Ошибка образа докера ivankrizsan/elastalert

Я пытаюсь использовать elastalert в качестве док-контейнера, используя compose. Ниже приводится определение elastalert в моем файле dokcer-compose: elastalert:

image: ivankrizsan/elastalert
container_name: elastalert
restart: unless-stopped
privileged: true
links:
  - es:elasticsearchhost
ports:
  - "3030:3030"            
cap_add:
  - SYS_TIME
  - SYS_NICE
volumes:
  - /etc/elastalert/config:/opt/config
  - /etc/elastalert/rules:/opt/rules
  - /etc/elastalert/logs:/opt/logs
  - /etc/elastalert:/opt/elastalert
environment:
  - ELASTICSEARCH_HOST=es
  - ELASTICSEARCH_PORT=9200  

Я получаю следующую ошибку:
