ethereum-etl export data every time write over file. Filebeat always reload file then ELK receive repeat records…
So
.env STARTBLOCK=01205866 ENDBLOCK=01205888 startetl.sh IP_PORT is go-ethereum-node1 outside ip & port. here is docker-machine
source get file that path need to be careful
#!/bin/bash IP_PORT=192.168.99.100:18545 ETH_METHOD=eth_blockNumber BLOCKNUMBER_JSON_HEX=$(curl -X POST -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"'$ETH_METHOD'","params":[],"id":1}' $IP_PORT | jq '.result' | tr -d '"') BLOCKNUMBER_DEX=$(printf "%08d\n" $BLOCKNUMBER_JSON_HEX) printf "\n===== Now Geth BlockerNumber =====\n" printf "HEX: %s\n" $BLOCKNUMBER_JSON_HEX printf "DEC: %s\n" $BLOCKNUMBER_DEX source .

New docker use DOCKER-USER
Important!! check host route & login docker container check route. and iptables -L -t nat POSTROUTING MASQUERADE 172.17.0.0/16 must same submask. EX:
host route have 172.17.0.0, 172.18.0.0, 172.19.0.0, 172.20.0.0
docker insdie route use 172.18.0.0
iptables MASQUERADE use 172.17.0.0
Docker Internet is failed.
So add iptables -t nat -A POSTROUTING -s 172.18.0.0/16 ! -o docker0 -j MASQUERADE
#启动后默认增加的规则 iptables -N DOCKER iptables -N DOCKER-ISOLATION-STAGE-1 iptables -N DOCKER-ISOLATION-STAGE-2 iptables -N DOCKER-USER iptables -t nat -N DOCKER iptables -t nat -A PREROUTING -m addrtype --dst-type LOCAL -j DOCKER iptables -t nat -A OUTPUT !
