3.10. Managing Virtual Networks¶
3.10.1. vinfra service compute network create¶
Create a compute network:
usage: vinfra service compute network create [--dhcp | --no-dhcp]
[--dns-nameserver <dns-nameserver>]
[--allocation-pool <allocation-pool>]
[--gateway <gateway> | --no-gateway]
[--ip-version <ip-version>]
[--physical-network <physical-network>]
[--cidr <cidr>] <network-name>
--dhcp- Enable DHCP.
--no-dhcp- Disable DHCP.
--dns-nameserver <dns-nameserver>- DNS server IP address. This option can be used multiple times.
--allocation-pool <allocation-pool>- Allocation pool to create inside the network in the format:
ip_addr_start-ip_addr_end. This option can be used multiple times. --gateway <gateway>- Gateway IP address
--no-gateway- Do not configure a gateway for this network.
--ip-version <ip-version>- Network IP version
--physical-network <physical-network>- A physical network to link to a public network
--cidr <cidr>- Subnet range in CIDR notation
<network-name>- Network name
Example:
# vinfra service compute network create myprivnet --type vxlan \
--cidr 192.128.128.0/24 --gateway 192.128.128.1
+------------------+--------------------------------------+
| Field | Value |
+------------------+--------------------------------------+
| id | 3848fb5d-bc98-4320-acd0-cde2df7c5bdd |
| name | myprivnet |
| physical_network | |
| project_id | 72a5db3a033c403a86756021e601ef34 |
| subnet | allocation_pools: |
| | - end: 192.128.128.254 |
| | start: 192.128.128.2 |
| | cidr: 192.128.128.0/24 |
| | dns_nameservers: [] |
| | enable_dhcp: true |
| | gateway_ip: 192.128.128.1 |
| | ip_version: 4 |
| type | vxlan |
+------------------+--------------------------------------+
This command creates a private network myprivnet with the specific CIDR and gateway.
3.10.2. vinfra service compute network list¶
List compute networks:
usage: vinfra service compute network list
Example:
# vinfra service compute network list -c id -c name -c cidr -c type -c allocation_pools
+----------------+-----------+-------+------------------+------------------------+
| id | name | type | cidr | allocation_pools |
+----------------+-----------+-------+------------------+------------------------+
| 1bf2c9da-<...> | private | vxlan | 192.168.128.0/24 | - end: 192.168.128.254 |
| | | | | start: 192.168.128.2 |
| 3848fb5d-<...> | myprivnet | vxlan | 192.128.128.0/24 | - end: 192.128.128.254 |
| | | | | start: 192.128.128.2 |
| 417606ac-<...> | public | flat | 10.94.0.0/16 | - end: 10.94.129.79 |
| | | | | start: 10.94.129.64 |
+----------------+-----------+-------+------------------+------------------------+
This command lists networks used in the compute cluster. (The output is abridged to fit on page.)
3.10.3. vinfra service compute network show¶
Display compute network details:
usage: vinfra service compute network show <network>
<network>- Network ID or name
Example:
# vinfra service compute network show 417606ac-1dbe-426a-844d-e047831ddce9
+------------------+--------------------------------------+
| Field | Value |
+------------------+--------------------------------------+
| allocation_pools | |
| cidr | |
| dns_nameservers | |
| enable_dhcp | |
| gateway_ip | |
| id | 417606ac-1dbe-426a-844d-e047831ddce9 |
| ip_version | |
| name | public |
| physical_network | Public |
| project_id | 72a5db3a033c403a86756021e601ef34 |
| type | flat |
+------------------+--------------------------------------+
This command shows the details of the network with the ID 417606ac-1dbe-426a-844d-e047831ddce9.
3.10.4. vinfra service compute network set¶
Modify compute network parameters:
usage: vinfra service compute network set [--dhcp | --no-dhcp]
[--dns-nameserver <dns-nameserver>]
[--allocation-pool <allocation-pool>]
[--gateway <gateway> | --no-gateway]
[--name <name>] <network>
--dhcp- Enable DHCP.
--no-dhcp- Disable DHCP.
--dns-nameserver <dns-nameserver>- DNS server IP address. This option can be used multiple times.
--allocation-pool <allocation-pool>- Allocation pool to create inside the network in the format:
ip_addr_start-ip_addr_end. This option can be used multiple times. --gateway <gateway>- Gateway IP address
--no-gateway- Do not configure a gateway for this network.
--name <name>- A new name for the network
<network>- Network ID or name
Example:
# vinfra service compute network set myprivnet --no-dhcp
+------------------+--------------------------------------+
| Field | Value |
+------------------+--------------------------------------+
| id | 3848fb5d-bc98-4320-acd0-cde2df7c5bdd |

| | ip_version: 4 |
| type | vxlan |
+------------------+--------------------------------------+
This command disables DHCP for the private network myprivnet.
3.10.5. vinfra service compute network delete¶
Delete a compute network:
usage: vinfra service compute network delete <network>
<network>- Network ID or name
Example:
# vinfra service compute network delete myprivnet
Operation successful
This command deletes the private network myprivnet.
