.net6 docker部署，以及问题解决（附Dokerfile）

搭建仓库，发布配置

docker搭建私有仓库

参考上文，搭建好私有仓库，成功访问http://127.0.0.1:5000/v2/_catalog之后:

1. 在VS右键 => 添加 => Docker支持 => 选择Linux，即可自动添加Dokerfile
2. 在VS右键发布 => Docker容器注册表 => 其他Docker容器注册表 => 注册表URL：http://localhost:5000
3. 发布配置：
   

部署模式选择独立或者框架依赖都可以，如果选择框架依赖，那么启动项目时，需要运行.net6的容器。

启动容器的问题以及相应解决方法

1. System.Drawing.Common is not supported on non-Windows platforms.

仅在 Windows 上支持 System.Drawing.Common
简单说就是有两种解决方法：

1. 将引用System.Drawing.Common的代码改为其他类库
2. 新增一个runtimeconfig.template.json 模板文件：
   

2. System.TypeInitializationException: The type initializer for \'Gdip\' threw an exception.

System.TypeInitializationException: The type initializer for \'Gdip\' threw an exception.
System.DllNotFoundException: Unable to load shared library \'libgdiplus\' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: liblibgdiplus: cannot open shared object file: No such file or directory

需要在容器中安装libgdiplus，可在dockerfile中添加如下代码：

WORKDIR /etc/apt
# 备份
RUN mkdir sources.list.backup
RUN cp sources.list ./sources.list.backup
# 以覆盖+追加的方式替换掉sources.list文件(解决下载慢问题)
RUN echo \'deb https://mirrors.aliyun.com/debian bullseye main\'>sources.list
RUN echo \'deb https://mirrors.aliyun.com/debian-security bullseye-security main\'>>sources.list
RUN echo \'deb https://mirrors.aliyun.com/debian bullseye-updates main\'>>sources.list
#RUN cat sources.list
RUN apt-get update -y
RUN apt-get install -y libgdiplus

3. Cannot find any fonts in specified font sources.

1. 到windows系统的C://windows/Fonts目录下寻找字体，将找到的字体和Dockerfile文件放在同一级目录下
2. 在dockerfile中添加如下代码：

COPY ["src/myProject/simkai.ttf", "/usr/share/fonts/simkai.ttf"]  
COPY ["src/myProject/SimSun.ttf", "/usr/share/fonts/SimSun.ttf"]

4. RedisConnectionException: It was not possible to connect to the redis server(s).

修改redis.windows-service.conf,增加ip地址配置（192.168.5.22为主机的ip）：

bind 127.0.0.1 192.168.5.22
