从Dockerfile创建映像 [英] Create an image from a Dockerfile

问题描述

我正在查看这样的Docerfile：

I am looking at a Docerfile like this:

FROM microsoft/aspnetcore:2.0 AS base

# Install the SSHD server
RUN apt-get update \
  && apt-get install -y --no-install-recommends openssh-server \
  && mkdir -p /run/sshd \
  && echo "root:Docker!" | chpasswd
#Copy settings file. See elsewhere to find them. 
COPY sshd_config /etc/ssh/sshd_config
COPY authorized_keys  root/.ssh/authorized_keys

# Install Visual Studio Remote Debugger
RUN apt-get install zip unzip
RUN curl -sSL https://aka.ms/getvsdbgsh | bash /dev/stdin -v latest -l ~/vsdbg

EXPOSE 2222

<我正在尝试使用此dockerfile创建映像。我怎样才能做到这一点？在过去的几个小时中，我已经阅读了许多网页此 https://odewahn.github.io/docker- jumpstart / building-images-with-dockerfiles.html ，但是由于我的研究告诉我只需要一个命令，它们似乎都使它变得过于复杂。

I am trying to create an image using this dockerfile. How can I do this? I have read many webpages over the last few hours e.g. this one https://odewahn.github.io/docker-jumpstart/building-images-with-dockerfiles.html, however they all seem to overcomplicate it as my research is telling me that there is only one command needed.

推荐答案

由于拥有Docker文件，因此您需要执行4个附加步骤：

Since you have a Docker file, you are required to do 4 additional steps:

1. docker build -t< app-name> 。：构建映像

docker映像：检查您的映像

docker run -d -p 2222：8080 myapp ：运行您的图片

docker ps ：检查正在运行的docker image

docker ps : Check running docker image

请参阅 Docker文档。以获取更多详细信息
