containers

问题 I'm looking for some STL, boost, or similar container to use the same way indexes are used in databases to search for record using a query like this: select * from table1 where field1 starting with 'X'; or select * from table1 where field1 like 'X%'; I thought about using std::map, but I cannot because I need to search for fields that "start with" some text, and not those that are "equal to". Beside that, I need it to work on multiple fields (each "record" has 6 fields, for example), so I

问题 Are we supposed to be able to inherit from Qt containers such as QList , QVector or QMap in order to specialize them and add functionality? If so, what do we need to do in order to be sure that the container works correctly (virtual methods, virtual destructor etc..?). If not, why not and what other options do I have? 回答1: Both, STL and Qt Containers opt for non virtual destructors. There is an interesting discussion why this is, and why its not fixed with Qt5. QList has no virtual destructor

问题 Why would you connect two docker containers via network namespace, and not just through one network? As far as I know the only difference is that you can call the other container using localhost. I don't see any use case where this would be necessary. Does anyone have experience with this? 回答1: One reason I can think of is for using a tool or command that is not available in your container. This example below comes directly from the docker run docs: NETWORK: CONTAINER Example running a Redis

问题 I have a configmap where I have defined the following key-value mapping in the data section: apiVersion: v1 kind: ConfigMap metadata: namespace: test name: test-config data: TEST: "CONFIGMAP_VALUE" then in the definition of my container (in the deployment / statefulset manifest) I have the following: env: - name: TEST value: "ANOTHER_VALUE" envFrom: - configMapRef: name: test-config When doing this I was expecting that the value from the configmap (TEST="CONFIGMAP_VALUE") will override the

问题 Related: Deprecation of std::allocator<void>. The following description about template parameter Allocator is found for both std::vector and std::list (emphasis mine): An allocator that is used to acquire/release memory and to construct/destroy the elements in that memory. The type must meet the requirements of Allocator. The behavior is undefined if Allocator::value_type is not the same as T . The last sentence does not make sense to me. If a specific value_type is required, couldn't it just

问题 I am running a windows docker container on a Windows Server 2016 host, running default configuration. When running the docker container using the command: docker run -it microsoft/windowsservercore powershell When I run the command: ping <hostIPAddress> It just says that the request times out. I have checked that I can ping 8.8.8.8 and google.com etc... and even other machines on the same subnet. The only one I cannot ping is the host. I have added '--dns ' to the 'docker run' command but

问题 I am having a difficult time grasping how to iterate an octree or quad. And it may be because I am not experienced with different mythologies of iterating. But let’s suppose that I produced a quad tree that holds float x,y,z; dword color. Now, Let’s also say that this node can only produce 4 children at a time (and those children can both produced 4 children, etc, etc) up until: 7 levels are reached (so that child can’t create anymore children, but its brothers/sisters can), all 4 children

问题 I tried to install postgresql-9.3 in the container contains images "ubuntu: 14:04" The first step, which I did make images "ubuntu: 14:04" $ sudo Docker pull ubuntu:14.04 The second step, I create a container with the command $ sudo docker run -t -i ubuntu:14.04 /bin/bash The third step, I install postgresql-9.3 in a container contain "ubuntu:14.04" (in a container containing ubuntu) I tried to get in postgresql could, then I tried to get out containers, straight out with the command # exit I

问题 I'm confused about docker swarm. As far as I know, the old way to run a swarm was to run manager and workers in containers, before docker engine provided native support for swarm mode. Documentation for the old, containerized swarm explained how to setup service discovery using consul, etcd or zookeeper. Service discovery is necessary, as services are ran at random ports to avoid collisions, right? Documentation for the docker engine swarm mode doesn't explain how to setup service discovery.
