Preparing an Bare Metal or VMware vSphere host for ContainerX Manager (cxMgmt) installation - Prepared host

Detailed information can be found in the ContainerX install and administration guide

Deploy and Ubuntu 14.04.03 or newer series relase (14.04.xx)

  1. We recommend a host with 4 cores, 8GB of RAM and 40GB of hard disk space.
  2. (optional step - only needed if persistent storage is needed for containers) An NFS share to store persistent data volumes to be used by containers in bare metal clusters.
  • NFS server must allow write access to all CX hosts and CX management server.  
  1. Layer 3 (IP) connectivity between CX management server and CX hosts. For security reasons and as a general practice, we recommend using IP addresses that are non-routable from the public internet, such as RFC 1918 private addresses.
  2. Local user account with the private SHA key file or password in /etc/sudoers with NOPASSWD option at end of file (e.g. for user account ubuntu)
        ubuntu  ALL=(ALL:ALL) NOPASSWD:ALL
  3. ssh daemon installed and running on default port 22.
        yum install ssh-server
  4. Network security rules must allow following inbound network connections on CX management server and CX hosts:

Additionally, as container pools are deployed, additional ports need to be opened on specific CX hosts to allow inbound requests from CX management server as well as from any location in the on-premise network that can be used to run docker commands on that container pool. Host IP and port information for these rules can be obtained from the CX management UI under container pools.

Persistent Data storage (optional, Bare metal only)

  1. Deploy a NFS storage share with IP access to NFS ports for all Container Management hosts and Elastic Cluster servers 
  2. NFS share must allow write access to all Container Management hosts and Elastic Cluster servers.
