Build failed: docker pull

Hello,

I started the tutorial and now I am at the first run of the pipeline.
When arrived at the "docker pull" command Jenkins throws the following error:

+ docker pull python:2-alpine
/var/jenkins_home/workspace/simple-python-pyinstaller-app@tmp/durable-358c4a38/script.sh: 1: /var/jenkins_home/workspace/simple-python-pyinstaller-app@tmp/durable-358c4a38/script.sh: docker: not found
script returned exit code 127

I am using Jenkins via Docker image on the Windows Docker Desktop application (WSL2). I attached the Jenkins log file.
