"Error while dialing" when using CouchDB

[fsalhab]

Hey, I have a network with 3 orgs and single peer that works perfectly when using LevelDb as option in the fablo-config.json file. However, when I change to CouchDb I start having this error:

I found a few similar issues but the solutions didn't work for me. I'm running Linux on a VM, but I have enough RAM so this isn't the problem. Also, all containers are running. This is my docker ps -a output:

I really appreciate any help!

Edit: Sometimes it works correctly when I do fablo recreate, but it's really inconsistent. Also, most of the times I do fablo reset it fails again, so I need to fix this.

I think that might be the case with a peer trying to connect CouchDB before it's ready. It seems we don't have depends_on section for peers in our Docker compose template: https://github.com/hyperledger-labs/fablo/blob/main/src/setup-docker/templates/fabric-docker/docker-compose.yaml

There should be something similar to:

  <%= peer.address %>:
    container_name: <%= peer.address %>
    ...
    <%_ if(peer.db.type==="CouchDb") { _%>
    depends_on:
      couchdb.<%= peer.name %>.<%= org.domain %>:
        condition: service_healthy
    <%_ } _%>
    networks:
      - basic

This PR #443 may close this issue.

The fix should be available in 1.2.1-unstable.0 version of Fablo
