nerdctl network create supports --aux-address
Introduced 2026-09-20 · score 0.94
HOW TO USE IT
When creating a network with reserved auxiliary addresses, run `nerdctl network create` with one or more `--aux-address name=IP` pairs. Each IP is reserved and never assigned to a container; each pair is matched to the subnet containing its IP.
nerdctl network create --subnet=<CIDR> --aux-address=<name>=<IP> <NETWORK>WHY THIS HELPS
Create a network with auxiliary address configuration.
REQUIREMENTS AND LIMITATIONS
- Version: v2.4.0
- NETWORK (required): Name of the network to create; the command syntax requires this argument.
- --aux-address: Repeatable `name=IP` pair for an auxiliary IPv4 or IPv6 address. Each IP is reserved from container assignment and matched to the subnet containing it.
- --subnet: Subnet in CIDR format representing a network segment.
