handle docker container data while developing wep application -

-

i pulled image magento2 installation.

now trying container /var/www/html data in host after can handle phpstorm.

i tried overwrite in container /var/www/html 

docker run --name development-phase -d -p 5000:80 -v /u01/magento2:/var/www/html magento2

while creating volume

data flows: host /u01/magento2 container /var/www/html

but looking

data flow should be container /var/www/html host /u01/magento2

i have referred stack overflow link suggest copy container data host before creating volume, in case docker cp command affect prerequisite setting of magento2 page not load properly.

that's behavior of volumes in docker:

  • -v /host/path:/container/path not copy data
  • -v /container/path copy data , creates new volume random name

so, might want try

docker run --name development-phase -d -p 5000:80 -v /var/www/html magento2

then find out random path looking @ value of property source "destination":"/var/www/html" using docker inspect

docker inspect --format "{{json .mounts}}" development-phase

even more readable 

docker inspect -f "{{json .mounts}}" development-phase \  | jq '.[] | select(.destination | contains("/var/www/html"))'

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...
