Я пытаюсь запустить сеть hyperledger fabri c в Linux (RHEL 7) машине с docker-compose. Но одноранговые контейнеры выходят через некоторое время. В логах контейнера peer я вижу ошибку ниже.

Я подозревал, что в контейнере docker может быть проблема с DNS. Поэтому я также попытался добавить dns_search: . и - GODEBUG=netdns=go в файл docker-compose.yaml.
peer0.org1.example.com:
container_name: peer0.org1.example.com
image: hyperledger/fabric-peer:1.4.4
dns_search: .
environment:
- GODEBUG=netdns=go

Это все та же ошибка.
