QUESTION

Kubernetes access to port on node from inside pod?

Asked 2021-Jun-07 at 06:23

I am trying to access a service listening on a port running on every node in my bare metal (Ubuntu 20.04) cluster from inside a pod. I can use the real IP address of one of the nodes and it works. However I need pods to connect to the port on their own node. I cant use '127.0.0.1' inside a pod.

More info: I am trying to wrangle a bunch of existing services into k8s. We use an old version of Consul for service discovery and have it running on every node providing DNS on 8600. I figured out how to edit the coredns Corefile to add a consul { } block so lookups for .consul work.

It is possible that you need to patch the CoreDNS deployment. By default it is configured to only run on worker nodes and not on Fargate. See the "(Optional) Update CoreDNS" section in this doc page

Flannel does not support NFT, and since you are using CentOS 8, you can't fallback to iptables.
Your best bet in this situation would be to switch to Calico.
You have to update Calico DaemonSet with:

The reason for your issues is that the TLS connection between the components has to be secured. From the kubelet point of view this will be safe if the Api-server certificate will contain in alternative names the IP of the server that we want to connect to. You can notice yourself that you only add to SANs one IP address.

How can you fix this? There are two ways:

Use the --discovery-token-unsafe-skip-ca-verification flag with your kubeadm join command from your node.
Add the IP address from the second NIC to SANs api certificate at the cluster initialization phase (kubeadm init)

QUESTION

Kube-Proxy-Windows CrashLoopBackOff

Asked 2021-May-07 at 12:21

Installation Process

I am all new to Kubernetes and currently setting up a Kubernetes Cluster inside of Azure VMs. I want to deploy Windows containers, but in order to achieve this I need to add Windows worker nodes. I already deployed a Kubeadm cluster with 3 master nodes and one Linux worker node and those nodes work perfectly.

Once I add the Windows node all things go downward. Firstly I use Flannel as my CNI plugin and prepare the deamonset and control plane according to the Kubernetes documentation: https://kubernetes.io/docs/tasks/administer-cluster/kubeadm/adding-windows-nodes/

Then after the installation of the Flannel deamonset, I installed the proxy and Docker EE accordingly.

Used Software Master Nodes

OS: Ubuntu 18.04 LTS
Container Runtime: Docker 20.10.5
Kubernetes version: 1.21.0
Flannel-image version: 0.14.0
Kube-proxy version: 1.21.0

Windows Worker Node

OS: Windows Server 2019 Datacenter Core
Container Runtime: Docker 20.10.4
Kubernetes version: 1.21.0
Flannel-image version: 0.13.0-nanoserver
Kube-proxy version: 1.21.0-nanoserver

Wanted Results:

I wanted to see a full cluster ready to use and with all the needed in the Running state.

Are you still having this error? I managed to fix this by downgrading windows kube-proxy to at least 1.20.0. There must be some missing config or bug for 1.21.0.

As already discussed in the comments the Ingress Controller will be created in the ingress-nginx namespace instead of the kube-system namespace. Other than that the rest of the tutorial should work as expected.

Can't resolve dns in kubernetes

...

ANSWER

Answered 2021-May-07 at 06:40

Finally, I find the root cause, this is hardware firewall issue, see this:

Firewalls
When using udp backend, flannel uses UDP port 8285 for sending encapsulated packets.
When using vxlan backend, kernel uses UDP port 8472 for sending encapsulated packets.
Make sure that your firewall rules allow this traffic for all hosts participating in the overlay network.
Make sure that your firewall rules allow traffic from pod network cidr visit your kubernetes master node.

When nslookup client on the same node of dns server, it won't trigger firewall block, so everything is ok.
When nslookup client not on the same node of dns server, it will trigger firewall block, so we can't access dns server.

So, after open the ports, everything ok now.
