About WAR contexts

Many containers have their specific files for redefining context roots (Tomcat has context.xml, JBoss has jboss-web.xml, etc.). If your WAR has such a file, the server will most probably use the context root defined in that file instead of the one you specify using the CARGO deployer.

Daemon configuration

The Cargo Daemon is a Web-based application that uses the Cargo API to configure, start and stop containers on a remote machine. The daemon is meant to be listening 24/7, to allow users to deploy new containers and web applications at their command. For more information, please read: Cargo Daemon.

Container configuration for the Daemon

For the Ant tasks, the "daemonized server" is actually a local container with a hostname that points to a remote machine. This implies that:

  • You should not set the container type to a remote container nor add any remote deployers to the configuration; but instead define the container as a local container (with either a standalone or existing configuration)
  • When you define the home paths for the container and the configuration, remember these paths are for the machine where the Daemon is running (and, preferably, use absolute paths)

When you call daemon-start, the Ant tasks will do the following:

  • If an installer is defined:
    • Download the archive locally
    • Send the archive over to the machine running the Daemon
    • Instruct the Daemon to extract the archive
  • If a standalone local configuration is defined, instruct the Daemon to create it
  • In all cases:
  • Finally, instruct the Daemon to start the container
