This AMI is for developing IOST Dapp, including iServer and iWallet.
It contains the iServer docker image (iostio/iost-node).
IServer is automatically launched via docker, and it creates a local IOST blockchain for testing.
You may use iWallet to check current status: iwallet state.
Or to get logs of iServer: tail -f /data/iserver/logs/iost.log.
You may also want to upgrade to the latest release using the one-button script.
