NetBoxの機能でまだリリースはされていないけどfeatureブランチには実装済みの新しい機能を試してみたい場合、feature版のコンテナイメージは用意されてないためOS上に素で構築する必要があるが、それよりはfeature版コンテナイメージを手元でビルドした方が楽なのでは？と思って試してみた。
なお、試してみるとコンテナ版のビルドスクリプトはfeature版には対応していないため、実装の差異がある場合は手直しが必要*1。
以下は時期バージョンの2.11のリリースノート。
環境
[zaki@cloud-dev netbox-docker (release)]$ docker-compose --version docker-compose version 1.28.6, build 5db8d86f [zaki@cloud-dev netbox-docker (release)]$ docker --version Docker version 20.10.5, build 55c4c88
準備
Docker Compose版のリポジトリをcloneする。
$ git clone https://github.com/netbox-community/netbox-docker.git $ cd netbox-docker/
NetBoxコンテナイメージをビルドするには、付属のbuild.shを使うと簡単にビルドできる。
イメージのbuild
ビルドスクリプトの使い方は--helpを指定して確認できる。
$ ./build.sh --help ▶️ ./build.sh --help Usage: ./build.sh <branch> [--push|--push-only]
ブランチ名を引数に実行すれば、そのブランチのソースを使ってコンテナイメージがビルドされる。
デフォルトはビルドのみで、(試してないけど)--pushも付与すれば、おそらくDocker Hubへpushされる(未確認。デフォルトではnetboxcommunityリポジトリになるので個人環境では変更が必要かも)。
というわけで、NetBoxのfeatureブランチをビルドするには以下の通り。
$ ./build.sh feature
実行すると .netboxディレクトリにNetBox本体のリポジトリがcloneされビルド処理が始まる。
ビルド中はステージごとの処理時間がログの右側に表示されるのでtimeは付けなくていいかも。手元の環境(i7のESXiの上の4vCPUs RAM8GBのVM)では約10分必要だった。
あとは、実行ユーザー権限でDockerが使用可能であること。
ビルドログはこんな感じ。

エラーになっている。
先に答えを書くと、NetBox本体はfeatureブランチを今回対象としているけど、イメージビルドに使っているNetBox Dockerはfeatureブランチは存在しないのでデフォルトのreleaseブランチを使っているので、実装の差異があるとそこでエラーが発生する。
NetBox Dockerのコードを本体のfeatureブランチの内容に合わせる
以下は2021.04.03 11時(JST)時点での修正ポイント。
最初はfeatureブランチの内容が実装されてないから実装されるまで待とうかなーと思ったけど、あきらめきれずにソースを追ってみる。
(最近こんなのばっかだな)
最初に見るエラーの内容は以下。
Running the startup script /opt/netbox/startup_scripts/075_rack_groups.py : : ImportError: cannot import name 'RackGroup' from 'dcim.models' (/opt/netbox/netbox/dcim/models/__init__.py)
エラー発生個所のコードを確認すると、featureブランチはLocationになってる。
masterやdevelopだとRackGroupになっている。
そして、実行中スクリプトの075_rack_groups.pyのあるnetbox-dockerのリリースブランチでは、RackGroupを参照してる、と。
ということで、startup_scripts以下で RackGroup を参照しているところを Location に変更すれば一歩進める(少なくともimportはうまくいく)と予測が立つ。
ただ、パッケージ名変更だけで動くのかというとそれはあやしいのでもうblameをチェックすると、以下のissueで「名前の変更」が行われたことが確認できる。
変更点は以下。
目grepと脳内インタプリタでざっと見た感じでは、netbox-docker側のスクリプトもリネームでとりあえず大丈夫そうなので、startup_scripts内で参照しているRackGroupをLocationに変更してやる。
以下の通り。

変更が済んだら一度down --volumeでボリューム含めて全て削除(これはトラブル防止のために環境をクリアにするという趣旨)し、再度デプロイする。

この通り、featureブランチで開発されている2.11の表示になっている。(リリース版は現在2.10)
2.11のリリースノートはこちら
#5451 - Add support for multiple-selection custom fields
たとえばカスタムフィールドの「multi-select」とかがサポートされるようになっている。 画面右上Adminメニューの「Custom fields」で、以下のように項目が追加されているのを確認できる。
v2.11
以下はv2.10の場合
まとめ
featureブランチの内容でも手元でイメージビルドすればDocker Composeを使ってNetBoxをデプロイできることを確認できた。
ただし実装の内容(次期バージョンと現バージョンの実装の差異)によっては修正が必要。
なので、「構築は楽だけどこれでまぁ大丈夫かな？」くらいだろうか。。
今回は露見してないけど「全くの新しいパッケージimportが必要」なパターンであればデプロイのタイミングではエラーにならずに画面から参照しようとするとランタイムエラーになる、というパターンもあるかもしれないので注意。
用途としては「壊して作り直す」が容易なコンテナのメリットを活かせるので、新機能を確認するための環境の用意の手段の一つとして、やりかたをチェックしておくと良いと思う。
*1:あくまで2021.04.03時点の2.11バージョンの場合
