docker命令启动各大主流中间件、Dockerfile怎么写及docker的使用.md

Docker的使用

Command模式启动中间件实例

1. mysql volume挂载启动

• my.cnf

docker run -d --name aspnet-mysql -p 3306:3306 -v /docker/mysql/conf/my.cnf:/etc/mysql/my.cnf -v /docker/mysql/db/mysql:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=p@ssw0rd mysql/mysql-server:5.7

• 进入mysql容器

docker exec -it aspnet-mysql bash

• 认证

mysql -uroot -p

• 进入系统库mysql

use mysql;
show variables like 'character%';
select user,host from user;
update user set host='%' where user='root' and host='localhost';
grant all privileges on *.* to 'root'@'%' identified by 'p@ssw0rd' with grant option;
flush privileges;

2. mongo volume挂载启动

• 第一种方式：

docker run -d --name mongo -v /docker/mongo/conf:/data/configdb -v /docker/mongo/db:/data/db -p 27017:27017 mongo:4 --auth

• 第二种方式：

docker run -d -p 27017:27017 --name aspnet-mongo -v /docker/mongo/db:/data/db -v /docker/mongo/conf:/data/configdb  mongo

3. redis volume挂载启动

• 经过测试

docker run -d -p 6379:6379 --name redis -v /docker/redis/redis.conf:/etc/redis/redis.conf -v /docker/redis/data:/data -d redis:alpine redis-server /etc/redis/redis.conf --appendonly yes

4. elasticsearch volume挂载启动

• 经过测试

docker run -d --name es -p 9200:9200 -p 9300:9300 -v /docker/es/config:/usr/share/elasticsearch/config -v /usr/local/docker/es/data:/usr/share/elasticsearch/data -v /usr/local/docker/es/plugins:/usr/share/elasticsearch/plugins elasticsearch:6.5.0 

Dockerfile编写及镜像的构建

使用的底层镜像

底层镜像名称	标签	简介	适用程序	使用环境
microsoft/dotnet	sdk	带命令行的dotnetcore运行环境	Console	Dev
microsoft/dotnet	runtime	不包含命令行dotnetcore运行环境	Console	Dev;Prod
microsoft/dotnet	runtime-deps	自包含的dotnetcore运行环境	Console	Dev;Prod
microsoft/aspnet	sdk	带命令行的dotnetcore运行环境	WebApp	Dev
microsoft/aspnet	runtime	不带带命令行的dotnetcore运行环境	WebApp	Dev;Prod

Dockerfile编写

在应用程序*.csproj的同级目录新建文件Dockerfile

一般 最后的入口使用CMD或者ENTRYPOINT

1. 控制台应用

• 经过验证

# 开发环境
FROM microsoft/dotnet
WORKDIR /app

COPY . /app
CMD ["dotnet","run"]

# 生产环境
# 思路：隔离编译目录 /code 和构建目录 /app，编译时先行逐个拷贝各层的*csproj至/code，dotnet restore,然后拷贝所有文件dotnet 
# publish -c release -o out 生成到/code/out,接着拷贝编译后的文件至/app，依赖于runtime镜像构建应用镜像

FROM microsoft/dotnet:sdk AS build-env
WORKDIR /code

COPY *.csproj /code
RUN dotnet restore

COPY . /code
RUN dotnet publish -c release -o out

FROM microsoft/dotnet:runtime
WORKDIR /app

COPY --from=build-env /code/out /app

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

2. Web应用

   1. 单层应用的Dockerfile文件怎么写？
   • 经过测试

   from microsoft/dotnet:2.2-sdk as build-env
   workdir /code 
   
   copy Crafts.RobotEduPlat.Mvc.csproj /code
   run dotnet restore Crafts.RobotEduPlat.Mvc.csproj
   
   copy . /code
   run dotnet publish Crafts.RobotEduPlat.Mvc.csproj -c release -o /code/out
   
   from microsoft/dotnet:2.2-aspnetcore-runtime 
   workdir /app
   
   
   copy --from=build-env /code/out /app
   expose 80
   entrypoint ["dotnet","Crafts.RobotEduPlat.Mvc.dll"]
   
   

   2. 多层架构应用的Dockerfile文件怎么写？
   • 经过测试

   FROM microsoft/dotnet:sdk AS build-env
   workdir /code
   
   copy src/Services/Crafts.RobotEduPlat.Api/Crafts.RobotEduPlat.Api.csproj src/Services/Crafts.RobotEduPlat.Api/
   copy src/Services/Crafts.RobotEduPlat.App/Crafts.RobotEduPlat.App.csproj src/Services/Crafts.RobotEduPlat.App/
   copy src/Services/Crafts.RobotEduPlat.Domain/Crafts.RobotEduPlat.Domain.csproj src/Services/Crafts.RobotEduPlat.Domain/
   copy src/Services/Crafts.RobotEduPlat.Repository/Crafts.RobotEduPlat.Repository.csproj src/Services/Crafts.RobotEduPlat.Repository/
   copy src/Services/Infrastructure/Infrastructure.csproj  src/Services/Infrastructure/
   run dotnet restore src/Services/Crafts.RobotEduPlat.Api/Crafts.RobotEduPlat.Api.csproj
   
   copy . /code
   run dotnet publish src/Services/Crafts.RobotEduPlat.Api/Crafts.RobotEduPlat.Api.csproj -c release -o /code/out
   
   from microsoft/dotnet:2.2-aspnetcore-runtime 
   workdir  /app
   copy --from=build-env /code/out /app
   
   expose 5000 
   entrypoint ["dotnet","Crafts.RobotEduPlat.Api.dll"]
