StreamのEOL †

RedHatのFull Supportに準じるようだ

CentOS Stream 8 EOL: 2024-05-31
- EOL変更前のCentOS 8は2029-05-31だったのを考えるとかなり短く感じる。CentOS 7より短い

CentOS 7 EOL: 2024-06-30

移行 †

Q7: How do I migrate my CentOS Linux 8 installation to CentOS Stream?

CentOS 8からCentOS Stream 8へ移行

# 変更前
cat /etc/redhat-release
CentOS Linux release 8.2.2004 (Core)

# Streamへ切替
sudo dnf install centos-release-stream
sudo dnf swap centos-{linux,stream}-repos
sudo dnf distro-sync
...
Total download size: 464 M # ソフトウェア、開発ツールを入れていた場合

# 変更後
cat /etc/redhat-release
CentOS Stream release 8

# kernelが更新されたので再起動
sudo reboot

移行の懸念点 †

Q: Stream 8から9等へ勝手にアップグレードされないか？
A: されない。

Q: CentOS 8.0, 8.1, ...みたいなマイナーバージョンの固定はできる？
A: できない。ここが継続的デリバリー？

Q: CentOS 8からStream 8への移行は？
A: コマンドが用意されている。yum repoとパッケージが変わるので、商用環境は検証が必要。

Q: EC2のAMIある？
A: 2020-12-16時点はまだ無い。CentOS 8のAMIはあるので、自分で移行コマンド実行か。
