# Tailscale in Docker without elevated privileges
|
|
|
|
See associated blog post: <https://asselin.engineer/tailscale-docker>
|
|
|
|
**Set the TAILSCALE_AUTH_KEY with your own ephemeral auth key**: <https://login.tailscale.com/admin/settings/keys>
|
|
|
|
## docker-compose
|
|
|
|
The examples detailed below are in the docker-compose folder.
|
|
|
|
By default, no state is saved. The nodes are removed from the network when the tailscale container is terminated. This means the ip address is never the same.
|
|
The `stateful-example` does save the tailscale node state to a docker volume.
|
|
|
|
Requirements:
|
|
- [docker-compose](https://docs.docker.com/compose/install/)
|
|
|
|
Usage:
|
|
````bash
|
|
export TAILSCALE_AUTH_KEY="your-key"
|
|
# set which project is used
|
|
export PROJECT_DIRECTORY="docker-compose/simple-example"
|
|
# Sart with rebuild if necessary:
|
|
docker-compose --project-directory=${PROJECT_DIRECTORY} up -d --build
|
|
# Show logs and tail (follow):
|
|
docker-compose --project-directory=${PROJECT_DIRECTORY} logs --follow
|
|
# Stop:
|
|
docker-compose --project-directory=${PROJECT_DIRECTORY} down
|
|
````
|
|
|
|
### simple-example
|
|
|
|
As explained in the blog post, uses a docker-compose service to add the container in the VPN.
|
|
|
|
### complex-example
|
|
|
|
Not complex but more complex than the simple-example.
|
|
A nginx layer is added. It manages two services in independent containers at urls `/service-one` and `/service-two`.
|
|
|
|
### stateful-example
|
|
|
|
Same as simple-example but uses a volume to save state. The goal is to be able to reuse the same tailscale hostname _and ip address_.
|
|
Useful in situations where the tailscale magic DNS cannot be used.
|
|
|
|
## K8S
|
|
|
|
Same as the simple-example but on kubernetes.
|
|
|
|
Requirements:
|
|
|
|
- [Kind](https://kind.sigs.k8s.io/docs/user/quick-start/#installing-with-a-package-manager)
|
|
- [Kubectl](https://kubernetes.io/docs/tasks/tools/)
|
|
|
|
Usage:
|
|
````bash
|
|
# Create cluster
|
|
kind create cluster --name tailscale
|
|
kubectl get nodes
|
|
# Deploy tailscale and demo webpage:
|
|
kubectl apply -f k8s/simple-example/deployment.yaml
|
|
# Delete cluster:
|
|
kind delete cluster --name tailscale
|
|
