ESCAPE docker-hub / registry

Collection of ESCAPE docker containers as proof of concept without waiting for a EOSC hub Docker-hub? Gitlab registry?

who should provide the containers / images ?

software provider
- need to link ossr records to their containers to find them
- through metadata?
- how?
- having a list of containers is more complicated (many sources)
OSSR
- we can build ossr records that have docker recipes using gitlab in2p3 resources
- Issues:
  - lot of resources?
  - build trigger?
  - nightly? need to find a way not to rebuild every night software that has not changed. We can compare the container metadata version and the record one

centralized git repository vs OSSR

	Advantages	Drawbacks
git repository	pull requests to add env continuous integration to build and test the recipe	gitlab in2p3: accounts and access not all OSSR advantages
OSSR	versioned, archived, citable, discoverable same metadata schema as other OSSR entries many sources (can be managed on whatever platform, be part of several communities...)	curation process? only one curator at the moment no merge request process with direct feedback, trial and error to reach accepted recipe

Can we get the best of both worlds?

central git repo --> archived in OSSR = NOT a good solution
- a recipe should be a single identifiable record
GitHub actions? How to use the CI to get from a centralized repository to single OSSR records?
- the CI publication could take care of making a single record per directory, handle versions, etc... a lot of work and headaches?
