Dalam penerapan Google Distributed Cloud, VM bidang kontrol untuk
cluster admin memiliki dua disk terpasang:
Boot disk memiliki sistem operasi untuk VM.
Disk data memiliki kredensial dan database etcd, yang menyimpan status
cluster admin. Artinya, disk data menyimpan semua objek Kubernetes untuk cluster admin.
Halaman ini menunjukkan cara memulihkan saat VM bidang kontrol hilang atau boot disk terganggu. Contoh:
Disk booting menjadi hanya baca karena log jurnal spam.
Sistem file overlay Docker rusak.
Halaman ini tidak mencakup pemulihan disk data. Untuk mengetahui petunjuk tentang cara memulihkan disk data, lihat Memulihkan cluster admin.
Memperbaiki VM bidang kontrol
Langkah-langkah yang Anda lakukan untuk memperbaiki VM panel kontrol cluster admin sedikit berbeda, bergantung pada apakah Anda memiliki cluster admin dengan ketersediaan tinggi (HA) atau cluster admin non-HA.
HA
Cluster admin HA memiliki tiga VM bidang kontrol. Anda harus memiliki setidaknya dua VM
untuk mengaktifkan bidang kontrol cluster. Jika tiga VM gagal, perbaiki VM yang gagal satu per satu. Setelah VM kedua diperbaiki dan berjalan,
bidang kontrol cluster akan aktif kembali.
ADMIN_CLUSTER_CONFIG dengan jalur file konfigurasi
cluster admin Anda.
ADMIN_CLUSTER_KUBECONFIG dengan jalur file kubeconfig
cluster admin Anda.
Output perintah ini akan mirip dengan berikut ini:
Please select the control plane VM template to be used for re-creating the admin cluster's control plane VM.

Masukkan nomor untuk VM yang ingin Anda perbaiki. Jika Anda tidak melihat VM dalam output, hubungi Google Cloud Dukungan.
Jika Anda memiliki tiga VM yang perlu diperbaiki, gkectl repair
admin-master akan menampilkan pesan error yang mirip dengan
berikut setelah memperbaiki VM pertama:
If you are repairing admin control plane VM for HA admin cluster,
it's possible that the API server is still down after repairing one
of the VMs. Try continue fixing other control plane VMs listed to
recover the quorum of control plane.
Dalam hal ini, jalankan kembali perintah untuk memperbaiki VM kedua.
ADMIN_CLUSTER_CONFIG dengan jalur file konfigurasi
cluster admin Anda.
ADMIN_CLUSTER_KUBECONFIG dengan jalur file kubeconfig
cluster admin Anda.
VM control plane cluster admin dikloning ke dalam template VM, yang memiliki semua informasi yang diperlukan untuk membuat ulang VM. Perintah gkectl repair admin-master
menggunakan template VM untuk membuat VM baru. Kemudian, instance akan melampirkan boot disk baru dan disk data yang ada.
Jika node cluster Anda mendapatkan alamat dari server DHCP, VM baru mungkin memiliki alamat IP yang berbeda dari VM asli.
