昨日の Istio の Envoy Proxy のメモリ使用量の調査の続き。
前の投稿ではあまりメモリ消費量を増やせなかったので、問題となっているアプリを想定した構成にしたところ、メモリ使用量を大きくすることができた。 問題となっているアプリケーションは 1 Deployment が全て 1 Replica であり、各 Deployment には 1-2 の Service がある。1 Namespace にはこの Deployment が 50 個程度ある。
また Sidecar リソースを使って Namespace Isolation を行った場合の効果も合わせて測定した。
準備
m6i.large (2 core) を 100 ノードの構成にする。
$ k get nodes | head NAME STATUS ROLES AGE VERSION ip-10-0-101-103.ap-northeast-1.compute.internal Ready <none> 77m v1.29.6-eks-1552ad0 ip-10-0-101-58.ap-northeast-1.compute.internal Ready <none> 77m v1.29.6-eks-1552ad0 ip-10-0-102-166.ap-northeast-1.compute.internal Ready <none> 77m v1.29.6-eks-1552ad0 ip-10-0-102-32.ap-northeast-1.compute.internal Ready <none> 77m v1.29.6-eks-1552ad0 ip-10-0-104-145.ap-northeast-1.compute.internal Ready <none> 77m v1.29.6-eks-1552ad0 ip-10-0-104-163.ap-northeast-1.compute.internal Ready <none> 77m v1.29.6-eks-1552ad0 ip-10-0-104-37.ap-northeast-1.compute.internal Ready <none> 77m v1.29.6-eks-1552ad0 ip-10-0-104-43.ap-northeast-1.compute.internal Ready <none> 77m v1.29.6-eks-1552ad0 ip-10-0-106-38.ap-northeast-1.compute.internal Ready <none> 20h v1.29.6-eks-1552ad0 $ k get nodes | wc -l 101
計測用の Pod を配置する Namespace を 2 つ用意する。片方には Sidecar リソースを作成し、自分自身の Namespace と istio-system Namespace との通信だけを許可する。
k create ns measure1 k label namespace measure1 istio-injection=enabled k -n measure1 create deployment test1 --image=public.ecr.aws/docker/library/nginx --replicas=1 k create ns measure2 k label namespace measure2 istio-injection=enabled k -n measure2 create deployment test1 --image=public.ecr.aws/docker/library/nginx --replicas=1 cat <<EOF | kubectl apply -f - apiVersion: networking.istio.io/v1 kind: Sidecar metadata: name: default namespace: measure2 spec: egress: - hosts: - "./*" - "istio-system/*" EOF

テスト実施
テストは以下のようなスクリプトを実行して行う。アプリを 10 インスタンス作成し、その際にメモリ使用量の変化を測定する。
