linode-api top

An api for linode

New plans, including top

**WARNING** Plan numbers have change, so be careful with 
old versions as they will create a different linode than 
the version 3

This supercedes version 1 and 2 - which are now considered deprecated.

Major differences:

  • All errors returned in the JSON payload now throw an ApiException with the JSON error array as the message.
  • All responses are now fully parsed into beans for easy access.
  • High Level API convenience methods for easy creation of linodes
  • Caching of Availability calls
  • Swapped to slf4j over java.util.logging
  • Package refactoring

The api calls are automatically generated from the https://www.linode.com/api pages so that they are kept in sync.

Usage top

Requirements top

  1. A linode Account - sign up/sign in for one here: www.linode.com
  2. A linode API Access key - once you are logged in, go here to create one https://manager.linode.com/profile/api
  3. that's it!

Creating a Linode top

High Level Facade

This is designed to get a linode up and running as quickly as possible. This provides a very small subset of available calls.

Note that LinodeApiHighLevel has been renamed to LinodeApifacade


LinodeApiFacade linodeApiFacade = new LinodeApiFacade("YOUR_API_KEY_GOES_HERE");

linodeApiFacade.createLinode(...);

/**
 * Create and boot a linode in a datacenter, for a specific plan, using a
 * specific distribution.
 * 
 * @param datacenter the id of the datacenter to launch the linode in
 * @param plan the id of the linode plan 
 * @param distribution the distribution that fills the root disk
 * @param kernel the kernel to use
 * @param label the label for this linode
 * @param rootPassword the root password
 * 
 * @return the id of the linode that was created
 * 
 * @throws ApiException if there was an error creating the linode
 */
public Long createLinode(DatacenterSlug datacenter, 
		PlanSlug plan, 
		DistributionSlug distribution, 
		KernelSlug kernel, 
		String label,
		String rootPassword) throws ApiException

Finding the IP address(es) of the newly created linode

// 'linodeId' is the ID of the newly created linode, the second
// parameter 'null' is the linode ipAddressId (which we don't know
// yet...

List<IPAddress> ipAddresses = linodeApi.getLinodeIpList(linodeId, null).getIpAddresses();

for (IPAddress ipAddress : ipAddresses) {
	System.out.println(ipAddress.getIpAddress() + " is public?: " + ipAddress.getIsPublic());
}

Low Level Interface

The general flow is

  1. Choose a datacenter
  2. Choose a plan
  3. Choose a kernel
  4. Choose a distribution
  5. Create a linode
  6. Create the disks (2 are required)
  7. Create a configuration for the linode
  8. Boot the linode

Calling the API (deprecated) top

These are deprecated and the LinodeApi or LinodeApiFacade objects should be used instead

Single Requests

// create a  linodeApi object
LinodeApi linodeApi = new LinodeApi("<YOUR_SUPER_SECRET_API_KEY>");

// create a single request to get the available datacentres
LinodeResponse linodeResponse = linodeApi.execute(Avail.datacenters());

// the response should look something like this:

{
   "ERRORARRAY":[],
   "ACTION":"avail.datacenters",
   "DATA":[
      {
         "DATACENTERID":2,
         "LOCATION":"Dallas, TX, USA",
         "ABBR":"dallas"
      },
      {
         "DATACENTERID":3,
         "LOCATION":"Fremont, CA, USA",
         "ABBR":"fremont"
      },
      {
         "DATACENTERID":4,
         "LOCATION":"Atlanta, GA, USA",
         "ABBR":"atlanta"
      },
      {
         "DATACENTERID":6,
         "LOCATION":"Newark, NJ, USA",
         "ABBR":"newark"
      },
      {
         "DATACENTERID":7,
         "LOCATION":"London, England, UK",
         "ABBR":"london"
      },
      {
         "DATACENTERID":8,
         "LOCATION":"Tokyo, JP",
         "ABBR":"tokyo"
      },
      {
          "DATACENTERID":9,
          "LOCATION":"Singapore, SG",
          "ABBR":"singapore"
      },
      {
          "DATACENTERID":10,
          "LOCATION":"Frankfurt, DE",
          "ABBR":"frankfurt"
      }
   ]
}

Multiple Requests

// create a  linodeApi object
LinodeApi linodeApi = new LinodeApi("<YOUR_SUPER_SECRET_API_KEY>");

// create an list of requests to perform
List<LinodeRequest> linodeRequests = new ArrayList<LinodeRequest>();

// add in the requests
linodeRequests.add(Avail.datacenters());
linodeRequests.add(Avail.distributions());

// perform the requests and get back the responses
List<LinodeResponse> linodeResponses = linodeApi.execute(linodeRequests);

Available API calls

have a look at https://github.com/synapticloop/linode-api/tree/master/src/main/java/synapticloop/linode/api for the list of available API classes.

Building the Package top

*NIX/Mac OS X top

From the root of the project, simply run

./gradlew build

Windows top

./gradlew.bat build

This will compile and assemble the artefacts into the build/libs/ directory.

Note that this may also run tests (if applicable see the Testing notes)

Running the Tests top

*NIX/Mac OS X top

From the root of the project, simply run

gradle --info test

if you do not have gradle installed, try:

gradlew --info test

Windows top

From the root of the project, simply run

gradle --info test

if you do not have gradle installed, try:

./gradlew.bat --info test

The --info switch will also output logging for the tests

WARNING: These tests make calls against resources (either API calls to a service provider, or consumption of resources from a service provider) which may contribute to your limits, which may lead to a cost.

Logging - slf4j top

slf4j is the logging framework used for this project. In order to set up a logging framework with this project, sample configurations are below:

Log4j top

You will need to include dependencies for this - note that the versions may need to be updated.

Maven

<dependency>
	<groupId>org.apache.logging.log4j</groupId>
	<artifactId>log4j-slf4j-impl</artifactId>
	<version>2.5</version>
	<scope>runtime</scope>
</dependency>

<dependency>
	<groupId>org.apache.logging.log4j</groupId>
	<artifactId>log4j-core</artifactId>
	<version>2.5</version>
	<scope>runtime</scope>
</dependency>

Gradle < 2.1

dependencies {
	...
	runtime(group: 'org.apache.logging.log4j', name: 'log4j-slf4j-impl', version: '2.5', ext: 'jar')
	runtime(group: 'org.apache.logging.log4j', name: 'log4j-core', version: '2.5', ext: 'jar')
	...
}

Gradle >= 2.1

dependencies {
	...
	runtime 'org.apache.logging.log4j:log4j-slf4j-impl:2.5'
	runtime 'org.apache.logging.log4j:log4j-core:2.5'
	...
}

Setting up the logging:

A sample log4j2.xml is below:

<Configuration status="WARN">
	<Appenders>
		<Console name="Console" target="SYSTEM_OUT">
			<PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
		</Console>
	</Appenders>
	<Loggers>
		<Root level="trace">
			<AppenderRef ref="Console"/>
		</Root>
	</Loggers>
</Configuration>
