Vagrant 1.4.1でCentOS上でdockerを走らせてみる

Vagrantが1.4.1になって、Redhat、CentOSでもdockerのproviderが動くようになったということで、試してみた。

結果

とりあえず動かしてみることは簡単にできた。

Vagrantfileを作る

実行

vagrant up

こんな感じでdockerのコンテナができていることを確認

[otahi@otahiair test-docker-vagrant]$ vagrant up       
Bringing machine 'default' up with 'virtualbox' provider...
[default] Box 'centos65' was not found. Fetching box from specified URL for
the provider 'virtualbox'. Note that if the URL does not have
a box for this provider, you should interrupt Vagrant now and add
the box yourself. Otherwise Vagrant will attempt to download the
full box prior to discovering this error.
Downloading box from URL: https://github.com/2creatives/vagrant-centos/releases/download/v6.5.1/centos65-x86_64-20131205.box

[default] The guest additions on this VM do not match the installed version of
VirtualBox! In most cases this is fine, but in rare cases it can
cause things such as shared folders to not work properly. If you see
shared folder errors, please make sure the guest additions within the
virtual machine match the version of VirtualBox you have installed on
your host and reload your VM.
