Kubernetes

Create and manage K8S cluster using templates in an automated way ^.^

---

https://github.com/kubernetes/kops/blob/master/docs/cluster_spec.md

Requirements

---

• kops
• python3.6

Installation

---

from pypi

---

pip install kforce

from source

---

git clone https://github.com/ycliuhw/kforce.git
cd kforce

virtualenv -p $(which python3.6) venv
source venv/bin/activate
python setup.py install

Usage

---

create kops iam group, attach related policies, create user then add user to group:

AWS_PROFILE=[admin] make ensure_iam

create access key for kops user

AWS_PROFILE=[admin] make create_access_key

initialize templates dirs for a new cluster

AWS_PROFILE=[kops] kforce initialize --account-name=[aws-account1] --env=[s|p|u|m] --vpc-id=vpc-xxxx [--force=True]

build kops template

AWS_PROFILE=[kops] kforce build --account-name=[aws-account1] --env=[s|p|u|m] --vpc-id=vpc-xxxx

diff kops template

AWS_PROFILE=[kops] kforce diff --account-name=[aws-account1] --env=[s|p|u|m] --vpc-id=vpc-xxxx

apply kops template to create the cluster

AWS_PROFILE=[kops] kforce apply --account-name=[aws-account1] --env=[s|p|u|m] --vpc-id=vpc-xxxx
