BMC Server Management via API

Introduction

The Bare Metal Cloud APIs provide additional flexibility when working with phoenixNAP BMC products. With the APIs herein, you can organize resources by using tags, monitor system logs and API activities for your BMC account, and control private networks for your BMC instances.

In this article, you will get familiar with the following Bare Metal Cloud APIs:

• Server Tag Manager API
• Audit Log API
• Multi-Private Backend Network API
• Public Network API

Server Tag Manager API

The Tag Manager API lets users create tags to organize and group servers. You can also filter the resources by tag names or a tag name and value. Hence, tags are key-value pairs that simplify the Bare Metal Cloud server management.

The Tag Manager API uses this HTTP request:

https://api.phoenixnap.com/tag-manager/v1/tags

and the following methods:

• POST - Create a new tag in the tag inventory.
• GET - Retrieve information for your tags and the tag inventory.
• PATCH - Modify/update a tag from the inventory.
• DELETE - Delete a tag from the inventory.

Create Tag

To add a tag using the POST request requires the tag body to contain a tag name and the value for the isBillingTag property (true or false). This property instructs whether the invoice should use the tag to display the servers with recurring costs. The tag description property is optional.

For instance, to create ExampleTag, use the /tags endpoint and:

Once you create a tag, it gets a unique ID. You can use the tag name or ID for API requests.

View Tags and Tag Inventory

Use the GET request and the /tags endpoint to view all tags that belong to your BMC account. In our case, we have the tag Environment and the ExampleTag we created above.

The output lists all tags in the inventory with all properties and their current values.

To view a specific tag and its properties, use the /tags/{tagId} endpoint.

Modify a Tag

Use the PATCH method with the /tags/{tagId} endpoint to update a tag's values. For example, change the isBillingTag from false to true.

If you patch the isBillingTag property, the tag changes on all assigned resources.

Delete a Tag

To completely remove a tag from your BMC account, use the DELETE method with the /tags/{tagId} endpoint.

Assign Tag to Server Resources

Use the PUT method and the /servers/{serverId}/tags to assign a tag to a BMC server. The tag body must contain a tag name, while the value property can be left empty. However, if this property is populated, you can have multiple servers using the same tag with a different value.

For instance, set the environment tag with the value prod to one BMC server and use the same tag name for another server but with the value QA. Therefore, you can assign one tag to multiple servers but use a different value.

When you request tag details, the body of the tag shows the fields gathered from the server it is assigned to. When the same tag is assigned to multiple BMC servers with different values, then the tag shows that information as well.

If you remove a tag assignment from a resource, the system updates the tag details automatically.

Having tags assigned to servers facilitates resource usage organization when different teams work on multiple projects. Additionally, businesses get a clear breakdown in the invoices for the server usage for their BMC account.

Filter Servers by Using Tags

You can filter BMC servers by using a tag name and tag value if a server has any tags assigned.

Use the GET method in this format to filter server resources:

/servers/?tag=tagName.tagValue

Use multiple query parameters to refine the filtering:

/servers/?tag=tagName.tagValue&tagName2.tagValue2

Specifying the tag value is optional, so use the tag name to filter the server resources only.

/servers/?tag=tagName

For example:

/servers/?tag=Environment

The query result shows all servers that match the filtering parameters.

Audit Log API

The BMC Audit Log API allows you to monitor API calls and activities on your Bare Metal Cloud account. The system records user actions by creating event logs for each API action automatically.

With this API, you can read the audit log entries and maintain the required security level. The Audit Log API provides business owners the transparency they need to maintain operational best practices.

For example, the system logs when there is an error message or action such as powering off a server, restarting, billing changes, deleting an SSH key, and similar.

Users can see audit logs for their own accounts only.

Retrieve Event Logs

To retrieve API event logs, use the GET method and this request:

https://api.phoenixnap.com/audit/v1/events

Use different query parameters to customize the filter result:

• Limit. Instructs the API to limit the response output to a specified number of events. The endpoint is
  /events?limit=value.
• Verb. Shows the results for the specified verb events. For example, to see the POST events, use the
  /events?verb=POST endpoint.
• Username. Displays the API event log for the specified username. The endpoint is
  /events?username=value.
• Order. Set the sorting order of the event audit log according to the time stamp in ascending (ASC) or descending (DESC) order. The default is DESC if no value is specified. The endpoint is
  /events?order=ASC_or_DESC.
• Date. Filters by the specified date range using from and to. The endpoint is
  /events?from=data&to=date.

Multi-Private Backend Network API

The multi-private backend feature provides added control and flexibility when using private networks with BMC servers. With the multi-private backend networking APIs, users can now customize private IP space when provisioning a server.

The HTTP Request URL is:

https://api.phoenixnap.com/networks/v1/private-networks

The Network API has the following properties:

Property	Input​	Description​
ID​	system​	Unique network identifier​ assigned by the system.
Name​	required	The network name must be unique for all networks for an account. (case insensitive)​
Description​	optional	Network description​, if not defined it will be nulled.
Type​	​system	A field returned for backend networks, in this case PRIVATE.
Location​	required	Network location​.
Location Default​	required ​	Boolean representing the default network for an account in a location​.
CIDR​	required ​	Network subnet from which users can assign IP addresses.
VLAN ID​	​system	Client VLAN ID used for issue reporting in case of network problems.​
Servers​	​system	List of servers assigned to the network in question​.

This API allows users to:

• Provision a server and assign it to a specific private network. If no network details are specified, then the system adds a server to the default network for the location and automatically assigns the first available IP. For example, provision a server within multiple private networks and specify network settings for each. One server can be assigned up to 10 private IP addresses. It is not possible to combine different networks, and only one gateway is supported.

• Add an existing server to another private network. This can be any network for that location. You can also assign multiple networks in the same manner as when you provision a server.
• Remove an existing server from a private network. You can remove a server from any private network, even when that is the only network the server is connected to. When you deprovision a server, the server is removed from any associated private networks, and the IP allocation is freed up.

Below is the table of the default private networks for all locations:

Location​	CIDR​
Phoenix​ (PHX)	10.0.0.0/24​
Ashburn (ASH)	10.1.0.0/24​
Singapore​ (SGP)	10.2.0.0/24​
Netherlands (NLD)	10.3.0.0/24​
Chicago (CHI)	10.4.0.0/24​
Seattle​ (SEA)	10.5.0.0/24​
Austin (USA)	10.6.0.0/24​

Create Private Network API

Use the POST method and the /private-networks endpoint to create a private network.

The request contains the following fields:

• name
• location
• locationDefault
• cidr
  • Supported ranges are:
    • 10.0.0.0 – 10.255.255.255
    • 172.16.0.0 – 172.31.255.255
    • 192.168.0.0. – 192.168.255.255
• description (optional)

For example:

Retrieve Private Network Details

Use the GET method and the /private-networks endpoint to retrieve the list of all private networks for all locations owned by the account.

To get the details of a specific private network, use the /private-networks/{network_id}​ endpoint.

The result also shows the servers assigned to a private network with server IDs and IPs.

Optionally, filter the results by the location with this endpoint:

/private-networks?location=PHX

Replace PHX with the desired location.

Modify Private Network

Use the PUT method and the /private-networks/{network_id}​ endpoint to update a private network's details.

The fields you can modify are:

• name - either leave the same name or specify a new unique name.
• locationDefault - for example, if a network is not default, set the value to true to make that network default. Only one network can be default per location.
• description - optional field.

Delete Private Network

To remove a known private network, use the DELETE method and the /private-networks/{network_id}​ endpoint. 

Once you delete a network, you cannot retrieve any previous information on it.

Public Network API

The public network API lets you create and manage public networks. A public network allows numerous servers to be connected to the same network and have internet access, as opposed to private networks. BMC servers can have multiple public networks with multiple public IP blocks the user purchased.

The HTTP Request URL for the Public Network API is:

https://api.phoenixnap.com/networks/v1/public-networks

Create Public Network

Use the POST method and the /public-networks endpoint to create a public network. The maximum number of networks per account is 15.

The body can contain the following fields:

• name (required) - must be unique.
• location (required) - available locations are: PHX, ASH, SGP, NLD, CHI, SEA, and, AUS.
• description (optional)
• ipBlocks (optional) - specify up to ten IDs of the IP blocks you purchased previously.

For example, to create a public network with two previously purchased IP blocks, use:

{
  "name": "BMC public network",
  "location": "PHX",
  "description": "My first public network test",
  "ipBlocks": [
    {
      "id": "60473a6115e34466c9g8f083"
    },
    {
      "id": "613b51c01f4b04615da1d3be"
    }
  ]
}

Retrieve Public Network Details

Use the GET method and the /public-networks endpoint to retrieve the details of all public networks for all locations owned by the account. The response lists the information available for all public networks.

To filter the results by the location, use this endpoint:

https://api.phoenixnap.com/networks/v1/public-networks?location=PHX

To view the details of a single public network, use the /public-networks/{publicNetworkId}​ endpoint.

For example:

https://api.phoenixnap.com/networks/v1/public-networks/603f3b2cfcaf050643b89afd

If BMC servers are part of the network, the response shows their IDs, type, and IPs added to the server:

Modify Public Network

Use the PATCH method and the /public-networks/{publicNetworkId}​ endpoint to update a public network's details.

The fields you can update are:

• name - specify a new unique name for the public network or leave it unchanged.
• description - update the public network description.

For example:

{
  "name": "New public network",
  "description": "The updated description of my public network"
}

Delete Public Network

To remove a public network, use the DELETE method and the /public-networks/{publicNetworkId} endpoint.

Add IP Block to Public Network

To add an IP block to a public network, use the POST method and this HTTP request URL:

https://api.phoenixnap.com/networks/v1/public-networks/{publicNetworkId}/ip-blocks

There are a few requirements when adding an IP block to a public network:

• An IP block must not be assigned to a network or server.
• An IP block must be in the same location as the public network.
• The minimum CIDR block size is /29, and the maximum is /22.
• A public network can have a maximum of 10 assigned IP blocks.

Specify the IP block ID in the body of the request to add it to the public network.

For example:

{  
  "id": "60473a6115e34466c9f8f083"
}

Delete IP Block from Public Network

To remove an IP block from a public network, use the DELETE method and this HTTP request URL:

https://api.phoenixnap.com/networks/v1/public-networks/{publicNetworkId}/ip-blocks/{ipBlockId}

For example:

https://api.phoenixnap.com/networks/v1/public-networks/603f3b2cfcaf050643b12a4b/ip-blocks/6047127fed34ecc3ba8401c1

Make sure no resource within this network has IPs assigned from the IP block you want to remove.

Add Server to Public Network (Server API)

Use the POST method with the servers endpoint to add a server to an existing public network. The server must be in the same location as the network and can be powered on, powered off, or rebooting when you make the API call.

The HTTP request URL is:

https://api.phoenixnap.com/bmc/v1/servers/{serverId}/network-configuration/public-network-configuration/public-networks

The body of the request must contain the public network ID and the IPs you want to add to the server. Also, the IPs need to be in the CIDR range of any IP block assigned to the public network in question.

Remove Server from Public Network (Server API)

Use the DELETE method with the bmc servers endpoint to remove a server from a public network. When deleting a network, manual OS-level network configuration is required.

The HTTP request is:

https://api.phoenixnap.com/bmc/v1/servers/{serverId}/network-configuration/public-network-configuration/public-networks/{publicNetworkId}
