Requirements

Minimum Requirements:

• CentOS 7 or Ubuntu 18 Virtual Machine. 
  • This should be a dedicated virtual machine with no other production applications running. Base OS packages should be installed and updated to the latest versions.
  • Internet connectivity. This is used to automatically install and configure software dependencies.
• vCPU/Core: 4
  • Example: Intel(R) Xeon(R) Platinum 8175M CPU @ 2.50GHz
• RAM: 16 GB
• NIC interface: 1
• Disks mounted to the Virtual Machine: 2*
  • Host OS: 100 GB minimum
  • Unable to show "metadata-from": No such page "_space_variables"
    /Docker storage: 
    • Recommended 1 TB. Minimum 500 GB.

• • • Disk space monitoring and alerting configured at safe threshold (for example, 80% used capacity)
    • Ability to expand disk space when it reaches threshold.
• Docker version 18.09.6
• Docker Compose version 1.24.0

*An additional disk/file system should be configured and mounted at /var/lib/docker/ prior to any installation activities. This provides greater flexibility and reliability on production systems. A sample configuration guide is provided under Configuring Storage for EdgeView and Docker section.
