Replication Between TYK Servers

[Olu]

Hi @saloni512,

There is no inbuilt configuration to sync the API definitions and configuration files. You can sync them by using the same kind of configuration described in the first point as shown below

• Sharing /opt/tyk-gateway (anything else?) using a persistent volume (e.g. AWS EFS/EBS ).

If you are using Kubernetes, then @chris.f shares how to do this using environment variables and config map mounts.

@chris.f

Yes you can just increase the number of replicas, however just to be clear, each of the gateways needs to have similar/same configurations, which you can set using environment variables in the k8s definition rather than using the gateway config alone. Furthermore the policies and api definitions are loaded from a local files to the gateway process (so inside the container), however of course you can create a configmaps for these and mount it the same way on every gateway pod or use another consistent mechanism that scales with your deploymentset. This way all the gateways have the same config (via local file or preferably, environment variables) and the same api and policy definitions to load, and when sharing the same redis instance they will use the same keystore and act like a cluster, by which I mean things like load balancing and rate limiting can be enforced across the group of gateways rather than individually.

Hope this helps.
