Agent Docker not execute any sh command - docker

Question

Computer Mac M1
Create a Docker image from jenkins 2.355 with Docker Pipeline 1.28
When run a simple agent docker like this:
pipeline {
agent { docker { image 'node:16.13.1-alpine' } }
stages {
stage('build') {
steps {
sh 'node --version'
}
}
}
}
The agent is pull correctly but the sh command is never executed. The jod is freezed and after many seconds the job stoped .
This is the console log obtained:

[Pipeline] Start of Pipeline

[Pipeline] {

.
[Pipeline] }
[Pipeline] // withEnv

Jenkins does not seem to be running inside a container

What is wrong??

following the instructions here in https://www.jenkins.io/doc/book/installing/docker/ totally fixed this problem for me. Just remove everything related to your existing Jenkins image, volume etc...and start again from scratch with those instructions.
I guess the new updates have changed the way DinD works with Jenkins.
I hope it works out for you.
