As a new generation of virtualization, Docker will certainly be widely used in the future. The deployment of traditional virtual machines needs a lot of operation and maintenance manpower to ensure the consistency of development environment, test environment, UAT environment and production environment. With Docker, we can deploy once and run everywhere.

This article describes how to deploy an ASP.NET Core Web site to run in Docker.

Software environment list

CentOS 7.3.1611Docker 1.12.6.NET Core 1.1

Install Docker

$# install Docker$ yum install docker$ # start docker service $systemctl start docker.service$ # configure boot $systemctl enable docker.service

Configure Docker Accelerator

For well-known reasons, if you want to use Docker smoothly, you need to configure Docker accelerator, otherwise you will feel like you are back to the era of dial-up Internet access.

I use DaoCloud, which is claimed to be forever free. The registered address is https://account.daocloud.io/signin.

You can quickly complete registration with a scan with Wechat.

After registration, a configuration script address is provided:

$# configure docker accelerator $curl-sSL https://get.daocloud.io/daotools/set_mirror.sh | sh-s http://xxxxxx.m.daocloud.io$ # restart takes effect $systemctl restart docker

Pull ASP.NET Core image

$docker pull microsoft/aspnetcore$ # check for success $docker images

Prepare the ASP.NET Core website release file

You can refer to my previous article: publishing the ASP.NET Core website to the Linux server

Create Dockerfile

Put it in the root directory of the website. The contents of the file can be referenced as follows:

FROM docker.io/microsoft/aspnetcoreCOPY. / publishWORKDIR / publish EXPOSE 8080CMD ["dotnet", "TestAspNetCoreWeb.dll"]

Package image

$# notice that there is one last point. $docker build-t test-netcore:1.0.

Start the container

$docker run-- name test-netcore-p 8080 test-netcore:1.0 8080-d $# check whether the container is started successfully. If it doesn't work after startup, try docker run without adding-d. If there is an error, there is a message. $docker ps

The website runs successfully.

Attached

During the configuration process, I encountered two cases in which the container failed to start:

1. The monitoring of the website uses ip and reports an error of "Error-99 EADDRNOTAVAIL address not available".

two。 Localhost is used to monitor the website, and the error "curl: (56) Recv failure: Connection reset by peer" is reported.

Finally, it is found that the use of http://*:8080 to monitor is successful.

Running docker run again after a failure indicates that the name already exists. You can use docker rm-f [Container name] to delete the container or change the name.

The above is the whole content of this article, I hope it will be helpful to your study, and I also hope that you will support it.
