Preguntas Frecuentes - FAQ

Elasticsearch is a powerful open source engine for search and analytics, that makes data easy to store and explore. Being focused on reliability, real-time analytics, and simple management, it is based on high performance and full-featured Java-powered Apache Lucene library, which helps to implement the provided advanced search and analytics capabilities. Herewith, a special RESTful API allows performing any action by means of a simple JSON over HTTP, making this solution truly developer-friendly.

• deploy Elasticsearch Docker container
• launch it
• update to the newest version

Being based on Docker standard, the Elasticsearch image can be provisioned for production-ready use at Apiqcloud PaaS in a few clicks, just like it’s described below:

1. Log into your Apiqcloud dashboard and click the New environment button at the top pane. In the opened wizard, switch to the Docker tab and click Select Container in the middle of the frame.

2. At the Search tab, type elasticsearch into the corresponding field and press Enter. Choose the same-named image within the appeared list by simply clicking on it.

Then, select the version you’d like to install by means of the drop-down menu at the top (as an example, we’ll choose the 2.0.2 one) and click Next to proceed.

3. Now, you can configure the general parameters of your environment - adjust the number of allocated resources using cloudlet sliders, select the desired region and type environment name.

To submit the creation, click the same-named button when ready.

4. That's all! In a minute, you'll get your ready-to-use Docker-based environment with Elasticsearch already deployed inside.

• The external IP address - the common choice, which ensures simple instance handling and faster response time, whilst being a paid option

• Endpoints - the free of charge alternative, provided by Apiqcloud

Connection via Public IP

In case you’ve attached an external IP address to your elasticsearch container, simply click the Open in browser button next to your environment and add the default 9200 port at the end of the address within the opened tab.

This way is standard and, as you can see, is maximally optimized for convenient usage.

Connection via Endpoints

If you’d like to leverage endpoints solution instead of spending the additional costs for external address utilization, you need to take into consideration that Elasticsearch requires the HTTP and transport.tcp services to be accessible from outside. Here, the first service is used for the incoming HTTP requests’ processing and the second one - for communication between nodes.

So, to make your deployed search engine to work properly, you’ll need to manually expose the appropriate ports via Apiqcloud Shared Load-Balancer for the corresponding container.

1. For that, click the Settings icon next to your environment, switch to the Endpoints section and select Add like it is shown in the image below:

2. Within the opened frame, define the required parameters for the first endpoint (i.e. the HTTP service entry point), exposing the 9200 container port:

Click Add to create.

3. Repeat the previous step for the transport service (9300 port). As a result, you should receive two endpoints, similar to the shown below:

For now, you are able to operate with your elasticsearch instance using the links within the Access URL column. To ensure everything is fine, navigate to the HTTP one.

That’s it! Now you can start building your own index of the required document-oriented data.

Apiqcloud provides an easy way to switch between the available Docker image tags, whilst saving all the inherent server configurations and data stored, with the distinctive container redeploy feature. So, in case of the necessity to upgrade your elasticsearch instance to the newly released version, just follow the next simple steps:

1. Click Redeploy container next to the required Docker container (or, if operating with several nodes, select the same button for the corresponding image name to update all of them at once).

2. Within the appeared frame, choose the desired Tag your application should be updated with (e.g. the latest one) and click Redeploy.

3. In a minute or so, you'll get your container updated. To check the exact Elasticsearch version that is currently run, just refer to its start page.

In such a way, you can move to the newest application version right after it is released without the mess of complex adjustments and special configurations.
