How to do it…

Before installing ECE, the following prerequisities are to be checked:

1. Your user must be a Docker enabled one. In the case of an error due to a non-Docker user, add your user with sudo usermod -aG docker $USER.
2. In the case of an error when you try to access /mnt/data, give your user permission to access this directory.
3. You need to add the following line to your /etc/sysctl.conf (a reboot is required): vm.max_map_count = 262144.

1. To be able to use the ECE, it must initially be installed on the first host, as follows:

bash <(curl -fsSL https://download.elastic.co/cloud/elastic-cloud-enterprise.sh) install

The installation process should manage these steps automatically, as shown in the following screenshot:

At the end, the installer should provide your credentials so that you can access your cluster in a similar output, as follows:

Now you can access the Cloud UI using the following addresses:
http://192.168.1.244:12400
https://192.168.1.244:12443

Roles tokens for adding hosts to this installation:
Basic token (Don't forget to assign roles to new runners in the Cloud UI after installation.)

Allocator token (Simply need more capacity to run Elasticsearch clusters and Kibana? Use this token.)

Emergency token (Lost all of your coordinators? This token will save your installation.)

To add hosts to this Elastic Cloud Enterprise installation, include the following parameters when you install the software
on additional hosts: --coordinator-host 192.168.1.244 --roles-token 'eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJiZDI3NjZjZi1iNWExLTQ4YTYtYTRlZi1iYzE4NTlkYjQ5ZmEiLCJyb2xlcyI6W10sImlzcyI6ImN1cnJlbnQiLCJwZXJzaXN0ZW50Ijp0cnVlfQ.lbh9oYPiJjpy7gI3I-_yFBz9T0blwNbbwtWF_-c_D3M'

These instructions use the basic token, but you can substitute one of the other tokens provided. You can also generate your own tokens. For example:
curl -H 'Content-Type: application/json' -u
admin: OCqHHqvF0JazwXPm48wfEHTKN0euEtn9YWyWe1gwbs8 http://192.168.1.244:12300/api/v1/platform/configuration/security/enrollment-tokens -d '{ "persistent": true, "roles": [ "allocator"] }'

To learn more about generating tokens, see Generate Role Tokens in the documentation.

System secrets have been generated and stored in /mnt/data/elastic/bootstrap-state/bootstrap-secrets.json.
Keep the information in the bootstrap-secrets.json file secure by removing the file and placing it into secure storage, for example.

1. In my case, I can access the installed interface at http://192.168.1.244:12400.

After logging into the admin interface, you will see your actual cloud state, as follows:

1. You can now press on Create Deployment to fire your first Elasticsearch cluster, as follows:

1. You need to define a name (that is, a book-cluster). Using standard options for this is okay. After pressing Create Deployment, ECE will start to build your cluster, as follows:

1. After a few minutes, the cluster should be up and running, as follows:
