I have a Jenkins server that is running within a Docker container. I custom build the Jenkins image with Docker, Docker Compose and Terraform installed on it.

I run it locally on my Mac, here’s the Dockerfile that configures the Jenkins server:

FROM jenkins/jenkins:latest

USER root

# Install dependencies
RUN apt-get update && 
    apt-get install -y --no-install-recommends 
        apt-transport-https 
        ca-certificates 
        curl 
        gnupg 
        lsb-release 
        software-properties-common 
        awscli 
        python3 
        python3-pip 
        python3-venv

# Install Docker using Docker convenience script
RUN curl -fsSL https://get.docker.com -o get-docker.sh && 
    sh get-docker.sh

# Add Jenkins user to Docker group
RUN usermod -aG docker jenkins

# Install Docker Compose
ENV DOCKER_COMPOSE_VERSION=1.29.0
RUN curl -L "https://github.com/docker/compose/releases/download/${DOCKER_COMPOSE_VERSION}/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose && 
    chmod +x /usr/local/bin/docker-compose

# Install Terraform
ENV TERRAFORM_VERSION=1.8.1
ENV ARCHITECTURE=arm
RUN curl -fsSL https://releases.hashicorp.com/terraform/${TERRAFORM_VERSION}/terraform_${TERRAFORM_VERSION}_linux_${ARCHITECTURE}.zip -o terraform.zip && 
    unzip terraform.zip -d /usr/local/bin && 
    rm terraform.zip

# Create and activate a virtual environment
RUN python3 -m venv /opt/venv
ENV PATH="/opt/venv/bin:$PATH"

# Install required Python libraries
RUN pip install --no-cache-dir requests boto3

USER root

When I run a Jenkins pipeline that eventually reaches a Terraform stage, I get this error:

+ terraform init
/var/jenkins_home/workspace/resume-app-pipeline/resume-app-iac@tmp/durable-fe149f76/script.sh.copy: 1: terraform: Exec format error

When I enter the Docker container that is running the Jenkins server and manually try to input a Terraform command, I get this error:

root@9ac5b490404d:/# terraform --version
bash: /usr/local/bin/terraform: cannot execute binary file: Exec format error
root@9ac5b490404d:/# 

This started to happen yesterday after I upgraded to 1.8.1 from 1.7.5.

I have tried to chmod +x /usr/local/bin/terraform, no luck. Really not sure what is causing this.
