          # Cloud Foundry TomEE Buildpack

The `tomee-buildpack` is a [Cloud Foundry][] buildpack for running JVM-based applications.  It is designed to run many JVM-based applications ([Grails][], [Groovy][], Java Main, [Play Framework][], [Spring Boot][], and Java EE Web Profile) with no additional configuration, but supports configuration of the standard components, and extension to add custom components.

This buildpack has been customised to use TomEE. The standard Java Buildpack currently uses Tomcat.

## Usage

To use this buildpack specify the URI of the repository when pushing an application to Cloud Foundry:

```bash

$ cf push  -p  -b https://github.com/cloudfoundry-community/tomee-buildpack.git

```

## Examples

The following are _very_ simple examples for deploying the artifact types that we support.

* [Embedded web server](docs/example-embedded-web-server.md)

* [Grails](docs/example-grails.md)

* [Groovy](docs/example-groovy.md)

* [Java Main](docs/example-java_main.md)

* [Play Framework](docs/example-play_framework.md)

* [Servlet](docs/example-servlet.md)

* [Spring Boot CLI](docs/example-spring_boot_cli.md)

## Configuration and Extension

The buildpack default configuration can be overridden with an environment variable matching the configuration file you wish to override minus the `.yml` extension and with a prefix of `JBP_CONFIG`. It is not possible to add new configuration properties and properties with `nil` or empty values will be ignored by the buildpack (in this case you will have to extend the buildpack, see below). The value of the variable should be valid inline yaml, referred to as "flow style" in the yaml spec ([Wikipedia][] has a good description of this yaml syntax). For example, to change the default version of Java to 11 and adjust the memory heuristics apply this environment variable to the application.

```bash

$ cf set-env my-application JBP_CONFIG_OPEN_JDK_JRE '{ jre: { version: 11.+ }, memory_calculator: { stack_threads: 25 } }'

```

If the key or value contains a special character such as `:` it should be escaped with double quotes. For example, to change the default repository path for the buildpack.

```bash

$ cf set-env my-application JBP_CONFIG_REPOSITORY '{ default_repository_root: "http://repo.example.io" }'

```

If the key or value contains an environment variable that you want to bind at runtime you need to escape it from your shell. For example, to add command line arguments containing an environment variable to a [Java Main](docs/container-java_main.md) application.

```bash

$ cf set-env my-application JBP_CONFIG_JAVA_MAIN '{ arguments: "--server.port=9090 --foo=bar" }'

```

An example of configuration is to specify a `javaagent` that is packaged within an application.

```bash

$ cf set-env my-application JAVA_OPTS '-javaagent:app/META-INF/myagent.jar -Dmyagent.config_file=app/META-INF/my_agent.conf'

```

Environment variable can also be specified in the applications `manifest` file. For example, to specify an environment variable in an applications manifest file that disables Auto-reconfiguration.

```bash

env:

  JBP_CONFIG_SPRING_AUTO_RECONFIGURATION: '{ enabled: false }'

```

This final example shows how to change the version of TomEE that is used by the buildpack with an environment variable specified in the applications manifest file.

```bash

env:

  JBP_CONFIG_TOMEE: '{ tomee: { version: 1.7.+ } }'

```

See the [Environment Variables][] documentation for more information.

To learn how to configure various properties of the buildpack, follow the "Configuration" links below.

The buildpack supports extension through the use of Git repository forking. The easiest way to accomplish this is to use [GitHub's forking functionality][] to create a copy of this repository.  Make the required extension changes in the copy of the repository. Then specify the URL of the new repository when pushing Cloud Foundry applications. If the modifications are generally applicable to the Cloud Foundry community, please submit a [pull request][] with the changes. More information on extending the buildpack is available [here](docs/extending.md).

## Building Packages

The buildpack can be packaged up so that it can be uploaded to Cloud Foundry using the `cf create-buildpack` and `cf update-buildpack` commands.  In order to create these packages, the rake `package` task is used.

Note that this process is not currently supported on Windows. It is possible it will work, but it is not tested, and no additional functionality has been added to make it work.

### Online Package

The online package is a version of the buildpack that is as minimal as possible and is configured to connect to the network for all dependencies.  This package is about 50K in size.  To create the online package, run:

```bash

$ bundle install

$ bundle exec rake clean package

...

Creating build/tomee-buildpack-cfd6b17.zip

```

### Offline Package

The offline package is a version of the buildpack designed to run without access to a network.  It packages the latest version of each dependency (as configured in the [`config/` directory][]) and [disables `remote_downloads`][]. This package is about 180M in size.  To create the offline package, use the `OFFLINE=true` argument:

To pin the version of dependencies used by the buildpack to the ones currently resolvable use the `PINNED=true` argument. This will update the [`config/` directory][] to contain exact version of each dependency instead of version ranges.

```bash

$ bundle install

$ bundle exec rake clean package OFFLINE=true PINNED=true

...

Creating build/tomee-buildpack-offline-cfd6b17.zip

```

### Package Versioning

Keeping track of different versions of the buildpack can be difficult.  To help with this, the rake `package` task puts a version discriminator in the name of the created package file.  The default value for this discriminator is the current Git hash (e.g. `cfd6b17`).  To change the version when creating a package, use the `VERSION=` argument:

```bash

$ bundle install

$ bundle exec rake clean package VERSION=2.1

...

Creating build/tomee-buildpack-2.1.zip

```

## Running Tests

To run the tests, do the following:

```bash

$ bundle install

$ bundle exec rake

```
