Question

我已经查看了kong-ingress-controller deployment和getting started文档，并做了提及的所有事情。

更新用户权限
部署Kong Ingress Controller
设置环境变量
使用路线创建的入口

一切正常，我可以根据路由访问我的应用程序。但是，当我添加速率限制插件或任何其他插件时，它没有任何效果。

ingress.yaml：


        package ndroid.bignerdranch.com;

        import android.os.Bundle;

    import android.view.LayoutInflater;
    import android.view.View;
    import android.view.ViewGroup;
    import android.widget.TextView;
    import android.widget.Toast;

    import java.util.List;

    import androidx.fragment.app.Fragment;
    import androidx.recyclerview.widget.LinearLayoutManager;
    import androidx.recyclerview.widget.RecyclerView;
    import ndroid.bignerdranch.com.R;

    public class CrimeListFragment extends Fragment {
        private RecyclerView mCrimeRecyclerView;
        private CrimeAdapter mAdapter;

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                                 Bundle savedInstanceState) {
            View view = inflater.inflate(R.layout.fragment_crime_list, container, false);

            mCrimeRecyclerView = (RecyclerView) view
                    .findViewById(R.id.crime_recycler_view);
            mCrimeRecyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));

            updateUI();

            return view;
        }

        private void updateUI() {
            CrimeLab crimeLab = CrimeLab.get(getActivity());
            List crimes = crimeLab.getCrimes();

            mAdapter = new CrimeAdapter(crimes);
            mCrimeRecyclerView.setAdapter(mAdapter);
        }

        private class CrimeHolder extends RecyclerView.ViewHolder
                implements View.OnClickListener {

            private Crime mCrime;

            private TextView mTitleTextView;
            private TextView mDateTextView;

            public CrimeHolder(LayoutInflater inflater, ViewGroup parent) {
                super(inflater.inflate(R.layout.list_item_crime, parent, false));
                itemView.setOnClickListener(this);

                mTitleTextView = (TextView) itemView.findViewById(R.id.crime_title);
                mDateTextView = (TextView) itemView.findViewById(R.id.crime_date);
            }

            public void bind(Crime crime) {
                mCrime = crime;
                mTitleTextView.setText(mCrime.getTitle());
                mDateTextView.setText(mCrime.getDate().toString());
            }

            @Override
            public void onClick(View view) {
                Toast.makeText(getActivity(),
                        mCrime.getTitle() + " clicked!", Toast.LENGTH_SHORT)
                        .show();
            }
        }

        private class CrimeAdapter extends RecyclerView.Adapter {

            private List mCrimes;

            public CrimeAdapter(List crimes) {
                mCrimes = crimes;
            }

            @Override
            public CrimeHolder onCreateViewHolder(ViewGroup parent, int viewType) {
                LayoutInflater layoutInflater = LayoutInflater.from(getActivity());
                return new CrimeHolder(layoutInflater, parent);
            }

            @Override
            public void onBindViewHolder(CrimeHolder holder, int position) {
                Crime crime = mCrimes.get(position);
                holder.bind(crime);
            }

            @Override
            public int getItemCount() {
                return mCrimes.size();
            }
        }
    }

rate-limit.yaml：

apiVersion: configuration.konghq.com/v1
kind: KongPlugin
metadata:
 name: http-ratelimit
 labels:
   global: 'true'
config:
 minute: 5
plugin: rate-limiting

但是限速插件对我的入口没有影响。

注意：kong-ingress-controller在kong名称空间中，而其他资源在默认名称空间中。我尝试将所有内容移到kong命名空间，然后插件可以工作，但服务无法正常工作，因为它在默认命名空间中。

谢谢。

Answer 1

从Kong docs看，速率限制YAML看起来正确。如果资源配置正确，则Kong不会将请求与入口资源匹配，因为用户没有发送正确的请求。

Answer 2

KongPlugin，KongIngress应该与Service位于同一命名空间中。 YAML提供的外观正确。 Ingress yamls注释和配置中肯定有问题。您的服务是否使用Ingress对象进行了注释？

Answer 3

我认为您需要将此注释添加到KongPlugin：

annotations:
  kubernetes.io/ingress.class: kong

所以尝试

apiVersion: configuration.konghq.com/v1
kind: KongPlugin
metadata:
 name: http-ratelimit
 annotations:
   kubernetes.io/ingress.class: kong
[...]

Kong Ingress Controller对Kong插件没有影响
