Problem when creating an elasticsearch service

[templth]

Hello,

I try to create a service but got this error:

dokku elasticsearch:create myesservice
=====> Extracting config files
12e5e8f167f5df1b7fa6c60701d8782a3f322e697b63e52d7993442ed9e80f39
docker: Error response from daemon: endpoint with name dokku.elasticsearch.myesservice already exists in network bridge.

I did previously:

$ dokku elasticsearch:destroy myesservice

After run the create command, I have the following within Docker:

$ docker ps -a

CONTAINER ID        IMAGE                                           COMMAND                  CREATED             STATUS                     PORTS               NAMES
30ef765a1ed6        elasticsearch:6.7.1                             "/usr/local/bin/do..."   3 seconds ago       Created                                        dokku.elasticsearch.myesservice

I wonder if the service is correctly created...

Thanks for your help!

Did the container removal fail? We run tests for this in CI, but if you can file a failing test for this, I can take a closer look.

Thans for your answer!

With the command dokku elasticsearch:destroy myesservice, the container in docker is removed successfully...

Antoher strange thing, I link this service with my app and I got this error when deploying:

remote: docker: Error response from daemon: Cannot link to a non running container: /dokku.elasticsearch.myesservice AS /musing_pasteur/dokku-elasticsearch-myesservice.

How can I debug things to detect what is broken?

[josegonzalez]

Is the container created and running when you run that link command?

[templth]

In fact, the container for the elasticsearch service isn't running because of the error:

Error response from daemon: endpoint with name dokku.elasticsearch.myesservice already exists in network bridge
Error: failed to start containers: 5f2b9678de67

@josegonzalez I removed the endpoint from the network bridge:

docker network disconnect bridge dokku.elasticsearch.myesservice

and now I can start the elasticsearch service.

But when deploying now, I have this error:

docker: Error response from daemon: Cannot link to /dokku.elasticsearch.tripigo, as it does not belong to the default network.

but I have one in the bridge network:

docker network inspect bridge

I finally make the application start with a dokku ps:restart api.dev.web but the ELASTICSEARCH_URL configured during the linking doesn't seem to be reachable:

ConnectionError: getaddrinfo ENOTFOUND dokku-elasticsearch-myesservice dokku-elasticsearch-myesservice:9200

[josegonzalez]

Are you using a custom network of some sort? The plugins almost certainly won't support that, at least without manual editing, and since the core Dokku project doesn't support that out of the box, I don't think I'll have time to debug this issue.

[josegonzalez]

If you want to file a test in this repository as a pull request for replicating this issue, I can maybe dig further, but otherwise I don't have time to dig into this at the moment.

[templth]

No, I don't use a custom network...

[josegonzalez]

Oh I see what you mean.

You'll need to delete the currently existing/created container and then start your service.

[templth]

Yes I finally started the service and app (with the link), but the value in the ELASTICSEARCH_URL isn't a reachable address...

[josegonzalez]

You'll need to unlink and relink.

[templth]

@josegonzalez it works now! thanks for your help!
