!!注意!!
MicroPCFはPCF Devに名前に変わりました。 PCF Dev版の記事をこちらに書き直しました。Cloud FoundryはオープンソースなPaaSプラットフォームであり、ローカルにもPaaS環境を構築することができます。
MicroPCFは開発用にローカル環境で簡単にCloud Foundryを試すための環境です。(MicroPCFとは？や、BOSH Liteとの違いはこちらのissueを参照してください)
vagrant upだけで、ローカルに簡単にCloudFoundry環境を作ることができます。
試したのはv0.6.0です。 また、VagrantとVirtualBoxのバージョンは以下の通りです。
$ vagrant --version
Vagrant 1.8.1
$ VBoxManage --version
5.0.12r104815
セットアップ方法
$ wget https://github.com/pivotal-cf/micropcf/releases/download/v0.6.0/micropcf-v0.6.0.zip
$ unzip micropcf-v0.6.0.zip
$ cd micropcf-v0.6.0
設定可能な環境変数は以下の通りです。
MICROPCF_IP... MicroPCFのIPアドレス(デフォルトは192.168.11.11)MICROPCF_DOMAIN... MicroPCFのドメイン名(デフォルトのIPアドレスを使う場合はlocal.micropcf.io、それ以外の場合は$MICROPCF_IP.xip.io)VM_CORES... VMに割り当てるCPU数(デフォルトはホストマシンの論理コア数)VM_MEMORY... VMに割り当てるメモリ(MB)(デフォルトはホストマシンの1/4のメモリ)
192.168.11.*をすでに使っている場合は、MICROPCF_IPを設定しないと、
The specified host network collides with a non-hostonly network!
This will cause your specified IP to be inaccessible. Please change
the IP or name of your host only network so that it no longer matches that of
a bridged or non-hostonly network.
と言われます。この場合は、以下の環境変数を設定してください。
$ export MICROPCF_IP=192.168.33.10
この設定を行った場合は、この後のlocal.micropcf.ioを$MICROPCF_IP.xip.ioに読み替えてください。
以上の設定の後、vagrant upします。boxのファイルサイズがかなり大きいので初回ダウンロードは時間がかかります。

スケールアウトも前記事と同じようにできます。
ローカルでCloud Foundryを色々試したい場合に便利です。
ただし、管理コンソールはありません。
またマーケットプレイスにはv0.6.0の段階で
- MySQL
- Redis
が登録されています。これはPivotal Cloud Foundryで使えるサービスとほぼ同じもので、MicroPCFで動いたアプリがPCFでも動くことを目的としてサービスが用意されているようです。
$ cf marketplace
Getting services from marketplace in org micropcf-org / space micropcf-space as admin...
OK
service plans description
p-mysql 512mb, 1gb MySQL databases on demand
p-redis shared-vm Redis service to provide a key-value store
TIP: Use 'cf marketplace -s SERVICE' to view descriptions of individual plans of a given service.
次のバージョンでRabbitMQも使えるようになるかも？
