Performs a hot deployment of a Deployable
- Local Deployer: A local deployer deploys in a locally installed container. Usually, local deployers use the file system to perform the deployment by copying the deployable to a container-specific target directory.
- Remote Deployer: A remote deployer is used to deploy to a container that can be on the same machine or on some remote machine. Deploying remotely requires passing information such as username and password of the user to use for deploying, etc. These information are passed using a Runtime Configuration.
- Local Deployer — Performs a hot deployment of a Deployable on a locally installed container
- Remote Deployer — Performs a hot deployment of a Deployable on a container running on a remote machine
Example using the Java API
To instantiate a
Deployer you need to know its class name. A
Deployer is specific to a container (you can find the class names on the container page listing all containers).
The deployment is done using one of the
Deployer.deploy(...) APIs. Some
deploy(...) signatures accept a
DeployableMonitor which is used to wait till the container has not finished deploying. Cargo currently offers a
URLDeployableMonitor which waits by polling a provided URL (see below in the example). Whent the URL becomes available the monitor considers that the
Deployable is fully deployed. In the future, Cargo will provide other
DeployableMonitor such as a
Example without using a DeployableMonitor
Hot-deploying a WAR on Resin 3.0.9 without waiting for the deployment to finish:
Please note that the
Deployer.deploy() method call does not wait for the
Deployable to be fully deployed before returning.
Example using a URLDeployableMonitor
Hot-deploying an WAR on Resin 3.0.9 and waiting for the deployment to finish:
http://server:port/some/url must point to a resource that is serviced by the
Deployable being deployed.
Example using the Ant tasks
Starting from CARGO version 1.1.0, the CARGO ANT tasks gained support for remote deployers. Here's a full example showing how to deploy a WAR to a remote Tomcat 6.x container.
For more details, please check the example in the Remote Container section for the ANT tasks The. ANT tasks support the deployer actions
Please see the Deploying to a running container for a concrete example and the Maven2 Plugin Reference Guide's
<deployer> section for full documentation.
