OpenShift 4.7 UPI install on bare metal

7
Last updated at Posted at 2021-04-03

概要

おうちKubernetes・OpenShift勢の皆さん、こんにちは！！
OpenShift 4.7 のベアメタルへのUPIインストールを実施しましたので、ポイントをご紹介します。

4.6をインストールした時と同じ構成、手順でインストールができましたので、以下記事もご参照ください。

OpenShift 4.11 以降については以下記事もご参照ください。

4.7.4インストール時にバグを踏んでしまいましたので、本記事では、その回避策について記載します。

なお、その後 4.7.16をインストールした際には、この事象は発生しませんでしたので、bugfixされている可能性があります。

現象

authentication, console, monitoringなど、複数のclusteroperatorsが立ち上がりませんでした。

(抜粋)
[root@bastion ocp]# ./oc get clusteroperators

Issue

以下のIssueがありました。

以下のような報告が寄せられています。

  • 仮想マシンのハードウェア互換性が13より大きい場合に発生する。13にすると解消した。
  • networkType を OVNKubernetes にすると解消する

回避策

私はVMのハードウェア互換性を13に下げることで4.7.4をインストールすることができることを確認しました。

vmware の場合は以下をご参照ください。VM作成時に互換性にESXi 6.5 仮想マシンを指定すると良いです。
仮想マシンのハードウェア バージョン (1003746)

ただ、この方法はVM自体を作り直す必要もあるので個人的にはおすすめしません。
以下のRed Hat 公開情報にWORKAROUNDな回避策がいくつか挙げられていますので、公式情報としては以下を参照するのが良いと思います。

[Bug] Openshift-apiserver cluster-operator goes unavailable during cluster upgrade from RHOCP 4.6 to 4.7 - Red Hat Customer Portal

また、UPI/IPIインストール界隈で情報発信されているRed Hat Solutions Architectの田中さんより、本件は4.7.5で修正されていると教えていただきましたので、可能であれば4.7.5以降を使用するのが良いと思います(田中さんありがとうございます！)。

その際の会話については、以下ツイートに続くリプライをご参照ください。

OpenShift 4.7のインストールのポイントについてご参考になりましたら幸いです。
