通过docker-compose文件修改环境json数组变量

Question

I'm trying to modify environment variables of my application via docker-compose.yml file.

My appsettings.Development.json looks like below:

{
  "ConnectionStrings": {
    "DefaultConnection": "Server=127.0.0.1,1433;Database=app;User Id=sa;Password=P@ssw0rd"
  },
  "EventBusSettings": {
    "HostAddress": "amqp://guest:guest@localhost:5672"
  },
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft": "Warning",
      "Microsoft.Hosting.Lifetime": "Information"
    }
  },
  "Roles": [
    "Member",
    "Admin"
  ]
}

Using docker-compose.yml I modify ConnectionStrings:DefaultConnection and EventBusSettings:HostAddress like in example below:

# ...
app:
    image: app
    container_name: app
    build:
      context: .
      dockerfile: Services/App/Dockerfile
    ports:
      - 5000:5000
    depends_on:
      - db
      - rabbitmq
      - portainer
    environment:
      - ConnectionStrings:DefaultConnection=Server=db,1433;Database=app;User Id=sa;Password=P@ssw0rd
      - EventBusSettings:HostAddress=amqp://guest:guest@rabbitmq:5672
# ...

How can I modify first element of Roles in appsettings.Development.json via docker-compose.yml?

您可以通过将Roles__0设置为您想要的值来实现。
