21:39:01 GMT Hey, when redis runs with a master and multiple slaves, is the master only able to write? 21:39:05 GMT How does this actually work? 21:53:56 GMT is there a reliable pattern which can execute an action when a item expires? It looks like pubsubs are not a great choice when you want reliablity. 23:04:02 GMT <_ew_> It works after add --net=host when run redis cluster in docker? But why? Why cannot use -p to expose the ports?
