Local moonbeam setup

[Neoblock8]

Hi,
Trying to setup a local moonbeam node.
Running command:
docker run --rm --name moonbeam_development --network host moonbeamfoundation/moonbeam:v0.34.1 --dev --rpc-external --sealing 3000 --rpc-port 9944
when i connected my server ip [ws://ip:9944] in "https://polkadot.js.org/" , it does not connect. Why?

Hi @Neoblock8 ,

It is hard to tell as we don't know the setup you are using, It is very likely because your docker is not opening the ports correctly.
You can try to do
docker run -p 9944:9944 --rm --name moonbeam_development --network host moonbeamfoundation/moonbeam:v0.34.1 --dev --rpc-external --sealing 3000 --rpc-port 9944

Can we modify chainid in dev mode?

[crystalin]

I don't think you can change it with the dev mode directly.

Your options are either:

1. modify the dev mode code to use a different chain_id and rebuild moonbeam
2. generate the genesis plain spec and modify the chain id and relaunch moonbeam with this local chain

Modified chain id in the below file and rebuild moonbeam. But the chainid remains same

the development network is using the moonbase runtime, so I think you change it there: https://github.com/moonbeam-foundation/moonbeam/blob/v0.34.1/node/service/src/chain_spec/moonbase.rs#L91

How to relaunch moonbeam with new chainid?

After doing a cargo build --release
you can run it with:
./target/release/moonbeam --dev --rpc-external --sealing 3000 --rpc-port 9944

Hi @crystalin,
The above command works. But can't connect local node in https://polkadot.js.org/apps

The error is Failed to construct 'WebSocket': An insecure WebSocket connection may not be initiated from a page loaded over HTTPS.

How to connect?

Hi @crystalin,

Where to modify the currency name?

[RomarQ]

The "currency" symbol can be modified by changing the tokenSymbol property in the chain spec.
