consul - Health-check of a redis job flagged as critical in Nomad -


when deploying redis job in nomad (0.6), not manage have healthy in consul.

i start consul in container , make port 8500 available on localhost.

 $ docker container run --name consul -d -p 8500:8500 consul

when run nomad, connects correctly consul can see in logs.

 $ nomad agent -dev     no configuration files loaded ==> starting nomad agent... ==> nomad agent configuration:                  client: true              log level: debug                 region: global (dc: dc1)                 server: true                version: 0.6.0  ==> nomad agent started! log data stream in below: ...     2017/08/18 15:45:28.373766 [debug] client.consul: bootstrap contacting following consul dcs: ["dc1"]     2017/08/18 15:45:28.377703 [info] client.consul: discovered following servers: 127.0.0.1:4647     2017/08/18 15:45:28.378851 [info] client: node registration complete     2017/08/18 15:45:28.378895 [debug] client: periodically checking node changes @ duration 5s     2017/08/18 15:45:28.379232 [debug] consul.sync: registered 1 services, 1 checks; deregistered 0 services, 0 checks ...

i run redis job following configuration file

 job "nomad-redis" {   datacenters = ["dc1"]   type = "service"    group "cache" {      task "redis" {       driver = "docker"        config {         image = "redis:3.2"         port_map {           db = 6379         }       }        resources {         cpu    = 500 # 500 mhz         memory = 256 # 256mb         network {           mbits = 10           port "db" {}         }       }        service {         name = "redis"         port = "db"         check {           name     = "alive"           type     = "tcp"           interval = "10s"           timeout  = "2s"         }       }     }   } }

redis service added consul appears critical. seems healthcheck cannot done. understand, checks done within task. there i'm missing ?

running consul on localhost or in container attached host network (--net=host) fixed thing.

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
