+This is useful to do so you can test changes with real alertmanager data containing slack channel information. 
+
+Create a port forward pod:
+
+```bash
+kubectl \
+  -n hmpps-portfolio-management-dev \
+  run port-forward-pod-alertmanager \
+  --image=ministryofjustice/port-forward \
+  --port=6379 \
+  --env="REMOTE_HOST=[Alertmanager host]" \
+  --env="LOCAL_PORT=6547" \
+  --env="REMOTE_PORT=8080"
+```
+
+Use kubectl to port-forward to it:
+
+```bash
+kubectl \
+  -n hmpps-portfolio-management-dev \
+  port-forward \
+  port-forward-pod-alertmanager 6574:6574
