VM proxy configuration

[Thibaud Lepretre]

I'm using packer inside "proxified" network and I know that packer is using standard proxy env variables:

- http_proxy

- https_proxy

But my problem is located inside VM and when I want to provisioned its VM I must add the following configuration at each provisioners:

{

    "variables": {

        "http_proxy": "{{env `http_proxy`}}",

        "https_proxy": "{{env `https_proxy`}}",

        "ftp_proxy": "{{env `ftp_proxy`}}",

        "no_proxy": "{{env `no_proxy`}}"

    },

    ...

    "provisioners": [

        {

            "only": ["virtualbox-iso"],

            "environment_vars": [

                "http_proxy={{user `http_proxy`}}",

                "https_proxy={{user `https_proxy`}}",

                "ftp_proxy={{user `ftp_proxy`}}",

                "no_proxy={{user `no_proxy`}}"

            ],

            "type": "shell",

            "execute_command": "echo 'vagrant' | {{.Vars}} sudo -S -E bash '{{.Path}}'",

            "scripts": [

                ...

            ]

        },

        {

            "environment_vars": [

                "http_proxy={{user `http_proxy`}}",

                "https_proxy={{user `https_proxy`}}",

                "ftp_proxy={{user `ftp_proxy`}}",

                "no_proxy={{user `no_proxy`}}"

            ],

            "type": "shell",

            "execute_command": "echo 'vagrant' | {{.Vars}} sudo -S -E bash '{{.Path}}'",

            "inline": ["yum update"]

        }

    ]

}

It's a bit redundant.

There is a better way to achieve my goal?

you can have 1 shell code, and use

[

"command....",

"command..",

"command"

]

no need to write a full block for each line/command

Yeah but I have to split the commands because somes are only for provider virtualbox-iso and other are default (for all provider)

I believe packer now supports the concept of "overrides" for specific providers, so you can use the common blocks and just override commands for specific providers.
