Traefik as a proxy for Docker container with host machines network -


i set following scenario:

  • one physical machine docker containers
  • traefik in container network backend
  • another container using host machines network (network_mode: host)

traefik finds container , adds ip address 127.0.0.1 not accessible traefik container (different network/bridge).

docker-compose.yml:

version: '3' services:     traefik:         image: traefik         ports:             - "80:80"             - "443:443"         volumes:             - /var/run/docker.sock:/var/run/docker.sock             - ./traefik.toml:/etc/traefik/traefik.toml         networks:             - backend      app:          image: my_app          labels:              - "traefik.enable=true"              - "traefik.frontend.rule=host:myapp.example"              - "traefik.port=8080"          network_mode: host networks:     backend:         driver: bridge

the app container added 

server      url                     weight  server-app  http://127.0.0.1:8080   0 load balancer: wrr

of course can access app http://127.0.0.1:8080 on host machine or http://$host_ip:8080 traefik container.

can somehow convince traefik use ip container?

thanks!

without common docker network, traefik won't able route container. since you're using host networking, there's little need traefik proxy container, access directly. or if need access through proxy, place on backend network. if need ports published on host , others proxied through traefik, place on backend network , publish ports need publish, rather using host network directly.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
