(This article also published in my public number "dotnet daily Essence article", Welcome to the right QR code to pay attention to. ) Translator : In fact, I have been studying this part of the past week, the results of the weekend did not have time to summarize the article, Scott Hanselman. Then I will translate this article, let more Chinese readers see. Of course, I met Scott's pit. But first, I'll explain the concepts of Linux containers and Windows containers for unfamiliar friends. As conta
The current program is Gitlab + Jenkins + Docker + Kubernetes.The workflow for the scenario is as follows: First, the developer submits the code code, and then the GITLAB automatically triggers the Jenkins job,jenkins job to build the corresponding image, placed in a kubernetes pod; The Kubernetes pod will include othe

Dockerfileis the raw material of the software, Docker镜像 is the delivery of the software, but it Docker容器 can be considered as the operating state of the software. From the perspective of application software, Dockerfile, Docker images and Docker containers represent three different stages of the software, Dockerfile de

Docker mirroring
Docker mirroring (image) is similar to a virtual machine image, and can be interpreted as a read-only template for the Docker engine, including a file system.
For example, a mirror can fully contain the Ubuntu op

First of all, it is clear that this article describes how to deploy the dotnetcore project in the production and testing environments. In the past, in the frameworks project, we can set the web. environment Variables of config, and then specify specific variables when releasing to release the produc

Before Docker 1.9 was born, there were roughly three container communication scenarios across multiple hosts, such as:
1. Port mapping
The port P of host A is mapped to Port P ', which is the network space listener of container C, and is only available for applications and services
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

The research on the container network has been interrupted for some time due to the reasons for the exchange of work in 2016. With the current project to kubernetes application in depth, I feel that before the shallow understanding of the container network is not enough, the container
Server virtualization refers to the operating system and hardware to add a layer, called the hypervisor layer, the next control hardware, on the host operating system, operating system OS in file form, known as virtual machine, the main problem is the hardware utilization and flexibility of the problem, the common solution for VMware Vsphere,xen,kvm,hyper-v.. Container virtualization refers to the application of packaging in the OS to run in the form
The container is the second core concept of Docker, and the simple one is that the container is a running instance of the mirror, and the difference is that it has an extra writable file layer. If the virtual machine is simulated running a full set of operating systems (providing a running state environment and other system environments) and running on the appli
Objective
Today, in the Docker, we are able to easily package our applications with containers and deploy them on our servers and run them. However, talking about how to stop the Docker container in the running and terminate the program correctly is a very worthwhile topic to discuss.
In fact, in our daily projects, this is a problem that we often have to confr

In this article, we will discuss five (4
The last section mentions that when the container is running, the data generated will not be in the write image, and re-starting the new container with this image will initialize the image and add a new read-write layer to hold the data. If you want to do data persistence, Docker provides data volume or data container
