Estoy construyendo un contenedor acoplable con el siguiente Dockerfile:
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
Según las instrucciones del sitio NGinx, agrego las dos líneas siguientes a etc/apt/sources.list:
deb https://nginx.org/packages/debian/ bullseye nginx
deb-src https://nginx.org/packages/debian/ bullseye nginx
y lanzar la instalación:apt install -y nginx ...
Sin embargo, cuando se lanza el contenedor, unviejoLa versión se está ejecutando:
# nginx -v
nginx version: nginx/1.18.0
Parece que nginx se instala desde el repositorio de Debian en lugar del de NGinx.
Aún más sorprendente es que el paquete NGinx está marcado como actualizable:
# 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

E: Broken packages
Mi pregunta es la siguiente: ¿cómo instalar la última versión (nginx/stable 1.20.1) directamente desde el repositorio de NGinx?
Respuesta1
De man apt:
Se puede seleccionar una versión específica de un paquete para su instalación siguiendo el nombre del paquete con un igual (=) y la versión del paquete a seleccionar. Alternativamente, se puede seleccionar la versión de una versión específica siguiendo el nombre del paquete con una barra diagonal (/) y el nombre en clave (buster, bullseye, sid...) o el nombre de la suite (estable, de prueba, inestable). Esto también seleccionará versiones de esta versión para las dependencias de este paquete si es necesario para satisfacer la solicitud.
Potencialmente también hay problemas con las dependencias del nginx/stable 1.20.1paquete, pero lo descubrirás cuando intentes instalarlo.
