The cluster has not formed yet, i.e. its health RED. Error of the security index is a victim of it. You need fix the cluster formation issue first. If cache is the issue as suggested by [this post](https://discuss.elastic.co/t/in-docker-docker-compose-i-got-some-errors/307489), I guess it might be related to the persistent volume created by docker-compose. If what you want is a fresh cluster, you should delete them. You can check the volume with something like

```auto
docker volume ls

```

and delete the relevant ones declared in the docker compose file. **NOTE** please be sure that you absolutely do not need any data from the volumes before deleting because you will _not_ be able to recover them later.
