ansible-playbook --limit not working with overlapping host aliases -

-

im having problem limiting ansible work specific host

my inventory file looks this:

[staging-docker-containers] app1 ansible_host=host.domain.com ansible_ssh_port=2222   app2 ansible_host=host.domain.com ansible_ssh_port=2223   app3 ansible_host=host.domain.com ansible_ssh_port=2224    [staging-other-servers] app1 ansible_host=host.domain.com ansible_ssh_port=2225   app2 ansible_host=host.domain.com ansible_ssh_port=2226   app3 ansible_host=host.domain.com ansible_ssh_port=2227

when run follow command

ansible-playbook --limit="staging-docker-containers:app3"  my-playbook.yml -i staging

it ignores limit command , tries connect app3 under staging-other-servers group, , not app3 under staging-docker-containers group.

am doing wrong?

you can have same host in different groups.
can't have different hosts under same name.
if define same host variables same host in different places, latter have priority.
inventory becomes:

[staging-docker-containers] app1 app2 app3  [staging-other-servers] app1 ansible_host=host.domain.com ansible_ssh_port=2225 app2 ansible_host=host.domain.com ansible_ssh_port=2226 app3 ansible_host=host.domain.com ansible_ssh_port=2227

-
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
