working with Livebook

[ndrean]

I tried without success to use snap from a Livebook. (also referenced in #94 ).

I installed finch (instead of Req) and run an OpenSearch image:

docker pull opensearchproject/opensearch:latest
docker pull opensearchproject/opensearch-dashboards:latest

docker run -d --name opensearch \
  -p 9200:9200  -p 9600:9600 \
  -e "discovery.type=single-node" \
  -e "OPENSEARCH_INITIAL_ADMIN_PASSWORD=a K 12 3 45 6 78 9?" \
  -e "cluster.name=my-cluster" \
  -e "node.name=node1" \
  -v open-search:/usr/share/opensearch/data \
  opensearchproject/opensearch:latest

The Livebook:

Mix.install([{:snap, "~> 0.11"}, {:finch, "~> 0.19"}])

defmodule MyApp.Cluster do
  use Snap.Cluster, opt_app: :noop
end

Finch.start_link(name: MyFinch)

{:ok, _} = Kino.start_child(
  {MyApp.Cluster, [
    url: "http://localhost:9200", 
    username: "admin",
    password: "a K 12 3 45 6 78 9#"
  ]
  }
)

I create an index and define a map with two fields "title" and "chunk_text" of type "text":

map = %{
  "mappings" => %{
    "properties" => %{
      "title" => %{"type" => "text"},
      "chunk_text" => %{
        "type" => "text",
        "fields" => %{
          "raw" => %{"type" => "keyword"}
        }
      }
    }
  }
}

Snap.Indexes.create(MyApp.Cluster, "my-index", map)

I get in the Livebook:

{:error, %Snap.HTTPClient.Error{reason: :closed, origin: %Mint.TransportError{reason: :closed}}}

and in the terminal (running livebook server)

[debug] Elasticsearch GET request path=/my-index/_doc status= response=12ms decode=0ms total=12ms

Besides the connection failure, the create index documentation indicates a PUT request whilst this generates GET request.
