# Installing Custom Software
|
|
|
|
|
|
|
|
|
|
The machines that run Terraform exist in an isolated environment and are
|
|
|
|
|
destroyed on each use. In some cases, it may be necessary to install certain
|
|
|
|
|
software on the Terraform runner, such as a configuration management tool like
|
|
|
|
|
Chef, Puppet, Ansible, or Salt.
|
|
|
|
|
|
|
|
|
|
The easiest way to install software on the Packer builder is via the
|
|
|
|
|
`local-exec` provisioner. This will execute commands on the host machine running
|
|
|
|
|
Terraform.
|
|
|
|
|
|
|
|
|
|
resource "null_resource" "local-software" {
|
|
|
|
|
provisioner "local-exec" {
|
|
|
|
|
command = <<EOH
|
|
|
|
|
sudo apt-get update
|
|
|
|
|
sudo apt-get install -y ansible
|
|
|
|
|
EOH
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
|
|
|
|
|
Please note that nothing is persisted between Terraform runs, so you will need
|
|
|
|
|
to install custom software on each run.
|
|
|
|
|
|
|
|
|
|
The Packer builders run the latest version of Ubuntu LTS.
