Configuration

Initial Setup in Bionic

When you install Bionic or use a cloud image of Bionic a file will appear in /etc/netplan depending on the renderer in use. Here is a breakdown of the various types:

Do note that configuration files can exist in three different locations with the precidence from most important to least as follows:

• /run/netplan/*.yaml
• /etc/netplan/*.yaml
• /lib/netplan/*.yaml

Alphabetically later files, no matter what directory they are in, will amend keys if the key does not already exist and override previous keys if they do.

Examples

The best method for demonstrating what netplan can do is by showing some examples. Keep in mind that these are very simple examples that do not demonstrate complex situations that netplan can handle.

Static and DHCP Addressing

The following configures four devices:

• enp3s0 setup with IPv4 DHCP
• enp4s0 setup with IPv4 static with custom MTU
• IPv6 static tied to a specific MAC address
• IPv4 and IPv6 DHCP with jumbo frames tied to a specific MAC address

ethernets:
    enp3s0:
        dhcp4: true
    enp4s0:
        addresses:
            - 192.168.0.10/24
        gateway4: 192.168.0.1
        mtu: 1480
        nameservers:
            addresses:
                - 8.8.8.8
                - 9.9.9.9
    net1:
        addresses:
            - fe80::a00:10a/120
        gateway6: fe80::a00:101
        match:
            macaddress: 52:54:00:12:34:06
    net2:
        dhcp4: true
        dhcp6: true
        match:
            macaddress: 52:54:00:12:34:07
        mtu: 9000
