Obtain Information About a VCH

You can obtain information about a virtual container host (VCH) by using the vic-machine inspect command.

The vic-machine inspect command does not include any options in addition to the common options described in Common vic-machine Options.

Prerequisites

You have deployed a VCH.

Procedure

  1. On the system on which you run vic-machine, navigate to the directory that contains the vic-machine utility.
  2. Run the vic-machine inspect command.

    The following example includes the options required to obtain information about a named instance of a VCH from a simple vCenter Server environment.

    • You must specify the username and optionally the password, either in the --target option or separately in the --user and --password options.
    • If the VCH has a name other than the default name, virtual-container-host, you must specify the --name or --id option.
    • If multiple compute resources exist in the datacenter, you must specify the --compute-resource or --id option.
    • If your vSphere environment uses untrusted, self-signed certificates, you must also specify the thumbprint of the vCenter Server instance or ESXi host in the --thumbprint option. To obtain the thumbprint of the vCenter Server or ESXi host certificate, run vic-machine without the specifying the --thumbprint option. The inspection of the VCH fails, but the resulting error message includes the required certificate thumbprint. You can copy the thumbprint from the error message and run vic-machine again, including the --thumbprint option.

      NOTE: If you obtain the thumbprint by other means, use upper-case letters and colon delimitation in the thumbprint. Do not use space delimitation.

    $ vic-machine-operating_system inspect
     --target vcenter_server_username:password@vcenter_server_address
     --thumbprint certificate_thumbprint
     --name vch_name

Result

The vic-machine inspect command displays information about the VCH:

  • The VCH ID:
    VCH ID: VirtualMachine:vm-101
    The vSphere Managed Object Reference, or moref, of the VCH. You can use VCH ID when you run the vic-machine delete or debug commands. Using a VCH ID reduces the number of options that you need to specify when you run those commands.
  • The version of the vic-machine utility and the version of the VCH that you are inspecting.

    Installer version: vic_machine_version-vic_machine_build-git_commit
    VCH version: vch_version-vch_build-git_commit

  • The upgrade status of the VCH:

    VCH upgrade status: 
    Installer has same version as VCH
    No upgrade available with this installer version
    If vic-machine inspect reports a difference between the version or build number of vic-machine and the version or build number of the VCH, the upgrade status is Upgrade available.

  • The address of the VCH Admin portal for the VCH.

    VCH Admin Portal:
    https://vch_address:2378
  • The address at which the VCH publishes ports.

    vch_address
  • The Docker environment variables that container developers can use when connecting to this VCH.
    • VCH with full TLS authentication with trusted Certificate Authority certificates:
      DOCKER_TLS_VERIFY=1 
      DOCKER_CERT_PATH=path_to_certificates
      DOCKER_HOST=vch_address:2376
    • VCH with TLS authentication with untrusted self-signed certificates:
      DOCKER_HOST=vch_address:2376
    • VCH with no TLS authentication:
      DOCKER_HOST=vch_address:2375
  • The Docker command to use to connect to the Docker endpoint.
    • VCH with full TLS authentication with trusted Certificate Authority certificates:
      docker -H vch_address:2376 --tlsverify info
    • VCH with TLS authentication with untrusted self-signed certificates:
      docker -H vch_address:2376 --tls info
    • VCH with no TLS authentication:
      docker -H vch_address:2375 info
