Question

我已经为我的节点应用程序设置了一个Docker容器并使用

运行它

import matplotlib
matplotlib.use("TkAgg")
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, 
NavigationToolbar2Tk
from matplotlib.figure import Figure
import matplotlib.animation as animation
from matplotlib import style
import random

LARGE_FONT= ("Verdana", 12)
style.use("ggplot") #ggplot...dark_background

do = []
tempF= []

f = Figure(figsize=(10,6), dpi=100)
a = f.add_subplot(111)

arduinoData = serial.Serial('com3', 115200) #Creating our serial object 



def animate(i):

  if(arduinoData.inWaiting()>0):

#read serial data
arduinoString = arduinoData.readline()
xList = []
yList = []



#Parse serial data
arduinoString.split()
['', '', '', '', '', '', '', '']
words = arduinoString.split()

reading = words[3]

if words[1] == (b'TEMP') :
    print (words[0])
    print (words[1])
    print (words[3])
    tempF.append(reading)                  #Build our tempF array by appending temp readings

a.clear()
a.plot(*yList, *yList)   


title = "    D.O : "+str(do) + "\n Temp : " + str(tempF)
a.set_title(title)




arduinoData.flushInput()
arduinoData.flushOutput()




class Application(tk.Tk):

def __init__(self, *args, **kwargs):
    tk.Tk.__init__(self, *args, **kwargs)
    tk.Tk.wm_title(self, "Stylibleue Dashboard")


    # the container is where we'll stack a bunch of frames on top each other
    container = tk.Frame(self)
    container.pack(side="top", fill="both", expand = True)
    container.grid_rowconfigure(0, weight=1)
    container.grid_columnconfigure(0, weight=1)

    #Switch through pages
    self.frames = {}

    for F in (StartPage, Page1,):

        frame = F(container, self)

        self.frames[F] = frame

        frame.grid(row=0, column=0, sticky="nsew")

    self.show_frame(StartPage)

def show_frame(self, cont):

    frame = self.frames[cont]
    frame.tkraise()



class StartPage(tk.Frame):

def __init__(self, parent, controller):
    tk.Frame.__init__(self, parent)

    #Page Labels
    label = tk.Label(self, text=("""     D.O : 
    """), font=LARGE_FONT)
    label.grid(row=100, column=20, sticky="nsew")

    label = tk.Label(self, text=("""<Sensor reading here>
    """), font=LARGE_FONT)
    label.grid(row=100, column=30, sticky="nsew")

    label = tk.Label(self, text=(""" TEMP : 
    """), font=LARGE_FONT)
    label.grid(row=100, column=40, sticky="nsew")

    label = tk.Label(self, text=("""<Sensor reading here>        
    """), font=LARGE_FONT)
    label.grid(row=100, column=50, sticky="nsew") 


    #Go to Page1 button
    button1 = ttk.Button(self, text="Page1",
                        command=lambda: controller.show_frame(Page1))
    button1.grid(row=100, column=60, sticky="nsew")



class Page1(tk.Frame):

def __init__(self, parent, controller):
    tk.Frame.__init__(self, parent)
    label = tk.Label(self, text="Bassin 2!!!", font=LARGE_FONT)
    label.pack(pady=10,padx=10)

    #Return home button
    button1 = ttk.Button(self, text="Back to Home",
                        command=lambda: controller.show_frame(StartPage))
    button1.pack()


    #This is the embedded matplotlib graph
    canvas = FigureCanvasTkAgg(f, self)
    canvas.draw()
    canvas.get_tk_widget().pack(side=tk.BOTTOM, fill=tk.BOTH, expand=True)

    toolbar = NavigationToolbar2Tk(canvas, self)
    toolbar.update()
    canvas._tkcanvas.pack(side=tk.TOP, fill=tk.BOTH, expand=True)




app = Application()
ani = animation.FuncAnimation(f, animate, interval=1000)
app.mainloop()

它以无守护进程模式启动了pm2。 CTRL + C并退出不起作用。我试过docker在另一个终端窗口中停止my_node_app，但无济于事。感谢任何帮助。

Answer 1

您将可以使用以下命令查看当前正在运行的Docker容器。

docker ps

然后复制正在运行的容器的容器ID，并执行以下命令

docker stop <container_id>

请替换为真实值。

Answer 2

如果尚不知道，请执行docker container ls查找容器名称，然后docker kill container_name。

来源：Docker documentation

Answer 3

您可以尝试这个非常简单的脚本

docker container kill $(docker ps | grep "image_name" | awk '{print $1}')

解释

以表格结构列出容器

docker ps

结果

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                 NAMES
763e1a00808e        7bb2586065cd        "docker-entrypoint.s…"   2 months ago        Up 2 weeks          3306/tcp, 33060/tcp   mysql_1
763e1a00999b        7bb2586065cd        "docker-entrypoint.s…"   1 months ago        Up 2 weeks          3307/tcp, 33061/tcp   mysql_2

隔离容器

grep "mysql_1"

结果

STATUS              PORTS                 NAMES
763e1a00808e        7bb2586065cd        "docker-entrypoint.s…"   2 months ago        Up 2 weeks          3306/tcp, 33060/tcp   mysql_1

隔离第一个制表符值，即容器ID awk'{print $ 1}'

结果

763e1a00808e

因此，总而言之，这将隔离并发送kill或stop命令与图像名称匹配的容器ID

Answer 4

“Docker 容器 ls” 查看现有容器
“Docker container kill container_id”强制终止或“docker container stop container_id”正常终止

杀死一个Docker容器
