| # Use case: Boot instances to a provider flat network. Upstream physcial router is gateway. | |
| # Host net info is manually assigned (through cloud-init). | |
| # Current neutron model associated an address from this network even if dhcp is set to false. | |
| # This causes confusion to the cloud user/admin becase the cloud-init manual address differs | |
| # from address in nova list output. | |

| Use Case: | |
| Have docker-spotter look at events from the docker daemon to issue a pipework command. The events of interest are create/stop/restart/destroy container xyz. The pipework command creates a veth on a linux bridge named kbr-ex and attaches the other side of the veth (i.e. eth1) to the container. Since the container's eth1 interface is being used to bridge traffic, it does not use an IP address and therefore 0/0 is provided in the pipework command: | |
| # /usr/bin/docker-spotter -e nova-network:start,restart:pipework:kbr-ex:{{.ID}}:0/0 -e nova-network:stop:echo:gone | |
| This solution works very well when using a known name for a container. | |
| The Challenge: | |
| Kubernetes is being used to manage Docker containers. Kubernetes appends a hash to the Docker container name. Therefore, trying to use docker-spotter to match a specific name is not possible. |
