微服务探索之路01篇.net6.0项目本地win10系统docker到服务器liunx系统docker的贯通

本文介绍从创建 net6.0 项目运行在 windows 开发环境的 docker 然后正式部署至 liunx 服务器。

1 windows10 安装 docker

  • 下载docker-desktop
  • 双击下载后的文件直接安装一直下一步到安装成功
  • 打开 docker, 点击设置找到 Docker Engine 设置国内镜像

国内镜像地址可以在阿里云找到, 阿里云镜像加速器登录之后可以看到一个加速地址, 复制出来加入设置 docker 的配置就可以

图片里的配置 json 如下:
{ "builder": { "gc": { "defaultKeepStorage": "20GB", "enabled": true } }, "debug": false, "experimental": false, "features": { "buildkit": true }, "insecure-registries": [], "registry-mirrors": [ "加速器地址" ] }

2 用 vs2022 创建一个简单的 net6.0 项目

  • 创建项目的时候选择启用 docker,

创建完之后可以发现项目多了一个 Dockerfile 文件(文件属性改为较新则复制, 不然发布之后这个文件不会在目录里), 修改文件相关内容如下图, 避免运行时出错

图上内容最终结果为:

FROM mcr.microsoft.com/dotnet/aspnet:6.0 AS base

WORKDIR /app

EXPOSE 3100

FROM mcr.microsoft.com/dotnet/sdk:6.0 AS build

WORKDIR /src

COPY . .

ENV ASPNETCORE_URLS=http://+:3100

ENTRYPOINT ["dotnet", "WebApplication1.dll"]

  • 发布项目至文件夹, 发布完成之后文件都在 bin\Release\net6.0\publish 下面
  • 打开命令窗口, 切换至发布目录下, 执行 docker buid 生成镜像

    注意最后的空格和点是必须的
  • 执行完之后打开 docker 界面可以看到生成的镜像如下图:
  • 执行 docker run 运行镜像!

    执行后打开 docker 界面切到容器运行可以看到运行起来的容器
  • 打开浏览器访问 http://127.0.0.1:3100/weatherforecast 出现界面结果表示成功,weatherforecast 这个表示这个项目的路由如果你的项目是其他路由那就写其他的路由不是固定的

3 将镜像推送至 dockerhub

1. 打开 docker 界面登录账号 (如果没账号请先注册)

2. 要上传至镜像仓库需要打上标签, 才可以上传, 执行标签命令docker tag 镜像名:版本号 dockerhub注册时候填的ID/镜像名:版本号

3. 找到打了标签的镜像 push

4. 等到进度条走完, 可以登录 https://hub.docker.com 查看提交的镜像

4 使用 daocloud 集群部署镜像到 liunx 服务器 (daocloud 已经不能使用 2022-6-16 记录)

1. 在 liunx 服务器安装 docker 安装资源比较慢所以使用 daocloud 的加速镜像安装执行以下命令就可以

curl -sSL https://get.daocloud.io/docker | sh

2. 登录daocloud添加服务器主机, 方法在登录有一串命令复制到服务器执行就可以关联
3. 关联之后找到上一步上传的镜像打开镜像进行部署

4. 点击部署出现如下界面进行配置


5. 部署完之后查看状态是否正常

6. 用 nginx 反向代理绑定域名访问指向这个端口 (自行百度如何用 nginx)

5 liunx 部署 docker 执行下面命令

curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun

以上文件内容,（记录防止跟 daocloud 一样访问不了，访问不了的时候可以直接修改下面的内容自己做一个脚本）：

#!/bin/sh
set -e
# Docker CE for Linux installation script
#
# See https://docs.docker.com/engine/install/ for the installation steps.
#
# This script is meant for quick & easy install via:
#   $ curl -fsSL https://get.docker.com -o get-docker.sh
#   $ sh get-docker.sh
#
# For test builds (ie. release candidates):
#   $ curl -fsSL https://test.docker.com -o test-docker.sh
#   $ sh test-docker.sh
#
# NOTE: Make sure to verify the contents of the script
#       you downloaded matches the contents of install.sh
#       located at https://github.com/docker/docker-install
#       before executing.
#
# Git commit from https://github.com/docker/docker-install when
# the script was uploaded (Should only be modified by upload job):
