Todos los nodos del estado Ready
.
Simplemente siga los pasos del tutorial . Intenté 3 veces y sucede todo el tiempo.
El maestro es ARM64, 2 nodos son AMD64.
El maestro y un nodo están en Ámsterdam y el segundo nodo está en los EE. UU.
Puedo usar kubectl taint nodes --all node-role.kubernetes.io/master-
para ejecutar pods en el maestro, pero esta no es una solución. Quiero tener un clúster de múltiples nodos real para trabajar.

No soy un experto en franela, pero creo que debería consultar la documentación del producto para saber cómo hacer que funcione en un entorno con plataformas mixtas.
Ese es un buen punto, pero ¿qué pasa con el mensaje de error? Parece que realmente no tiene relación.
runtime network not ready: NetworkReady=false reason:NetworkPluginNotReady message:docker: network plugin is not ready: cni config uninitialized
Parece que faltan algunos archivos de configuración CNI en /etc/cni/net.d
pero ¿por qué?
Ahora estoy probando una ventana acoplable diferente 18.03ce
como se sugiere en el canal de holgura (en realidad se sugirió 17.03, pero no hay 17.03 para Ubuntu 18.04).
Las etiquetas con el nombre del arco no coinciden. Pero la siguiente etiqueta beta.kubernetes.io/os=linux
es la misma en los 3 servidores.
Lo mismo ocurre con Docker 18.03ce. No veo ninguna diferencia, esto no parece un problema de Docker. Esto parece un problema de configuración de CNI.
@lukaszgryglicki
Hola,
Maestro: servidor bare metal 96 núcleos, ARM64, 128G RAM, intercambio desactivado.
Nodos (2): servidor bare metal de 48 núcleos, AMD64, 256G de RAM, intercambio sintonizado x 2.
estas son algunas especificaciones _ agradables_.
La forma en que pruebo las cosas es la siguiente: si algo no funciona con weavenet, pruebo la franela y al revés.
así que intente tejer y si su configuración CNI funciona con él, entonces esto está relacionado con el complemento CNI.
Si bien el equipo de kubeadm admite complementos y complementos, generalmente delegamos los problemas a sus respectivos mantenedores porque no tenemos el ancho de banda para manejar todo.
Claro, intenté tejer hace algunas iteraciones. Terminó en un ciclo de reinicio del contenedor.
Ahora probaré la ventana acoplable 17.03 para excluir el problema de la ventana acoplable (se supone que la versión 17.03 es muy buena).
Así que esto no es un problema de Docker. El 17.03 lo mismo:
Aug 02 14:21:51 devstats.cncf.io kubelet[21714]: W0802 14:21:51.406786 21714 cni.go:172] Unable to update cni config: No networks found in /etc/cni/net.d

now will try weave net as suggested on the issue
Intentaré tejer ahora y publicar los resultados aquí.
Entonces, probé weave net
y no funciona:

Entonces, resumiendo. Es imposible instalar el clúster de Kubernetes con un solo nodo maestro y un solo nodo trabajador en Ubuntu 18.04.
Creo que debería haber una instrucción de instalación sobre cómo configurar k8s paso a paso usando kubeadm en el Ubuntu LTS más nuevo.
Creo que 18.04 se rompió tanto en términos del Docker que incluye como por systemd-resolved
.
así que sí, es muy difícil escribir guías para cada sabor de distribución que existe y realmente no podemos mantenerlas de manera eficiente.
Además, aunque kubeadm es la interfaz aquí, el problema realmente podría no estar relacionado con kubeadm en sí.
algunas preguntas:
/var/lib/kubelet/kubeadm-flags.env
cuando empiezas kubeadm join/init
en los 3 nodos?journalctl -xeu kubelet
? ¿Eso es solo en el nodo maestro? ¿Qué pasa con los demás? puedes volcarlos en un github gist o en http://pastebin.com para que yo también mire.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
nodo (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
nodo (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
Entonces, instalé el maestro kubeadm init
en el host amd64 y probé weave net
y el resultado es exactamente el mismo que cuando probé esto en el host arm64:
runtime network not ready: NetworkReady=false reason:NetworkPluginNotReady message:docker: network plugin is not ready: cni config uninitialized
Hay un pequeño avance.
He instalado master en amd64 y luego un nodo en amd64 también. Todo funcionó bien.
Agregué el nodo arm64 y ahora tengo:
maestro amd64: listo
nodo amd64: listo
nodo arm64: NotReady: runtime network not ready: NetworkReady=false reason:NetworkPluginNotReady message:docker: network plugin is not ready: cni config uninitialized
flannel
net no puede hablar entre diferentes arquitecturas y arm64 no se puede usar como maestro en absoluto.runtime network not ready: NetworkReady=false reason:NetworkPluginNotReady message:docker: network plugin is not ready: cni config uninitialized
¿Alguna sugerencia que debo hacer? ¿Dónde debo informar de esto? Ya tengo un clúster de 2 nodos (maestro y nodo amd64) pero quiero ayudar a resolver este problema para poder usar cualquier arco maestro con cualquier arco nodo solo OOTB.
@lukaszgryglicki
kube-flannel.yml
implementa el contenedor de franela solo para una arquitectura. Esta es la razón por la que en nodos con arquitectura diferente, el complemento cni no se inicia y el nodo nunca se prepara
Nunca lo intenté por mí mismo, pero supongo que puede implementar dos manifiestos de franela pirateados con diferentes manchas (y nombres) para evitar mezclar las cosas, pero nuevamente, mi sugerencia es preguntarle a la gente de franela si ya hay instrucciones sobre cómo hacer esto. .
Pero modifiqué el manifiesto en arm64 como se sugiere en el tutorial. Reemplazó amd64
con arm64
.
Entonces, tal vez cree un problema para flannell
y pegue un enlace a este hilo.
¿Y ahora por qué wave net
falla en ambos arcos con el mismo error relacionado con cni? ¿Quizás crear un problema para weave
también y también vincular a este hilo?
@lukaszgryglicki
Cuando pulsaste kube-flannel.yml
para arm, deja de funcionar en máquinas amd ... Es por eso que supongo que la implementación de 2 manifiestos bien ajustados, uno para arm y otro para amd, puede resolver tu problema.
Y ahora que lo pienso, podría ser que debería solucionar el mismo problema con el conjunto de demonios kube-proxy, pero no puedo probar esto ahora, lo siento
Para el problema que tienes con el tejido, no tengo suficiente información. Un problema podría ser que el tejido no funciona con --pod-network-cidr=10.244.0.0/16
, pero volviendo al problema inicial, no sé de memoria si el tejido funciona desde el primer momento en plataformas mixtas o no.
Entonces debería implementar dos manifiestos diferentes de franela en un maestro, ¿verdad? No importa si master es arm64 o amd64, ¿verdad? ¿Debería Master manejar el despliegue correcto del arco en sí mismo y en los nodos?
No estoy seguro de a qué te refieres aquí:
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
No usé --pod-network-cidr=10.244.0.0/16
para weave
. He usado solo kubeadm init
.
He usado --pod-network-cidr=10.244.0.0/16
solo para intentos de franela. Como dicen los doctores.
cc @luxas : he visto que ha creado algunos documentos sobre implementaciones de k8s de múltiples arcos, ¿tal vez pueda tener algunos comentarios?
@lukasredynk
sí, después de todo, este es un problema archi, gracias por confirmar.
centrémonos en la franela aquí, ya que el tema del tejido parece tangente.
Eche un vistazo a esto de @luxas para el contexto, si aún no lo ha visto:
https://github.com/luxas/kubeadm-workshop
¿Debería Master manejar el despliegue correcto del arco en sí mismo y en los nodos?
_ debería_ pero el manifiesto que está descargando no es "gordo":
https://raw.githubusercontent.com/coreos/flannel/v0.10.0/Documentation/kube-flannel.yml
Por lo que tengo entendido, las manchas de arco se propagan y debe solucionarlo con kubectl
en cada nodo (?).
parece que un manifiesto "gordo" está en el maestro y se agregó aquí:
https://github.com/coreos/flannel/commit/c5d10c8b16d7c43bfa6e8408673c6d95404bd807#diff -7891b552b026259e99d479b5e30d31ca
problema relacionado / pr:
https://github.com/coreos/flannel/issues/663
https://github.com/coreos/flannel/pull/989
mi suposición es que esto es de vanguardia y tienes que usar:
kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
así que baja el clúster y pruébalo y espera que funcione.
nuestros documentos CNI necesitarían un aumento, sin embargo, esto debe suceder cuando se publique flannel-next
.
Bien, lo intentaré después del fin de semana y publicaré mis resultados aquí. Gracias.
@lukaszgryglicki hola, ¿conseguiste que esto funcionara usando el nuevo manifiesto de franela?
Todavía no, lo intentaré hoy.
OK finalmente funcionó:

rama ayudó.

Hola chicos, estoy en la misma situación.
Tengo nodos de trabajo en estado Listo, pero la franela en arm64 sigue fallando con este error:
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, ¿te funcionó?
¿alguna idea?
El error parece diferente, pero ¿usó el manifiesto gordo: https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml ?
Contiene manifiestos para múltiples arcos.
Sí lo soy:
El problema ahora es el recipiente de franela que no se mantiene en el brazo. :(
lo hace en amd64
y arm64
- funciona para mí.
Desafortunadamente, no puedo ayudar con arm
(32 bits), no tengo una máquina arm
disponible.
Estoy en arm64 pero gracias, seguiré investigando ...
Ohh, entonces lo siento, pensé que estabas del brazo.
De todos modos, también soy bastante nuevo en esto, así que debes esperar a que otros chicos te ayuden.
Pegue la salida de kubectl describe pods --all-namespace
y la posible salida de otros comandos que publiqué en este hilo. Esto puede ayudar a alguien a rastrear el problema real.
Gracias @lukaszgryglicki ,
esta es la salida de describe pods: https://pastebin.com/kBVPYsMd
@lukaszgryglicki
Me alegro de que funcionó al final.
Documentaré el uso del manifiesto gordo para la franela en los documentos, ya que no tengo idea de cuándo se lanzará 0.11.0.

@ neolit123 sí, encontré el problema: flannel no creó la interfaz de red virtual (cni y flannel0).
No sé el motivo y no pude resolverlo después de varias horas.
Me di por vencido y cambié a enjambre.
entendido. en ese caso estoy cerrando el tema.
Gracias.
También me encontré con el mismo problema, y descubrí que el nodo no puede extraer las imágenes requeridas debido al GFW en China, así que extraigo las imágenes manualmente y se recupera bien
Ejecuté este comando y resolvió mi problema:
Esto crea un archivo en el directorio /etc/cni/net.d con el nombre de 10-flannel.conflist. Creo que kubernetes requiere una red, que está configurada por este paquete.

Hola 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.
I. Concéntrese siempre primero en su nodo maestro.
ii. Instale el motor de la ventana acoplable y obtenga todas las imágenes que se están utilizando para kubernetes. Cuando todo esté en ejecución, agregue nodos al maestro. Resolverá todo el problema. Vi algunos artículos en Internet, que intentan obtener algunas imágenes después de adjuntar los nodos esclavos. Esa práctica causa algunos problemas.
Hola saddique164, Gracias por tus sugerencias. Sí, como dijiste, ayer implementé otro nuevo nodo esclavo y pude unirme al Maestro sin ningún problema.
Lo siento, no puedo ayudar, ya no tengo nodos ARM64, ahora tengo un clúster puro AMD64 de 4 nodos.
Al archivo /etc/cni/net.d/10-flannel.conflist le faltaba la clave cniVersion en su configuración.
Agregar "cniVersion": "0.2.0" resolvió el problema.

la franela no se mantiene muy activamente. recomiendo calico o weavenet.
el depósito de franela necesitaba una reparación.
la guía de kubeadm para instalar franela se acaba de actualizar, consulte:
https://github.com/kubernetes/website/pull/16575/files
Enfrenté el mismo problema aquí.
kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml.
Trabajó para mi.
docker: el complemento de red no está listo: cni config sin inicializar
Vuelva a instalar la ventana acoplable en el nodo que no está listo.
Trabajó para mi.
Ejecuté este comando y resolvió mi problema:
- kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
Esto crea un archivo en el directorio /etc/cni/net.d con el nombre de 10-flannel.conflist. Creo que kubernetes requiere una red, que está configurada por este paquete.
Mi clúster está en el siguiente estado:NOMBRE ESTADO ROLES EDAD VERSIÓN
k8s-master Ready master 3h37m v1.14.1
node001 Listo 3h6m v1.14.1
node02 Ready 167m v1.14.1
¡Eso acaba de hacerlo!
Tuve un caso similar en el que estaba creando el complemento de red antes de vincular a los trabajadores, lo que hacía que faltara /etc/cni/net.d.
Re-ejecuté la configuración después de vincular los nodos trabajadores usando:
kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
Como resultado, la configuración en /etc/cni/net.d se creó con éxito y el nodo se mostró en estado Listo.
Espero que ayude a cualquiera con el mismo problema.

La forma más rápida es agregar Flannel a Kubernetes en cualquiera de las arquitecturas AMD64.
$ curl https://rawgit.com/coreos/flannel/master/Documentation/kube-flannel.yml \
> kube-flannel.yaml
$ kubectl apply -f kube-flannel.yaml
Estoy usando la versión de kubernetes 1.18.
Usé esto: kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
No se creó ningún archivo en /etc/cni/net.d
El nodo maestro no está listo mientras que los esclavos están en estado Listo

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'
error execution phase wait-control-plane: couldn't initialize a Kubernetes cluster
To see the stack trace of this error execute with --v=5 or higher
drene todos los nodos excepto el maestro y concéntrese en eso. Cuando esté listo, vaya a agregar otros.
Drenar los nodos y luego kubeadm reset e init no ayuda. El clúster no se inicializa posteriormente.
Mi problema fue que estaba actualizando el nombre de host después de que se creó el clúster. Al hacer eso, es como si el maestro no supiera que era el maestro.
Todavía estoy corriendo:
sudo hostname $(curl 169.254.169.254/latest/meta-data/hostname)
pero ahora lo ejecuto antes de la inicialización del clúster
Comentario más útil
@lukasredynk
sí, después de todo, este es un problema archi, gracias por confirmar.
centrémonos en la franela aquí, ya que el tema del tejido parece tangente.
Eche un vistazo a esto de @luxas para el contexto, si aún no lo ha visto:
https://github.com/luxas/kubeadm-workshop
_ debería_ pero el manifiesto que está descargando no es "gordo":
https://raw.githubusercontent.com/coreos/flannel/v0.10.0/Documentation/kube-flannel.yml
Por lo que tengo entendido, las manchas de arco se propagan y debe solucionarlo con
kubectl
en cada nodo (?).parece que un manifiesto "gordo" está en el maestro y se agregó aquí:
https://github.com/coreos/flannel/commit/c5d10c8b16d7c43bfa6e8408673c6d95404bd807#diff -7891b552b026259e99d479b5e30d31ca
problema relacionado / pr:
https://github.com/coreos/flannel/issues/663
https://github.com/coreos/flannel/pull/989
mi suposición es que esto es de vanguardia y tienes que usar:
así que baja el clúster y pruébalo y espera que funcione.
nuestros documentos CNI necesitarían un aumento, sin embargo, esto debe suceder cuando se publique
flannel-next
.
