*{component-header}*

The AWS2 EC2 component supports the ability to create, run, start, stop and terminate
https://aws.amazon.com/ec2/[AWS EC2] instances.

Prerequisites

You must have a valid Amazon Web Services developer account, and be
signed up to use Amazon EC2. More information is available at
https://aws.amazon.com/ec2/[Amazon EC2].

[NOTE]
====
The AWS2 EC2 component is not supported in OSGI

== URI Format

[source,java]
-------------------------
aws2-ec2://label[?options]
-------------------------

You can append query options to the URI in the following format,
?options=value&option2=value&...

== URI Options


// component options: START
The AWS 2 Elastic Compute Cloud (EC2) component supports 14 options, which are listed below.



[width="100%",cols="2,5,^1,2",options="header"]
|===
| Name | Description | Default | Type
| *autoDiscoverClient* (common) | Setting the autoDiscoverClient mechanism, if true, the component will look for a client instance in the registry automatically otherwise it will skip that checking. | true | boolean
| *accessKey* (producer) | Amazon AWS Access Key |  | String
| *amazonEc2Client* (producer) | To use a existing configured AmazonEC2Client as client |  | Ec2Client
| *configuration* (producer) | The component configuration |  | AWS2EC2Configuration
| *lazyStartProducer* (producer) | Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel's routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing. | false | boolean
| *operation* (producer) | *Required* The operation to perform. It can be createAndRunInstances, startInstances, stopInstances, terminateInstances, describeInstances, describeInstancesStatus, rebootInstances, monitorInstances, unmonitorInstances, createTags or deleteTags. The value can be one of: createAndRunInstances, startInstances, stopInstances, terminateInstances, describeInstances, describeInstancesStatus, rebootInstances, monitorInstances, unmonitorInstances, createTags, deleteTags |  | AWS2EC2Operations
| *pojoRequest* (producer) | If we want to use a POJO request as body or not | false | boolean
| *proxyHost* (producer) | To define a proxy host when instantiating the EC2 client |  | String
| *proxyPort* (producer) | To define a proxy port when instantiating the EC2 client |  | Integer
| *proxyProtocol* (producer) | To define a proxy protocol when instantiating the EC2 client. The value can be one of: HTTP, HTTPS | HTTPS | Protocol
| *region* (producer) | The region in which EC2 client needs to work. When using this parameter, the configuration will expect the lowercase name of the region (for example ap-east-1) You'll need to use the name Region.EU_WEST_1.id() |  | String
| *secretKey* (producer) | Amazon AWS Secret Key |  | String
| *trustAllCertificates* (producer) | If we want to trust all certificates in case of overriding the endpoint | false | boolean
| *basicPropertyBinding* (advanced) | Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities | false | boolean
|===

Required EC2 component options

You have to provide the amazonEc2Client in the
Registry or your accessKey and secretKey to access
the https://aws.amazon.com/ec2/[Amazon EC2] service.

- startInstances
- stopInstances
- terminateInstances

- deleteTags

== Producer Examples

- createAndRunInstances: this operation will create an EC2 instance and run it

[source,java]
--------------------------------------------------------------------------------
from("direct:createAndRun")
     .setHeader(EC2Constants.IMAGE_ID, constant("ami-fd65ba94"))
     .setHeader(EC2Constants.INSTANCE_TYPE, constant(InstanceType.T2Micro))
     .setHeader(EC2Constants.INSTANCE_MIN_COUNT, constant("1"))
     .setHeader(EC2Constants.INSTANCE_MAX_COUNT, constant("1"))
     .to("aws2-ec2://TestDomain?accessKey=xxxx&secretKey=xxxx&operation=createAndRunInstances");
--------------------------------------------------------------------------------

- startInstances: this operation will start a list of EC2 instances

[source,java]
--------------------------------------------------------------------------------
from("direct:start")
     .process(new Processor() {
            @Override
            public void process(Exchange exchange) throws Exception {
                Collection<String> l = new ArrayList<>();
                l.add("myinstance");
                exchange.getIn().setHeader(AWS2EC2Constants.INSTANCES_IDS, l);
            }
        })
     .to("aws2-ec2://TestDomain?accessKey=xxxx&secretKey=xxxx&operation=startInstances");
--------------------------------------------------------------------------------

- stopInstances: this operation will stop a list of EC2 instances

[source,java]
--------------------------------------------------------------------------------
from("direct:stop")
     .process(new Processor() {
            @Override
            public void process(Exchange exchange) throws Exception {
                Collection<String> l = new ArrayList<>();
                l.add("myinstance");
                exchange.getIn().setHeader(AWS2EC2Constants.INSTANCES_IDS, l);
            }
        })
     .to("aws2-ec2://TestDomain?accessKey=xxxx&secretKey=xxxx&operation=stopInstances");
--------------------------------------------------------------------------------

- terminateInstances: this operation will terminate a list of EC2 instances

[source,java]
--------------------------------------------------------------------------------
from("direct:stop")
     .process(new Processor() {
            @Override
            public void process(Exchange exchange) throws Exception {
                Collection<String> l = new ArrayList<>();
                l.add("myinstance");
                exchange.getIn().setHeader(AWS2EC2Constants.INSTANCES_IDS, l);
            }
        })
     .to("aws2-ec2://TestDomain?accessKey=xxxx&secretKey=xxxx&operation=terminateInstances");
--------------------------------------------------------------------------------

== Automatic detection of Ec2Client client in registry

The component is capable of detecting the presence of an Ec2Client bean into the registry.
If it's the only instance of that type it will be used as client and you won't have to define it as uri parameter.
This may be really useful for smarter configuration of the endpoint.

== Using a POJO as body

Sometimes build an AWS Request can be complex, because of multiple options. We introduce the possibility to use a POJO as body.
In AWS EC2 there are multiple operations you can submit, as an example for Create and run an instance, you can do something like:

------------------------------------------------------------------------------------------------------
from("direct:start")
  .setBody(RunInstancesRequest.builder().imageId("test-1").instanceType(InstanceType.T2_MICRO).build())
  .to("aws2-ec2://TestDomain?accessKey=xxxx&secretKey=xxxx&operation=createAndRunInstances&pojoRequest=true");
------------------------------------------------------------------------------------------------------

In this way you'll pass the request directly without the need of passing headers and options specifically related to this operation.

== Dependencies

Maven users will need to add the following dependency to their pom.xml.

*pom.xml*

[source,xml]
---------------------------------------
<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-aws2-ec2</artifactId>
    <version>${camel-version}</version>
</dependency>
---------------------------------------

where `$\{camel-version\}` must be replaced by the actual version of Camel.
