Software Requirements

Operating System

The following table provides a list of the supported operating systems and their versions.

Operating System	Version
Ubuntu Linux	18.04+
CentOS	7.6+
RedHat Enterprise Linux	7.6+

On RHEL systems Akamas containers might need to be run in privileged mode depending on how Docker was installed on the system.

Software packages

The following table provides a list of the required Software Packages (also referred to as Akamas dependencies) together with their versions.

Software Package	Notes
Docker	Akamas is deployed as a set of containerized services running on Docker. During its operation Akamas launches different containers so access to the docker socket with enough permissions to run the container is required.
Docker Compose	Akamas containerized services are managed via Docker Compose. Docker Compose is strictly necessary to operate Akamas.
AWS CLI	Akamas container images are published in a private Amazon Elastic Container Registry (ECR) and are automatically downloaded during the on-line installation procedure. AWS CLI is required only during the installation phase if the server has internet access and can be skipped during an offline installation.

The exact version of these prerequisites is listed in the following table:

Software Package	Ubuntu	CentOS	RHEL
Docker	19.03+	1.13+	1.13+
Docker-compose	2.0+	2.0+	2.0+
AWS CLI	2.0.0+	2.0.0+	2.0.0+

Akamas user

To install and run Akamas it is recommended to create a dedicated user (usually "akamas"). The Akamas user is not required to be in the sudoers list but can be added to the docker (dockeroot) group so it can run docker and docker-compose commands.

Make sure that the Akamas user has the read, write, and execute permissions on /tmp. If your environment does not allow writing to the whole /tmp folder, please create a folder /tmp/build and assign read and write permission to the Akamas user on that folder.
