This problem seems to have been introduced in #11918

I also have the same issue.

For me using

version: '3.7'
  vitess-8:
    image: vitess/vttestserver:mysql80
    restart: always
    ports:
      - 33807:33807
    healthcheck:
      test: ['CMD', 'mysqladmin', 'ping', '-h127.0.0.1', '-P33577']
      interval: 5s
      timeout: 2s
      retries: 5
      start_period: 25s
    environment:
      PORT: '33804'
      KEYSPACES: 'unsharded' 
      NUM_SHARDS: '1' 
      MYSQL_BIND_HOST: '0.0.0.0'
      FOREIGN_KEY_MODE: 'disallow'

Used to work before and now errors when doing docker-compose up -d vitess-8

Relevant error from the logs:

@Jolg42 As a work around until this PR #12004 is merged, just specify an additional environment variable TABLET_REFRESH_INTERVAL to 10s.

Thanks, @GuptaManan100, I can confirm adding this under environment to my docker-compose vitess definition works

      TABLET_REFRESH_INTERVAL: '10s'
