Configuring the network on a target host¶
This example uses the following parameters to configure networking on a single target host. See Figure 3.2, “Target hosts for infrastructure, networking, and storage services” and Figure 3.3, “Target hosts for Compute service” for a visual representation of these parameters in the architecture.
VLANs:
- Host management: Untagged/Native
- Container management: 10
- Tunnels: 30
- Storage: 20
Networks:
- Host management: 10.240.0.0/22
- Container management: 172.29.236.0/22
- Tunnel: 172.29.240.0/22
- Storage: 172.29.244.0/22
Addresses:
- Host management: 10.240.0.11
- Host management gateway: 10.240.0.1
- DNS servers: 69.20.0.164 69.20.0.196
- Container management: 172.29.236.11
- Tunnel: 172.29.240.11
- Storage: 172.29.244.11
