Question

我想在docker中运行apache-ignite，并且我能够做到这一点。但是问题是，只要我旋转图像并在点燃时创建表，只要容器正在运行，它就会一直停留在该位置。如果我重新启动容器或再次启动点燃图像，则无法获取该数据。我知道每当旋转图像时，它总是创建新的容器。就我而言，如果我要保留数据，则需要提交并推送容器，以便下次启动时可以获取它。

但是有什么办法，我可以在主机系统上存储点火数据，并且每当我启动映像时，它将在该位置读取/写入数据（简短的批量安装）。

任何人都可以分享示例的经验或想法吗？谢谢。

我将它与docker-compose一起使用，下面是我的docker-compose.yml文件。

version: "3.7"
services:
  ignite:
    image: apacheignite/ignite
    environment:
      - IGNITE_QUIET=false
    volumes:
      - "./ignite-main.xml:/opt/ignite/apache-ignite/config/default-config.xml"
    ports:
      - 11211:11211
      - 47100:47100
      - 47500:47500
      - 49112:49112

如果我运行docker-compose up命令，则会出现以下错误。

@Update 您好，经过大量RnD处理后，我能够解决此问题。下面是我做的配置1. docker-compose.yml

# !/usr/bin/python
from gurobipy import *

# Create the model to be used in the terminal
m = Model("777x Optimization")

# Name and Create the variables
x1 = m.addVar(name="First-Class Seat Pitch [in]")
x2 = m.addVar(name="First-Class Seat Width [in]")
x3 = m.addVar(name="First-Class Seat Thickness [in]")
x4 = m.addVar(name="Premium-Economy Seat Pitch [in]")
x5 = m.addVar(name="Premium-Economy Seat Width [in]")
x6 = m.addVar(name="Premium-Economy Seat Thickness [in]")
x7 = m.addVar(name="Number of First-Class Rows")
x8 = m.addVar(name="Number of Premium-Economy Rows")
x9 = m.addVar(name="Number of First-Class Seats Per Row")
x10 = m.addVar(name="Number of Premium-Economy Seats per Row")

# Set objective: f(x1,x2,x3,x4,x5,x6,x7,x8)
obj = x7*x9*(x1+x2+x3) + x8*x10*(x4+x5+x6)
m.setObjective(obj, GRB.MINIMIZE)

# Add constraints
m.addConstr((x7*x1*x2)+(x4*x5*x8) <= 342625, "Area Constraint")
m.addConstr(1512*x8 + 5410*x7 >= 202182, "Ticket Revenue             Constraint")
m.addConstr(0.25*x5 + 0.35*x6 +0.4*x4 >= 18.6975, "Premium-Economy    Comfort Level Constraint")
m.addConstr(0.25*x2 + 0.35*x3 +0.4*x1 >= 29.16, "First-Class Economy Comfort Constraint")
m.addConstr(x8 - 1.4*x7 >= 0 , "Ratio of First Class to Economy Class Seats Constraint")
m.addConstr(x1 >= 57, "Minimum First-Class Pitch Constraint")
m.addConstr(x2 >= 25, "Minimum First-Class Width Constraint")
m.addConstr(x3 >= 3, "Minimum First-Class Thickness Constraint")
m.addConstr(x4 >= 36, "Minimum Premium-Economy Pitch Constraint")
m.addConstr(x5 >= 18.5, "Minimum Premium-Economy Width Constraint")
m.addConstr(x6 >= 1.5, "Minimum Premium-Economy Thickness Constraint")
m.addConstr(x9*x2 <= 233.04, "Seats Per Aisle Constraint First-Class")
m.addConstr(x10*x5 <= 233.04, "Seats Per Aisle Constraint Premium-Economy")
m.optimize()

for v in m.getVars():
    print('%s %g' % (v.varName, v.x))

print('Obj: %g' % obj.getValue())

ignite_1.xml以确保数据持久性

version: "3.5"
    services:
      ignite:
        image: apacheignite/ignite
        environment:
          - IGNITE_QUIET=false

        volumes:
          - ignite-persistence-1:/opt/ignite/
          - "./ignite_1.xml:/opt/ignite/apache-ignite/config/default-config.xml"

        ports:
          - 11211:11211
          - 47100:47100
          - 47500:47500
          - 49112:49112

        deploy:
          replicas: 1
          restart_policy:
            condition: on-failure
            delay: 30s
            max_attempts: 10
            window: 180s

    volumes:
      ignite-persistence-1:

我将docker-compose.yml和ignite_1.xml保留在同一目录中，并从该目录打开终端并执行以下命令。

通过使用 ignite-persistence-1：/ opt / ignite / ，即使停止或关闭docker-compose，我也能够保留数据。

我希望这也会对其他人有所帮助。

谢谢。
