Scenario:
|
|
1. Install k8s.
|
|
2. Run netchecker-server service
|
|
3. Check that netchecker-server returns 400: 'There are no pods'
|
|
4. Run netchecker-agent daemon set
|
|
5. Get network verification status. Check status is 'OK'
|
|
6. Randomly choose some k8s node, login to it via SSH, add blocking
|
|
rule to the calico policy. Restart network checker server
|
|
7. Get network verification status, Check status is 'FAIL'
|
|
8. Recover calico profile state on the node
|
|
9. Get network verification status. Check status is 'OK'
