trying Jacek suggestion in #591, I added nat setting to
nimbus-eth1 hive shell script. visible difference after adding
this flag is the nat library not complaining about
"the gateway does not support nat-pmp" anymore.
but the slow startup time described in #591 is yet to be measured
again, although I already see improvement when executing
ethereum/consensus category in hive.
- Explain some of the prerequisites in more detail (Go version).
- Practical issues around Go version and Docker configuration to make it work.
- Make the first example be one that works with nimbus-eth1.
(Instead of giving an obscure error message that looks like the user's Docker
setup is broken).
- Rename to `README.md` per convention.
