Builders¶

Common features among builders¶

All of the builders share some common features.

Configuration file structure¶

When working with science-build-environment, all configuration files should be stored in the following file structure:

<build rules repo>/configs/<build target>/<builder>/*.yaml

e.g.:

~/science-build-rules/configs/centos/spack/packages.yaml

All configuration files should be in yaml-format.

build_config.yaml and deployment_config.yaml¶

All builders have these configuration files. build_config.yaml contains the configuration for the builders and its format depends on the builder. deployment_config.yaml contains configuration for the deployers. Its format is described in the Deployers-page.

Spack-builder¶

Spack-builder uses Spack for installing software. Before running the builder spack should be available in the shell that launches the build.

After validating the configuration structure, the build runs the following build rules:

Reindex installed packages
Remove old compilers configuration file
Add existing compilers
Install compilers
Install packages
Recreate modules
