How to install telnet in Docker for Windows 10

Question

When I run te.net command in Docker it does not run.

Could you please tell me how to install te.net in Docker for Windows?

Answer 1

我知道一个老问题，但您可以在 dockerfile 中使用以下内容在 docker for windows 上安装 telnet

  RUN powershell -Command Add-WindowsFeature "telnet-client"

Answer 2

有一个 docker 图像：

docker run mikesplain/telnet <host> <port>

Answer 3

If you are trying to telnet into your container to gain access to it, that isn't how you would want to connect. Docker provides that functionality.

Connect into a running container - Docs :

docker exec -it <container name> bash
$ root@665b4a1e17b6:/#

Start a container from image, and connect to it - Docs :

docker run -it <image name> bash
$ root@665b4a1e17b6:/#

Note: If it is an Alpine based image, it may not have Bash installed. In that case using sh instead of bash in your commands should work.

Answer 4

If you were using Kubernetes, you could install telnet in k8s by running:

apk update
apk add busybox-extras
telnet 10.0.180.37 11211

Answer 5

The following command will work if you want to install Te.net client in a running Windows Docker container. Just run this command in your container's terminal:

dism /online /Enable-Feature /FeatureName:TelnetClient
