Container Service for Kubernetes:Buat dan kelola kelompok node Windows di kluster ACK

Resource reservation

Sejak Mei 2021, node Windows di kluster ACK versi 1.16 atau lebih baru secara otomatis menyediakan cadangan sumber daya berikut saat startup:

• 1,5 vCPU

• RAM 2,5 GB

• Disk space 3 GB

Hal ini memastikan stabilitas OS, kubelet, dan runtime. Kontainer Windows tidak memicu OOM kills ketika melebihi batas memori, tetapi memory leak pada kontainer tetap dapat menyebabkan node crash. Lihat Node resource reservation policy dan Memory requirements for Windows containers.

Console

1. Masuk ke ACK console. Di panel navigasi kiri, klik Clusters.

2. Pada halaman Clusters, klik nama kluster target, lalu pilih Nodes > Node Pools di panel navigasi kiri.

3. Pada halaman Node Pools, klik Create Node Pool dan konfigurasikan parameter berikut. Lihat Create and manage node pools.

   Parameter	Setting
   Configure Managed Node Pool	Pilih Disable
   Container Runtime	Pilih containerd
   Instance Type	Pilih tipe instans dengan minimal 4 vCPU dan memori 8 GB — misalnya, ecs.g6.xlarge. Jangan pilih tipe instans Elastic GPU Service. Lihat Instance families.
   Expected Number of Nodes	Jumlah node target. Kelompok akan secara otomatis diskalakan hingga mencapai nilai ini.
   Operating System	Pilih citra Windows Server
   ECS Tags	(Opsional) Tag yang diterapkan pada instance ECS yang mendasari
   Node Labels	(Opsional) Label Kubernetes yang diterapkan pada node

4. Selesaikan langkah-langkah tersisa dan kirim.

Kelompok node siap digunakan ketika Status-nya berubah menjadi Active pada halaman Node Pools.
