This content is associated with a legacy version of the Replicated product. For the current Replicated product documentation, see docs.replicated.com.
We distribute an installation script that can be used to install Docker, Kubernetes and Replicated. The cluster should not be created prior to running the install script. The Replicated install script will install a working Kubernetes cluster.
The basic install will install Docker, Kubernetes and Replicated. It will save the install script to a file which you can inspect and then run. We recommend reading and understanding the install script prior to running.
curl -sSL -o install.sh https://get.replicated.com/kubernetes-init sudo bash ./install.sh
The quick Kubernetes install will install Docker, Kubernetes and Replicated. Use this method if you have no need to view/change the installer script and you just want a one-line install.
curl -sSL https://get.replicated.com/kubernetes-init | sudo bash
The install script can take flags to help your customers with specialized enterprise setups.

Example quick install with flags:
curl -sSL https://get.replicated.com/kubernetes-init | \ sudo bash -s no-proxy ui-bind-port=8000
Every release of Replicated is pinned to a version of Kubernetes, which will be installed by the install script.
|Replicated Version||Kubernetes Version|
|2.26.0 to 2.30.2||1.11.5|
|2.31.0 to 2.37.1||1.13.5|
Replicated 2.26.0 to 2.30.2 were pinned to Kubernetes 1.11.1 when released but were updated on December 7, 2018 to 1.11.5.
Replicated 2.31.0 to 2.34.1 were pinned to Kubernetes 1.13.0 when released, and airgap bundles from 2.31.0 to 2.34.1 include 1.13.0.
Replicated 2.38.0 was pinned to Kubernetes 1.15.0 when released and the 2.38.0 airgap bundle includes 1.15.0.
kubernetes-init install script will not update patch versions by default, but the upgrade can be forced by passing the
kubernetes-upgrade-patch-version flag to the script.
Please refer to our docs on upgrading here
Replicated Embedded Kubernetes has the ability to run in highly available mode with multiple Kubernetes control plane nodes. The addition of the
ha flag when running the Kubernetes easy-install script signals to Replicated that this cluster should be run in HA mode. For more information please refer to our docs on high availability clusters here.
curl -sSL -o install.sh https://get.replicated.com/kubernetes-init sudo bash ./install.sh ha
reset flag to uninstall Kubernetes and Replicated. Please note that this flag is not recommended to be used on production systems.
curl -sSL https://get.replicated.com/kubernetes-init | sudo bash -s reset
The procedure described in this post can be used to reset Replicated back to the state where license can be uploaded again without removing Kubernetes. This is a safer option.
