Issue/Introduction

We are trying to configuring container (docker) gateway version 10.0 using docker hub image of  api gateway.

After a few restarts the cluster_info table is filled with failed container id . 

Which are also showing up the policymanager dashboard.

How is this cleaned up ?

Environment

Release : 10.0

Component : API GATEWAY

Resolution

There is a process in the gateway which cleans up this table but the default is that the entry must be inactive for 90 days.

You can set the following property in the system.properties file to change this

com.l7tech.server.clusterStaleNodeCleanupTimeoutSeconds=86400s

which means  clean up the entry after 1 day inactivity

To set this in docker you have to add it to the yaml file 

https://techdocs.broadcom.com/us/en/ca-enterprise-software/layer7-api-management/api-gateway/congw-10-1/reference/gateway-system-properties.html

The other option is to clear the entries manual from the cluster_info table in the mysql database when needed.
