I don’t understant. I saw somes thread about this, In tried many suggestions about ubuntu, but. Is it sudo from host or sudo into docker? Into docker, I think is root.

Thanks,

The sudo is on the remote shell. Everything, excluding shell-local is remote.

Your execute_command is incorrect, if you like to override the shell then you can include the inline_shebag line, otherwise it defaults to the login shell.

  provisioner "shell" {
    execute_command = "sudo -S env {{ .Vars }} {{ .Path }}"
    inline_shebang  = "/bin/bash -ex"
    ....
 }

Hi,
Thanks!

That is used with your advice:

  provisioner "shell" {
      script = "./configure.sh"
      execute_command = "{{ .Vars }} {{ .Path }}"
      inline_shebang  = "/bin/bash -ex"
  }

I think now it’s another problem with jenkins, the image as jenkins user without sudo and without permissions. And I don’t know how to use root account without password.

If I found, I’ll post it.

Thanks!
