CONVOY PLUGIN ODKCER HOW TO

You can leave SELinux enabled if you know how to configure it but it may require settings that are not supported by kubeadm. You have to do this until SELinux support is improved in the kubelet. This is required to allow containers to access the host filesystem, which is needed by pod networks for example. Setting SELinux in permissive mode by running setenforce 0 and sed.

Sudo yum install -y kubelet kubeadm kubectl -disableexcludes =kubernetes For example, the kubelet running 1.7.0 should be fully compatible with a 1.8.0 API server,įor information about installing kubectl, see Install and set up kubectl.Ĭat < convoy plugin odkcer

Kubelet and the control plane is supported, but the kubelet version may never exceed the API However, one minor version skew between the If you do not, there is a risk of a version skew occurring thatĬan lead to unexpected, buggy behaviour. Need to ensure they match the version of the Kubernetes control plane you want Kubeadm will not install or manage kubelet or kubectl for you, so you will Kubectl: the command line util to talk to your cluster. Kubelet: the component that runs on all of the machines in your clusterĪnd does things like starting pods and containers. Kubeadm: the command to bootstrap the cluster. You will install these packages on all of your machines: You can use tools like netcat to check if a port is open. Need to be open in order for Kubernetes components to communicate with each other. Route, we recommend you add IP route(s) so Kubernetes cluster addresses go via the appropriate adapter. If you have more than one network adapter, and your Kubernetes components are not reachable on the default If these values are not unique to each node, the installation process Kubernetes uses these values to uniquely identify the nodes in the cluster. It is very likely that hardware devices will have unique addresses, although some virtual machines may have

The product_uuid can be checked by using the command sudo cat /sys/class/dmi/id/product_uuid.

You can get the MAC address of the network interfaces using the command ip link or ifconfig -a.

Verify the MAC address and product_uuid are unique for every node

You MUST disable swap in order for the kubelet to work properly. Certain ports are open on your machines.Unique hostname, MAC address, and product_uuid for every node.

Full network connectivity between all machines in the cluster (public or private network is fine).

2 GB or more of RAM per machine (any less will leave little room for your apps).

The Kubernetes project provides generic instructions for Linux distributions based on Debian and Red Hat, and those distributions without a package manager. This page shows how to install the kubeadm toolbox.įor information on how to create a cluster with kubeadm once you have performed this installation process, see the Creating a cluster with kubeadm page.
