-Script for Setting Up 1-node Kubernetes Cluster
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The it/dep repo can be used for generating a simple script that can help setting up a
-one-node Kubernetes cluster for dev and testing purposes. Related files are under the
-**tools/k8s/bin** directory. Clone the repository on the target VM:
-
-::
-
- % git clone https://gerrit.o-ran-sc.org/r/it/dep
-
-
-Configurations
-^^^^^^^^^^^^^^
-
-The generation of the script reads in the parameters from the following files:
-
-- etc/env.rc: Normally no change needed for this file. If where the Kubernetes cluster runs
- has special requirements, such as running private Docker registry with self-signed certificates,
- or hostnames that can be only resolved via private /etc/hosts entries, such parameters are
- entered into this file.
-- etc/infra.rc: This file specifies the docker host, Kubernetes, and Kubernetes CNI versions.
- If a version is left empty, the installation will use the default version that the OS package
- management software would install.
-- etc/openstack.rc: If the Kubernetes cluster is deployed on Open Stack VMs, this file specifies
- parameters for accessing the APIs of the Open Stack installation. This is not supported in Amber
- release yet.
-
-
-Generating Set-up Script
-^^^^^^^^^^^^^^^^^^^^^^^^
-
-After the configurations are updated, the following steps will create a script file that can be
-used for setting up a one-node Kubernetes cluster. You must run this command on a Linux machine
-with the 'envsubst' command installed.
-
-::
-
- % cd tools/k8s/bin
- % ./gen-cloud-init.sh
-
-A file named **k8s-1node-cloud-init.sh** would now appear under the bin directory.
-
-
-Setting up Kubernetes Cluster
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The new **k8s-1node-cloud-init.sh** file is now ready for setting up the Kubernetes cluster.
-
-It can be run from a root shell of an existing Ubuntu 16.04 or 18.04 VM. Running this script
-will replace any existing installation of Docker host, Kubernetes, and Helm on the VM. The
-script will reboot the machine upon successful completion. Run the script like this:
-
-::
-
- % sudo -i
- # ./k8s-1node-cloud-init.sh
-
-This script can also be used as the user-data (a.k.a. cloud-init script) supplied to Open Stack
-when launching a new Ubuntu 16.04 or 18.04 VM.
-
-Upon successful execution of the script and reboot of the machine, when queried in a root shell
-with the kubectl command the VM should display information similar to below:
-
-::
-
- # kubectl get pods --all-namespaces
- NAMESPACE NAME READY STATUS RESTARTS AGE
