MAAS API

Restful MAAS API.

This is the documentation for the API that lets you control and query MAAS. The API is "Restful", which means that you access it through normal HTTP requests.

API versions

At any given time, MAAS may support multiple versions of its API. The version number is included in the API's URL, e.g. /api/2.0/

For now, 2.0 is the only supported version.

The current API version number can be retrieved by issuing a GET to "/api/version/". Accessing an old or unknown API version URL will result in a "410 GONE" being returned, along with a descriptive error message. Both the error message and the api version are returned as plaintext.

HTTP methods and parameter-passing

The following HTTP methods are available for accessing the API:

• GET (for information retrieval and queries),
• POST (for asking the system to do things),
• PUT (for updating objects), and
• DELETE (for deleting objects).

All methods except DELETE may take parameters, but they are not all passed in the same way. GET parameters are passed in the URL, as is normal with a GET: "/item/?foo=bar" passes parameter "foo" with value "bar".

POST and PUT are different. Your request should have MIME type "multipart/form-data"; each part represents one parameter (for POST) or attribute (for PUT). Each part is named after the parameter or attribute it contains, and its contents are the conveyed value.

All parameters are in text form. If you need to submit binary data to the API, don't send it as any MIME binary format; instead, send it as a plain text part containing base64-encoded data.

Most resources offer a choice of GET or POST operations. In those cases these methods will take one special parameter, called op, to indicate what it is you want to do.

For example, to list all machines, you might GET "/api/2.0/machines".

This functionality is only available to administrators.

DELETE /api/2.0/commissioning-scripts/{name}

Commissioning scripts

Manage custom commissioning scripts.

This functionality is only available to administrators.

GET /api/2.0/commissioning-scripts/

List commissioning scripts.

POST /api/2.0/commissioning-scripts/

Create a new commissioning script.

Each commissioning script is identified by a unique name.

By convention the name should consist of a two-digit number, a dash, and a brief descriptive identifier consisting only of ASCII characters. You don't need to follow this convention, but not doing so opens you up to risks w.r.t. encoding and ordering. The name must not contain any whitespace, quotes, or apostrophes.

A commissioning machine will run each of the scripts in lexicographical order. There are no promises about how non-ASCII characters are sorted, or even how upper-case letters are sorted relative to lower-case letters. So where ordering matters, use unique numbers.

Scripts built into MAAS will have names starting with "00-maas" or "99-maas" to ensure that they run first or last, respectively.

Usually a commissioning script will be just that, a script. Ideally a script should be ASCII text to avoid any confusion over encoding. But in some cases a commissioning script might consist of a binary tool provided by a hardware vendor. Either way, the script gets passed to the commissioning machine in the exact form in which it was uploaded.

• param name Unique identifying name for the script. Names should follow the pattern of "25-burn-in-hard-disk" (all ASCII, and with numbers greater than zero, and generally no "weird" characters).

• param content A script file, to be uploaded in binary form. Note: this is not a normal parameter, but a file upload. Its filename is ignored; MAAS will know it by the name you pass to the request.

Lists all discovered devices which have an unknown IP address.

Filters the list of discovered devices by excluding any discoveries where a known MAAS node is configured with the IP address of the discovery, or has been observed using it after it was assigned by a MAAS-managed DHCP server.

Discoveries are listed in the order they were last observed on the network (most recent first).

GET /api/2.0/discovery/ op=by_unknown_ip_and_mac

Lists all discovered devices which are completely unknown to MAAS.

Filters the list of discovered devices by excluding any discoveries where a known MAAS node is configured with either the MAC address or the IP address of the discovery.

GET /api/2.0/discovery/ op=by_unknown_mac

Lists all discovered devices which have an unknown IP address.

Filters the list of discovered devices by excluding any discoveries where an interface known to MAAS is configured with MAC address of the discovery.

Discoveries are listed in the order they were last observed on the network (most recent first).

POST /api/2.0/discovery/ op=clear

Deletes all discovered neighbours and/or mDNS entries.

• param mdns if True, deletes all mDNS entries.

• param neighbours if True, deletes all neighbour entries.

• param all if True, deletes all discovery data.

POST /api/2.0/discovery/ op=scan

Immediately run a neighbour discovery scan on all rack networks.

This command causes each connected rack controller to execute the 'maas-rack scan-network' command, which will scan all CIDRs configured on the rack controller using 'nmap' (if it is installed) or 'ping'.

Network discovery must not be set to 'disabled' for this command to be useful.

Scanning will be started in the background, and could take a long time on rack controllers that do not have 'nmap' installed and are connected to large networks.

If the call is a success, this method will return a dictionary of results as follows:

result: A human-readable string summarizing the results. scan_attempted_on: A list of rack 'system_id' values where a scan was attempted. (That is, an RPC connection was successful and a subsequent call was intended.)

failed_to_connect_to: A list of rack 'system_id' values where the RPC connection failed.

scan_started_on: A list of rack 'system_id' values where a scan was successfully started.

scan_failed_on: A list of rack 'system_id' values where a scan was attempted, but failed because a scan was already in progress.

rpc_call_timed_out_on: A list of rack 'system_id' values where the RPC connection was made, but the call timed out before a ten second timeout elapsed.

• param cidr The subnet CIDR(s) to scan (can be specified multiple times). If not specified, defaults to all networks.

• param force If True, will force the scan, even if all networks are specified. (This may not be the best idea, depending on acceptable use agreements, and the politics of the organization that owns the network.) Default: False.

• param always\_use\_ping If True, will force the scan to use 'ping' even if 'nmap' is installed. Default: False.

• param slow If True, and 'nmap' is being used, will limit the scan to nine packets per second. If the scanner is 'ping', this option has no effect. Default: False.

• param threads The number of threads to use during scanning. If 'nmap' is the scanner, the default is one thread per 'nmap' process. If 'ping' is the scanner, the default is four threads per CPU.

POST /api/2.0/machines/{system_id}/ op=clear_default_gateways

Clear any set default gateways on the machine.

This will clear both IPv4 and IPv6 gateways on the machine. This will transition the logic of identifing the best gateway to MAAS. This logic is determined based the following criteria:

1. Managed subnets over unmanaged subnets.
2. Bond interfaces over physical interfaces.
3. Machine's boot interface over all other interfaces except bonds.
4. Physical interfaces over VLAN interfaces.
5. Sticky IP links over user reserved IP links.
6. User reserved IP links over auto IP links.

If the default gateways need to be specific for this machine you can set which interface and subnet's gateway to use when this machine is deployed with the interfaces set-default-gateway API.

Returns 404 if the machine could not be found. Returns 403 if the user does not have permission to clear the default gateways.

• param subnets Subnets that must be linked to the machine.

"Linked to" means the node must be configured to acquire an address in the specified subnet, have a static IP address in the specified subnet, or have been observed to DHCP from the specified subnet during commissioning time (which implies that it could have an address on the specified subnet).

Subnets can be specified by one of the following criteria:

• <id>: match the subnet by its 'id' field
• fabric:<fabric-spec>: match all subnets in a given fabric.
• ip:<ip-address>: Match the subnet containing <ip-address> with the with the longest-prefix match.

• vlan:<vlan-spec>: Match all subnets on the given VLAN.

Note that (as of this writing), the 'fabric', 'space', 'vid', and 'vlan' specifiers are only useful for the 'not_spaces' version of this constraint, because they will most likely force the query to match ALL the subnets in each fabric, space, or VLAN, and thus not return any nodes. (This is not a particularly useful behavior, so may be changed in the future.)

If multiple subnets are specified, the machine must be associated with all of them. To request multiple subnets, this parameter must be repeated in the request with each value.

Note that this replaces the leagcy 'networks' constraint in MAAS 1.x.
