Add new command to CMD without overriding existing


Add new command to CMD without overriding existing



I'm want to use existing docker image and add new command without overiding commands in cmd.



Dockerfile


FROM telegrammessenger/proxy

COPY mtproto_stats .

CMD [ "/bin/sh", "-c", "/bin/bash /run.sh", "/bin/bash ./mtproto_stats" ]



Here i try to execute my programm which i copied to container CMD [ "/bin/sh", "-c", "/bin/bash /run.sh", "./mtproto_stats" ]



This commands "/bin/sh", "-c", "/bin/bash /run.sh" i got using docker inspect on running container


"/bin/sh", "-c", "/bin/bash /run.sh"


docker inspect



My programm should run with container and work all time, i'm trying use "./mtproto_stats & disown" but it not help


"./mtproto_stats & disown"





It's not clear what you are trying to achieve.

@dpwrussell run /run.sh an then ./mtproto_stats, but ./mtproto_stats run only if i put it to entrypoint, but if put it to entrypoint /run.sh will not run

/run.sh


./mtproto_stats


./mtproto_stats


/run.sh





I don't think you understand what entrypoint and command actually do and also how command works. command is not a list of commands, it is a single command. If you want your container to do two things then you will need to make a run-script that you make the entrypoint. The run-script will then launch run.sh and then mtproto_stats, either one after the other, or if one/both are services, then by using one of many techniques to detach those processes.

This commands "/bin/sh", "-c", "/bin/bash /run.sh" i got using docker inspect on running container


"/bin/sh", "-c", "/bin/bash /run.sh"



"/bin/sh", "-c" is the default ENTRYPOINT, "/bin/bash /run.sh" is the CMD.


"/bin/sh", "-c"


ENTRYPOINT


"/bin/bash /run.sh"


CMD



In your case, you should have, using the shell form of CMD:


FROM telegrammessenger/proxy

COPY mtproto_stats .
COPY wrapper.sh /wrapper.sh
CMD exec /wrapper.sh



With wrapper.sh:


#!/bin/bash
exec /path/to/mtproto_stats & disown
exec /run.sh



I place run.sh at the end, as it is supposed to be the main process, which keep the container alive.


run.sh

How to input without newline? (Python)

How to input without newline? (Python) I am trying to create a simple file editor in Python via the console (called PyCons). Here is my current program: def PyCons(f): file = open(f, "r") appe = open(f, "a") print("n=====nPyCons Editor, v1.2nPython 3.6.1n") global i i = 0 for line in file: i += 1 print(" {}| ".format(i) + line, end='') for k in range(10000000000000): print("n {}| ".format(i+1), end='') inp = input("") if inp == "@PyCons.save()": print("n=====") break else: i += 1 appe.write("n" + inp) I used the end method to make sure that the existing code in the file was printed properly in its line format, but the input function does not have an end attribute. So, when I go to enter code in the editor: end input end PyCons("magic.html") ... ===== PyCons Editor, v1.2 Python 3.6.1 1| <p>Hello!...
