Resolving Permission Denied Error with dagster_cloud_pre_install.sh in Serverless Deployments

Last updated: October 24, 2025

  • When executing a serverless deployment with a dagster_cloud_pre_install.sh script, you may encounter a permission denied error that looks like this:

    /bin/sh: 1: ./dagster_cloud_pre_install.sh: Permission denied

  • This error typically occurs due to incorrect file permissions in your Git repository. To resolve this:

    1. Ensure the script has executable permissions by running: 

      git update-index --chmod=+x dagster_cloud_pre_install.sh

    2. Commit the permission changes to your repository

    3. Push the changes and retry your deployment

  • The issue occurs during the Docker build process when trying to execute the pre-install script that typically contains system-level package installations. Here's an example of a valid pre-install script:

    set -euo pipefail
export DEBIAN_FRONTEND=noninteractive

# Base deps
apt-get update
apt-get install -y --no-install-recommends curl gnupg ca-certificates lsb-release

# Additional package installations
...
