Docker로 tendermint 실행

없다캐라 2020. 11. 30. 14:45

tendermint의 멀티노드 테스트 환경을 구축하기 위해 docker를 사용하는 과정을 정리해 보았습니다.

docker 에서 실행

tendermint multi container

init

user 디렉토리 밑에 각 컨테이너의 설정을 담기 위해 tendermint1~tendermint3 까지 디렉토리를 생성합니다. 이후 tendermint init 으로 default 설정 및 data 디렉토리를 생성합니다.

docker run -it --rm -v "/Users/kmpak/tmp/tendermint1:/tendermint" tendermint/tendermint init
docker run -it --rm -v "/Users/kmpak/tmp/tendermint2:/tendermint" tendermint/tendermint init
docker run -it --rm -v "/Users/kmpak/tmp/tendermint3:/tendermint" tendermint/tendermint init

docker run -it --rm -v "/Users/kmpak/tmp/tendermint1:/tendermint" tendermint/tendermint show_node_id
docker run -it --rm -v "/Users/kmpak/tmp/tendermint2:/tendermint" tendermint/tendermint show_node_id
docker run -it --rm -v "/Users/kmpak/tmp/tendermint3:/tendermint" tendermint/tendermint show_node_id

init 이후 show_node_id 명령어로 노드에 대한 address( ?) 값을 구해옵니다. 이걸로 아래의 config 파일에 입력하기 위해서 입니다.

config

tendermint1 ~ 3 까지 config 디렉토리에서 몇몇 설정을 맞춰줍니다.

이 부분은 tendermint 설정을 어느정도 이해하고 있어야 하는데 docker 를 떠나서 멀티노드 구성에 대한 설정을 이해해야 할 수 있는 작업입니다.

같은 Network에서 통신하는 node들은 같은 genesis.json 파일을 참조해야 합니다.

user-defined bridge networks

멀티노드 설정 작업이 끝나면 이후 docker container 간 원활한 네트웍 통신을 위해 network group 를 만듭니다. Networking with standalone containers 참조

docker network create --driver bridge tmnet

run

config과 네트웍 그룹으로 실행을 시킵니다. port는 컨테이너 안에서는 모두 26657 port 이겠지만 host에서 달리 접근하기 위해서는 26617, 26627, 26637 로 매핑시켰습니다.

docker run -it -p 26617:26657 -h tm1 --name tm1 --network tmnet --rm -v "/Users/kmpak/tmp/tendermint1:/tendermint" tendermint/tendermint node --proxy_app=kvstore

docker run -it -p 26627:26657 -h tm2 --name tm2 --network tmnet --rm -v "/Users/kmpak/tmp/tendermint2:/tendermint" tendermint/tendermint node --proxy_app=kvstore

docker run -it -p 26637:26657 -h tm3 --name tm3 --network tmnet --rm -v "/Users/kmpak/tmp/tendermint3:/tendermint" tendermint/tendermint node --proxy_app=kvstore

transaction 발생

host terminal 에서 트랜잭션을 날려보면 됩니다. 가령 tm1 에 붙고 싶을 때는 26617 로….. tm3에 붙고 싶으면 26637로 접근하면 됩니다.
