System requirements of an Edge site

If you want to use Edge, you must make sure that the following system requirements are met.

System requirements

You need the following requirements to install and use an Edge site.

Software requirements

  • You can install the Edge software on the following Linux servers:
    • CentOS/RedHat Enterprise Linux 8.1, 8.2, 8.3 and 8.4
    • CentOS/RHEL 7.7, 7.8 and 7.9.

      Note As of the 2021.11 release, these versions are deprecated. The support for these versions ends with the 2022.03 release..

  • The sudo package is installed on the Linux host.
  • The user who installs Edge has full sudo access (ALL=(ALL) ALL)
Tip If you are an early adopter or you use Edge for beta testing purposes, we highly recommend to disable SELinux.

Hardware requirements

You need the following minimum hardware requirements:

  • 64 GB memory
  • 16 core CPU
  • You have mounted at least 50 GB of dedicated storage for the core installation of Edge sites.

    Warning Any data in this location is fully managed by the Edge site, do not save any other data in here as it can be removed by Edge without notification.

  • You have mounted at least 500 GB of dedicated storage for the Edge site data on a freely chosen mountpoint, for example /var/edge/storage. 

    mkdir -p /var/edge/storage
mkfs.xfs /dev/<block-device-name>
mount /dev/<block-device-name> /var/edge/storage
echo '/dev/<block-device-name> /var/edge/storage xfs defaults 0 0' >> /etc/fstab
    Note  Change <block-device-name> to the name of the device that contains the storage.

    Warning This dedicated storage should not be shared with other services as Edge can delete and overwrite files on this location without notice, so don't use /home/<username> or /var.

Warning When new capabilities are added in the future, the hardware requirements may change.

Network requirements

  • An Edge site needs outbound connections to all of the following:
    • The URL of your Collibra Data Intelligence Cloud environment
    • https://ingest.eu0.signalfx.com
    • https://http-intake.logs.datadoghq.com
    • https://*.repository.collibra.io
    • https://edge-docker-delivery.repository.collibra.io
  • Your Edge site has to be able to connect to port 443.
  • The resolve configuration file of your Linux host has maximum three search domains and two name servers.

Note If a firewall is enabled, run the following commands to add the cni0 and loopback interfaces to a trusted zone, so that Kubernetes can use it between its services: 

firewall-cmd --zone=trusted --change-interface=cni0 --permanent
firewall-cmd --zone=trusted --change-interface=lo --permanent
firewall-cmd --reload
