Hi JB, I think it's a good idea !
I'm agree with adding docker as a dedicated module in Karaf container because it just use docker. It would be also interesting to be able to create an image of Karaf from the running instance :) François Le 18/01/2018 à 13:37, Jean-Baptiste Onofré a écrit : > Hi, > > Some days ago, we discussed about Decanter 2.0.0 and using "external" > instances of used engines, like Elasticsearch or Kibana. > > Basically, the main reason is that some engines are not easy to embed > in Karaf.
