Kubeadm: kubelet tidak akan restart setelah reboot - Tidak dapat mendaftarkan node dengan server API: koneksi ditolak

halo @ PierrickI3

apakah Anda memiliki konektivitas ke:

https://192.168.1.19:6443

Saya tidak, tapi itu alamat IP lokal saya:

6443 adalah port aman dari server API.
apakah server API berjalan?

apa hasil dari kubectl get pods --all-namespaces

saya belum melihat kegagalan tepat setelah Watching apiserver ...

apakah Anda memiliki firewall yang memblokir 6443?
juga, dapatkah Anda membagikan manifes server API Anda? sembunyikan data sensitif apa pun, jika diperlukan.

Berikut adalah keluaran dari kubectl:

[pierrick<strong i="6">@kubernetes</strong> ~]$ kubectl get pods --all-namespaces
The connection to the server 192.168.1.19:6443 was refused - did you specify the right host or port?

Saya tidak memiliki firewall yang memblokir port ini dan saya langsung melakukan ssh di mesin.

Berikut manifesnya (tidak ada data sensitif untuk disembunyikan karena tidak terekspos):

yang ini harus ditinggalkan dan dinonaktifkan secara default di 1.11.1, apakah Anda mengadaptasi konfigurasi kubeadm lama?
(edit: oh, tunggu kami tidak memilih ini: https://github.com/kubernetes/kubernetes/pull/65827)

apa isi konfigurasi kubeadm Anda (sekali lagi, harap sembunyikan data sensitif jika diperlukan)?

# REBOOTING ISSUE #
###################
# At the time of writing this, rebooting causes kubernetes to no longer work. This will fix it (http://stytex.de/blog/2018/01/16/how-to-recover-self-hosted-kubeadm-kubernetes-cluster-after-reboot/)
git clone https://github.com/xetys/k8s-self-hosted-recovery
cd k8s-self-hosted-recovery
chmod +x install.sh
./install.sh
cd ..

kubeadm init --pod-network-cidr=10.244.0.0/16

dalam hal ini Anda tidak meneruskan --config jadi konfigurasi Anda cukup banyak:
kubeadm config print-default + perubahan CIDR.

apa yang terjadi jika Anda menggunakan CNI yang berbeda?
(Saya tahu itu berfungsi sebelum reboot tetapi hanya menguji ...).

pertama ini tanpa CIDR:

# deploy kubernetes
kubeadm init

kemudian:

# deploy pod network (weave)
kubectl apply -f "https://cloud.weave.works/k8s/net?k8s-version=$(kubectl version | base64 | tr -d '\n')"
kubectl taint nodes --all node-role.kubernetes.io/master- # allow pods to be scheduled on master

edit: mainkan dengan menghapus garis noda:
kubectl taint nodes --all node-role.kubernetes.io/master- ...

haruskah saya menjalankan kubeadm reset sebelum mencoba lagi? atau cukup jalankan kubeadm init dan kemudian muat CIDR?

haruskah saya menjalankan reset kubeadm sebelum mencoba lagi?

ya, kecuali jika Anda punya alasan untuk tidak mau?

Saya menjalankan kubeadm reset dan kemudian terjadi kesalahan setelah [init] this might take a minute or longer if the control plane images have to be pulled :

                Unfortunately, an error has occurred:
                        timed out waiting for the condition

                This error is likely caused by:
                        - The kubelet is not running
                        - The kubelet is unhealthy due to a misconfiguration of the node in some way (required cgroups disabled)
                        - No internet connection is available so the kubelet cannot pull or find the following control plane images:
                                - k8s.gcr.io/kube-apiserver-amd64:v1.11.1
                                - k8s.gcr.io/kube-controller-manager-amd64:v1.11.1

                                - k8s.gcr.io/etcd-amd64:3.2.18
                                - You can check or miligate this in beforehand with "kubeadm config images pull" to make sure the images
                                  are downloaded locally and cached.

                If you are on a systemd-powered system, you can try to troubleshoot the error with the following commands:
                        - 'systemctl status kubelet'
                        - 'journalctl -xeu kubelet'

                Additionally, a control plane component may have crashed or exited when started by the container runtime.
                To troubleshoot, list all containers using your preferred container runtimes CLI, e.g. docker.
                Here is one example how you may list all Kubernetes containers running in docker:
                        - 'docker ps -a | grep kube | grep -v pause'
                        Once you have found the failing container, you can inspect its logs with:
                        - 'docker logs CONTAINERID'

lalu coba lagi init .
jika gagal lagi apa yang dikatakan journalctl tentang kubelet?

                                - k8s.gcr.io/kube-apiserver-amd64:v1.11.1
                                - k8s.gcr.io/kube-controller-manager-amd64:v1.11.1
                                - k8s.gcr.io/kube-scheduler-amd64:v1.11.1
                                - k8s.gcr.io/etcd-amd64:3.2.18
                                - You can check or miligate this in beforehand with "kubeadm config images pull" to make sure the images
                                  are downloaded locally and cached.

                If you are on a systemd-powered system, you can try to troubleshoot the error with the following commands:
                        - 'systemctl status kubelet'
                        - 'journalctl -xeu kubelet'

                Additionally, a control plane component may have crashed or exited when started by the container runtime.
                To troubleshoot, list all containers using your preferred container runtimes CLI, e.g. docker.
                Here is one example how you may list all Kubernetes containers running in docker:
                        - 'docker ps -a | grep kube | grep -v pause'
                        Once you have found the failing container, you can inspect its logs with:
                        - 'docker logs CONTAINERID'
couldn't initialize a Kubernetes cluster

Saya belum dapat menambahkan pod jaringan apa pun.

Saya belum dapat menambahkan pod jaringan apa pun.

ya, ini gagal sebelumnya.

pull images bekerja menyiratkan bahwa Anda memiliki konektivitas ke keranjang gcr.io .

tolong, restart kubelet secara manual dan lihat apa yang ditampilkan log:

systemctl restart kubelet

systemctl status kubelet # <---- ?
journalctl -xeu kubelet   # <---- ?

Saya kehabisan ide.

• Menjalankan systemctl restart kubelet
• systemctl status kubelet :

apa yang terjadi jika Anda menghentikan semua yang berhubungan dengan kubernetes di node ini dan mencoba menjalankan server kecil yang mendengarkan 192.168.1.19:6443 ?

kubeadm reset
systemctl stop kubelet

netstat -tulpn
untuk memastikan tidak ada yang mendengarkan di sana.

tulis ini ke file test.go

Apakah itu bekerja?

Saya tahu ini konyol, tapi saya kehabisan ide.

Output dari netstat -tulpn :

keluaran curl setelah menjalankan test.go :

[pierrick<strong i="12">@kubernetes</strong> ~]$ curl 192.168.1.19:6443
Hello [pierrick<strong i="13">@kubernetes</strong> ~]$

baik itu berhasil!
saya minta maaf tapi saya tidak bisa membantu lebih banyak hari ini.

mungkin orang lain bisa melihat log dan mencari tahu apa yang terjadi?

Adakah yang secara khusus Anda pikirkan? Bisakah Anda menandai mereka dalam masalah ini?

@ kubernetes / sig-cluster-lifycle-bugs

@ PierrickI3 Dapatkah Anda memeriksa apakah server aplikasi mendengarkan pada port 6443? Jika ya, dapatkah Anda memeriksa pengaturan proxy Anda (jika ada)?

netstat -tulpn |grep 6443
set |grep -i proxy

@ bart0sh Terima kasih, tetapi saya harus memulai akhir pekan ini sehingga saya tidak dapat lagi memecahkan masalah ini. Saya akan menutup masalah ini.

FYI, output dari netstat -tulpn ditunjukkan di atas (https://github.com/kubernetes/kubeadm/issues/1026#issuecomment-408457991). Saya tidak memiliki proxy (koneksi langsung ke internet).

Mengapa ini ditutup? Saya menghadapi masalah serupa di VM VirtualBox saya dengan Centos 7 ..
Jadi satu-satunya solusi adalah membuat kotak baru sekaligus ???

@ PierrickI3 Saya mengalami masalah yang sama persis dan kebanyakan log serupa. Apakah Anda mencapai solusi atau solusi ??

@ sayangnya tidak. Saya menyerah dan pindah kembali ke minikube untuk tujuan dev. Tetapi saya ingin kembali ke kubeadm jika solusi ditemukan.

@ PierrickI3 ok .. ketika saya mencapai sesuatu maka saya akan memberi tahu Anda

masalah yang sama menjalankan Ubuntu 16 di VMWare.

masalah yang sama berjalan di RHEL 7.5

masalah yang sama berjalan di cluster Centos7

sama dengan cluster Kubic

coba ini di setiap node @ PierrickI3

systemctl menghentikan kubelet
systemctl menghentikan buruh pelabuhan
iptables --flush
iptables -tnat --flush
systemctl mulai kubelet
systemctl mulai buruh pelabuhan

Mungkin Anda lupa menjalankan ini setelah menginstal @ PierrickI3 :

sudo cp /etc/kubernetes/admin.conf $ BERANDA /
sudo chown $ (id -u): $ (id -g) $ HOME / admin.conf
ekspor KUBECONFIG = $ HOME / admin.conf

Kami mengalami masalah yang sama persis pada RHEL 7. Ini baru saja berhenti bekerja begitu saja. Ini penting bagi kami.

aku harus lari
sudo cp /etc/kubernetes/admin.conf $ BERANDA /
sudo chown $ (id -u): $ (id -g) $ HOME / admin.conf
ekspor KUBECONFIG = $ HOME / admin.conf

dll., dll., tetapi node master menolak koneksi bahkan ke semua node di cluster kita.

saya tidak pernah dapat mereproduksi masalah ini, cluster baru saja kembali dengan baik setelah 2-3 menit setelah reboot.
harus sesuatu yang berhubungan dengan pengaturan individu.

Sepertinya server API saya tidak lagi berjalan. Saya sudah mencoba me-restart kubelet beberapa kali, semuanya tidak berhasil. Lucunya, ini telah berhasil dan saya belum menyentuhnya sampai kemarin ketika saya akan menambahkan lebih banyak gambar buruh pelabuhan untuk cluster kami.

Saya tahu apa yang sedang terjadi. Direktori yang dipasang /var telah penuh. Sekarang bekerja seperti yang diharapkan.

Saya pikir karena aturan untuk port 6443 ditambahkan ke iptables dan karena saya mendapatkan koneksi terus-menerus ditolak, bahkan dari localhost dan sejak melakukan docker ps tidak menghasilkan kontainer yang berjalan, bahwa layanan API (dan layanan lainnya) ) tidak berjalan, artinya sesuatu yang ganjil sedang terjadi, dan tentu saja ... hal yang aneh tidak ada dalam log kubectl menunjukkan mengapa layanan API gagal dimulai.

Saya tahu apa yang sedang terjadi. Direktori yang dipasang /var telah penuh.

OMG TERIMA KASIH !!!

Ini memperbaiki masalah saya, meskipun saya hanya melakukan ini di node master dan baru saja melakukan reset kubeadm di node lain

Terima kasih @ manoj-bandara tetapi saya menyerah untuk saat ini dan akan kembali ke ini nanti tahun ini. Lihat https://github.com/kubernetes/kubeadm/issues/1026#issuecomment -420948092

masalah yang sama di sini - mencoba banyak hal. sepertinya inilah masalahnya:
failed: open /run/systemd/resolve/resolv.conf: no such file or directory

saya menghubungkan /etc/resolv.conf ke lokasi itu dan memulai ulang kubele (hanya di master) lalu master dan semua node mulai muncul lagi.

Dalam kasus saya itu adalah masalah swap, perbaiki dengan mematikan swap

sudo swapoff -a
sudo systemctl restart kubelet.service

coba ini di setiap node @ PierrickI3

systemctl menghentikan kubelet
systemctl menghentikan buruh pelabuhan
iptables --flush
iptables -tnat --flush
systemctl mulai kubelet
systemctl mulai buruh pelabuhan

OMG, perintah luar biasa !! Terima kasih banyak !!

@JTRNEO , saya harus mengingat yang ini juga :)

Saya menghadapi masalah yang sama beberapa instalasi. Saya belum menemukan jawabannya. Saya mencoba driver Flanel, Calico dan Wave dan hasilnya sama. Jadi mungkin masalahnya tidak terkait dengan plugin jaringan.
Saya tidak yakin ini terkait dengan masalah tetapi meskipun saya menjalankan "sudo swapoff -a", setelah restart server merekomendasikan saya untuk mematikan swap lagi.

Masalah yang sama di sini. Log kube-apiserver saya diisi dengan:

Tabel ip pembilasan tidak berfungsi untuk saya dan swap saya sudah dimatikan.

Apakah Anda memasang flanel ke node pekerja?

Tidak, saya menggunakan kube-router untuk jaringan. Pod untuk itu berada dalam status crash backoff, dan berisi kesalahan tentang tidak dapat berbicara dengan server api.

Cluster ini berjalan dengan baik selama berbulan-bulan, tetapi kemudian listrik padam sehingga me-reboot mesin saya dan cluster yang rusak.

@bayu_joo
mungkinkah sertifikat klien kubelet Anda telah kedaluwarsa?

lihat peringatan kedua di sini:
https://kubernetes.io/docs/tasks/administer-cluster/kubeadm/kubeadm-certs/#check -certificate-expiration

Pada node yang dibuat dengan kubeadm init, sebelum kubeadm versi 1.17 ...

masalah yang sama menjalankan Ubuntu 16 di VMWare.

Saya menjalankan cluster di vmware juga, apa yang menyelesaikan masalah Anda? Terima kasih

Memiliki masalah yang sama hari ini setelah mengedit pengaturan service-cidr di cluster kube baru saya. Masalah bagi saya adalah kontainer buruh pelabuhan kube-apiserver sedang mengepak. Setelah melihat log menggunakan log buruh pelabuhan, Saya melihat:
Error: error determining service IP ranges for primary service cidr: The service cluster IP range must be at least 8 IP addresses.
Saya memiliki meskipun saya dapat menyediakan cidr / 30 yang lebih kecil untuk layanan, tetapi perlu membukanya ke / 29.

tidak yakin apakah terkait tetapi perhatikan bahwa 1.17.0 memiliki bug terkait CIDR, jadi semoga Anda menjalankan patch yang lebih baru .17.

Anda mungkin perlu mengubah aturan iptables.
jalankan CMD: iptables -L --line-numbers untuk menemukan penolakan-dengan icmp-host-dilarang
kemudian, iptables -D INPUT 153, hapus # 153 berarti nomor baris
akhirnya, mulai ulang kubelet

Saya memiliki masalah serupa menggunakan cluster kubeadm. Saya baru saja menggunakan 2x kali docker restart $ (docker ps -qa)

Memiliki masalah yang sama dengan @ PierrickI3 . Setelah reboot bidang kontrol node turun. kubelet layanan sedang berjalan mencoba menyambung ke apiserver yang tidak berjalan. etcd sedang berjalan. Tidak ada antarmuka jaringan CNI, hanya loopback, ethernet, dan buruh pelabuhan.

Tidak ada kesalahan khusus yang terlihat di mana pun, itu tidak dimulai, meskipun berfungsi dengan baik untuk waktu yang lama sebelum reboot. Mencoba semua yang disebutkan di utas ini serta di banyak lainnya.

Saya benar-benar bingung tentang apa yang memulai apa di sini untuk menyelidiki masalah lebih lanjut. Apakah kubelet service memulai jaringan CNI dan kemudian memulai bidang kontrol (mis. Api, penjadwal, dll.) Pod? Saya telah memeriksa docker ps -a dan semua container control plane belum dicoba untuk dijalankan, juga, tidak ada kebijakan restart pada container tersebut. Jadi mengapa kubelet mencoba untuk berbicara dengan server api ketika itu belum memulainya?

Memiliki masalah serupa, ini belum terselesaikan untuk saya tetapi masalah terjadi karena buruh pelabuhan ditingkatkan ke versi yang tidak kompatibel. Cukup periksa apakah layanan buruh pelabuhan Anda berjalan atau tidak.

systemctl restart docker

Ini bekerja dengan baik

Hai,
Silakan coba untuk melihat apakah Anda mengaktifkan swap pada node master dan pekerja. Harap nonaktifkan dan mulai ulang layanan.
