I followed the production node setup guide, but I encountered an error when running the command "sudo docker compose --env-file $ZKEVM_CONFIG_DIR/.env -f $ZKEVM_DIR/$ZKEVM_NET/docker-compose.yml up -d" What can I do to resolve this?

It seems like there are a few issues with the directory structure and environment variables. Follow these steps to set up the environment correctly:

Create a directory inside your home directory:

mkdir -p /$HOME/zkevm-node

Move inside this directory and create four subdirectories:

mkdir -p /$HOME/zkevm-nodezkevm_config zkevm_statedb zkevm_pooldb

Set these three environment variables in your terminal session:

ZKEVM_NET=testnet
ZKEVM_DIR=$HOME/zkevm-node/zkevm
ZKEVM_CONFIG_DIR=$HOME/zkevm-node/zkevm_config

Download the required resources:

curl -L https://github.com/0xPolygonHermez/zkevm-node/releases/latest/download/$ZKEVM_NET.zip > $ZKEVM_NET.zip && unzip -o $ZKEVM_NET.zip -d $ZKEVM_DIR && rm $ZKEVM_NET.zip

Create a new file using the command vim $ZKEVM_CONFIG_DIR/.env and enter the following values (replace <GOERLI_RPC_URL_HERE> with your Goerli RPC URL):

ZKEVM_NODE_STATEDB_DATA_DIR=$HOME/zkevm-node/zkevm_statedb
ZKEVM_NODE_POOLDB_DATA_DIR=$HOME/zkevm-node/zkevm_pooldb
ZKEVM_NODE_ETHERMAN_URL=<GOERLI_RPC_URL_HERE>
ZKEVM_NETWORK=testnet

Now you should be able to run the containers with the docker command listed in the documentation (Step 5 onwards).
