Copy folder with wildcard from docker container to host

余生长醉 提交于 2019-12-05 01:25:34
Creating a backup script to dump mongodb inside a container, I need to copy the folder outside the container, Docker cp doesn't seem to work with wildcards : docker cp mongodb:mongo_dump_* . The following is thrown in the terminal : Error response from daemon: lstat /var/lib/docker/aufs/mnt/SomeHash/mongo_dump_*: no such file or directory Is there any workaround to use wildcards with cp command ? You can create the mongo dump files into a folder inside the container and then copy the folder: this is a workaround. It seems there is no way yet to use wildcards with the docker cp command https:/

Finding any element with specific first coordinate in set<pair> >

纵然是瞬间 提交于 2019-12-05 00:58:18
I'm trying to figure out the following problem. Suppose I have the following container in C++: std::set<std::pair<int, int> > my_container; This set (dictionary) is sorted with respect to the order < on std::pair<int, int> , which is the lexicographic order. My task is to find any element in my_container that has the first coordinate equal to, say x , and return the iterator to it. Obviously, I don't want to use find_if , because I need to solve this in logarithmic time. I would appreciate any advice on how this can be done You can use lower_bound for this: auto it = my_container.lower_bound

Get number of elements greater than a number

断了今生、忘了曾经 提交于 2019-12-04 23:53:28
I am trying to solve the following problem: Numbers are being inserted into a container. Each time a number is inserted I need to know how many elements are in the container that are greater than or equal to the current number being inserted. I believe both operations can be done in logarithmic complexity. My question: Are there standard containers in a C++ library that can solve the problem? I know that std::multiset can insert elements in logarithmic time, but how can you query it? Or should I implement a data structure (e.x. a binary search tree) to solve it? ondrejdee Great question. I do

Is there a way to restrict untrusted container scheduler?

☆樱花仙子☆ 提交于 2019-12-04 22:49:27
I have an application which I'd like to give the privilege to launch short-lived tasks and schedule these as docker containers. I was thinking of doing this simply via docker run . As I want to make the attack surface as small as possible, I treat the application as untrusted. As such it can potentially run arbitrary docker run commands (if the codebase contained bug or the container was compromised, input was improperly escaped somewhere etc.) against a predefined docker API endpoint. This is why I'd like to restrict that application (effectively a scheduler) in some ways: prevent -

Call both of After and Before Method in UIPageViewController when swim for forward in Swift 3 iOS

我的未来我决定 提交于 2019-12-04 22:04:08
I made UIPageViewController with datasource array and it's works correctly. But when swiping to right for forwarding call both of After and Before methods. My codes is here: import UIKit class MainPageViewController: UIPageViewController,UIPageViewControllerDataSource { override func viewDidLoad() { super.viewDidLoad() self.dataSource = self initUPageVC(idx:0,isAnimate:false,direction: UIPageViewControllerNavigationDirection.forward) } func pageViewController(_ pageViewController: UIPageViewController, viewControllerBefore viewController: UIViewController) -> UIViewController? { //PRIVIOUS let

docker container port accessed from another container

萝らか妹 提交于 2019-12-04 20:52:05
I have a container1 running a service1 on port1 also I have a container2 running a service2 on port2 How can I access service2:port2 from service1:port1? I mention that the container are linked together. I ask if there is a way to do it without accessing the docker0 IP (where the port is visible) thanks The preferred solution is to place both containers on the same network, use the build-in dns discovery to reach the other node by name, and you'll be able to access them by the container port, not the host published port. By CLI, that looks like: docker network create testnet docker run -d -

Difference between framework and container?

北战南征 提交于 2019-12-04 19:57:37
I was reading this question on SO: Framework vs. Toolkit vs. Library where is explained difference between framework and library. General opinion is that main difference is in Inversion of Control, so you have hot spots in framework where you attach your application functionality (in essence you choose between inheritance/template/heavyweight or composition/strategy/lightweight to achieve that). Ok, now I am curious what is difference between framework and container then? I saw following definition of container (by Rod Johnson): "Container is framework in which application code/objects runs".

import mysql data to kubernetes pod

╄→гoц情女王★ 提交于 2019-12-04 19:08:48
Does anyone know how to import the data inside my dump.sql file to a kubernetes pod either; Directly,same way as you dealing with docker containers: docker exec -i container_name mysql -uroot --password=secret database < Dump.sql Or using the data stored in an existing docker container volume and pass it to the pod . Just if other people are searching for this : kubectl -n namespace exec -i my_sql_pod_name -- mysql -u user -ppassword < my_local_dump.sql To answer your specific question: You can kubectl exec into your container in order to run commands inside it. You may need to first ensure

One DAO per 'container' class or one DAO per table?

前提是你 提交于 2019-12-04 18:51:43
问题 I have a 'container' class with fields that are contained in several database tables, and I use the DAO pattern for accessing the data. The question is, should I create a single DAO for this 'container' class, or is it better to have one DAO per table and combine their data? 回答1: You should design your DAO according to your application needs, not the layout of your database. Start of with one DAO, and if it becomes too large, then refactor it into multiple DAOs in a way that makes sense to

EaselJS: connect 2 containers/shapes using a line

自作多情 提交于 2019-12-04 18:17:44
I want to be able to click on a container/shape and as I move the mouse a line that can be connected to another container/shape (with an arrow at one end) is drawn. Ideally I want this line to snap to the destination element. I'm new to EaselJS and I've got no clue on how to go about this. This is the closes I've come across of here, and I can't make sense out of it: Drawing a Line in a html5 canvas using EaselJS Here is a quick demo I put together The key steps are: Listen for mousedown on the initial item Create a shape to draw the connection when the mouse is pressed Listen for mousemove
