I am going with this tutorial https://smith-mcf.medium.com/a-simple-solana-dapp-tutorial-6dedbdf65444

When I run localhost:8899 in chrome there is response "Used HTTP Method is not allowed. POST or OPTIONS is required"

I need to say im totally newbie about docker but the tutorial was requiring it.

It appears that you're using a mix of new and old unfortunately. The error that you're seeing:

Error: failed to get recent blockhash: Invalid params: unknown variant `finalized`, expected one of `max`, `recent`, `root`, `single`, `singleGossip`.

is because you're using a newer version of @solana/web3.js with a very old version of the network. The easiest solution is to downgrade to @solana/web3.js version 0.78.2 to keep following the tutorial.

Separately, there are a lot of newer tools for local development. If you're using a new version of the network and SDK, there's a binary called solana-test-validator (https://docs.solana.com/developing/test-validator) which is much easier than developing against Docker.
