Examples

Build All Distros For All Builders

This will build all distros for all builders.

python -m packer_builder build -o ~/projects/packer/builds

Build All Distros For A Specific Builder

This will build all distros for a specific builder (virtualbox-iso in this example).

python -m packer_builder build -o ~/projects/packer/builds -b virtualbox-iso

Build A Specific Distro For All Builders

This will build a specific distro (CentOS in this example) for all builders.

python -m packer_builder build -o ~/projects/packer/builds -d CentOS

Build A Specific Distro For A Specific Builder

This will build a specific distro (CentOS in this example) for a specific builder (virtualbox-iso in this example).

python -m packer_builder build -o ~/projects/packer/builds -d CentOS -b virtualbox-iso

Define Default Password At Runtime

Because there might be a scenario in which you would want to override the password for all distros defined in distros.yml. You can pass this override password as part of the CLI arguments.

python -m packer_builder build -o ~/projects/packer/builds -p SuperSecretPass

Generate Templates (ONLY)

python -m packer_builder generate-templates --outputdir ~/projects/packer
