Snappy Ubuntu Coreがリリースされたので、Vagrant上で起動してみる。それだけの記事。

Ubuntu Snappyのイメージを探す。オフィシャルなものが２つほど見つかる。
ubuntu-15.04-snappy-core-stableというのが安定版のようなのでそちらを使うことにする。

Welcome to Ubuntu 15.04 (GNU/Linux 3.19.0-15-generic x86_64)
* Documentation: https://help.ubuntu.com/
Welcome to snappy Ubuntu Core, a transactionally updated Ubuntu.
* See https://ubuntu.com/snappy
It's a brave new world here in snappy Ubuntu Core! This machine
does not use apt-get or deb packages. Please see 'snappy --help'
for app installation and transactional updates.
apt-get はもう使わないんだぜとかいてある。 snappy --help 見ろというので確認してみることにしよう。

各コマンドのヘルプは snappy [command] --help で確認できる。
$ snappy list --help
Usage:
snappy [OPTIONS] list [list-OPTIONS]
Provides a list of all active components installed on a snappy system
If requested, the command will find out if there are updates for any of the
components and indicate that by appending a * to the date. This will be slower as it requires a round trip to the app store on the network.
The
developer information refers to non-mainline versions of a package (much like PPAs in deb-based Ubuntu). If the package is the primary version of that
package in Ubuntu then the developer info is not shown. This allows one to identify packages which have custom, non-standard versions installed. As a
special case, the “sideload” developer refers to packages installed manually on the system.
When a verbose listing is requested, information
about the channel used is displayed; which is one of alpha, beta, rc or stable, and all fields are fully expanded too. In some cases, older (inactive)
versions of snappy packages will be installed, these will be shown in the verbose output and the active version indicated with a * appended to the
name of the component.
Help Options:
-h, --help Show this help message
[list command options]
-u, --updates Show available updates (requires network)
-v, --verbose Show channel information and expand all fields
snappy search
ストアか利用可能なパッケージを探すコマンド。
$ snappy search --help
Usage:
snappy [OPTIONS] search [search-OPTIONS]
Query the store for available packages
Help Options:
-h, --help Show this help message
[search command options]
--show-all Show all available forks of a package
--show-all で全て表示してくれるっぽいので実行してみる。
$ snappy search --show-all

dockerがいるな。Docker Imageで使用するためにSnappyを使おうと思っていたけどSnappy自身もDockerのホストとして使えるのか。
他には hello-world、go-example-webserver あたりが気になったので入れてみる。
$ sudo snappy install docker

とりあえずdocker入れたのであとはどうとでもなりそうだけど、
Snappy自体がなんのこっちゃか分かってないので続きはまた今度。
