How to run ASP.NET Core 2.1 in Docker
Today, I will talk to you about how to run ASP.NET Core 2.1in Docker. Many people may not know much about it. In order to make you understand better, the editor has summarized the following content for you. I hope you can get something according to this article.
1. Create a new ASP.NET Core 2.1project
Then run the project to make sure that the project we just set up works properly.
two。 Write Dockerfile
Create a new text file named Dockerfile
FROM microsoft/dotnet:2.1-aspnetcore-runtimeWORKDIR / appCOPY. .EXPOSE 80ENTRYPOINT ["dotnet", "AspNetCore.Docker.dll"]
Here we need to use the official image: microsoft/dotnet:2.1-aspnetcore-runtime
If you want to try a smaller image, you can try microsoft/dotnet:2.1-aspnetcore-runtime-alpine. This image uses alpine, a stripped-down version of linux, but some features are castrated, which need to be tested in actual use, such as internationalization support. It is not enabled in this image by default, and you need to configure environment variables to enable it.
You need to set the following properties of Dockerfile to ensure that it can be copied to the release directory:
3. Build a Docker image
We name the image: aspnetcoredocker
Go to the release file directory and execute the command to package the image:
Docker build-t aspnetcoredocker.
We can write release + build scripts.
Windows:
File name: build.bat
@ echo offecho "Windows Docker build" cd.. / AspNetCore.Dockerdotnet publish-c Release-o.. / publishcd.. / publishecho "publish success" docker build-t aspnetcoredocker.
File name: Linux:
Build.sh
#! / bin/bashecho Linux Docker buildcd.. / AspNetCore.Dockerdotnet publish-c Release-o.. / publishcd.. / publishecho publish successdocker build-t aspnetcoredocker.
The folder structure is shown below:
Perform the build:
. / build.sh
After the construction is successful, you can query the image we built through the docker images command:
If you encounter the error "- bash:. / build.sh: / bin/ bash ^ M: bad interpreter: No such file or directory" when executing the sh script under linux, edit the sh script through vim/vi, press: Jian, enter set ff=unix, then enter and save it with wq.
4. Run Mirror
Run through the command
Docker run-- name=aspnetcoredocker-p 777777 aspnetcoredocker 80-d
-- name: specify the container name
-p: specify the container port
-d: specify the container to run in the background
If a long string appears, it indicates that the operation is successful:
We can also query the container we are running with the docker ps command:
We can also view the startup log through docker logs:
5. Authentication acc
We can access the asp.net core website launched by our container directly through the curl command:
Or access it directly through the browser:
