docker - Where does dockerized jetty store its logs? -


i'm packaging project docker jetty image , i'm trying access logs, no logs.

dockerfile

from jetty:9.2.10 maintainer me "me@me.com"  add ./target/abc-1.0.0 /var/lib/jetty/webapps/root  expose 8080

bash script start docker image:

docker pull me/abc docker stop abc docker rm abc docker run --name='abc' -d -p 10908:8080 -v /var/log/abc:/var/log/jetty me/abc:latest

the image running, i'm not seeing jetty logs in /var/log.

i've tried docker run -it jetty bash, not seeing jetty logs in /var/log either.

am missing parameter make jetty output logs or output somewhere other /var/log/jetty?

why aren't seeing logs

2 things note:

  1. running docker run -it jetty bash start new container instead of connecting existing daemonized container.

  2. and invoke bash instead of starting jetty in container, won't logs either container.

so interactive container won't in case.

but also...

jettylogs disabled anyways

also, won't see logs in standard location (say, if tried use docker exec read logs, or them in volume), quite because jetty docker file aptly disabling logging entirely.

if @ jetty:9.2.10 dockerfile, see line:

&& sed -i '/jetty-logging/d' etc/jetty.conf \

which nicely removes entire line referencing jetty-logging.xml default logging configuration.

what then?

reading logs docker logs

docker gives access container's standard output.

after did this:

docker run --name='abc' -d -p 10908:8080 -v /var/log/abc:/var/log/jetty me/abc:latest

you can this:

docker logs abc

and greeted somethig similar this:

running jetty:  2015-05-15 13:33:00.729:info::main: logging initialized @2295ms 2015-05-15 13:33:02.035:info:oejs.setuidlistener:main: setting umask=02 2015-05-15 13:33:02.102:info:oejs.setuidlistener:main: opened serverconnector@73ec519{http/1.1}{0.0.0.0:8080} 2015-05-15 13:33:02.102:info:oejs.setuidlistener:main: setting gid=999 2015-05-15 13:33:02.106:info:oejs.setuidlistener:main: setting uid=999 2015-05-15 13:33:02.133:info:oejs.server:main: jetty-9.2.10.v20150310 2015-05-15 13:33:02.170:info:oejdp.scanningappprovider:main: deployment monitor [file:/var/lib/jetty/webapps/] @ interval 1 2015-05-15 13:33:02.218:info:oejs.serverconnector:main: started serverconnector@73ec519{http/1.1}{0.0.0.0:8080} 2015-05-15 13:33:02.219:info:oejs.server:main: started @3785ms

use docker logs more details.

customize

obviously other option revert default dockerfile jetty doing, or create own dockerized jetty.

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.
