Question: When importing items into my Rails app I keep getting the above error being raised by SearchKick on behalf of Elasticsearch.

I'm running Elasticsearch in a Docker. I start my app by running docker-compose up. I've tried running the command recommended above but i just get "No such file or directory" returned. Any ideas?

I do have port 9200 exposed to outside but nothing seems to help. Any ideas?

Answer: 
Indeed, running `curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'` as suggested by @[Nishant Saini](https://stackoverflow.com/users/1136371/nishant-saini) resolves the very similar issue I ran just into.

I hit disk watermarks limits on my machine.
Use the following command in `linux`:

```
 curl -s -H 'Content-Type: application/json' -XPUT 'http://localhost:9200/_all/_settings?pretty' -d ' {
    "index":{
             "blocks" : {"read_only_allow_delete":"false"}
    }
}'

```

the same command in `Kibana's DEV TOOL` format :

```
PUT _all/_settings
{
    "index":{
             "blocks" : {"read_only_allow_delete":"false"}
    }
}

```
