ubi8-init:
CMD 被設(shè)置為 /sbin/init 以默認(rèn)啟動 systemd Init 服務(wù)
包括 ps 并處理相關(guān)命令（procps-ng 軟件包）
將 SIGRTMIN+3 設(shè)置為 StopSignal,因為 ubi8-init 中的 systemd 忽略常規(guī)信號退出（SIGTERM 和 SIGKILL）,但在接收時會終止 SIGRTMIN+3
ubi8:
CMD 被設(shè)置為 /bin/bash
不包含 ps 并處理相關(guān)命令（procps-ng 軟件包）
不忽略退出的普通信號（SIGTERM 和 SIGKILL）
ubi-micro 是最小的 UBI 鏡像,它排除了軟件包管理器及其所有依賴項,它們通常包含在容器鏡像中朽肥。這可最小化基于 ubi-micro 鏡像的容器鏡像攻擊面,并適用于最小應(yīng)用程序,即使您將 UBI 標(biāo)準(zhǔn)、最小或 Init 用于其他應(yīng)用程序。沒有 Linux 發(fā)行包的容器鏡像被稱為 Distroless 容器鏡像。
