feat: implement collector and analyser for network namespace connecti…
…vity
checks if two network namespaces can talk to each other on udp and tcp.
its usage is as follows:
```yaml
apiVersion: troubleshoot.sh/v1beta2
kind: SupportBundle
metadata:
name: test
spec:
hostCollectors:
- networkNamespaceConnectivity:
collectorName: check-network-connectivity
fromCIDR: 10.0.0.0/24
toCIDR: 10.0.1.0/24
hostAnalyzers:
- networkNamespaceConnectivity:
collectorName: check-network-connectivity
outcomes:
- pass:
message: "Communication between 10.0.0.0/24 and 10.0.1.0/24 is working"
- fail:
message: "Communication between 10.0.0.0/24 and 10.0.1.0/24 isn't working"
```
if this fails then you may need to enable `forwarding` with:
```bash
sysctl -w net.ipv4.ip_forward=1
```
if it still fails then you may need to configure firewalld to allow the
traffic or simply disable it for sake of testing.- Loading branch information
