Node components
Nodes in the cluster need a couple of components to interact with the cluster master components, receive workloads to execute, and update the cluster on their status.
How to install specific version of Kubernetes?
I install the latest version of Kubernetes with the following command on Raspberry PI 3 running Raspbian Stretch.
$ curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add - && echo "deb http://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubernetes.list && sudo apt-get update -q && sudo apt-get install -qy kubeadm
Currently this will install v1.10.0.
How can I install a specific version of Kubernetes? Let's say v1.9.6.
BEST ANSWER:
To install specific version of the package it is enough to define it during the apt-get install command:
apt-get install -qy kubeadm=<version>
But in the current case kubectl and kubelet packages are installed by dependencies when we install kubeadm, so all these three packages should be installed with a specific version:
$ curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add - && echo "deb http://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubernetes.list && sudo apt-get update -q && sudo apt-get install -qy kubelet=<version> kubectl=<version> kubeadm=<version>
where available <version> is:
curl -s https://packages.cloud.google.com/apt/dists/kubernetes-xenial/main/binary-amd64/Packages | grep Version | awk '{print $2}'
For your particular case it is:
$ curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add - && echo "deb http://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubernetes.list && sudo apt-get update -q && sudo apt-get install -qy kubelet=1.9.6-00 kubectl=1.9.6-00 kubeadm=1.9.6-00
Act as if what you do makes a difference. It does.
