Introduction

we will deploy a microk8s in linux(ubuntu - 18.04)/MacOs(not tested)and will create the docker image and push it local registry and deploy the same docker in microk8s kube.

Pre-requisites

Before we get started using the script.

• Ensure you have installed docker.
• Snap need to be installed.
• Python need to be installed.

Installation/commands

1. Below command will install microk8s and enabled dns,dashboard and registry

python ./simple_kube.py --install kube

2. Varies command to stop,start and check the status of microk8s.

python ./simple_kube.py --start/stop/status kube

3. List the pods running in microk8s

python ./simple_kube.py --list-pods kube

4. List the deployment running in microk8s

python ./simple_kube.py --list-deployment kube

5. Below command will create the deployment in microk8s.

python ./simple_kube.py --create-deployment <yaml_path>

6. Below command will create the docker images and kept locally.

python ./simple_kube.py --create-docker <Docker_file_path>

7. Below command will create the docker images and push it to local registry which is enabled in microk8s.

python ./simplekube.py --create-push-docker <Docker_file_path>

8. show the status docker images.

python ./simple_kube.py --status-docker-image <imagename>

9. Remove the docker images.

python ./simple_kube.py --remove-docker-image <imagename>

10. List the docker images.

python ./simple_kube.py --docker-image list

11. It will create the docker images and push it to local registry and deploy the same in microk8s. Note: The above command need to run where the dockerfile exisits.

python ./simple_kube.py --create-push-deploy <docker_image_name>
