docker - CoreOS Unit Failed on Launched -


i tried launching service using chat.service unit file on coreos , failed:

// chat.service [unit] description=chatapp  [service] execstartpre=-/usr/bin/docker kill simplechat1 execstartpre=-/usr/bin/docker rm simplechat1 execstartpre=-/usr/bin/docker pull jochasinga/socketio-chat execstart=/usr/bin/docker run -p 3000:3000 --name simplechat1 jochasinga/socketio-chat

fleetctl list-units shows:

unit            machine                     active  sub chat.service    cfe13a03.../<virtual-ip>    failed  failed

however, if changed chat.service just:

// chat.service [service] execstart=/usr/bin/docker run -p 3000:3000 <mydockerhubuser>/socketio-chat

it ran fine. fleetctl list-units shows:

unit            machine                     active  sub chat.service    8df7b42d.../<virtual-ip>    active  running

edit using journalctl -u chat.service got:

jun 02 00:02:47 core-01 systemd[1]: started chat.service. jun 02 00:02:47 core-01 systemd[1]: chat.service: main process exited, code=exited, status=125/n/a jun 02 00:02:47 core-01 docker[8924]: docker: error response daemon: failed create endpoint clever_tesla on network brid jun 02 00:02:47 core-01 systemd[1]: chat.service: unit entered failed state. jun 02 00:02:47 core-01 systemd[1]: chat.service: failed result 'exit-code'. jun 02 00:02:58 core-01 systemd[1]: stopped chat.service. jun 02 00:03:08 core-01 systemd[1]: stopped chat.service.

what had done wrong in first chat.service unit file? guidance appreciated.

running vagrant version of coreos (stable) on mac os x.

your execstartpre= command doesn't seem have docker subcommand in it. did mean use pull?

reading journal unit should more information: journactl -u chat.service

Sure, some authors could pull it off, but if you worked at an office, what were you supposed to do? Go to work with a bag over your head?

Google AdWords and AdSense - A Dynamic Small Business Marketing Duo

Unless you have been living under a rock for the last year or so, you probably know that Google has become the king of the search engine hill. There are many reasons for this but number one in my opinion is that above all else they put value on content. Today I want to introduce you to two very powerful small business advertising options created by Google. These two ingenious programs have all but revolutionized the way advertising is done on the web. Warning: If you are thinking..."web advertising isn't for me, I just need a few more clients around the block"...you better read this or be prepared to have your competitors eat your lunch. Goolge AdSense - Again content is king at Google. This program allows web site "publishers" to add some code from Google and receive "content relevant" ads on their site from other site owners.
