reset - Docker Chains will be resetted by iptables -


actually have issues docker service. after few min, following rules deleted iptables.

iptables after:

chain input (policy accept) target     prot opt source               destination fail2ban-ssh  tcp  --  anywhere             anywhere             multiport dports ssh  chain forward (policy accept) target     prot opt source               destination  chain output (policy accept) target     prot opt source               destination  chain fail2ban-ssh (1 references) target     prot opt source               destination drop        --  x.x.x.x        anywhere return      --  anywhere             anywhere  chain trafficfilter (0 references) target     prot opt source               destination

iptables before:

chain input (policy accept) target     prot opt source               destination fail2ban-ssh  tcp  --  anywhere             anywhere             multiport dports ssh  chain forward (policy accept) target     prot opt source               destination docker-user   --  anywhere             anywhere docker-isolation   --  anywhere             anywhere accept      --  anywhere             anywhere             ctstate related,established docker      --  anywhere             anywhere accept      --  anywhere             anywhere accept      --  anywhere             anywhere  chain output (policy accept) target     prot opt source               destination  chain docker (1 references) target     prot opt source               destination  chain docker-isolation (1 references) target     prot opt source               destination return      --  anywhere             anywhere  chain docker-user (1 references) target     prot opt source               destination return      --  anywhere             anywhere  chain fail2ban-ssh (1 references) target     prot opt source               destination drop        --  113.100.50.1         anywhere drop        --  200.77.191.71        anywhere return      --  anywhere             anywhere  chain trafficfilter (0 references) target     prot opt source               destination

as can see, there few chains docker-user,isolation , more.. works 1-10 min after that, rules disappear.

did know issue or know how solve this?

okay found it. did service docker restart , after that, save correct iptables persistent rule.v4 file.

it works perfect now!

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
