[Infra] Create local testnet
We should have a docker-compose that allows us to have a local testnet, with an already working full node (e.g. prysm+geth) and a testing full node (e.g. lambda ethereum consensus + reth), with an empty blockchain. This would allow us to quickly test gossiping, propagation of blocks, and others in a controlled manner, and with low resources (i.e. we won't need to save the 2TB full mainnet blockchain locally). While this is not a full-proof method, it allows us to iterate quickly and is perfectly valid to test integrations.
We can modify these scripts from lighthouse to run our nodes instead. Some things to consider:
- we'll need to add some new flags to our implementation (mainly set port in P2P/HTTP and import initial data from some dir)
- they require installing some external tools (lighthouse, geth, and GNU grep+sed when on mac)
Expanding on this, we'd need to add the following functionality:
- import a genesis state (which corresponds to phase0) and update it to the latest spec
- flags to set all ports (P2P, discovery, Beacon API)
- load a custom config from a yaml
@Arkenan, If I understand this issues correctly, Kurtosis is used today to accomplish this. This issue doesn't refer to smoketests but manual test right? This is tracked in #812 as:
- Add scripts and instructions for setting up/tearing down a local testnet
Which have been added as make task alongside documentation in #1197
