networking - Network connectivity for docker containers on Ubuntu VM -


i have installed docker on ubuntu vm. running ubuntu docker containers. ip address taken these docker container in 172.17.*.* (eth0). ip not able ping/access docker container outside.
hence trying assign ip local network range. followed steps:

  • create new bridge network subnet , gateway ip block

    $ docker network create --subnet 10.255.*.0/24 --gateway 10.255.*.254 ipstatic

  • run ubuntu container specific ip in block

    $ docker run --rm -it --net ipstatic --ip 10.255.*.2 phusion/ubuntu

  • curl ip other place (assuming public ip block duh)

    $ curl 10.255.*.2

curl: (7) failed connect 10.255.*.2 port 80: connection refused

with this, host unable access 10.255.*.* network.the docker container takes ip 10.255.*.2, still unable access outside. newbie docker. aim access docker containers to-from local network.

you can specify network_mode: "host" when create container. available @ same ip host. have make sure doesn't try listen port that's in use.

eg:

version: "2" services:   myapp1:     network_mode: "host"     etc

however, it's practice treat host fortress , limit containers directly accessible outside world. keep nginx @ public face instance , keep other containers in private internal network. wrote answer few minutes ago.

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
