MAAS-configured network services reduce friction by eliminating setup challenges.
Manage DHCP
Enable MAAS DHCP
UI:
Subnets > (Select VLAN) > Configure DHCP (Fill fields) > Configure DHCP
CLI:
maas $PROFILE vlan update $FABRIC_ID $VLAN_ID dhcp_on=True primary_rack=$PRIMARY_RACK
Note: Make sure you have the correct $VLAN_ID (vid in the help output).
Enable DHCP for HA
CLI
maas $PROFILE vlan update $FABRIC_ID $VLAN_ID dhcp_on=True primary_rack=$PRIMARY_RACK secondary_rack=$SECONDARY_RACK
Note: Make sure you have the correct $VLAN_ID (vid in the help output).
Set up a DHCP relay
UI
Subnets > (Select VLAN) > Configure DHCP > Relay to another VLAN > (Select VLAN) > Configure DHCP
CLI:
maas $PROFILE vlan update $FABRIC_ID $VLAN_VID_SRC relay_vlan=$VLAN_ID_TARGET
Manage DHCP snippets
Create snippets
UI
Settings > DHCP snippets > Add snippet > (Fill fields) > Save snippet
CLI (global snippet)
maas $PROFILE dhcpsnippets create name=$DHCP_SNIPPET_NAME value=$DHCP_CONFIG description=$DESCRIPTION global_snippet=true
CLI (subnet snippet)
maas $PROFILE dhcpsnippets create name=$DHCP_SNIPPET_NAME value=$DHCP_CONFIG description=$DESCRIPTION subnet=$SUBNET_ID
CLI (node snippet)
maas $PROFILE dhcpsnippets create name=$DHCP_SNIPPET_NAME value=$DHCP_CONFIG description=$DESCRIPTION node=$NODE_ID
List snippets
UI
Settings > DHCP snippets
CLI
maas $PROFILE dhcpsnippets read
Update a snippet
UI
Settings > DHCP snippets > Actions > Pencil icon (edit) > (Edit snippet) > Save snippet
maas $PROFILE dhcpsnippet update $DHCP_SNIPPET_ID enabled=false
Delete a snippet
UI
Settings > DHCP snippets > Actions > Trash can icon (delete) > Delete
CLI
maas $PROFILE dhcpsnippet delete $DHCP_SNIPPET_ID
Manage NTP
Use external NTP
UI:
Settings > Network > NTP > (Fill in NTP address) > External Only > Save
CLI:
maas $PROFILE maas set-config name=ntp_servers value=$NTP_IP_ADDRESS
maas $PROFILE maas set-config name=ntp_external_only value=true
Manage DNS
Use the built-in, MAAS-configured DNS server to manage domains more efficiently.
Create a DNS resource
Prerequisites
- You have a running MAAS installation.
- You have administrative access to MAAS.
- You have at least one domain set up in MAAS.
Identify your domain
Each DNS resource needs a domain. You can find available domains in MAAS by running:
maas admin domains read
Look for the id or name of the domain you want to use.
Choose a hostname
Decide on the hostname for the new DNS record. You can either:
- Provide a fully qualified domain name (FQDN), e.g.,
webserver.example.com - OR specify the
name(hostname only) and thedomainseparately.
Assign an IP address (optional)
If you want to create an A (IPv4) or AAAA (IPv6) record, you need an IP address:
maas admin ipaddresses read
This lists available IP addresses in MAAS.
Create the DNS resource
Run the following command:
maas admin dnsresources create name=webserver domain=example.com ip_addresses=192.168.1.100
Alternatively, using an FQDN:
maas admin dnsresources create fqdn=webserver.example.com ip_addresses=192.168.1.100
This creates an A record for webserver.example.com pointing to 192.168.1.100.
Verify the DNS resource
List all DNS resources:
maas admin dnsresources read
Ensure your new entry appears in the output.
Set a DNS server
UI
Settings > DNS > (Fill fields) > Save
CLI
maas $PROFILE subnet update $SUBNET_CIDR dns_servers=$MY_DNS_SERVER
Set a DNS forwarder
CLI
maas $PROFILE maas set-config name=upstream_dns value=$MY_UPSTREAM_DNS
