Debian
在 debian Bullseye 上安裝特定版本的 NGinx
我正在使用以下 Dockerfile 建構一個 docker 容器：
FROM debian:bullseye RUN apt -y update && echo 'deb https://nginx.org/packages/debian/ bullseye nginx' >> /etc/apt/sources.list && echo 'deb-src https://nginx.org/packages/debian/ bullseye nginx' >> /etc/apt/sources.list && apt -y install gnupg2 && apt-key adv --keyserver keyserver.ubuntu.com --recv-keys ABF5BD827BD9BF62 && apt -y update && apt -y install nginx nginx-extras luarocks RUN ln -sf /dev/stdout /var/log/nginx/access.log \ && ln -sf /dev/stderr /var/log/nginx/error.log # RUN luarocks install nginx-lua-prometheus EXPOSE 80 STOPSIGNAL SIGTERM根據 NGinx 網站上的說明，我將以下兩行添加到
etc/apt/sources.list：deb https://nginx.org/packages/debian/ bullseye nginx deb-src https://nginx.org/packages/debian/ bullseye nginx並啟動安裝：
apt install -y nginx ...但是，當容器啟動時，舊版本正在執行：
# nginx -v nginx version: nginx/1.18.0似乎 nginx 是從 debian 儲存庫而不是 NGinx 安裝的。
更令人驚訝的是，NGinx 包被標記為可升級：
# apt update Hit:1 http://security.debian.org/debian-security bullseye-security InRelease Hit:2 http://deb.debian.org/debian bullseye InRelease Hit:3 http://deb.debian.org/debian bullseye-updates InRelease Hit:4 https://nginx.org/packages/debian bullseye InRelease Reading package lists... Done Building dependency tree... Done Reading state information... Done 1 package can be upgraded. Run 'apt list --upgradable' to see it. # apt list --upgradable Listing... Done nginx/stable 1.20.1-1~bullseye all [upgradable from: 1.18.0-6.1] N: There is 1 additional version. Please use the '-a' switch to see it現在，如果我嘗試升級 nginx 包，它會失敗：

man apt：通過在包名稱後面加上等號 (=) 和要選擇的包的版本，可以選擇特定版本的包進行安裝。或者，可以通過在包名稱後加上正斜杠 (/) 和代號（buster、bulseye、sid …）或套件名稱（穩定、測試、不穩定）來選擇特定版本的版本。如果需要滿足請求，這還將從此版本中選擇此版本的版本以獲取此包的依賴項。
軟體包的依賴項也可能存在問題
nginx/stable 1.20.1，但是當您嘗試安裝它時會發現。
