Kubeadm: a rede em tempo de execução não está pronta: NetworkReady = falso motivo: NetworkPluginNotReady mensagem: docker: o plugin de rede não está pronto: cni config não inicializado

Parece que os nós não estão recebendo flanela porque estão na arquitetura amd64

Não sou especialista em flanela, mas acho que você deve verificar a documentação do produto para saber como fazê-lo funcionar em um ambiente com plataformas mistas

Esse é um bom ponto, mas que tal mensagem de erro - parece realmente não relacionado.

runtime network not ready: NetworkReady=false reason:NetworkPluginNotReady message:docker: network plugin is not ready: cni config uninitialized

Parece que alguns arquivos de configuração CNI estão faltando em /etc/cni/net.d mas por quê?
Agora estou tentando um docker diferente 18.03ce conforme sugerido no canal slack (17.03 foi sugerido, mas não há 17.03 para Ubuntu 18.04).

As etiquetas com o nome do arco não correspondem de fato. Mas o próximo rótulo beta.kubernetes.io/os=linux é o mesmo em todos os 3 servidores.

O mesmo acontece com o Docker 18.03ce. Não vejo nenhuma diferença, isso não parece ser um problema do docker. Isso parece um problema de configuração CNI.

Oi,

Mestre: Servidor de 96 núcleos de metal puro, ARM64, 128G RAM, swap desligado.
Nós (2): servidor bare metal 48 núcleos, AMD64, 256 G RAM, troca ajustada x 2.

essas são algumas especificações _agradáveis_.

a maneira como eu testo as coisas é a seguinte - se algo não funcionar com o weavenet, eu tento flanela e vice-versa.

então, por favor, tente weave e se sua configuração CNI funcionar com ele, então este é o plugin CNI relacionado.

embora a equipe do kubeadm ofereça suporte a plug-ins e complementos, geralmente delegamos problemas a seus respectivos mantenedores, porque não temos largura de banda para lidar com tudo.

Claro, tentei tecer algumas iterações atrás. Terminou em um loop de reinicialização do contêiner.
Agora tentarei o docker 17.03 para excluir o problema do docker (17.03 deve ser muito bem suportado).

Portanto, este não é um problema do docker. Em 17.03 o mesmo:

now will try weave net as suggested on the issue

Vou tentar tecer agora e postar os resultados aqui.

Então, tentei weave net e não está funcionando:
No mestre: kubectl get nodes :

Então, resumindo. É impossível instalar o cluster Kubernetes com apenas um único nó mestre e de trabalho no Ubuntu 18.04.
Acho que deve haver uma instrução de instalação sobre como configurar o k8s passo a passo usando o kubeadm no mais novo LTS Ubuntu.

acho que 18,04 quebrou tanto em termos do Docker que empacota quanto por systemd-resolved .
então sim, é muito difícil escrever guias para cada tipo de distro que existe e não podemos realmente mantê-los com eficiência.

Além disso, embora o kubeadm seja o front-end aqui, o problema realmente pode não estar relacionado ao próprio kubeadm.

algumas perguntas:

• você tem executado clusters amd64 + arm64 com êxito com versões recentes do kubernetes?
• Eu me pergunto se este é um problema de proxy. os nós estão atrás de um proxy?
• qual é o conteúdo de /var/lib/kubelet/kubeadm-flags.env quando você começa kubeadm join/init nos 3 nós?
• esses são os únicos conteúdos interessantes de journalctl -xeu kubelet ? isso ocorre apenas no nó mestre - e os outros? você pode despejá-los em um github gist ou em http://pastebin.com para que eu também dê uma olhada.

• você tem executado clusters amd64 + arm64 com êxito com versões recentes do kubernetes? Não, esta é minha primeira tentativa, mas também tentarei instalar o master no host amd64 e um único nó com outro host amd64 para excluir o problema relacionado ao arm64
• Eu me pergunto se este é um problema de proxy. os nós estão atrás de um proxy? nenhum proxy, todos os 3 servidores têm IPs estáticos
• quais são os conteúdos de /var/lib/kubelet/kubeadm-flags.env quando você inicia o junção / init do kubeadm nos 3 nós?
  mestre (devstats.team.io, arm64):

KUBELET_KUBEADM_ARGS=--cgroup-driver=cgroupfs --cni-bin-dir=/opt/cni/bin --cni-conf-dir=/etc/cni/net.d --network-plugin=cni --resolv-conf=/run/systemd/resolve/resolv.conf

nó (cncftest.io, amd64):

KUBELET_KUBEADM_ARGS=--cgroup-driver=cgroupfs --cni-bin-dir=/opt/cni/bin --cni-conf-dir=/etc/cni/net.d --network-plugin=cni --resolv-conf=/run/systemd/resolve/resolv.conf

nó (devstats.cncf.io, amd64):

KUBELET_KUBEADM_ARGS=--cgroup-driver=cgroupfs --cni-bin-dir=/opt/cni/bin --cni-conf-dir=/etc/cni/net.d --network-plugin=cni --resolv-conf=/run/systemd/resolve/resolv.conf

• são esses os únicos conteúdos interessantes do journalctl -xeu kubelet? isso ocorre apenas no nó mestre - e os outros? você pode despejá-los em um github gist ou em http://pastebin.com para que eu também dê uma olhada.

Pastebins: mestre , nó .

Portanto, instalei o master kubeadm init no host amd64 e tentei weave net e o resultado é exatamente o mesmo de quando tentei no host arm64:

• Recuar reiniciando contêiner com falha
• runtime network not ready: NetworkReady=false reason:NetworkPluginNotReady message:docker: network plugin is not ready: cni config uninitialized

Há um pequeno progresso.
Eu instalei o master no amd64 e um nó no amd64 também. Tudo funcionou bem.
Eu adicionei o nó arm64 e agora tenho:
mestre amd64: pronto
nó amd64: pronto
nó arm64: NotReady: runtime network not ready: NetworkReady=false reason:NetworkPluginNotReady message:docker: network plugin is not ready: cni config uninitialized

• Portanto, parece que flannel net plugin não pode se comunicar entre arquiteturas diferentes e arm64 não pode ser usado como um mestre.
• O plugin Weave net não está funcionando (mesmo sem adicionar nós). Master está sempre no estado NotReady, não importa se arch é amd64 ou arm64.
• Em todos esses casos, o motivo de 'NotReady' é sempre o mesmo: runtime network not ready: NetworkReady=false reason:NetworkPluginNotReady message:docker: network plugin is not ready: cni config uninitialized

Alguma sugestão do que devo fazer? Onde devo relatar isso? Eu já tenho um cluster de 2 nós (mestre e nó amd64), mas quero ajudar a resolver esse problema para que se possa usar qualquer mestre de arco com qualquer nó de arco apenas OOTB.

@lukaszgryglicki
kube-flannel.yml implanta o contêiner de flanela para apenas uma arquitetura. É por isso que em nós com arquiteturas diferentes o plugin cni não inicia e o nó nunca fica pronto

Eu nunca tentei sozinho, mas acho que você pode implantar dois manifestos de flanela hackeados com manchas diferentes (nomes ands) para evitar confundir as coisas, mas novamente minha sugestão é pedir para flanear as pessoas se já houver instruções sobre como fazer isso .

Mas eu ajustei o manifest no arm64 conforme sugerido no tutorial. Substituído amd64 por arm64 .
Então, talvez eu crie um problema para flannell e cole um link para este tópico.

E agora, por que wave net falha em ambos os archs com o mesmo bug relacionado ao cni? Talvez criar um problema para weave também e também criar um link para este tópico?

@lukaszgryglicki
Quando você aperta kube-flannel.yml para arm, ele para de funcionar em máquinas amd ... É por isso que estou supondo que a implantação de 2 manifestos bem ajustados, um para arm e um para amd, pode resolver seu problema.

E agora que penso, talvez você deva corrigir o mesmo problema com o daemon kube-proxy definido também, mas não posso testar isso agora, desculpe

Para o problema que você tem com o weave, não tenho informações suficientes. Um problema pode ser que o weave não funciona com --pod-network-cidr=10.244.0.0/16 , mas voltando ao problema inicial, não sei de fato se o weave funciona fora da caixa em plataformas mistas ou não.

Portanto, devo implantar dois manifestos diferentes para flanela em um mestre, certo? Não importa se o master é arm64 ou amd64, certo? O Mestre deve lidar com a geração de implantação correta do arco em si mesmo e nos nós?
Não tenho certeza do que você quer dizer aqui:

And now that I think of, might be you should fix the same issue with kube-proxy daemon set as well, but I can't test this now, sorry

Eu não usei --pod-network-cidr=10.244.0.0/16 para weave . Usei apenas kubeadm init .
Usei --pod-network-cidr=10.244.0.0/16 apenas para tentativas de flanela. Exatamente como dizem os médicos.

cc @luxas - Eu vi que você criou alguns documentos sobre implantações multi-arch k8s, talvez você possa dar algum feedback.

@lukasredynk

sim, então este é um problema de arco afinal, obrigado por confirmar.
vamos nos concentrar na flanela aqui, já que a questão da tecelagem parece tangente.

dê uma olhada em @luxas para o contexto, se ainda não viu:
https://github.com/luxas/kubeadm-workshop

O Mestre deve lidar com a geração de implantação correta do arco em si mesmo e nos nós?

_ deveria_, mas o manifesto que você está baixando não é um "gordo":
https://raw.githubusercontent.com/coreos/flannel/v0.10.0/Documentation/kube-flannel.yml

Tanto quanto eu entendo, os arquétipos são propagados e você precisa consertar isso com kubectl em cada nó (?).

parece que um manifesto "gordo" está no mestre e foi adicionado aqui:
https://github.com/coreos/flannel/commit/c5d10c8b16d7c43bfa6e8408673c6d95404bd807#diff -7891b552b026259e99d479b5e30d31ca

questão / pr:
https://github.com/coreos/flannel/issues/663
https://github.com/coreos/flannel/pull/989

minha suposição é que isso é o que há de mais moderno e você deve usar:

kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

então, desative o cluster e experimente e espere que funcione.
nossos documentos CNI precisariam de um aumento, mas isso precisa acontecer quando flannel-next for lançado.

Ok, vou tentar depois do final de semana e postar meus resultados aqui. Obrigado.

@lukaszgryglicki oi, você conseguiu fazer isso funcionar usando o novo manifesto de flanela?

Ainda não, vou tentar hoje.

OK finalmente funcionou:

root<strong i="6">@devstats</strong>:/root# kubectl get nodes

devstats.team.io   Ready     master    12m       v1.11.1

Fat mainifest da flanela master branch ajudou.
Obrigado, isso pode ser fechado.

Oi pessoal, estou na mesma situação.
Eu tenho nós de trabalho no estado Pronto, mas a flanela em arm64 continua travando com este erro:
1 main.go:232] Failed to create SubnetManager: error retrieving pod spec for 'kube-system/kube-flannel-ds-arm64-m5jfd': Get https://10.96.0.1:443/api/v1/namespaces/kube-system/pods/kube-flannel-ds-arm64-m5jfd: dial tcp 10.96.0.1:443: i/o timeout
@lukasredynk funcionou para você?

qualquer ideia?

O erro parece diferente, mas você usou o manifesto fat: https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml ?
Ele contém manifestos para vários arcos.

Sim, eu sou:

O problema agora é o recipiente de flanela que não fica de pé. :(

funciona em amd64 e arm64 - funciona para mim.
Infelizmente, não posso ajudar com arm (32 bits), não tenho uma máquina arm disponível.

Estou no braço64, mas obrigado, vou continuar a investigar ...

Ohh então desculpe, pensei que você estava de braço dado.
De qualquer forma, também sou muito novo nisso, então você precisa esperar a ajuda de outros caras.
Cole a saída de kubectl describe pods --all-namespace e a possível saída de outros comandos que postei neste tópico. Isso pode ajudar alguém a rastrear o problema real.

Obrigado @lukaszgryglicki ,
esta é a saída de descrever pods: https://pastebin.com/kBVPYsMd

@lukaszgryglicki
feliz que funcionou no final.
Vou documentar o uso do manifesto de gordura para flanela na documentação, já que não tenho ideia de quando o 0.11.0 será lançado.

@ Leen15

relevante do pod com falha:

  Warning  FailedCreatePodSandBox  3m (x5327 over 7h)  kubelet, nanopi-neo-plus2  (combined from similar events): Failed create pod sandbox: rpc error: code = Unknown desc = failed to set up sandbox container "9ddb551d520a757f4f8ff81d1dbfde50a98a5ec65385673a5a49a79e23a3243b" network for pod "arm-test-7894bfffd-njdcc": NetworkPlugin cni failed to set up pod "arm-test-7894bfffd-njdcc_default" network: open /run/flannel/subnet.env: no such file or directory

você está adicionando --pod-network-cidr=... que é necessário para a flanela?

experimente também este guia:
https://github.com/kubernetes/kubernetes/issues/36575#issuecomment -264622923

@ neolit123 sim, encontrei o problema: a flanela não criou a interface de rede virtual (cni e flannel0).
Não sei o motivo e não consegui resolvê-lo depois de várias horas.
Desisti e mudei para enxame.

OK entendido. nesse caso, estou encerrando o problema.
obrigado.

Também encontrei o mesmo problema, e descobri que o nó não consegue extrair as imagens necessárias por causa do GFW na China, então puxo as imagens manualmente e ele se recupera ok

Eu executei este comando e ele resolveu meu problema:

1. kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

Isso cria um arquivo no diretório /etc/cni/net.d com o nome de 10-flannel.conflist. Acredito que o kubernetes requer uma rede, que é definida por este pacote.

Oi Athir,

         Please check out logs in /var/logs/messages section of your Master node. You can find an actual error in those logs. But here are some general tips.

eu. Sempre concentre-se primeiro em seu nó mestre.
ii. Instale o docker engine nele e busque todas as imagens que estão sendo usadas para kubernetes. Quando tudo estiver em execução, adicione nós ao mestre. vai resolver todo o problema. Vi alguns artigos na internet que tentam buscar algumas imagens após anexar os nós escravos. Essa prática causa alguns problemas.

Oi saddique164, Obrigado por suas sugestões. Sim, como você disse, implantei outro nó escravo ontem e fui capaz de entrar no Master sem problemas.

Desculpe, não posso ajudar, não tenho mais nós ARM64, agora tenho um cluster AMD64 de 4 nós bare-metal.

O arquivo /etc/cni/net.d/10-flannel.conflist estava sem a chave cniVersion em sua configuração.

Adicionar "cniVersion": "0.2.0" resolveu o problema.

a flanela não é mantida de maneira muito ativa. eu recomendo chita ou weavenet.

o repositório de flanela precisava de uma correção.
o guia kubeadm para instalação de flanela acabou de ser atualizado, consulte:
https://github.com/kubernetes/website/pull/16575/files

Enfrentou o mesmo problema aqui.
kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml.

Funcionou para mim.

docker: plugin de rede não está pronto: cni config uninitialized

Reinstale o docker no nó não pronto.
Funcionou para mim.

Eu executei este comando e ele resolveu meu problema:

1. kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

Isso cria um arquivo no diretório /etc/cni/net.d com o nome de 10-flannel.conflist. Acredito que o kubernetes requer uma rede, que é definida por este pacote.
Meu cluster está no seguinte estado:

k8s-master Ready master 3h37m v1.14.1
node001 Ready 3h6m v1.14.1
node02 Ready 167m v1.14.1

Isso simplesmente fez isso!

Tive um caso semelhante em que estava criando o plug-in de rede antes de vincular os trabalhadores, o que manteve o /etc/cni/net.d ausente.
Executei novamente a configuração após vincular os nós de trabalho usando:
kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
Como resultado, a configuração em /etc/cni/net.d foi criada com sucesso e o nó mostrou um estado Pronto.

Espero que ajude alguém com o mesmo problema.

A maneira mais rápida é adicionar flanela ao Kubernetes na arquitetura AMD64.

1. Atualize kube-flannel.yaml

$ curl https://rawgit.com/coreos/flannel/master/Documentation/kube-flannel.yml \
> kube-flannel.yaml

2. Concluir a configuração da rede de flanela

$ kubectl apply -f kube-flannel.yaml

Estou usando a versão 1.18 do kubernetes.

Eu usei este: kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

Nenhum arquivo foi criado em /etc/cni/net.d
O nó mestre é NotReady, enquanto os escravos estão no estado Pronto

1. você pode executar o comando kubectl no mestre?
2. você pode verificar se o seu kubelet está sendo executado no mestre? ou execute: systemctl restart kubelet.
3. se o kubelet estiver reiniciando ou reiniciando automaticamente, execute o journal -u kubelet e verifique os logs. Você encontrará o erro.

NOTA: Este parece ser um problema de kubelet.

1. Sim, posso executar comandos kubectl.
2. Kubectl é executado e depois falha.
3. Isso é o que vejo nos erros de journactl -u kubelet:

tente isso no mestre:

sed -i 's / cgroup-driver = systemd / cgroup-driver = cgroupfs / g' /usr/lib/systemd/system/kubelet.service.d/10-kubeadm.conf

Ele começa e depois falha novamente.

Quantos nós estão em execução para você? NO cluster? um nó está fazendo esse problema. Isso é chamado de daemonset. Eles são executados em todos os nós. Seu plano de controle não está aceitando a solicitação dele. Portanto, vou sugerir que você siga os seguintes passos.

1. primeiro drene os nós de trabalho um por um.
   Nome do nó de drenagem Kubectl
2. em seguida, exclua-os.
   kubectl delete node nodename
3. aguarde até que o nó mestre esteja pronto. se não vier. execute este comando.
   kubeadm reset
4. novamente inicialize o kubeadm
   kubeadm init
5. execute este comando
   kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
6. obtenha o comando do mestre e execute-o nos nós de trabalho para conectá-los.

Este processo funcionará.

kubectl get nodes:

slave2   Ready      <none>   26h   v1.18.5

Tentei as etapas que você mencionou:

Isso é o que eu ganho.

        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)

        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.

        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'

To see the stack trace of this error execute with --v=5 or higher

drene todos os nós, exceto o mestre e concentre-se nisso. Quando estiver pronto, vá para adicionar outros.

Drenar nós e, em seguida, redefinir kubeadm e init não ajuda. O cluster não é inicializado posteriormente.

Meu problema era que eu estava atualizando o nome do host depois que o cluster foi criado. Ao fazer isso, é como se o mestre não soubesse que era o mestre.

Eu ainda estou correndo:

sudo hostname $(curl 169.254.169.254/latest/meta-data/hostname)

mas agora eu o executo antes da inicialização do cluster
