How to run taliscale (E2E) Tests
Tailscale requires three steps before running the test:
1 - Log into tailscale or create an account "https://login.tailscale.com/"
2 - In the Access controls section, add the cluster routes in the autoApprovers section. For example:
"autoApprovers": {
"routes": {
"10.42.0.0/16": ["testing@xyz.com"],
"2001:cafe:42:0::/56": ["testing@xyz.com"],
},
},
3 - In Settings > Keys, generate an auth key which is Reusable and Ephemeral. That key should be the value of a new env variable E2E_TAILSCALE_KEY
Typical problems
The cluster does not start correctly
Please verify that the tailscale key was correctly passed to the config. To verify this, check the config in the server/agent in the file /etc/rancher/k3s/config.yaml
The verification on the routing fails
Please verify that you filled the autoApprovers section and that the config applies to your key. If you access the tailscale UI and see that the machine has "Subnets" that require manual approval, the test will not work
