Ошибка подключения Debezium Kafka - TimeoutException: истекло время ожидания при получении метаданных topi c

/ 24 января 2020

Я получаю сообщение об ошибке на Debezium Connect, и не знаю, где я делаю ошибку или что-то упускаю. Ниже приведены свойства моего коннектора и файла docker. Возможно ли, что docker, развернутая на виртуальной машине, не может подключить ее к базе данных на другой виртуальной машине?

Ошибка говорит, что не удается подключиться к Кафке.

Следующим не следует применять к ним https://

  • CONNECT_BOOTSTRAP_SERVERS
  • CONNECT_CONSUMER_SSL_ENDPOINT_IDENTIFICATION_ALGORITHM
  • CONNECT_PRODUCER_SSL_ENDPOINT_IDENTIFICATION_ALGORITHM

На самом деле, даже не уверен, что последние два являются допустимыми конфигами.

Вы также можете удалить REQUEST_TIMEOUT_MS и RETRY_BACKOFF_MS конфиги, если у вас нет специального c варианта использования для установки этих

И AFAIK, CONFIG_PROVIDERS_FILE_CLASS не требуется, поскольку файл является реализацией по умолчанию.

Совет: используйте файл .env, чтобы уменьшить количество переменных, необходимых в YAML
