在Debian上優化Kubernetes(K8s)性能可以從多個方面入手,包括硬件配置、內核參數調整、Kubernetes組件調優、網絡優化等。以下是一些具體的優化建議:
echo "fs.file-max 100000" | sudo tee -a /etc/sysctl.conf
sudo sysctl -p
echo "net.core.somaxconn 65535" | sudo tee -a /etc/sysctl.conf
echo "net.ipv4.tcp_max_syn_backlog 65535" | sudo tee -a /etc/sysctl.conf
echo "net.ipv4.ip_local_port_range 1024 65535" | sudo tee -a /etc/sysctl.conf
echo "net.ipv4.tcp_tw_reuse 1" | sudo tee -a /etc/sysctl.conf
echo "net.ipv4.tcp_fin_timeout 30" | sudo tee -a /etc/sysctl.conf
echo "net.ipv4.tcp_max_tw_buckets 180000" | sudo tee -a /etc/sysctl.conf
echo "vm.swappiness 10" | sudo tee -a /etc/sysctl.conf
echo "vm.vfs_cache_pressure 50" | sudo tee -a /etc/sysctl.conf
sudo sysctl -p
kubelet --concurrent-endpoints 1000 --max-pods 110
sysctl -w net.ipv4.ip_vs_mode=1
--max-requests-inflight 1000 --min-request-timeout 30s
通過以上這些優化措施,可以顯著提升Debian上Kubernetes集群的性能和穩定性。不過,具體的優化策略需要根據實際的應用場景和硬件環境進行調整。
