build action New!

The build action allows you to build an Exegol image locally from source. This is useful when you want to customize the image or when you need to build for a specific architecture.

When building an image, you can either:

• Use the default Exegol build profiles
• Use custom Dockerfiles

Build Reliability

Building Exegol images locally can be challenging. It's a long process, and may fail due to:

• Regular updates and changes in the tools and dependencies
• Incompatibilities between different versions of tools
• Network issues during the build process
• System-specific requirements and configurations

We strongly recommend using pre-built images (exegol install) unless you have a specific need to build locally.

Build Process

1. Choose a name for your image (if not specified in command)
2. Choose a profile (if not specified in command)
3. The build process will start

Options

Option	Description
IMAGE	Tag used to target an Exegol image
BUILD_PROFILE	Select the build profile used to create a local image
--build-log LOGFILE_PATH	Write image building logs to a file
--build-path DOCKERFILES_PATH	Path to the dockerfiles and sources

Command examples

# Build interactively an exegol image
exegol build

# Build interactively a local image named myimage
exegol build myimage

# Build the myimage image based on the full profile and log the operation
exegol build myimage full --build-log /tmp/build.log

Cross-architecture builds

While the --arch parameter is supported, cross-architecture builds are not recommended because:

• They may require additional setup (QEMU, Docker buildx)
• They are significantly slower due to emulation
• Some tools may have architecture-specific dependencies

If you need to build for a different architecture, consider using a native system of that architecture instead.
