Question

我正在使用基于高山的无头镀铬：docker下的3.7图像。但是，当我使用Chrome DevTools协议截取屏幕截图时，我发现alpine无法显示除英语之外的其他语言，如下面的屏幕截图所示。

我试图将字体复制到docker image

COPY NotoSansCJKsc-Regular.otf /usr/share/fonts/

并尝试在alpine源中安装字体：

RUN apk add --no-cache bash \
ttf-ubuntu-font-family \
font-adobe-100dpi \
font-noto \
ttf-dejavu \

但所有方法都失败了。所以我的问题是阿尔卑斯支持中文？我如何使用Docker使用它？

截取屏幕截图的python代码：

import pychrome
import time
import base64

    screen_lock = threading.Lock()

在测试频道安装wqy-zenhei包将修复它。

echo @edge http://nl.alpinelinux.org/alpine/edge/testing >> /etc/apk/repositories && apk add wqy-zenhei@edge
