This class provides the building blocks for someone wanting to use PHP to talk to Proxmox's API. Relatively simple piece of code, just provides a get/put/post/delete abstraction layer as methods on top of Proxmox's REST API, while also handling the Login Ticket headers required for authentication.

See http://pve.proxmox.com/wiki/Proxmox_VE_API for information about how this API works. API spec available at https://pve.proxmox.com/pve-docs/api-viewer/index.html

Requirements:

PHP 5/7/8 with cURL (including SSL/TLS) support.

Usage:

Example - Return status array for each Proxmox Host in this cluster.

require_once("./pve2-api-php-client/pve2_api.class.php");

# You can try/catch exception handle the constructor here if you want.
$pve2 = new PVE2_API("hostname", "username", "realm", "password");
# realm above can be pve, pam or any other realm available.

if ($pve2->login()) {
    foreach ($pve2->get_node_list() as $node_name) {
        print_r($pve2->get("/nodes/".$node_name."/status"));
    }
} else {
    print("Login to Proxmox Host failed.\n");
    exit;
}

Example - Create a new Linux Container (LXC) on the first host in the cluster.

require_once("./pve2-api-php-client/pve2_api.class.php");

# You can try/catch exception handle the constructor here if you want.
$pve2 = new PVE2_API("hostname", "username", "realm", "password");
# realm above can be pve, pam or any other realm available.

if ($pve2->login()) {

    # Get first node name.
    $nodes = $pve2->get_node_list();
    $first_node = $nodes[0];
    unset($nodes);

    # Create a Linux Container (LXC) on the first node in the cluster.
    $new_container_settings = array();
    $new_container_settings['ostemplate'] = "local:vztmpl/debian-6.0-standard_6.0-4_amd64.tar.gz";
    $new_container_settings['vmid'] = "1234";
    $new_container_settings['cpus'] = "2";
    $new_container_settings['description'] = "Test VM using Proxmox 2.0 API";
    $new_container_settings['disk'] = "8";
    $new_container_settings['hostname'] = "testapi.domain.tld";
    $new_container_settings['memory'] = "1024";
    $new_container_settings['nameserver'] = "4.2.2.1";

    // print_r($new_container_settings);
    print("---------------------------\n");

    print_r($pve2->post("/nodes/".$first_node."/lxc", $new_container_settings));
    print("\n\n");
} else {
    print("Login to Proxmox Host failed.\n");
    exit;
}

Example - Modify DNS settings on an existing container on the first host.

require_once("./pve2-api-php-client/pve2_api.class.php");

# You can try/catch exception handle the constructor here if you want.
$pve2 = new PVE2_API("hostname", "username", "realm", "password");
# realm above can be pve, pam or any other realm available.

if ($pve2->login()) {

    # Get first node name.
    $nodes = $pve2->get_node_list();
    $first_node = $nodes[0];
    unset($nodes);

    # Update container settings.
    $container_settings = array();
    $container_settings['nameserver'] = "4.2.2.2";

    # NOTE - replace XXXX with container ID.
    var_dump($pve2->put("/nodes/".$first_node."/lxc/XXXX/config", $container_settings));
} else {
    print("Login to Proxmox Host failed.\n");
    exit;
}

Example - Delete an existing container.

require_once("./pve2-api-php-client/pve2_api.class.php");

# You can try/catch exception handle the constructor here if you want.
$pve2 = new PVE2_API("hostname", "username", "realm", "password");
# realm above can be pve, pam or any other realm available.

if ($pve2->login()) {
    # NOTE - replace XXXX with node short name, and YYYY with container ID.
    var_dump($pve2->delete("/nodes/XXXX/lxc/YYYY"));
} else {
    print("Login to Proxmox Host failed.\n");
    exit;
}
