在 jenkins 容器内安装 php 和 composer

Question

I'm trying to create a Jenkins pipeline that has a 'Test' stage which requires PHP and Composer in order to run the tests with PHPUnit.

How do I install PHP (preferably version 7.4) and Composer inside a Jenkins Docker container?

This is how I tried inside the container's Dockerfile:

FROM jenkins/jenkins

USER root

# install PHP and Composer
RUN apt-get install -y php php-mbstring php-xml php-bcmath && \
    apt-get install -y composer
    
USER jenkins

When I build the image I get this error:

Step 3/4 : RUN apt-get install -y php php-mbstring php-xml php-bcmath php-fpm &&     apt-get install -y composer && apt-get install -y vim

You miss apt-get update before install .

The sudo apt-get update command is used to download package information from all configured sources
