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...

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
