java - send tomcat conf files to container using kubernetes -


i new docker , kubernetes, trying create container having tomcat7/java7 deploy webapps it. concern have tomcat/conf config files, have details of database connections, threadpool, java memory etc.

what want copy these files kubernetes server docker-container , place them @ right places, while starting container.

p.s: don't want via enviroment variables, going huge in numbers if keep variable every entry in config files.

you add configmap in kubernetes, tomcat config (files or whole dir)

kubectl -n staging create configmap special-config --from-file={path-to-tomcat-conf}/server.xml

and mount on pod (kubectl create -f path/to/the/pod.yaml)

apiversion: v1 kind: pod metadata:  name: tomcat-test-pod spec:  containers:  - name: test-container    image: tomcat:7.0    command: [ "catalina.sh", "run" ]    volumemounts:    - name: config-volume      mountpath: /usr/local/tomcat/conf/server.xml  volumes:  - name: config-volume    configmap:     # provide name of configmap containing files want     # add container     name: special-config

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 ...
