Run the asp.net core cross-platform application in Docker, dockerasp.net Overview Docker has been hot for a year or two, and I believe this is not a flash of technology, it is an innovation that will profoundly influence our future development, deployment, and operation of application systems (many people regard it as a very important cornerstone of devops ).

Docker and docker tutorials Configuration of installing Docker and Fig and their environment in ubuntu 1. Docker Installation Install Docker using the apt-get command: $sudo apt-get install docker.io Start the service and daemon $sudo service docker.io status $sudo service

Docker service is a declarative, scalable, load-balanced application. Docker service is a user-oriented application, while Docker swarm is an IT-oriented node cluster. Docker service is often run on the basis of Docker swarm. Common commands for

1. What is a container?Virtualization technology based on Linux kernel functions2. What is Docker?An open Source engine that automatically deploys applications to containers3. What is the difference between Docker and existing tools? The traditional deployment mode is: Installation (Package management tool or source package compilation), configuration---run; The deployment mode for

1 First you have to prepare a hub account, go to https://hub.docker.com register it!2 Create a new warehouse at the hub, which is similar to the one on GitHub. Creation---> Create repository (Creating a knowledge Base) and then just a name, I'll call it Ubuntu, so the path is Wherein/ubuntu.3 Run Docker PS View container, here is to get to container ID4 Commit a container command: Docker commit CONTAINER ID

Restart the server, previously able to run the Docker network applications can not be opened normally. Because of the use of CENTOS7, so speculation is likely to be a iptables problem. Docker start or run always prompt for a similar error:No Chain/target/match by that name Google a bit, and some people actually encountered similar problems.Centos 7 of/etc/sysconfig/iptables files: *nat :P rerouting ACCEPT [

This article is from the "Knowledge Forest" In the previous example, the communication between the container and the container is done through the IP address in the network, which is obviously unreasonable, because the IP address may change when the container is started, and it is also more difficult to remember. The solution to this problem is to use a network alias, the container is allowed to be alias on the network, and the alias can be directly accessed in the network, which is similar to t

Docker intranet: Docker-registry with Nginx SSL on CentOSSince Docker-registry is also a software application, the easiest way to do this is to use the officially provided image registry that has been deployed. The official documentation also gives suggestions for running sudo docker run -p 5000:5000 registry commands

If it's just that you're not satisfied please don't look down!For a specific version of the issue, the search through the official website document and issue on GitHub, there is always no good answer, and the product developers do not know why not always provide a positive approach, perhaps to promote the new version,But is this really good?
