# Running a node (Lighthouse/Geth) on Dencun devnet-12
Docker Compose setup for running a Lighthouse/Geth node on Dencun devnet-12. Builds docker images from Dencun devnet-12 branches of Lighthouse and Geth.
## Run with Docker
```
docker-compose up --build
```
If you've previously used this repo to run earlier devnets, you'll need to remove old containers and volumes with the below command first:
```
docker-compose rm -v
```
To rebuild the image from the latest commits, run `docker-compose build --no-cache`, then start the containers with `docker-compose up`.
## Configuration Options
Below are configurations that can be added to the `.env` file in the project directory:
```
# Overrides the EL P2P port, default 30303
EL_P2P_PORT=30303
# Overrides the EL log level, default: 3
EL_LOG_LEVEL=4
# Overrides the CL P2P port, default: 9000
CL_P2P_PORT=9300
# Overrides the CL log level, default: info
CL_LOG_LEVEL=debug
# Add option to checkpoint sync from a remote BN
CHECKPOINT_SYNC_URL=http://host.docker.internal:5053
```
## How to test
### Request devnet-12 eth
Request some devnet eth from one of the faucets here:
https://dencun-devnet-12.ethpandaops.io/
### Sending Blobs
#### Nethermind's `SendBlobs`
Nethermind's `SendBlobs` tool can be found [here](https://github.com/NethermindEth/nethermind/tree/feature/send-blobs-tool/src/Nethermind/Nethermind.SendBlobs).
```
# Usage: docker run ghcr.io/flcl42/send-blobs:latest
# Example:
docker run ghcr.io/flcl42/send-blobs:latest http://localhost:8545 5 0x0000000000000000000000000000000000000000000000000000000000000000 0x000000000000000000000000000000000000f1c1
```
#### Blob-utils
To build `blob-utils`:
```
git clone https://github.com/Inphi/blob-utils.git
cd blob-utils
go build
# for Mac with Apple M1/M2 chips, build with these flags:
CGO_CFLAGS="-O -D__BLST_PORTABLE__" CGO_CFLAGS_ALLOW="-O -D__BLST_PORTABLE__" go build
```
To send a blob, replace `your_private_key` with your private key.
```
./blob-utils tx --rpc-url http://localhost:8545 \
--blob-file <(echo hello) \
--to 0x0000000000000000000000000000000000000000 \
--private-key \
--gas-limit 210000 \
--chain-id 7011893062 \
--priority-gas-price 200000000 \
--max-fee-per-blob-gas 300000000
```
### Downloading a blob via Beacon API

# look up by slot
curl http://localhost:5052/eth/v1/beacon/blob_sidecars/68267 | jq .
