linux - Run docker in ubuntu live disk -


i wondering if it's possible install , run docker in ubuntu 14.04 usb live-disk.

i'm trying 8gb usb, 4 gb installation , 4 gb persisted storage, keep getting errors when running containers (no problem in pulling them).

here docker version:

$ sudo docker version client version: 1.6.2 client api version: 1.18 go version (client): go1.4.2 git commit (client): 7c8fca2 os/arch (client): linux/amd64 server version: 1.6.2 server api version: 1.18 go version (server): go1.4.2 git commit (server): 7c8fca2 os/arch (server): linux/amd64

and current error i'm getting when running docker container is:

[8] system error: mountpoint cpu not found

obs: error cpuset or devices not found.

the kernel of live-disk i'm using is:

$ uname -r 3.13.0-32-generic

if ubuntu live disk not best live-disk run docker, there any other alternatives have gui it, not simple terminal run docker?

i'm saying because i'm trying introduce docker parents, don't want install linux in pcs, , need simple graphic interface write down dockerfile, open browser, etc...

update

i saw during install there error when setting cgroup-lite dependency initctl: unknown job: cgroup-lite. read ubuntu need install apparmor docker installation works properly.

so installed , reinstalled docker (cgroup-lite installed no problem then), , i'm getting when running sudo docker -d

info[0000] +job serveapi(unix:///var/run/docker.sock)    info[0000] listening http on unix (/var/run/docker.sock)  info[0000] +job init_networkdriver()                     info[0000] -job init_networkdriver() = ok (0)            warn[0004] kernel not support cgroup swap limit.  info[0004] loading containers: start.                    ...... info[0004] loading containers: done.                     info[0004] docker daemon: 1.6.2 7c8fca2; execdriver: native-0.2; graphdriver: aufs  info[0004] +job acceptconnections()                      info[0004] -job acceptconnections() = ok (0)             info[0004] daemon has completed initialization

and when trying run container receive>

erro[0125] http error: statuscode=500 cannot start container 90875e79dec37cec41a67aac235b81f0fc17c4e011cd6e5368a4b29336587f5b:  [8] system error: permission denied

not sure kernel not supporting cgroup, if so, possible update kernel in livedisk (persisting it?) ?

i've managed make work changing docker storage devicemapper instead of aufs.

basically had change /etc/default/docker have in it:

docker_opts="--storage-driver=devicemapper"

i've manage make containers run ok this, prefer using aufs.

i realized partition not using aufs default, caw or cow (can't remember now).

i tried make work using aufs using union=aufs flag in grub, when running docker daemon fata[0000] shutting down daemon due errors: error intializing graphdriver: backing file system unsupported graph driver, looks related https://github.com/docker/docker/issues/7321

i'll leave answer here, since workaround problem, if manage make work using aufs be, in opinion, better answer.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
