This article focuses on how to run an ASP. NET core application in a Docker container, and then publish the update after modifying the system. This article uses a custom Docker fileSystem Requirements :1. Docker is installed on the server or locallyFirst, create an ASP.

Docker there's a dockerfile, why should we use him?To put it simply: we used to Docker run to create a Docker container that sometimes comes with a lot of parameters.Like what: The code is as follows Copy Code Docker run-d-P 22-p 8080:8080 Ruifengyun/ubunt-redis "Redis-server redis.conf /us

Docker ~ Docker-compose and dockercompose Back to directory Docker-compose is a tool used to define and run complex applications in Docker. For example, to define multiple containers in a yum file, you can use only one line of command to make everything ready and run. Use dockerComposeWe can solve many practical proble

In front of our experimental environment there is only one Docker host, and all the containers are running on this host. However, in a real environment there will be multiple hosts, where containers are started, run, stopped, and destroyed, and related containers communicate with each other over the network, regardless of whether they are located in the same host.How do we manage this multi-host environment effectively?The first problem we faced was i

Before we did the experiment is on a host, in fact, in the real environment there are multiple hosts, containers on these hosts to start, run, stop and destroy, related containers will communicate with each other over the network, whether they are running on the same host.For this kind of song Multi-host environment, how should we manage it efficiently?The first problem is: Install and configure Docker for all hostsPreviously, we installed a

In the traditional model, the development team completes the software development in the development environment, does the unit test itself, passes the test, ᨀ to the Code version Management library. Operation of the application deployment to the test environment, QA testing, no problem, notify the deployment of the release to the production environment. The above process involves at least three environments: development, testing, and production. The reality is that the development of self-test

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
