Chapter 170. JClouds Component

You can have as many of these options as you like.

jclouds:blobstore:aws-s3?operation=CamelJcloudsGet&container=mycontainer&blobName=someblob

For producer endpoint you can override all of the above URI options by passing the appropriate headers to the message.

This example will show you how you can store any message inside a blob using the jclouds component.

from("direct:start")
    .to("jclouds:blobstore:aws-s3" +
        "?operation=PUT" +
        "&container=mycontainer" +
        "&blobName=myblob");

In the above example you can override any of the URI parameters with headers on the message. Here is how the above example would look like using xml to define our route.

<route>
    <from uri="direct:start"/>
    <to uri="jclouds:blobstore:aws-s3?operation=PUT&container=mycontainer&blobName=myblob"/>
</route>

This example will show you how you can read the contnet of a blob using the jclouds component.

from("direct:start")
    .to("jclouds:blobstore:aws-s3" +
        "?operation=GET" +
        "&container=mycontainer" +
        "&blobName=myblob");

In the above example you can override any of the URI parameters with headers on the message. Here is how the above example would look like using xml to define our route.

<route>
    <from uri="direct:start"/>
    <to uri="jclouds:blobstore:aws-s3?operation=PUT&container=mycontainer&blobName=myblob"/>
</route>

This example will consume all blob that are under the specified container. The generated exchange will contain the payload of the blob as body.

    from("jclouds:blobstore:aws-s3" +
        "?container=mycontainer")
        .to("direct:next");

You can achieve the same goal by using xml, as you can see below.

<route>
    <from uri="jclouds:blobstore:aws-s3?operation=GET&container=mycontainer&blobName=myblob"/>
    <to uri="direct:next"/>
</route>

jclouds:compute:aws-ec2?operation=CamelJcloudsCreateNode&imageId=AMI_XXXXX&locationId=eu-west-1&group=mygroup

    from("jclouds:compute:aws-ec2" +
        "&operation=CamelJCloudsListImages")
        .to("direct:next");

This will create a message that will contain the list of images inside its body. You can also do the same using xml.

<route>
    <from uri="jclouds:compute:aws-ec2?operation=CamelJCloudsListImages"/>
    <to uri="direct:next"/>
</route>

    from("direct:start").
    to("jclouds:compute:aws-ec2" +
        "?operation=CamelJcloudsCreateNode" +
        "&imageId=AMI_XXXXX" +
        "&locationId=XXXXX" +
        "&group=myGroup");

This will create a new node on the cloud provider. The out message in this case will be a set of metadata that contains information about the newly created node (e.g. the ip, hostname etc). Here is the same using spring xml.

<route>
    <from uri="direct:start"/>
    <to uri="jclouds:compute:aws-ec2?operation=CamelJcloudsCreateNode&imageId=AMI_XXXXX&locationId=XXXXX&group=myGroup"/>
</route>

    from("direct:start").
    to("jclouds:compute:aws-ec2" +
        "?operation=CamelJcloudsRunScript" +
        "?nodeId=10" +
        "&user=ubuntu");

The sample above will retrieve the body of the in message, which is expected to contain the shell script to be executed. Once the script is retrieved, it will be sent to the node for execution under the specified user (in order case ubuntu). The target node is specified using its nodeId. The nodeId can be retrieved either upon the creation of the node, it will be part of the resulting metadata or by a executing a LIST_NODES operation.

Note This will require that the compute service that will be passed to the component, to be initialized with the appropriate jclouds ssh capable module (e.g. jsch or sshj).

Here is the same using spring xml.

<route>
    <from uri="direct:start"/>
    <to uri="jclouds:compute:aws-ec2?operation=CamelJcloudsListNodes&?nodeId=10&user=ubuntu"/>
</route>
