KB - Redis connectivity after successful service upgrade.

Problem

After upgrading the Redis services, the services are restarted and the pods addresses change. To reflect this change in pods that require Redis a manual pod restart is required. This is pertinent to any upgrades related to system-redis and redis in the upgrade panel.

🌱 Solution

Please perform the following steps exactly as described in the sequence as described below:

Requirements:

kubectl configured and available for cli interaction with your SIEMonster Kubernetes cluster.

Actions after upgrading System-redis in the [GLOBAL] section of the update panel:

Run the following command, note that the <global_ns> should be replaced with the namespace that corresponds with your full domain e.g. in the case of domain example.siemonster.io the command would be kubectl -n example delete po $(kubectl -n example get pod | grep siemonster- | awk '{print $1}')
BASH
```
kubectl -n <global_ns> delete pod $(kubectl -n <global_ns> get pod | grep siemonster- | awk '{print $1}')
```

Actions after upgrading Redis in the tenant section of the update panel:

After you update, wait for 5 minutes then run the following command with <tenant_ns> replaced with the tenant name which you can see at the top right of the web interface e.g. kubectl -n tenant1 delete po $(kubectl -n tenant1 get pod | grep 'webreporting\|elastalert\|attack-map\|sclla-controller\|exporter' | awk '{print $1}')

BASH

kubectl -n <tenant_ns> delete pod $(kubectl -n <tenant_ns> get pod | grep 'webreporting\|elastalert\|attack-map\|scylla-controller\|exporter' | awk '{print $1}')

NOTE: Step 2 will have to be repeated for each tenant after upgrading system-redis
