Readme
Often we need a convenient way to manage inventories for Computers and Services. One way to do this is in databases or flat files, or dedicated services. Cloudmesh Inventory is designed to be at this time super simple and provides a list of computer entries that are used to document if a service is running on it. It uses a very small set of metadata to keep it extremely simple. All attribute values are strings. An example is
g001:
cluster: gregor
comment: test
host: g001
ip: 127.0.0.1
label: g001
metadata: None
name: g001
owners: gvonlasz
project: cloudmesh
service: compute
We explain our intended use of the attributes next
| Attribute | Description |
|---|---|
| cluster | The name of the cluster this entry is associated with |
| description | a description |
| comment | a comment |
| host | the unique name of the host |
| ip | the ip address |
| name | a unique hostname for the entry |
| label | a unique label that may include more than the hostname |
| metadata | a string in which metadata can be placed |
| owners | a list of owners of the machine (comma separated) |
| project | a string representiing a project name |
| service | a string representing the service |
| os | name of the operating system |
The manual for cloudmesh can be found at
Cloudmesh Inventory, however can also be used as standalone product.
Make sure you have a new version of python and pip. We tested with with versions greater then
You will need the followng other cloudmesh modules before you can install via pip:
$ pip insatll cloudmesh-common
$ pip insatll cloudmesh-cmd5
$ pip insatll cloudmesh-inventory
As developer we recommend yo use the instalation from source. For this we have a convenient cloudmesh installer program that outomates fetching the source and does the install for you. To install it form source use:
$ mkdir ~/cm
$ cd ~/cm
$ pip install cloudmesh-installer
$ cloudmesh-installer git clone inventory
$ cloudmesh-installer install inventory
This will clone a number of repositories in the cm directory and
install them with pip from them.
Your inventory will be located at
~/.cloudmesh/inventory.yaml
An example file will look as follows:
g001:
cluster: gregor
comment: test
host: g001
ip: 127.0.0.1
label: g001
metadata: None
name: g001
owners: gvonlasz
project: cloudmesh
service: compute
os: ubuntu20.04
g002:
cluster: gregor
comment: test
host: g002
ip: 127.0.0.1
label: g002
metadata: None
name: g002
owners: gvonlasz
project: cloudmesh
service: compute
os: ubuntu20.04
