jail(iocage)で、なろう>mobiその１

以前の環境はぐちゃぐちゃだったので、OS更新で仕切りなおして、今度はjailですみ分けてみようかと。
前にqjailを試したことがあるけどなんかしっくりこなかったなーとか思ってぐぐってたら、iocageの紹介が。
FreeBSDでiocageを使ってJailを管理する - Qiita
FreeNAS由来の管理ツール？というわけで、これ行ってみる。

# pkg install py37-iocage
# iocage activate ztank

あら、なんか怒られた。activate対象でないpoolを、deactivateしようとしてる？
HDD更新の時に、以前のzpool(zroot)をreadonlyでimportしてたので書き込めなかったっぽい。zpool export zroot で外して再チャレンジ。

# iocage activate ztank
# mount -t fdescfs null /dev/fd
# iocage list
Creating ztank/iocage
Creating ztank/iocage/download
Creating ztank/iocage/images
Creating ztank/iocage/jails
Creating ztank/iocage/log
Creating ztank/iocage/releases
Creating ztank/iocage/templates
Please set a mountpoint on ztank/iocage

あら、また何か言われてる。ぐぐると、ztank を moupoint=none で作っているせい？ということで、再チャレンジ。
narou.rbを動かす環境なので、jail名はnarouで。

# zfs set mountpoint=/iocage ztank/iocage
# iocage create -n narou -r 12.1-RELEASE
