Kubernetes Install issue

[Sharathmk99]

Hi,

I'm trying to install nboost in Kubernetes cluster using below command,
helm install nboost --set replicaCount=3 --set service.type=ClusterIP --set args.uhost=elasticsearch-elasticsearch-coordinating-only nboost/nboost

Its crashing,

Can you please help.

Just ran into this too. you can set config: null multiplier: null rerank: null search_path: null in helm values.yaml
or use --set args.config=null --set args.multiplier=null --set args.rerank=null --set args.search_path=null on the command line for helm install

[jalberto]

in addition to @si-rob lr: null it's also needed but still, there is an issue with the models:

nboost OSError: Model name 'pt-bert-base-uncased-msmarco' was not found in model name list (bert-base-uncased, bert-large-uncased,...)

So the configured probes in helm are causing that MissingQuery exception, disabling the probes is workaround thou.

Now Next error:

@jalberto I have same error, but wtihout Kubernetes set up. What kind of database we are talking about here? Is some config key is missing?

@colethienes Also validated and got same result by using standalone pip package. Anybody have an idea what's wrong with it?

[jalberto]

It's elasticsearch, I still was not able to make this work El lun., 13 abr. 2020 13:51, Konstantin Perikov <[email protected]> escribió:

@jalberto I doubt, error message is saying

sqlite3.OperationalError: unable to open database file

which is have to do with sqlite, not Elastic itself. Also I managed to make it working on 0.3.3 which means, that it's potentially a bug introduced

[kaykanloo]

Most likely the same bug as #61
