Docker Install

The docker version of Essentia will run on most systems. Due to the portable, containerized nature of docker, the docker version of Essentia is easy to install.

Essentia’s docker version cannot launch worker instances and thus does not have the full scalability of Essentia. If you need to parallelize your analyis, you can use the cloud version of Essentia or contact essentia@auriq.com.

How to Install Essentia using Docker

Note

You must have root privileges to run some of the following steps. If you do not, please contact your system administrator.

Install Docker. For a CentOs system, follow the steps under “Install with yum” and then “Create a docker group” here: https://docs.docker.com/engine/installation/linux/centos/. For other systems, follow the steps to install docker for your system by going to that link and navigating to your system’s installation instructions using the left navigation bar.
Make sure any existing applications running on port 80 have been stopped. If you have apache server running, run:
```
sudo apachectl stop
```

Open your firewall to port 80. The Commands for a CentOS 7 Firewall are:

firewall-cmd --list-all-zones
firewall-cmd --permanent --add-port=80/tcp --zone=public
firewall-cmd --permanent --add-port=80/tcp --zone=internal
firewall-cmd --reload

Fetch and run the container from docker:

docker run --privileged -itd -e "container=docker"  -v /sys/fs/cgroup:/sys/fs/cgroup --name essentia -p 80:80 auriqsystems/essentia /usr/sbin/init

Check that the docker container is running. Run:

docker ps -a

# CONTAINER ID        IMAGE                   COMMAND             CREATED              STATUS              PORTS                                           NAMES

Start the apache server by running:

docker exec -dt essentia /home/start_server.sh

Login to the Essentia Data Lake Manager UI by accessing the url of the instance and entering the following login information:
```
Username: essentia
