description: "Creating Talos Kubernetes cluster using Docker."
|
|
---
|
|
|
|
In this guide we will create a Kubernetes cluster in Docker, using a containerized version of Talos.
|
|
|
|
Running Talos in Docker is intended to be used in CI pipelines, and local testing when you need a quick and easy cluster.
|
|
Furthermore, if you are running Talos in production, it provides an excellent way for developers to develop against the same version of Talos.
|
|
|
|
## Requirements
|
|
|
|
The follow are requirements for running Talos in Docker:
|
|
|
|
- Docker 18.03 or greater
|
|
- a recent version of [`talosctl`](https://github.com/talos-systems/talos/releases)
|
|
|
|
## Caveats
|
|
|
|
Due to the fact that Talos runs in a container, certain APIs are not available when running in Docker.
|
|
For example `upgrade`, `reset`, and APIs like these don't apply in container mode.
|
|
|
|
## Create the Cluster
|
|
|
|
Creating a local cluster is as simple as:
|
|
|
|
```bash
|
|
talosctl cluster create --wait
|
|
```
|
|
|
|
Once the above finishes successfully, your talosconfig(`~/.talos/config`) will be configured to point to the new cluster.
|
|
|
|
If you are running on MacOS, an additional command is required:
|
|
|
|
```bash
|
|
talosctl config --endpoints 127.0.0.1
|
|
```
|
|
|
|
> Note: Startup times can take up to a minute before the cluster is available.
|
|
|
|
## Retrieve and Configure the `kubeconfig`
|
|
|
|
```bash
|
|
talosctl kubeconfig .
|
|
kubectl --kubeconfig kubeconfig config set-cluster talos-default --server https://127.0.0.1:6443
|
|
```
|
|
|
|
## Using the Cluster
|
|
|
|
Once the cluster is available, you can make use of `talosctl` and `kubectl` to interact with the cluster.
|
|
For example, to view current running containers, run `talosctl containers` for a list of containers in the `system` namespace, or `talosctl containers -k` for the `k8s.io` namespace.
|
|
To view the logs of a container, use `talosctl logs <container>` or `talosctl logs -k <container>`.
|
|
|
|
## Cleaning Up
|
|
|
|
To cleanup, run:
|
|
|
|
```bash
|
|
talosctl cluster destroy
|
|
```
