InfluxDB docker 容器重新启动后，它没有恢复到最后一点，并且它也有挂载卷

Question

我有一个容器作为 Influxdb 2.0，并且我已经安装了卷，以防我们必须关闭容器。下面我向您展示了我的 docker-comopose.yml 文件。你可以看到我已经安装了卷，但最近我已经关闭了所有容器，然后又启动了，但我没有在 Influxdb 中获取旧数据，我正在获取其他容器的数据，如 telegraf 和 grafana

version: "3"
services:
  grafana:
    image: grafana/grafana:7.4.0-ubuntu
    container_name: grafana
    restart: always

    environment:

    links:

  grafana-storage:

  telegraf-storage:

使用 docker logs influxdb 检查时出现错误

Answer 1

实际上，Influxdbv2 的所有默认配置都位于 /root/.influxdbv2 位置。所以我们需要挂载这个卷，但是有两种方法可以实现。

• 在您的influxdb container 中设置环境变量INFLUXD_BOLT_PATH 和INFLUXD_ENGINE_PATH 以指向您的卷挂载目录之一
• 将卷挂载更改为挂载到/root/.influxdbv2

我选择了第二个选项，之后我的数据将保持不变，无论我关闭和启动 Influxdb Container 多少次。

谢谢
