安排容器的问题

Question

我的Docker-Compose看起来像这样：

version: '3.7'

services:
  app:
    container_name: container1
    #restart: unless-stopped
    build:
      context: .
      dockerfile: Dockerfile
    labels:
      ofelia.enabled: "true"
      ofelia.job-exec.app.schedule: "@every 30m"
      ofelia.job-exec.app.command: "/app/Final_DM_For_All_Clients.py"

  ofelia:
    image: mcuadros/ofelia:latest
    #restart: unless-stopped
    depends_on:
      - app
    command: daemon --docker
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:r

第一次运行后，第二次作业跑步不会在30分钟内发生，我得到了 在第二次运行中以下错误。

container1-ofelia-1  | 2022-05-24T22:59:02.037Z  common.go:121 ▶ ERROR [Job "app" (3d8aab0fe293)] Finished in "3.322350449s", failed: true, skipped: false, error: error creating exec: API error (409): Container 65f90ee04e25d1164d29ab911197d239873da3eafbc34823873d3ba2d791a0ad is not running

我的Docker文件看起来像这样：

FROM python:3.8

COPY . /app
WORKDIR /app

ADD df_curr.csv .
ADD df_prev.csv .
ADD df_roster.csv .
ADD df.csv .
ADD manager_name.csv .
ADD name_data.csv .

EXPOSE 8080 

CMD python Final_DM_For_All_Clients.py

第一次运行后，具有代码0的容器退出，表示成功运行，但在第二个计划运行IE IE IE时，由于容器停止，Scheduler无法在第二个脚本中运行该脚本跑步。

我认为问题是您正在使用Ofelia的exec作业，该作业试图将docker exec纳入运行容器，该容器失败。

您正在寻找的是运行作业，根据 docs ，运行新容器或启动现有容器。因此，我相信您应该更改标签的定义：

ofelia:
   ...  # Your configs

   labels: 
      ofelia.enabled: "true"
      ofelia.job-run.app.schedule: "@every 30m"
      ofelia.job-run.app.container: "container1"

   ...  # Your configs

文档说您在尝试执行container参数时必须在尝试执行Docker Start时传递。我不确定您第一次运行时如何播放，但是我假设app是第一次和以后的时间 ofelia 再次启动容器。
