docker - alpine:3.14 docker libtls.so.20 冲突

问题描述

所以我在使用来自 alpine 的最新 docker build 时遇到了错误。alpine:3.14.0 大约在一天前发布，并试图安装 libressl 和 libressl-dev，但似乎都失败并出现以下错误。我目前的工作是使用 alpine:3.12.0 构建，因为 3.12.0 似乎没有安装 libretls。虽然我想知道如何解决这个问题。我试图删除 libretls，但没有奏效（下面也有错误）。谢谢

解决方案

这是上游问题。暂时降级到 alpine 3.13 直到问题得到解决。通常 docker 图像支持固定的高山版本（感谢 MrGlass 评论）。例如

python:3-alpine -> python:3-alpine3.13
php:7.4-fpm-alpine -> php:7.4-fpm-alpine3.13
