Chef Provisioner
The chef
provisioner installs, configures and runs the Chef Client on a remote
resource. The chef
provisioner supports both ssh
and winrm
type
connections.
-> Note: This provisioner has been deprecated as of Terraform 0.13.3 and will be removed in a future version of Terraform. For most common situations there are better alternatives to using provisioners. For more information, see the main Provisioners page.
Requirements
The chef
provisioner has some prerequisites for specific connection types:
- For
ssh
type connections,cURL
must be available on the remote host. - For
winrm
connections,PowerShell 2.0
must be available on the remote host.
Chef end user license agreement must be accepted by setting chef_license
to accept
in client_options
argument unless you are installing an old version of Chef client.
Without these prerequisites, your provisioning execution will fail.
Example usage

# ...

{
"key": "value",

"webserver2"
]
}
}
}
EOF
