containers

问题 Basically I have been using a Dictionary object in my program that basically took ints as its keys and stored RTMFP peer IDs in the appropriate locations. Each int was unique and represented one user. Now I'm needing to expand on this where users are identified by a combination of the int and a Boolean value, kind of like this: private var m_iUID:int; private var m_blnIsCurrent:Boolean; Only the combination between those two really uniquely identifies the user. That being said I was just

问题 With new network feature in docker 1.10 it is possible to create isolated overlay networks - which works very well. Containers in 2 separate networks can not talk to each other. Is it possible, however, to deny container in overlay network to reach public internet? Eg to make ping 8.8.8.8 fail, while having docker host connected to internet. 回答1: If you add the --internal flag when creating a network with the docker network create command, then that network will not have outbound network

问题 I am new in docker. I have of applications running on multiple container. Now, I would like to publish all my apps. What I am planning to do is do make a cluster containning all my application. I want at least 4 containers. Nginx container that is facing internet like a reverse proxy. He is responsible to redirect traffic to other containers, since there are not directly accessible through internet. Node_js container that publishes a web in nodejs (http://www.node-app.me). java_EE container

问题 I saw an interview question, which was asked to use "iterator" to read vector<vector<int>> . We have to design the necessary interface? Quite confusing about does this question want to ask? Or how to answer this kind of question. I can imagine that it intends to test C++ STL implementation and objected-oriented design. 回答1: Matrix is in 3*4 dimension. If needed to access only through iterators, this should give you an idea - vector< vector<int> > Matrix(3, vector<int>(3,4)); for( vector

问题 I have a set of controls which I am stacking vertically inside a scrollable control. Each control contains text (like message bubbles on an iPhone), which the bubble resizes based on the height of the text. The problem I face, is when I resize the parent so it is smaller, the bubbles start to overlap, and when I resize so the bubbles are one-line, there is too much space in between each bubble. What I would like to do, is to have each bubble snap the top of the bubble to 10pts off the bubble

问题 So, I'm running a docker container that's getting killed. Memory cgroup out of memory: Kill process 1014588 (my-process) score 1974 or sacrifice child The pid doesn't really help since the instance will be restarted. I'm not sure what to make of the score 1974 portion. Is that some kind of rating? Is that the number of bytes it needs to drop to? Could the kill be issued because of other things on the system that are squeezing this container, or can this only this container is topped out? And

问题 I have a type called Neighbors : typedef vector<pair<data,int>> Neighbors; and here's data : struct data { int par[PARAMETERS]; int cluster; bool visited; bool noise; }; I'm trying to write a function that inserts values from _NeighborPts to NeighborPts (but only ones that aren't already in NeighborPts ): void insert_unique(Neighbors* NeighborPts, const Neighbors& _NeighborPts) { Neighbors_const_it _it = _NeighborPts.begin(); while(_it != _NeighborPts.end()) { if(/* _it->first.par isn't in

问题 I've set up a namespace for my container registry. I tried creating my first docker container. However, now I would like to change the namespace. How can I do this? 回答1: You can't do it. According to IBM Containers Docs The first time that you create a container within an organization, you are prompted to enter a name for the namespace that is associated with the private Bluemix repository. The namespace is used to generate a unique URL that you use to access your private Bluemix repository.

问题 I have recently been going through the book "Scala by Example" in which the author creates an abstract class to represent a set of ints "IntSet" with two subclasses (EmptySet and NonEmptySet) as follows: abstract class Stack[A] { def push(x: A): Stack[A] = new NonEmptyStack[A](x, this) def isEmpty: Boolean def top: A def pop: Stack[A] } class EmptyStack[A] extends Stack[A] { def isEmpty = true def top = error("EmptyStack.top") def pop = error("EmptyStack.pop") } class NonEmptyStack[A](elem: A

问题 According to Boost's documentation, there are two main container types for vertices and their corresponding outgoing edges, with the defaults being vectors for both. Is there any linking between the two going on, as with a map, with the key being the vertex and the value being a vector of outgoing edges? Or do you know what each vertex points to due to the fact that vertices are stored as a unique int in a vertex list, where each vertex would be like an index into some kind of vector of
