containers

问题 I know that questions similar to this one is already asked on SO. But, it doesn't make clarification on what I am looking for. I am trying to get my hands dirty on docker. I have encountered the terminology docker host and docker node . I am referring this article:- https://docs.docker.com/get-started/part3/#docker-composeyml. I know that docker host is the one, which runs one or more containers and in which docker engine is installed. Moreover, docker host can either be a physical machine or

问题 I just created my own Container, its structure looks like this: Container |- TabsContainer |-Button1 |-Button2 |-Button3 ... It should be like this: and be positioned at the bottom of the screen, like this: in every Form I create. When I add this custom Container to the 4 of my Forms, I still want all of the buttons to do the exact same thing. How could I do this? And In what function? before ? I already tried onPostShow() of my login Screen by getting all of them with their unique component

问题 In this example, how can I access a property in object $containerObj from the getContainerID() method in object $containerObj->bar , or at least get a pointer to the $containerObj ? class Foo { public $id = 123; } class Bar { function getContainerID() { ... //**From here how can I can access the property in the container class Foo?** } } $containerObj = new Foo(); $containerObj->bar = new Bar(); echo $containerObj->bar->getContainerID(); 回答1: You cannot do that in this way. A reference to a

问题 I am new to Docker and experimenting by creating an image from an existing Rails/Unicorn/MySQL app. My files are below and the image successfully creates but I'm unclear if things are actually working properly as I can't access the traditional Unicorn localhost URL, or the boot2docker IP. So my question is, how do I access a Unicorn server locally on OSX with a Docker image running? Dockerfile # Dockerfile FROM seapy/rails-nginx-unicorn # Publish port 8080 EXPOSE 8080 CMD ["bundle", "exec",

问题 I am using WebApp for Container in Azure, currently I build my own containers in Jenkins and push it to my own private registry. My Own private registry is very basic and doesn't have functionality for WebHook, so I would like to add in my Jenkins workflow to trigger the container refresh. I have followed these steps: https://docs.microsoft.com/en-us/azure/app-service/containers/app-service-linux-ci-cd and I got the URL but when I try to curl to it I got: 401 - Unauthorized: Access is denied

问题 I'm trying to write a Dockerfile for use as a standardized development environment. Dokerfile: FROM node:9.5.0 WORKDIR /home/project # install some stuff... # clone the repo RUN git clone https://github.com/... . # expose VOLUME /home/project # fetch latest changes from git, install them and fire up a shell. CMD git pull && npm install && /bin/bash After building the image (say with tag dev ), Running docker run -it dev gives me a shell with the project installed and up-to-date. Of course

问题 Is there a way to automatically lock an STL container on access, without having to lock and release around it? 回答1: The currrent C++ standard does not say anything about thread safety for STL containers. Officially it is possible for an STL implementation to be thread safe, but it's very unusual. If your STL implementation is not thread safe, then you will need to "lock and release around it" or find some other way to coordinate access. You may be interested in Intel's Threading Building

问题 As I look at the standard for different STL objects and functions, one thing that doesn't make sense to me is why would the begin() and end() functions for container objects return an iterator by value rather than by constant reference? It seems to me that iterators could be held by the container object internally and adjusted whenever the container is mutated. This would mitigate the cost of creating unnecessary temporaries in for loops like this: for (std::vector<int>::iterator it=my_vec

问题 After reading through most of the maps questions, I eventually got an idea from this link: How to unique my data that are stored in an object which are stored in a vector? I have a task of storing X , Y , Z coordinates from the user input. To prevent the user from entering duplicated data, I have decided to use map containers as they do not allow duplicated data. I tested the code out. I am using X as the key and Y as the value I am able to store X and Y via this: map<int, int> mapp2d; mapp2d
