The Replicated installation script can be used to install Docker and Kubernetes in an airgapped environment, and not install Replicated to the cluster. This is useful when you want to use another method to distribute your application, such as The Getting Started Guide.
Basic install (recommended):
The basic install will install Docker, Kubernetes by pulling the scripts and resources from the Internet. 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 -s kubernetes-only
Quick Install
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 -s kubernetes-only
Flags
The install script can take flags to help your customers with specialized enterprise setups.

Kubernetes Only In Airgapped Environments
The airgap package can be installed by downloading the latest release from https://s3.amazonaws.com/replicated-airgap-work/replicated__docker__kubernetes.tar.gz and running the following commands:
tar xzvf replicated__docker__kubernetes.tar.gz
cat ./kubernetes-init.sh | sudo bash -s airgap kubernetes-only
