a2d - appsettings.json to Docker .env format

This small tool is useful to quickly translate dotnet appsettings.json files to Docker environment format

Sample

Input file sample

{
  "ConnectionStrings": {
    "MyConnection": "Data Source=localhost;Initial Catalog=Demo;Trusted_Connection=True;"
  },
  "SqlServer": {
    "MaxRetryCount": 30,
    "MaxRetryDelay": "00:05:00",
    "ErrorNumbersToAdd": [] 
  }
}

Output sample

ConnectionStrings__MyConnection=Data Source=localhost;Initial Catalog=Demo;Trusted_Connection=True;
SqlServer__MaxRetryCount=30
SqlServer__MaxRetryDelay=00:05:00

Usage

a2d.exe --appsettings <PATH_TO_YOUR_APPSETTINGS_FILE>

You can obviously redirect the output to a file like this

a2d.exe --appsettings <PATH_TO_YOUR_APPSETTINGS_FILE> > .env
