This article mainly introduces Ubuntu 18.04 LTS how to install Kubernetes 1.11, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to know about it.

Here comes the combination of Ubuntu 18.04 + Kuberntes 1.11.2 + Istio 1.0.

For complete installation instructions, refer to:

Https://linuxconfig.org/how-to-install-kubernetes-on-ubuntu-18-04-bionic-beaver-linux

Other details of the installation are resolved:

Container GPU support is required. Refer to:

Http://Kubernetes installs GPU support plug-ins

Service Grid Istio installation, refer to:

Quick installation of Istio 1.0to the Kubernetes cluster

Script resources related to installation tools:

Https://github.com/openthings/kubernetes-tools

Install Docker# preparation software source sudo apt install docker.iosudo systemctl enable docker

Install Docker-CE

Add key:

Https_proxy=192.168.199.249:30999 wget https://download.docker.com/linux/ubuntu/gpg-O docker.keysudo apt-key add docker.key

Add source

Sudo echo "deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic edge" > / etc/apt/sources.list.d/docker.listsudo apt updatesudo apt install docker-ce

Make sure that the cgroup driver used by kubelet is consistent with Docker. Or update the Docker using the following method:

Cat / etc/docker/daemon.json {"exec-opts": ["native.cgroupdriver=systemd"]} EOF

Then restart the Docker service and run:

Sudo systemctl daemon-reloadsudo systemctl restart dockerKuberntes 1.11.2 installation

Follow these steps:

Curl-s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key addsudo apt-add-repository "deb http://apt.kubernetes.io/ kubernetes-xenial main" # install basic support software sudo apt install kubeadm kubectl kubelet# turn off disk exchange sudo swapoff-a # clear firewall settings sudo iptables-F# set domain name sudo hostnamectl set-hostname kubernetes-master# initialization environment, note that this version number must be specified (otherwise it will hang). # specifies that CoreDNS is used as the name service. If you don't specify-- feature-gates CoreDNS=true, the default kubedns service is used. Sudo kubeadm init-- kubernetes-version=v1.11.2-- pod-network-cidr=10.244.0.0/16-- feature-gates CoreDNS=true# specifies the IP address Version 1.12.2: # sudo kubeadm init-- kubernetes-version=v1.12.2-- apiserver-advertise-address=10.1.1.201-- pod-network-cidr=10.244.0.0/16-- feature-gates CoreDNS=true# creates a user profile mkdir-p $HOME/.kubekubernetes-master:~$ sudo cp-I / etc/kubernetes/admin.conf $HOME/.kube/configkubernetes-master:~$ sudo chown $(id-u): $(id-g) $HOME/.kube/config# Security Install the network kubectl apply-f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml# and enable the master computer to view the result kubectl get pods-- all-namespaces as the working node kubectl taint nodes-- all node-role.kubernetes.io/master-#

!!! However, there are two problems:

At present, kubernetes does not have a compiled version of Ubuntu18.04, which uses 16.04 xenial binaries.

The key of the above cloud.google will make an error, use the following method to get:

Sudo apt-key adv-keyserver hkp://keyserver.ubuntu.com:80-recv-keys 6A030B21BA07F4FB

Then perform the sudo apt update and the installation steps that follow.

!!! There is a pending hang problem when installing the flannel network (the podCidr parameter is missing, even if it is specified when kubeadm is running): # View the log: kubectl get pods-- namespace kube-systemkubectl-- the kube-flannel-ds-bvxd2 above namespace kube-system logs kube-flannel-ds-bvxd2# is the pod name of flannel. Enter according to the name returned by get pods. # Edit / etc/kubernetes/manifests/kube-controller-manager.yaml in the command section, add:-- allocate-node-cidrs=true- cluster-cidr=10.244.0.0/16 and then system restart kubelet.

Detailed reference for the solution to the problem: https://github.com/coreos/flannel/issues/728

Install Helm and Dashboard

Reference:

Kubernetes Dashboard panel service installation, https://my.oschina.net/u/2306127/blog/1606599

Dashboard installation authorization login details reference, https://my.oschina.net/u/2306127/blog/1630861

Helm package Management Service installation, https://my.oschina.net/u/2306127/blog/1619818

Notice that you use sudo https_proxy=127.0.0.1:9999 helm init-- service-account tiller to add repo (you need to access gcr, but proxy makes it impossible to access the local cluster port), and then run helm init-- service-account tiller again (add helm tiller pod to the cluster).

Pull the container image in advance

At present, the latest version of kubernetes is 1.11.2, which can be pulled from the mirror library I made:

Save the above as a script file and run it.

Then run kubeadm init to initialize the cluster.

Then install Istio 1.0

Kubenetes service does not start problem

After restarting the system, if you find that the kubelet service is not up, first check:

Nano / etc/fstab# comment out the swap line inside.

Finally, add the KUBELET_CGROUP_ARGS and KUBELET_EXTRA_ARGS parameters to the / etc/systemd/system/kubelet.service.d/10-kubeadm.conf file, and note that you should also add the startup parameters as follows:

Environment= "KUBELET_CGROUP_ARGS=--cgroup-driver=systemd" Environment= "KUBELET_EXTRA_ARGS=--fail-swap-on=false" ExecStart=ExecStart=/usr/bin/kubelet $KUBELET_KUBECONFIG_ARGS $KUBELET_SYSTEM_PODS_ARGS $KUBELET_NETWORK_ARGS $KUBELET_DNS_ARGS $KUBELET_AUTHZ_ARGS $KUBELET_CADVISOR_ARGS $KUBELET_CERTIFICATE_ARGS $KUBELET_CGROUP_ARGS $KUBELET_EXTRA_ARGS! Then restart the kubelet service and run: systemctl daemon-reloadsystemctl restart kubelet thanks you for reading this article carefully. I hope the article "Ubuntu 18.04 LTS how to install Kubernetes 1.11" shared by the editor will be helpful to you. At the same time, I also hope you will support us and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
