One of the KubeInit’s pillars is to define a common framework to deploy multiple Kubernetes distributions, once you finish the deployment you should be able to use the specific distro tooling to mange the lifecycle of your deployment (or multiple deployments).
Using KubeInit you should be able to reuse a common set of third party services, and infrastructure deployment assets with any already integrated distro.
The current distributions of Kubernetes that should be deployable are:
- Origin Kubernetes Distribution
- Rancher Kubernetes Distribution
- Canonical Distribution of Kubernetes
Disclaimer: This does not fully work, yet xD… Multiple scenarios might be broken, the DNS might not work properly and the HAProxy service might be failing also, this is the reason why is not documented in the official docs. Any contribution is and always be welcomed. Yet, the deployment should finish successfully.
The roles and playbooks structure
Every supported distro has a role folder called like
kubeinit_<distro>, this means,
Then, there is a specific playbook for each distro named using their distribution
This means that the workflow to deploy any distro must be the same for every one of them.
Choose the Kubernetes distribution you will use:
- Origin Kubernetes Distribution: okd
- Kubernetes: k8s
- Rancher Kubernetes Distribution: rke
- Canonical Distribution of Kubernetes : cdk
# Choose the distro # distro=k8s # distro=rke # distro=cdk distro=okd # Run the deployment command git clone https://github.com/kubeinit/kubeinit.git cd kubeinit ansible-playbook \ --user root \ -v -i ./hosts/$distro/inventory \ --become \ --become-user root \ ./playbooks/$distro.yml
Being able to deploy multiple Kubernetes distributions in an easy, quick, reproducible, and using the same interface allow users to test and evaluate them to see which one (or many) fits better their use cases.
