[转]AspNetCore容器化(Docker)部署(一) —— 入门

一.docker注册安装

Windows Docker Desktop https://www.docker.com/products/docker-desktop

Linux Docker CE https://docs.docker.com/install/linux/docker-ce/ubuntu/

本文使用Windows环境Linux container做演示，安装完后切换到Linux container，“Switch to Linux containers...”。

打开PowerShell查看docker版本信息

PS C:\Users\Administrator> docker --version
Docker version 18.09.2, build 6247962

PS C:\Users\Administrator> docker version

Client: Docker Engine - Community

二.创建一个.NetCore示例项目“HelloWorld”

 

1.添加Dockerfile

Visual Studio下右键点击项目 - 添加 - Docker支持 - 选择Linux OS，VS会自动生成Dockerfile文件、构建image、预热container等一系列动作，像极了docker-compose。

生成的Dockerfile文件(指令详解：https://docs.docker.com/engine/reference/builder/)

WORKDIR /src
COPY ["HelloWorld/HelloWorld.csproj", "HelloWorld/"]
RUN dotnet restore "HelloWorld/HelloWorld.csproj"
COPY . .
WORKDIR "/src/HelloWorld"
RUN dotnet build "HelloWorld.csproj" -c Release -o /app
 
FROM build AS publish
RUN dotnet publish "HelloWorld.csproj" -c Release -o /app
 
FROM base AS final
WORKDIR /app
COPY --from=publish /app .
ENTRYPOINT ["dotnet", "HelloWorld.dll"]

 

镜像

PS C:\Users\Administrator> docker images
REPOSITORY                             TAG                 IMAGE ID            CREATED             SIZE
helloworld                             dev                 30c03823dd0a        23 minutes ago      260MB
mcr.microsoft.com/dotnet/core/aspnet   2.2-stretch-slim    f6d51449c477        13 days ago         260MB
docker4w/nsenter-dockerd               latest              2f1c802f322f        7 months ago        187kB

 

容器

PS C:\Users\Administrator> docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                               NAMES
c697ab8b8b14        helloworld:dev      "tail -f /dev/null"      2 hours ago         Up 2 hours          0.0.0.0:60169->80/tcp               elegant_bardeen

 

2.下面抛开IDE，手动来生成镜像、容器、启动

首先清空环境，docker rm等下文所用到的命令行文档 https://docs.docker.com/engine/reference/commandline/rm/

PS C:\Users\Administrator> docker rm -f c697ab8b8b14
c697ab8b8b14
PS C:\Users\Administrator> docker rmi 30c03823dd0a f6d51449c477

构建Image

或者直接cd到dockerfile所在目录，然后docker build -t helloworld:v1.0 .

PS C:\Users\Administrator> docker rm -f c697ab8b8b14
c697ab8b8b14

创建容器 

-d：分离模式启动容器

--restart=always：自动重启

-p：端口映射
