Please note that by including that in your PodSpec will allow some pods to run in that node, but it won’t ensure that all pods only use the tainted nodes, if you want to achieve that then you will need to label the nodes and use the affinity selectors.
In order to enable connectivity between VPCs, you must initiate the peering connection from one VPC, and then accept the request on the other VPC. Once the connectivity has been accepted and established, a new route needs to be added to each route table, in each VPC, for the peering connection. This is done by adding a route with the other VPC’s CIDR range as the Destination, and then thepcx ID of the peering connection as the Target. At this point, connectivity is established between the VPCs, and traffic is routeable between the resources in both.
