amazon web services - How to ensure to update Docker image on AWS ECS? -


i use docker hub store private docker image, repository has webhook once image updated calls service built to:

  • update ecs task definition
  • update ecs service
  • deregister old ecs task definition

the service running accordingly. after runs ecs creates new task new task definition, stops task old task definition , service come new definition.

the point docker image not updated, once service starts in new task definition remains old image.

am doing wrong? how o ensure docker image updated?

after analysing aws ecs logs found out problem in ecs docker authentication.

to solve i've added following data file /etc/ecs/ecs.config

ecs_cluster=default ecs_engine_auth_type=dockercfg ecs_engine_auth_data={"https://index.docker.io/v1/":{"auth":"your_docker_hub_auth","email":"your_docker_hub_email"}}

just replace your_docker_hub_auth , your_docker_hub_email own information , shall work properly.

to find information can execute docker login on own computer , data in file ~/.docker/config.json

for more information on private registry authentication topic please @ http://docs.aws.amazon.com/amazonecs/latest/developerguide/welcome.html

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
