Eiffel bundle: Mongo-Seed service is not started when '-s' flag provided

[tobiasake]

Description

When Eiffel bundle is started with few components with "-s" flag then "mongo-seed" service is not started/loaded and no subscriptions becomes available in Eiffel-Intelligence.

Fix so Mongo-seed service is launched also when few Eiffel components configured to start.

This issues is seen in Docker. Check also that this issue don't occur when executed in Kubernetes.

@e-backmark-ericsson @m-linner-ericsson @tobiasake Perhaps that's not a bug, if I understood correctly the issue here. Yet, the valid service name is "mongo_seed" instead of "mongo-seed". I have tested it on Docker and K8S and the installation was correct as it's shown in the attached photo.

I think the issue is that if not the full Eiffel bundle but just parts of it (like RabbitMQ, Jenkins, EI and ER for example) are explicitly requested through -s flags, then the mongodb seeding is not done. So, try to start using e.g. something like './easy2use start Eiffel -s <rabbit> -s <jenkins> -s <ei-frontend> -s <ei-backend-artifacts>-s er' (replace services in <> with real service names)

@tobiasake Would you expect that mongo_seed should be started with the Eiffel Intelligence or was there any other service it should be connected with? Could you provide a example of a working command and one where it doesn't work?

Hi, This is really old stuff and I don't remember all details.

I guess user need to provide mongo-seed manually today when -s flag is provided with a list of services, and if EI is specified without monog-seed then no subscription will be seeded to mongoDb instance. I think the goal with this ticket is about if EI are specified on -s flag, then there should be some kind of dependencies to mongo-seed so mongo-seed is deployed and executed as well, even if mongo-seed are not specified on the -s flag.

I think in docker-compose it exist a dependency field per service that could be used maybe for this and in Kubernetes I think this could be configured as a sidecar job in the helm charts or something similar when EI are deployed. Now I am speculating without knowing the full technically details :)

[m-linner-ericsson]

@tobiasake If I interpret you correct, this ticket is about starting the mongo_seed when EI is started.

[tobiasake]

@m-linner-ericsson Yes, some dependency start of mongo_seed. But sametime maybe there is use-cases where user just want to start Eiffel-Intelligence without subscriptions loaded from mongo_seed. So maybe its better to have it like is today and add some docs about mongo_seed application name need to be specified to -s flag if user want to have the subscription loaded from mongo_seed application/container.

@tobiasake @emichaf @m-linner-ericsson "mongo_seed" service's job does not complete at all even if we deploy Eiffel bundle with all services. The reason is that EIFFEL_MONGODB_VERSION=4.4.1 and the container image bitnami/mongodb that is used, it is always the latest. The raised error is "mongo command not found" which for mongodb>=6.0 the command is mongosh.

The service works pulling bitnami/mongodb:4.4.1.

Regarding mongo_seed dependencies, we could document it as it has been mentioned in other comments.
