Wouldn't it be nice if you could run goss tests against an image during a packer build?

Well, I thought it would, so now you can! This currently only works for building a linux image since goss only runs in linux.

This runs during the provisioning process since the machine being provisioned is only available at that time.

There is an example packer build with goss tests in the example/ directory.

"provisioners" : [
  {
    "type": "goss",
    "tests": [
      "goss/goss.yaml"
    ]
  }
]

"provisioners" : [
  {
    # Packer Args
    "type": "goss",

    # Packer Provisioner Args
    "arch": "amd64",
    "downloadPath": "/tmp/goss-VERSION-linux-ARCH",
    "inspect": "{{user `inspect_mode`}}",
    "password": "",
    "skipInstall": false,
    "url":"https://github.com/aelsabbahy/goss/releases/download/vVERSION/goss-linux-ARCH",
    "username": "",
    "version": "0.3.2",

    # GOSS Args
    "tests": [
      "goss/goss.yaml"
    ],
    "remote_folder": "/tmp",
    "remote_path": "/tmp/goss",
    "skip_ssl": false,
    "use_sudo": false,
    "format": "",
    "goss_file": "",
    "vars_file": "",
    "vars_env": {
      "ARCH": "amd64",
      "PROVIDER": "{{user `cloud-provider`}}"
    },
    "vars_inline": {
      "OS": "centos",
      "version": "{{user `version`}}"
    },
    "retry_timeout": "0s",
    "sleep": "1s"
  }
]

1. Download the most recent release for your platform from here..

2. Rename the binary to packer-provisioner-goss

3. Place the file in one of the directories where packer looks for plugins:

Once the plugin is named properly, Packer automatically discovers plugins in the following directories in the given order. If a conflicting plugin is found later, it will take precedence over one found earlier.

The directory where packer is, or the executable directory.

~/.packer.d/plugins on Unix systems or %APPDATA%/packer.d/plugins on Windows.

The current working directory.

4. Set binary to be executable chmod x packer-provisioner-goss

docker run --rm -it -v "$PWD":/usr/src/packer-provisioner-goss -w /usr/src/packer-provisioner-goss -e 'VERSION=v1.0.0' golang:1.13 bash
for GOOS in darwin linux windows; do
  for GOARCH in 386 amd64; do
    export GOOS GOARCH
      go get -v ./...
      go build -v -o packer-provisioner-goss-${VERSION}-$GOOS-$GOARCH
  done
done
