I’m trying to build a Docker image of Jenkins with a pre-defined list of plugins. However, I’m encountering an error during the build process.

Here’s my Dockerfile:

# Use the official Jenkins image as the base
FROM jenkins/jenkins:lts

# Install plugins using the plugin installation tool
COPY plugins.txt /usr/share/jenkins/ref/plugins.txt
RUN jenkins-plugin-cli --plugins -f /usr/share/jenkins/ref/plugins.txt 

When I run docker build, I get the following error:

=> ERROR [ 3/21] RUN jenkins-plugin-cli --plugins -f /usr/share/jenkins/ref/plugins.txt                         0.3s

  8 |   
--------------------
ERROR: failed to solve: process "/bin/sh -c jenkins-plugin-cli --plugins -f /usr/share/jenkins/ref/plugins.txt" did not complete successfully: exit code: 127

It seems that jenkins-plugin-cli is not found within the Docker image. Any ideas on how to resolve this issue?
