Re: [packer] sudo script with packer

[Alvaro Miranda Aguilera]

Hello,

What command you should type on the command line to get this working?

I am not sure if you are telling the packer template to run as root, abc or other user, so the line you would type will help to understand better.

Thanks

Alvaro.

Hi,

I would like to do following :-

login with ec2-user .. and sudo to some other user and execute deployment script. 

So, packer working fine.. AMI creation is ok.. But while executing below script it gives me an error that it should run with "abc" user and not root user.

I have added ec2-user in sudoers files :-

ec2-user ALL=(ALL) <script path>

"provisioners": [

   {

        "type": "shell",

        "execute_command": "echo '' | sudo -S sh '{{ .Path }}'",

        "environment_vars": [

                                "SUDO_USER={{user `dep_user`}}"

                        ],

        "scripts": [

                                "/eserver1/share/deployment_kit/deploy.sh"

                ]

   }

In variables :- 

"dep_user": "abc",

Can you please tell where it's wrong ?

Regards,

Sudh

Hi Alvaro,

Thx for your reply..

So, login with ec2-user and then following command :-

sudo su - abc -c "<script-name>"..

You can also use sudo -u to specify the user e.g:

sudo -u abc [command]

Hello,

Ah, well, 2 options here.

You are running as root that command

arguments="su - abc -c <script-name>"

so in your packer script you can just do

"provisioners": [

   {

        "type": "shell",

        "execute_command": "echo '' | sudo -S su - abc -c '{{ .Path }}'",

        "scripts": [

                                "/eserver1/share/deployment_kit/deploy.sh"

                ]

   }

^ this should run since is run as root and root should have access too all commands

As Chris said, the command should be

sudo -u abc "<script-name>"

so in packer:

"provisioners": [

   {

        "type": "shell",

        "execute_command": "echo '' | sudo -S -u abc '{{ .Path }}'",

        "scripts": [

                                "/eserver1/share/deployment_kit/deploy.sh"

                ]

   }

^ problem with that is the path won't be the same, the path of the script will be changed to `/tmp/<something>` so it will fail

if user that you use to login have access to run any command, as any user then should work.

Hope this helps.

Alvaro.
