# New Chaosknoten VM
Create a new VM on our Chaosknoten Server with DNS Name, Firewalling and network config.
This guide outlines the steps to take for creating a new VM (`myservice`) on Chaosknoten. It might also act as a useful reference for other environments however.
## 1. Reserve an IP Address
## IP and DNS
Decide on what kind of network configuration the VM needs.
In this guide we assume a public v6 and a non-public v4 in the v4-NAT network.
If you have special requirements, refer to TODO for more information on the different kinds of networks available on Chaosknoten.
Decide on what kind of network configuration the VM needs. In this guide we assume a public v6 and a non-public v4 in the v4-NAT network. If you have special requirements, refer to TODO for more information on the different kinds of networks available on Chaosknoten.
1. Allocate a fresh [v6 in NetBox in the v4-NAT v6-network](https://netbox.hamburg.ccc.de/ipam/prefixes/47/ip-addresses/).
- The _hostname_ should be the full FQDN, like: `myservice.hosts.hamburg.ccc.de`
## 2. Configure DNS
2. Add a new `AAAA` record pointing to the chosen v6 to the [`hamburg.ccc.de` zone](https://git.hamburg.ccc.de/CCCHH/ansible-infra/src/branch/main/resources/chaosknoten/auth-dns/zones/hamburg.ccc.de.zone).
It should look something like this:

4. Finally add the VM to NetBox

4. Finally assign the IP address created earlier in NetBox to the just created interface by going into the _Assignment_ section of the IP address configuration.
- Also check _Make this the primary IP for the device/VM_ while doing so.
## 5. Enroll the VM in ansible

- Guidance on setting up a web service can be found in the [Web Service](./web-service.md) guide.
Afterward you should also take care of setting up monitoring for the newly configured service, see: [Monitor a new service with Gatus](./monitor-a-new-service-with-gatus.md).
## Closing Up
This section is optional but if there's any way for the reader to verify their goal has been achieved, you should mention it here.
