Document a fast run of 1 single node for development (devnet)

[Muhammad-Altabba]

Is your feature request related to a problem? Please describe.
Need to simply run a single node for development. But could not find a documentation for that. There is only a documentation for runing a node on mainnet or testnet, or to run a private network using Kurtosis. But as a developer I do not need to have 3 nodes and setup and configure an additional application (Kurtosis) just to be able to try Nethermind. Or is it just not possible with the current configuration possibility to run only one stand alone node for development?

Describe the solution you'd like
To simply support an easy way to run a standalone devnet node and document this. For example, in geth, the developers just pass --dev flag.

Describe alternatives you've considered
Check please: https://geth.ethereum.org/docs/developers/dapp-developer/dev-mode

Thanks,

[MarekM25]

Thanks for reporting, @Muhammad-Altabba.

The equivalence of dev mode in Geth in Nethermind is spaceneth. To run this, you can specify the config:
./nethermind -c spaceneth

However, thanks for your feedback about the docs. Indeed, this is missing.

@rubo, could you explore this topic whenever you have time?

The equivalence of dev mode in Geth in Nethermind is spaceneth. To run this, you can specify the config: ./nethermind -c spaceneth

Many thanks,
I tried nethermind -c spaceneth but that failed short with the following log:

So, I tryed doing this with docker (docker is well configured on my machine and I use it for many other stuff).
And, I run docker run -v /nethermind/ipc:/ipc nethermind/nethermind -c spaceneth. Which gave:

I followed https://docs.nethermind.io/get-started/installing-nethermind/#standalone-downloads and https://docs.nethermind.io/get-started/installing-nethermind/#docker-container to install Nethermind local and using docker.
I am using Linux Mint v21.3. And Docker version 24.0.7, build 24.0.7-0ubuntu2~22.04.1.
