Can't see node after joining it to cluster - "getsockopt: connection refused" - docker
I am new in Kubernetes.
I have two nodes:
Master
Worker
I installed Kubernetes on both of them and on the muster I ran the kubeadm init... command in the Master node and received the command to join a new worker to the cluster:
sudo kubeadm join --token 61a503.3bdf2341a37a2732 192.168.190.159:6443 --discovery-token-ca-cert-hash sha256:ef66d8b7284af9e80f18767af39b5f164e00fd7fe714d3092e8ff682f07076da
I ran the above command inside the Worker node and it seems that it succeed:
This is the output:
[preflight] Running pre-flight checks.
[WARNING FileExisting-crictl]: crictl not found in system path
[discovery] Trying to connect to API Server "192.168.190.159:6443"

[discovery] Successfully established connection with API Server "192.168.190.159:6443"
This node has joined the cluster:
* Certificate signing request was sent to master and a response
was received.
* The Kubelet was informed of the new secure connection details.
Run 'kubectl get nodes' on the master to see this node join the cluster.
But when I go to the Master and run:
kubectl get nodes
I see only the master:
master#osboxes:~$ kubectl get nodes
NAME STATUS ROLES AGE VERSION
osboxes Ready master 4h v1.9.1
Docker version on both nodes:
Client:

How can I find what is the problem?
Any idea what can it be ?
By the way, I tried the same thing on two nodes in AWS and it worked fine.
EDIT (15.5.2018): Logs
These are the logs from the kubelet daemon from the Worker node, I exported it with sudo journalctl -u kubelet > logs.txt

error reading /var/lib/kubelet/pki/kubelet.key, certificate and key must be supplied as a pair
Usually, this is a permission issue. Check permissions of the certificate file, it should be readable for Kubelet user.
If it does not help you - please share the Kubelet logs, namely the logs of the daemon, do not start it manually in the console.
Based on the update of the question:
192.168.190.159:6443: getsockopt: connection refused
It means that Kubelet on the node cannot connect to the master. Check the network connection between your node and the master. The node should be able to connect to https://192.168.190.159:6443, which is your API server endpoint.
OK, the problem was that both nodes (Master and Worker) had the same hostname :).
I noticed it after I ran kubectl describe node and in the Addresses field I saw the IP address of the worker with the same Hostname of the master:
Addresses:
InternalIP: 192.168.190.162
Hostname: worker2node
I run sudo kubeadm reset on both Master and Worker.
On Master:
sudo swapoff -a
sudo kubeadm init --pod-network-cidr=10.244.0.0/16 --apiserver-advertise-address=192.168.190.159
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
kubectl apply -f kube-flannel.yml
On Worker:
Changed the hostname:
hostnamectl set-hostname worker2node
sudo vi /etc/hosts # (edit this file with the new name for 127.0.1.1)
Restart the worker and join it again.
I checked and now it was added.

kubeadm init failing on ARM64
I'm trying to setup a single master cluster on some sopine64s (quad A53 with 2GB RAM) running Armbian 5.38 (Ubuntu 16.04 based). Kernel is 3.10.107-pine64.
Steps taken so far:
usual ip address, hostname, timezone, dns, etc config
apt upgrade
disable swap
set net.bridge.bridge-nf-call-iptables to 1 in sysctl.conf (intending to use weavenet)
install docker 1.13.1 (docker.io package)
install kubeadm, kubelet, kubectl v1.11
systemctl enable and start kubelet and docker
reboot
kubeadm config images pull (all download ok)
Here's the output of kubeadm init:

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-arm64:v1.11.0
- k8s.gcr.io/kube-controller-manager-arm64:v1.11.0
- k8s.gcr.io/kube-scheduler-arm64:v1.11.0
- k8s.gcr.io/etcd-arm64:3.2.18
- 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
If I look at the containers, the one for kube-apiserver is exiting and being recreated every few minutes. Here's it's log file:
Flag --insecure-port has been deprecated, This flag will be removed in a future version.

Apologies for what may seem like a dump of log files, but any help is appreciated.
Did some more digging and apparently this is a known issue with bare metal kubeadm deployments on all versions above 1.9.6. I've been able to successfully run init by downgrading the version.
Disable ipv6 for docker in Ubuntu 14.04
I have an issue with the docker daemon installed on an Ubuntu 14.04 VM. The logs reveal that ipv6 is enabled hence the docker seems to be listening on this ip address. Essentially, this effects Clair. I have made sure that ipv6 is disabled on the following recommendation here. I also disabled ipv6 in daemon.json as specified in Docker documentation. My docker version is Docker version 17.06.1-ce, build 874a737.
Docker daemon logs :
time="2018-02-20T20:33:17.736203462+01:00" level=info msg="IPv6 enabled; Adding default IPv6 external servers: [nameserver 2001:4860:4860::8888 nameserver 20 01:4860:4860::8844]"
Clair logs:
2018/02/20 20:43:51 grpc: addrConn.resetTransport failed to create client transport: connection error: desc = "transport: Error while dialing dial tcp [::]:6060: connect: cannot assign requested address"; Reconnecting to {[::]:6060 <nil>}

It's trying to make an IPv6 connection, but the address is wrong. [::] is IN6ADDR_ANY, not an actual address you can connect to. Provide the correct address in your config.yaml. Did you mean to connect to localhost? api: # v3 grpc/RESTful API server address addr: "[::1]:6060"
Connection error when deploying chaincode
I just started using chaincode.
I am following step by step:
http://hyperledger-fabric.readthedocs.io/en/latest/Setup/Chaincode-setup/#running-the-chaincode
I am using Docker toolbox on Windows.
But when I start to run chaincode_example02, I get the following errors:
2016/09/15 14:05:53 grpc: addrConn.resetTransport failed to create client transport: connection error: desc = "transport: dial tcp 0.0.0.0:7051: connectex: The requested address is not valid in its context."; Reconnecting to {"0.0.0.0:7051" <nil>}

Why?
Docker getsockopt: connection refuse
I am running a docker server on my Ubuntu machine and I am getting an error when one of the application running into the server tries to open a socket, I get the following error, any clue why this is happening? I have run the same code in virtual box and I don't see it... Maybe a memory lack issue? thanks in adnvance, regards! croft_1 | 2016/04/15 13:55:03 Failed to connect: dial tcp 172.17.0.5:5672: getsockopt: connection refused croft_1 | 2016/04/15 13:55:05 Failed to connect: dial tcp 172.17.0.5:5672: getsockopt: connection refused croft_1 | 2016/04/15 13:55:07 Failed to connect: dial tcp 172.17.0.5:5672: getsockopt: connection refused croft_1 | 2016/04/15 13:55:09 Failed to connect: dial tcp 172.17.0.5:5672: getsockopt: connection refused croft_1 | 2016/04/15 13:55:11 Failed to connect: dial tcp 172.17.0.5:5672: getsockopt: connection refused croft_1 | 2016/04/15 13:55:13 Failed to connect: dial tcp 172.17.0.5:5672: getsockopt: connection refused croft_1 | 2016/04/15 13:55:15 Failed to connect: dial tcp 172.17.0.5:5672: getsockopt: connection refused croft_1 | 2016/04/15 13:55:17 Failed to connect: dial tcp 172.17.0.5:5672: getsockopt: connection refused croft_1 | 2016/04/15 13:55:19 Failed to connect: dial tcp 172.17.0.5:5672: getsockopt: connection refused croft_1 | 2016/04/15 13:55:21 Failed to connect: dial tcp 172.17.0.5:5672: getsockopt: connection refused croft_1 | 2016/04/15 13:55:23 Failed to connect: dial tcp 172.17.0.5:5672: getsockopt: connection refused croft_1 | 2016/04/15 13:55:25 Failed to connect: dial tcp 172.17.0.5:5672: getsockopt: connection refused croft_1 | 2016/04/15 13:55:27 Failed to connect: dial tcp 172.17.0.5:5672: getsockopt: connection refused croft_1 | 2016/04/15 13:55:29 Failed to connect: dial tcp 172.17.0.5:5672: getsockopt: connection refused croft_1 | 2016/04/15 13:55:31 Failed to connect: dial tcp 172.17.0.5:5672: getsockopt: connection refused croft_1 | 2016/04/15 13:55:33 Failed to connect: dial tcp 172.17.0.5:5672: getsockopt: connection refused croft_1 | 2016/04/15 13:55:35 Failed to connect: dial tcp 172.17.0.5:5672: getsockopt: connection refused croft_1 | 2016/04/15 13:55:37 Failed to connect: dial tcp 172.17.0.5:5672: getsockopt: connection refused croft_1 | 2016/04/15 13:55:39 Failed to connect: dial tcp 172.17.0.5:5672: getsockopt: connection refused croft_1 | 2016/04/15 13:55:41 Failed to connect: dial tcp 172.17.0.5:5672: getsockopt: connection refused croft_1 | panic: runtime error: invalid memory address or nil pointer dereference croft_1 | [signal 0xb code=0x1 addr=0x20 pc=0x401570] CONTAINER CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O PIDS 3b4a7e9023ad 0.00% 7.741 MB / 1.039 GB 0.74% 9.314 kB / 5.679 kB 5.046 MB / 0 B 0 6614c0b5c616 0.02% 4.379 MB / 1.039 GB 0.42% 10.02 kB / 648 B 5.009 MB / 0 B 0 658988a96412 3.09% 77.4 MB / 1.039 GB 7.45% 9.83 kB / 648 B 46.69 MB / 17.5 MB 0 9e1c772d7635 0.83% 115.7 MB / 1.039 GB 11.13% 15.12 kB / 5.484 kB 37.06 MB / 147.5 kB 0 0cc07e241f7a 0.22% 102.6 MB / 1.039 GB 9.87% 12.16 kB / 2.652 kB 37.25 MB / 471 kB 0 ^Clorabackbone#lorabackbone-desktop:~/server-devenv$ docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 3b4a7e9023ad serverdevenv_croft "./croft" 3 hours ago Up 2 minutes 1700/tcp, 0.0.0.0:1700->1700/udp serverdevenv_croft_1 6614c0b5c616 ansi/mosquitto "/usr/local/sbin/mosq" 3 hours ago Up 3 minutes 0.0.0.0:1883->1883/tcp serverdevenv_mosquitto_1 658988a96412 serverdevenv_mongodb "/entrypoint.sh mongo" 3 hours ago Up 3 minutes 0.0.0.0:27017->27017/tcp serverdevenv_mongodb_1 9e1c772d7635 rabbitmq:3-management "/docker-entrypoint.s" 3 hours ago Up 3 minutes 4369/tcp, 5671/tcp, 0.0.0.0:5672->5672/tcp, 15671/tcp, 25672/tcp, 0.0.0.0:15672->15672/tcp serverdevenv_rabbitmq_1 0cc07e241f7a cpswan/node-red "/usr/local/bin/node-" 3 hours ago Up 3 minutes 0.0.0.0:1880->1880/tcp
