# Preface

This document describes the functionality provided by the Webserver plugin.

See the Deployit Reference Manual for background information on Deployit and deployment concepts.

# Overview

The webserver-plugin is a Deployit plugin that supports deployment of web content and webserver configuration to a webserver.

## Features

- Runs on Deployit 3.6 and up.
- Supports deployment to Apache and IHS webservers.
- Deploys and undeploys webserver artifacts:
  - Web content (HTML pages, images, etc.)
  - Virtual host configuration
  - Any configuration fragment
- Supports starting, stopping and restarting of webservers as control tasks.

# Requirements

- Deployit requirements

  - Deployit: version 3.6+
  - Other Deployit Plugins: None

- Infrastructural requirements

  - User credentials for accessing the webserver executables on the host running the webserver.

# Usage in Deployment Packages

The following is a manifest snippet that shows how web content and a virtual host can be included in a deployment package. The web content CI refers to a folder, html, included in the deployment package.

    Manifest-Version: 1.0
    Deployit-Package-Format-Version: 1.3
    CI-Application: PetClinic-ear
    CI-Version: 2.0

    Name: PetClinic-2.0.ear
    CI-Type: jee.Ear
    CI-Name: PetClinic

    Name: html
    CI-Type: www.WebContent

    CI-Type: www.ApacheVirtualHostSpec
    CI-host: *
    CI-port: 8080

# Using the deployables and deployeds

The following table describes which deployable/container combinations are possible.

## Deployable vs. Container table

Deployable | Container | Generated deployed
--- | --- | ---
www.WebContent | www.ApacheHttpdServer | www.PublishedWebContent
www.ApacheVirtualHostSpec | www.ApacheHttpdServer | www.ApacheVirtualHost
www.ApacheConfFragmentSpec | www.ApacheHttpdServer | www.ApacheConfFragment

The following table describes the effect a deployed has on it's container.

## Deployed Actions Table

Deployed | Actions performed for operations
--- | ---
| Create | Destroy | Modify
www.PublishedWebContent | Create target path on webserver, if needed Copy web content to target path on webserver | Delete web content from host | Delete existing web content from webserver Copy modified web content to target path on webserver
www.ApacheVirtualHost | Copy virtual host configuration to webserver | Delete virtual host configuration from webserver | Delete virtual host configuration from webserver Copy new virtual host configuration to webserver
www.ApacheConfFragment | Copy configuration fragment to webserver | Delete configuration fragment from webserver | Delete configuration fragment from webserver Copy new configuration fragment to webserver
