Various OpenStack tools

All utilities require OpenStack credentials present as environment variables.

Installation

$ pip install git+https://github.com/stackhpc/stackhpc-osutils

Gather baremetal nodes facts using server name

Query what keys are available for retrieval:

$ osutils.node -p openhpc -q '.driver_info.[]'
["deploy_kernel", "ipmi_address", "ipmi_username", "ipmi_password", "deploy_ramdisk"]

Get list of ipmi_address and format the output using jq:

$ osutils.node -p openhpc -q '.driver_info.ipmi_address' | jq
[
  {
    "value": "10.45.253.35",
    "key": "openhpc-login-0"
  },
  {
    "value": "10.45.253.11",
    "key": "openhpc-compute-0"
  },
  {
    "value": "10.45.253.12",
    "key": "openhpc-compute-1"
  }
]    

Use regex to filter server names:

$ osutils.node -p 'openhpc-.*0' -q '.driver_info.ipmi_address'
[{"value": "10.45.253.1", "key": "openhpc-login-0"}, {"value": "10.45.253.22", "key": "openhpc-compute-0"}]

Open tmux windows that match server name keyword

$ osutils.ipmi openhpc-compute
Opening tmux window: openhpc-compute-0
ipmitool -I lanplus -H 10.45.253.22 -U root -P calvin sol activate
Opening tmux window: openhpc-compute-1
ipmitool -I lanplus -H 10.45.253.35 -U root -P calvin sol activate
