How to recover Tarantool docker when computer crashed?

I got this when starting tarantool using docker compose:

full_tarantool_1 exited with code 1

the docker-compose.yml

version: '2'
services:
  tarantool:
    image:  tarantool/tarantool:2.6.0
    ports:
      - 3301:3301
    volumes:
      - /var/local/foo/tarantool:/var/lib/tarantool

Is there a way to prevent this from happening in the future?

Solution

Try to use force_recovery_option (it could be passed via TARANTOOL_FORCE_RECOVERY env variable). Note that it's a dangerous option -backup your xlog/snap files before to be able to recover your data if my advice will be unsuccessful.
