Вопрос:

Я пытаюсь смонтировать конфигурацию моего экспортера blackbox с хостом, но он выдает ошибку.

Вот мой файл Docker Compose:

   blackbox_exporter:
    image: prom/blackbox-exporter
    container_name: blackbox-exporter
    volumes:
      - /etc/blackboxexporter/:/home/huzaifakhan/dockprom/prometheus/
    command:
      - '--config.file=/etc/blackboxexporter/config.yml'
    restart: unless-stopped
    dns: 8.8.8.8
    expose:
      - 9115
    networks:
      - monitor-net
    labels:
      org.label-schema.group: "monitoring"

Ответ №1:

В volumes: разделе вашего docker-compose файла поменяйте местами каталоги. Сначала должен быть каталог хоста, затем каталог контейнера.

И config.yml он должен существовать в каталоге хоста. Просто скопируйте и вставьте его на хост из контейнера, выполнив:

 docker exec <container-name> cat /etc/blackboxexporter/config.yml

В принципе, в конце это должно выглядеть так:

 volumes:
    - /home/.../your-directory:/etc/container-directory

/home/.../your-directory должен содержать config.yml файл

Если это так, у вас будет файл конфигурации /etc/container-direcory , когда он будет запущен, и вы не получите сообщение об ошибке выше.

1. Я также пытаюсь поместить сначала каталог хоста, а затем каталог контейнера, но это никак не влияет на него.

2. @huzaifa224 Я изначально неправильно понял проблему, отредактировал ответ.
