持续交付一:从开发到上线的环境
团队开发中,开发,测试,预发布,生产,不同的角色工作在不同的环境中,不同的环境有不同的作用(有些公司的环境更多,按照自己的交付流程设计),当然不同的环境,配置也不能相同,特别生产数据是隔离的。那asp.net core怎么来对应呢?
asp.net core为了支持不同的环境,可以把配置文件分为设置成appsettings.json,appsettings.Staging.json,appsettings.QA.json,appsettings.Development.json,配置文件中,可以放不同的配置项。
常见的不同环境配置项:
1、数据库链接字符串
2、外接存存储
3、三方接口url
4、本服务对外端口
5、区分不同环境的标准信息等
下面是三个环境的appsettings文件
Production:appsettings.json
{
"urls": "https://*:5001;http://*:5000",
"Logging": {
"LogLevel": {
"Default": "Information",
"Microsoft": "Warning",
"Microsoft.Hosting.Lifetime": "Information"
}
},
"ConnectionStrings": {
"DefaultConnectionString": "server=123.1.1.1;database=ab_db;uid=sa;pwd=!fuzamimi20;"
},
"AllowedHosts": "*"
}
Staging:appsettings.Staging.json
{
"urls": "https://*:7001;http://*:7000",
"Logging": {
"LogLevel": {
"Default": "Information",
"Microsoft": "Warning",
"Microsoft.Hosting.Lifetime": "Information"
}
},
"ConnectionStrings": {
"DefaultConnectionString": "server=123.1.1.2;database=ab_db;uid=sa;pwd=sa;"
}
}
Development:appsettings.Development.json
{
"urls": "https://*:8001;http://*:8000",
"Logging": {
"LogLevel": {
"Default": "Information",
"Microsoft": "Warning",
"Microsoft.Hosting.Lifetime": "Information"
}
},
"ConnectionStrings": {
"DefaultConnectionString": "server=123.1.1.4;database=ab_db;uid=sa;pwd=sa;"
}
}
Development:appsettings.Development.json
{
"urls": "https://*:9001;http://*:9000",
"Logging": {
"LogLevel": {
"Default": "Information",
"Microsoft": "Warning",
"Microsoft.Hosting.Lifetime": "Information"
}
},
"ConnectionStrings": {
"DefaultConnectionString": "server=123.1.1.3;database=ab_db;uid=sa;pwd=sa;"
}
}
在Visual Studio中,项目属性下,可以查询环境变量
对应UI的配置文件在Properties下的launchSettings.json
{
"iisSettings": {
"windowsAuthentication": false,
"anonymousAuthentication": true,
"iisExpress": {
"applicationUrl": "http://localhost:55263",
"sslPort": 44313
}
},
"$schema": "http://json.schemastore.org/launchsettings.json",
"profiles": {
"AspNetCoreEnvironment": {
"commandName": "Project",
"launchBrowser": true,
"launchUrl": "swagger",
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
},
"dotnetRunMessages": "true",
"applicationUrl": "https://localhost:9001;http://localhost:9000"
}
}
}
对于Staging环境,如果使用DevOpt,可以在对应工具中来配置Staging或Production环境变量
Jenkins
配置全局环境变量,来配置对应asp.net core ASPNETCORE_ENVIRONMENT的运行时环境
dockerfile
ENV ASPNETCORE_ENVIRONMENT="Staging"
