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```.
