In the development debugging process, you need to constantly update the code to the Git library, and then use the latest code in the GIT library to update the running Docker container, there are now two ways, it is recommended to use the second.
1. Execute the git command directly in the container and update the directories and files in the container (not recomme
Tags: partition problem lap its info Ldo pex ber everFor developers and DBAs, the impact of the Shell Script batch task is one of the biggest changes in multi-homed options. Because multihomed environments connect to pluggable databases through services, relying on cron and OS authentication becomes one of the biggest problems after switching to a multihomed environment. This article provides some ways to address the problem of a multi-homed environment before Shell scripting works.1. Setting up
Java concurrent programming (4) Synchronous container classSynchronous container class
The synchronization container classes in Java include Vector and Hashtable, which are part of the early-rising JDK. In addition, they also include some similar functions added in JDK1.2. These synchronous encapsulation classes are collected by Collections. synchronizedXxx and o
IntroductionIn some cases, it is necessary for our service to run to generate some logs, or we need to back up the data in the container, or even share data between multiple containers, which inevitably involves the data management operations of the container.There are two main ways in which you manage data in a container:
Data volumes

[Prism] Composite Application Guidance for WPF (5) -- Dependency injection container
Zhou yinhui
The basic services of dependency injection containers and Prism have been mentioned many times in this series of articles. Today, we will separate them and talk about them in detail.
1. Why use the dependency injection container?
We know that in Composite Application, modules are loosely coupled, t
Looking at the history of Docker, you'll find that Docker has been emphasizing the word "application", and Docker wants to provide containerized solutions for distributed applications.From the life cycle of the Docker application software, the development work appears to be before the Docker build, and then containerized testing, deployment, and operations are all tied to the Docker container. It must be said that Docker thinking of the application so
I. Introduction to ContainersIn the Tomcat container hierarchy, the context container directly manages the wrapper class wrapper of the servlet in the container, so how the context container runs will directly affect the way the servlet works.The Tomcat container model is as
IOC dependency reversal: is the dependency between objects that were originally managed by the application and is now given to container management. The good benefit of the transfer of control is to reduce the degree of dependence between the business objects~ How to manage ObjectsThis requires a configuration file, Spring IOC by configuring the configuration elements in the read configuration file, the assembly is instantiated through the individual
Associative container
Associative containers support the use of keys to efficiently find and read elements. The two basic associative container types are map and set. The elements of a map are organized as key-value pairs: The key is used as the index of the element in the map, while the value represents the data that is stored and read. The set contains only one key and effectively supports queries about
Recently, some people in the industry are exploring a trend-"virtual machines: Always glorious or struggling ?" This discussion mainly stems from the discussion of docker and Linux containers. Many people wonder whether container technology will eventually replace virtual machine technology. You may have heard about the Linux container technology, but not everyone has spent time studying the ins and outs of
Ordered container:Vector: supports fast random access;List: supports fast insert/delete, similar to linked listDeque: Refreshing queue.Use the default constructor to achieve the best runtime performance and make containers easier to use.
Initialize a container as a copy of another container:Vector Vecror The container type and element type must be the same.

Vector variable size array. Support for fast random access. Inserting or deleting elements in a position other than the tail may be slow.
Deque a two-terminal queue. Support for fast random access.
The C + + built-in array supports the container's mechanism, but it does not support the semantics of container abstraction. To solve this problem we implement such a class ourselves. in standard C + +, it is implemented with container vectors (vector). A container vector is also a class template.The standard library vector type uses the required header files: #i
C ++ STL vector container learning, stlvector
STL (Standard Template Library) is the most important component of C ++. It provides a set of templates that represent containers, iterators, function objects, and algorithms. The container is the structure of data with the same storage type (such as vector, list, deque, set, map, etc.), and the algorithm completes specific tasks. The iterator is used to travers
