google container engine - Deploying service to GKE/Kubernetes leading to FailedSync error -

-

when deploying service kubernetes/gke kubectl describe pod indicates following error (as occurring after image pulled):

{kubelet <id>} warning failedsync error syncing pod,  skipping: failed "startcontainer" "<id>" crashloopbackoff:  "back-off 20s restarting failed container=<id>" {kubelet <id>}  spec.containers{id} warning backoff restarting failed docker container.

i have checked various log files (such /var/log/kubelet.log , /var/log/docker.log) on node pod executing did not find more specific?

what error message indicate, , how can further diagnose , solve problem?

the problem might in relation mounting pd. can both docker run the image cloud shell (without pd) , mount pd after adding gce vm instance. apparently it's neither caused image nor pd in isolation.

the root cause apparently pd did not contain directory target of symbolic link required application running inside image. cause application terminate , effect image stop, apparently reported failed docker container in shown log file.

after creating directory (by attatching drive separate vm instance , mounting there purpose) specific problem disappears (only followed this 1 :)

Android volley - avoid multiple requests of the same kind to the server? -

-
i using volley upload list of images server. happens within service. once image uploaded remove list. problem arises when internet connection breaks. when internet connection breaks , comes again thinking of adding images yet uploaded request queue. this can result in more 1 copy of same image saved on server request same image might have gone through before getting rseponse. how can address scenario? i'm not quite sure why you're using service schedule requests volley automatically runs it's request in seperate thread. nevertheless can listen both request results, successful , unsuccessful adding listeners. you can remove image list schedule request using volley. if succeeds can carry on desired, if fails can add again list. public static request getimageuploadrequest(final string image) { response.listener<t> responselistener = new response.listener<t>() { @override public void onresponse(t response
