How to connect Elasticsearch through docker

[testmember012]

I did a setup of development environment using your Docker documetation. Setup was successful but while creating Elasticsearch connection, I get the following error : Could not connect to the Elasticsearch instance at http://elasticsearch:9200. Please check the endpoint URL and authentication settings. The details I used are: Endpoint URL : http://elasticsearch:9200 Username : elastic Password : changeme

I had tried http://localhost:5601/ as Endpoint URL too, but that also gave the same error. Am I using the correct details or is there any step that I had missed ?

Hi @testmember012,

There are some points you could check to help figure out what's going wrong:

• First, check that your containers are running once the docker-compose up has been executed. You could do that by doing a docker ps command to see if the containers appear in the list. If they are not, chances are you have some errors or issues preventing the containers from starting and you should check those in the first place.
• Second, if you are running your apache and php server locally (ie not in docker containers), you should replace the name of the containers with localhost or your local IP in order to connect to the elascticsearch instance (endpoint should be http://localhost:9200 or http://xx.xx.xx.xx:9200). Note that 5601 port is meant to access the Kibana web tool, not the elasticsearch instance. Accessing http://localhost:9200 should show you the default json payload. Something like:

  {
  "name" : "szLA31y",
  "cluster_name" : "yii2-test-cluster",
  "cluster_uuid" : "gvvwC9WvSjOrwRi8laBc6w",
  "version" : {
    "number" : "6.1.4",
    "build_hash" : "d838f2d",
    "build_date" : "2018-03-14T08:28:22.470Z",
    "build_snapshot" : false,
    "lucene_version" : "7.1.0",
    "minimum_wire_compatibility_version" : "5.6.0",
    "minimum_index_compatibility_version" : "5.0.0"
  },
  "tagline" : "You Know, for Search"
  }

• Third, if you are running you apache and/or php-fpm server in docker containers, you should check that all the containers are running on the same shared network (see the networks parameter in the docker-compose file, in our example, it is named app_tier). This is important so that your php container can access your elasticsearch container. Also, do not forget to add an extra_hosts parameter as indicated in the documentation so that your php container can access the Craft site through the apache container.

Please, let us know if you still have issues.

Thanks. After changing the container name Elasticsearch connection was successful.
