我想在我的容器中安装nginx(然后是nodejs).我在nginx /文件夹中有自己的nginx配置文件:
# --- Release with Alpine ----
FROM phusion/baseimage:0.10.1
# Create app directory
WORKDIR /app
RUN apt-get update \
&& apt-get -y install nginx
RUN ls /etc/nginx
COPY nginx/nginx.conf /etc/nginx/nginx.conf
RUN ls /etc/nginx
RUN ls /etc/nginx/sites-enabled
RUN rm /etc/nginx/sites-enabled/default
COPY nginx/serverlogic /etc/nginx/sites-enabled/serverlogic
RUN ls /etc/nginx/sites-enabled
RUN nginx -s reload
RUN echo "$PWD FINALFINALFINAL" && ls
EXPOSE 8080

但我得到一个错误就是RUN nginx -s reload:"nginx:[error] open()"/ run/nginx.pid"失败(2:没有这样的文件或目录)".那是什么?
ps是否在安装了ubuntu,node.js和nginx的docker hub上有一些映像?为简单起见,我想将它们放在一个容器中.
我真的无法理解为什么,在这个例子中,这个类定义了两个GetEnumerator方法:一个显式实现接口,另一个隐式地实现接口.所以为什么?
class FormattedAddresses : IEnumerable<string>
{
private List<string> internalList = new List<string>();
public IEnumerator<string> GetEnumerator()
{
return internalList.GetEnumerator();
}
System.Collections.IEnumerator System.Collections.IEnumerable.GetEnumerator()
{
return internalList.GetEnumerator();
}
public void Add(string firstname, string lastname,
string street, string city,
string state, string zipcode)
{
internalList.Add($@"{firstname} {lastname} {street} {city}, {state} {zipcode}");
}
}
Run Code Online (Sandbox Code Playgroud) Is there a way to make a class return one of its fields by default like that:
public class TestClass
{
public string something;
}
TestClass test = new TestClass();
test = "alpha"; // "alpha" string is assigned to "something"
Console.Write(test); // test returns "alpha" string from "something"

How to make this work?
我是bash脚本的新手,所以我不能真正理解下面这行:
[[ -f /.dockerenv ]] && echo -e "Host *\n\tStrictHostKeyChecking no\n\n" > ~/.ssh/config

这个双方括号是我猜的if语句.我知道我们将"Host*\n\tStrictHostKeyChecking no \n \n"转换为配置文件,但那里的其他内容是什么.一些文档或新手教程非常感谢.提前致谢!
