nm-configurator (or nmc) is a CLI tool which makes it easy to generate and apply NetworkManager configurations.
## How to install it?
### Download from release
Each release is published with nmc already built for `amd64` and `arm64` Linux systems:
```shell
$ curl -o nmc -L https://github.com/suse-edge/nm-configurator/releases/latest/download/nmc-linux-$(uname -m)
$ chmod +x nmc
```
### Build from source
```shell
$ git clone https://github.com/suse-edge/nm-configurator.git
$ cd nm-configurator
$ cargo build --release # only supports Linux based systems
```
## How to run it?
nmc depends on having the desired network state for all known nodes beforehand.
[NetworkManager](https://documentation.suse.com/sle-micro/5.5/html/SLE-Micro-all/cha-nm-configuration.html)
is using connection profiles defined as files stored under `/etc/NetworkManager/system-connections`.
In order to generate these config (*.nmconnection) files, nmc uses the
[nmstate](https://github.com/nmstate/nmstate) library and requires a configuration directory as an input.
This directory must contain the desired network state in one of the following file formats:
1. A single or multiple `<hostname>.yaml` files containing the different configurations per host.
This method requires specifying the MAC addresses of all Ethernet interfaces for each host
in order to properly identify the relevant configurations when applying those.
2. A single `_all.yaml` file containing the configurations to be applied to all hosts.
This method does not depend on MAC address matching.
nmc is then able to apply the generated configurations by identifying and storing the relevant NetworkManager settings for a given host.
Typically used with [Combustion](https://documentation.suse.com/sle-micro/5.5/single-html/SLE-Micro-deployment/#cha-images-combustion)
in order to bootstrap multiple nodes using the same provisioning artefact instead of depending on different custom images per machine.
### Per node configurations
#### Prepare desired states
```shell
mkdir -p desired-states
cat <<- EOF > desired-states/node1.yaml
interfaces:
- name: eth0
type: ethernet
state: up
mac-address: FE:C4:05:42:8B:AA
ipv4:
address:
- ip: 192.168.122.250
prefix-length: 24
enabled: true
ipv6:
address:
- ip: 2001:db8::1:1
prefix-length: 64
enabled: true
EOF
cat <<- EOF > desired-states/node2.yaml
interfaces:
- name: eth1
type: ethernet
state: up
mac-address: FE:C4:05:42:8B:AB
ipv4:
address:
- ip: 192.168.123.250
prefix-length: 24
enabled: true
ipv6:
enabled: false
EOF
cat <<- EOF > desired-states/node3.yaml
interfaces:
- name: eth4
type: ethernet
state: up
mac-address: FE:C4:05:42:8B:AC
ipv4:
address:
- ip: 192.168.124.250
prefix-length: 24
enabled: true
ipv6:
enabled: false
EOF
```
Please refer to the official nmstate docs for more extensive [examples](https://nmstate.io/examples.html).
#### Generate configurations
```shell
$ ./nmc generate --config-dir desired-states --output-dir network-config
[2024-11-12T09:05:57Z INFO nmc::generate_conf] Generating config from "desired-states/node1.yaml"...
[2024-11-12T09:05:59Z INFO nmc::generate_conf] Generating config from "desired-states/node2.yaml"...
[2024-11-12T09:05:59Z INFO nmc::generate_conf] Generating config from "desired-states/node3.yaml"...
[2024-11-12T09:05:59Z INFO nmc] Successfully generated and stored network config
$ find network-config | sort
network-config
network-config/host_config.yaml
network-config/node1
network-config/node1/eth0.nmconnection
network-config/node2
network-config/node2/eth1.nmconnection
network-config/node3
network-config/node3/eth4.nmconnection
```
There are separate directories for each host (identified by their input <i>hostname</i>.yaml).
Each of these contains the configuration files for the desired network interfaces (e.g. `eth0`).
The `host_config.yaml` file on the root level maps the hosts to all of their preconfigured interfaces.
This is necessary in order for nmc to identify which host it is running on when applying the network configurations later.
```yaml
- hostname: node1
interfaces:
- logical_name: eth0
connection_ids:
- eth0
mac_address: FE:C4:05:42:8B:AA
interface_type: ethernet
- hostname: node2
interfaces:
- logical_name: eth1
connection_ids:
- eth1
mac_address: FE:C4:05:42:8B:AB
interface_type: ethernet
- hostname: node3
interfaces:
- logical_name: eth4
connection_ids:
- eth4
mac_address: FE:C4:05:42:8B:AC
interface_type: ethernet
```
#### Apply configurations
Simply copy the directory containing the results from `nmc generate` (`network-config` in the example above) to the target host.
```shell
$ ./nmc apply --config-dir network-config
[2024-11-12T09:10:10Z INFO nmc::apply_conf] Identified host: node2
[2024-11-12T09:10:10Z INFO nmc::apply_conf] Set hostname: node2
[2024-11-12T09:10:11Z INFO nmc::apply_conf] Processing interface 'eth1'...
[2024-11-12T09:10:11Z INFO nmc::apply_conf] Processing connection 'eth1'...
[2024-11-12T09:10:11Z INFO nmc::apply_conf] Using interface name 'enp0s1' instead of the preconfigured 'eth1'
[2024-11-12T09:10:11Z INFO nmc] Successfully applied config
$ ls /etc/NetworkManager/system-connections
enp0s1.nmconnection
```
**NOTE:** Interface names during the installation of nodes might differ from the preconfigured logical ones.
This is expected and nmc will rely on the MAC addresses and use the actual names for the NetworkManager
configurations instead e.g. settings for interface with a predefined logical name `eth1` but actually named
`enp0s1` on the target node will automatically be adjusted and stored to `/etc/NetworkManager/enp0s1.nmconnection`.
### Unified configurations
There are occasions where relying on known MAC addresses is not an option.
In these cases we can opt for the so-called _unified_ configurations which allows us
to specify settings in an `_all.yaml` file which will then be applied across all provisioned nodes.
```shell
mkdir -p desired-states
cat <<- EOF > desired-states/_all.yaml
interfaces:
- name: eth0
type: ethernet
state: up
ipv4:
dhcp: true
enabled: true
ipv6:
enabled: false
- name: eth1
type: ethernet
state: up
ipv4:
address:
- ip: 10.0.0.1
prefix-length: 24
enabled: true
dhcp: false
ipv6:
enabled: false
EOF
```
#### Generate configurations:
```shell
$ ./nmc generate --config-dir desired-states --output-dir network-config
[2024-05-27T07:23:20Z INFO nmc::generate_conf] Generating config from "desired-states/_all.yaml"...
[2024-05-27T07:23:20Z INFO nmc] Successfully generated and stored network config
$ find network-config | sort
network-config
network-config/_all
network-config/_all/eth0.nmconnection
network-config/_all/eth1.nmconnection
```
**NOTE:** The `host_config.yaml` file will not be present since host mapping is not necessary.
#### Apply configurations:
```shell
$ ./nmc apply --config-dir network-config
[2024-05-27T07:24:03Z INFO nmc::apply_conf] Applying unified config...
[2024-05-27T07:24:03Z INFO nmc::apply_conf] Copying file... "network-config/_all/eth0.nmconnection"

[2024-05-27T07:24:03Z INFO nmc] Successfully applied config
$ ls /etc/NetworkManager/system-connections

```
