How to do gracefully shutdown on dotnet with docker?


c# .net docker .net-core

In .NET Core 2.0, you can use the AppDomain.CurrentDomain.ProcessExit event, which works fine on Linux in Docker. AssemblyLoadContext.Default.Unloading probably works as well, even before .NET Core 2.0.

c# .net docker .net-core

System.Console has an event called CancelKeyPress. I believe this is fired when a sigint event is passed into dotnet.

System.Console.CancelKeyPress += (s,e) => { /* do something here */};

c# .net docker .net-core

Using 2.0.0-preview2-006497 I did some testing, and now the AssemblyLoadContext.Default.Unloading is fired when Docker sends a SIGTERM/SIGINT to the container.

Example code looks like:

System.Runtime.Loader.AssemblyLoadContext.Default.Unloading += ctx =>{    // code here...};
