这是我的 Docker 撰写文件：

  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"

Answer 1

在您的docker-compose文件的volumes:部分中，切换目录的位置。 主机目录应该首先出现，然后是容器目录。

而且， config.yml必须存在于主机目录中。 只需通过运行将其从容器复制并粘贴到主机：

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

基本上，最后，它应该是这样的：

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

/home/.../your-directory应该包含config.yml文件

如果是这种情况，您将在/etc/container-direcory中，并且不会出现上述错误。
