Error starting service locally

[amitcomo]

When trying to work with the annon.api locally i get the following error:

Hello @amitcomo. Can you show the exact Bash command which you used to start the containers? Also, did you override any options in .env regarding nodes discovery?

Looks like it crashed because the distribution layer failed to start (the one which is responsible configuration invalidation/synchronization if you have more than one instance deployed).

[amitcomo]

1. I use the following docker-compose.yml to start the app & db containers:

version: '2'
services:
app:
image: "nebo15/annon.web"
links:
- "api:api"
depends_on:
- api
environment:
- MANAGEMENT_ENDPOINT=http://api:4001
- PUBLIC_ENDPOINT=http://api:4000
ports:
- "8080:8080"
postgres:
image: "nebo15/alpine-postgre:9.6.2"
ports:
- "5432"
environment:
- POSTGRES_DB=annon
- POSTGRES_USER=postgres
- POSTGRES_PASSWORD=postgres
# volumes:
# - '.postgres:/var/lib/postgresql/data'

2. I use intellij plugin to start the api service (the plugin - https://github.com/KronicDeth/intellij-elixir)
3. nodes discovery - no change here. I used the .env file with DB host & port change.

Appreciate your help

@amitcomo can you try running Annon with script from annon.infra?

I believe that it crashes because, by default, Annon uses Kubernetes for its auto-clustering. If you start the code with IDE plugin, it would start it in dev mode, won't override any defaults and fail. You should either pass environment variables to use different clustering strategy (SKYCLUSTER_STRATEGY=Cluster.Strategy.Epmd) or edit config.ex and replace the default value there with Cluster.Strategy.Epmd.

[amitcomo]

Thanks Andrew.
I use SKYCLUSTER_STRATEGY=Cluster.Strategy.Epmd (verified it)

[AndrewDryga]

I'll leave this issue open to reconsider defaults later.
