Registrar for Geth Bootnodes. bootnode-registrar
will resolve a DNS address record to a enode addresses that can then be consumed by geth --bootnodes=<enodes>
.
bootnode-registrar
is designed to be deployed on a Kubernetes cluster, but it should work anywhere. However, the following instructions make the presumption that you are on k8s:
-
Create a
bootnode
pod with 2 running containers:a. bootnode
``` bootnode --genkey=/etc/bootnode/node.key bootnode --nodekey=/etc/bootnode/node.key ```
b. http-server - webserver that returns the enode address
``` while [ 1 ]; do echo -e \"HTTP/1.1 200 OK\n\nenode://$(bootnode -writeaddress --nodekey=/etc/bootnode/node.key)@$(MY_IP):30301\" | nc -l -v -p 8080 || break; done; ```
-
Create a headless service for the
bootnode
pod(s) which will result in a DNS A record in the form ofmy-namespace.svc.cluster.local
.
$ git clone [email protected]:jpoon/bootnode-registrar.git
$ make
$ ./bootnode-registrar -service <dns-record-to-resolve>
-- or --
$ BOOTNODE_SERVIER=<dns-record-to-resolve> && ./bootnode-registrar
or skip all that and run the container
$ docker run jpoon/bootnode-registrar -p 9898:9898
Once running, a http server
$ curl localhost:9898
