我正在尝试使用Apache Ignite进行设置。
我有一个dotnet核心客户端应用程序，它试图获取缓存（ignite.GetCache<int, CacheThing>("test-cache")或创建缓存（'ignite.CreateCache'）。
在两种情况下，结果都是相同的错误（请参见下文）。
我正在使用https://hub.docker.com/r/apacheignite/ignite/中的docker容器，并且正在使用apache/ignite:2.6.0标签。
客户端正在尝试使用用于模式定义的自定义dotnet核心程序集创建缓存。
class Program
{
public static bool ClientDisconnected = false;
static void Main(string[] args)

Console.WriteLine("Cache factory: " + x);
var cfg = new IgniteConfiguration
{
SpringConfigUrl = "ignite.config",
JvmOptions = new[]
{
"-Xdebug","-DIGNITE_QUIET=false"

Console.WriteLine("Ignite -> Start");

dotnet客户端甚至有可能在Apache Ignite Java服务器中创建缓存吗？
答案 0 :(得分：1)
.NET缓存存储can not be deployed on Java-only node。
Docker容器包含仅Java的Ignite，您可以在C＃代码中创建自定义缓存存储。
因此，除非Ignite团队发布运行Ignite.NET的Docker映像，否则您必须创建自定义Docker映像或以其他方式启动Ignite.NET服务器节点。
