Shards failed in Network screen

Does this thread help?

The shard cannot be allocated to the same node on which a copy of the shard already exists

This is a replica, but you only have one node, so of course no replicas can be allocated. You should set number_of_replicas: 0 on all your indices.

I think you have only one node which is why it's yellow to start with. If you only want one node I think the advice on there should fix you up here.
