Dedal

This repository provides functionalities to easily managed spack environments and helpers for the container image build flow.

Setting up the needed environment variables The <checkout path>\dedal\.env file contains the environment variables required for OCI registry used for caching. Ensure that you edit the <checkout path>\dedal\.env file to match your environment. The following provides an explanation of the various environment variables:

   # OCI Registry Configuration Sample for concretization caches
   # =============================
   # The following variables configure the Harbor docker OCI registry (EBRAINS) used for caching.
   
   # The hostname of the OCI registry. e.g. docker-registry.ebrains.eu
   CONCRETIZE__OCI_HOST="docker-registry.ebrains.eu"
   
   # The project name in the Docker registry.
   CONCRETIZE__OCI_PROJECT="concretize_caches"
   
   # The username used for authentication with the Docker registry.
   CONCRETIZE__OCI_USERNAME="robot$concretize-cache-test+user"
   
   # The password used for authentication with the Docker registry.
   CONCRETIZE__OCI_HOST="###ACCESS_TOKEN###"
    

   # OCI Registry Configuration Sample for binary caches
   # =============================
   # The following variables configure the Harbor docker OCI registry (EBRAINS) used for caching.
   
   # The hostname of the OCI registry. e.g. docker-registry.ebrains.eu
   BUILDCACHE_OCI_HOST="docker-registry.ebrains.eu"
   
   # The project name in the Docker registry.
   BUILDCACHE_OCI_PROJECT="binary-cache-test"
   
   # The username used for authentication with the Docker registry.
   BUILDCACHE_OCI_USERNAME="robot$binary-cache-test+user"
   
   # The password used for authentication with the Docker registry.
   BUILDCACHE_OCI_HOST="###ACCESS_TOKEN###"

For both concretization and binary caches, the cache version can be changed via the attributes cache_version_concretize and cache_version_build. The default values are v1.

Before using this library, the following tool must be installed on Linux distribution:

    apt install -y bzip2 ca-certificates g++ gcc gfortran git gzip lsb-release patch python3 python3-pip tar unzip xz-utils zstd

    python3 -m pip install --upgrade pip setuptools wheel
