Avoiding Build Failures with Adobe ColdFusion Docker Images: Specifying Module Versions

Here's the revised text with your example included:

---

If you are using a Docker image of Adobe ColdFusion, such as `adobecoldfusion/coldfusion2021:2021.0.13`, and in the compose file you have set the environment variable `INSTALL_MODULES=ALL`, the Docker container will fail to build.

The issue is related to the latest hotfix update 14, which was released recently. When you specify `INSTALL_MODULES=ALL`, it attempts to install all ColdFusion packages to their latest version if you do not specify any version for the packages. This works fine if you are using the latest build tag of ColdFusion.

On June 12, 2024, ColdFusion 2021 update 14 was released. I was still using the ColdFusion base Docker image `2021.0.13`, where the latest update 14 is not installed. When the container starts and `INSTALL_MODULES=ALL` is set, it tries to install the packages to their latest version. Some packages require the latest update (e.g., update 14) to install the latest version of those packages, causing the build to fail.

**Solution:** Specify the version for the modules to be installed to avoid this issue. For example, use `INSTALL_MODULES=pdf:2021086,document:2021087,...`. If you use the latest tag, it won't cause this issue, but that is not the recommended way to use the Docker image in production environments.
