v1.3.3_x5.0_linux_amd64"
Installed plugin github.com/hashicorp/ansible v1.1.2 in "/home/tormod/.packer.d/plugins/github.com/hashicorp/ansible/packer-plugin-ansible_v1.1.2_x5.0_linux_amd64"
Failed getting the "github.com/Polpetta/podman" plugin:
2 errors occurred:
        * could not get sha256 checksum file for github.com/Polpetta/podman version 1.0.0. Is the file present on the release and correctly named ? GET https://github.com/Polpetta/packer-plugin-podman/releases/download/v1.0.0/packer-plugin-podman_v1.0.0_SHA256SUMS: 404  []
        * could not install any compatible version of plugin "github.com/Polpetta/podman"

I assume it's to do with the fact that the release of 1.0.0 contains only v1.0.0.zip & v1.0.0.tar.gz where previous releases included checksums et cetera

That does in fact seem to be the issue:

$ packer init .            
Failed getting the "github.com/Polpetta/podman" plugin:

to solve it you need to build the plugin first:
cd ./<path-to>/packer-plugin-podman

Once inside the folder run the following command
go build -o packer-plugin-podman

To install it run the following command.
Note the name of the output plug in does not matter can be either packer-plugin-podman or just podman
packer plugins install --path="../packer-plugin-podman/packer-plugin-podman" "github.com/Polpetta/podman

Additional note, on your packer configuration file name.pkr.hcl make sure it shows as the following; otherwise, you will get an error.
The reason of the error is because the value of source can't have github.com/Polpetta/packer-plugin-<binary-name>"
packer { required_plugins { podman = { version = ">=v0.1.0" source = "github.com/Polpetta/podman" } } }
