Retrieving Inventory Information¶
The ANTA CLI offers multiple entrypoints to access data from your local inventory.
Inventory used of examples¶
Let’s consider the following inventory:
---
anta_inventory:
hosts:
- host: 172.20.20.101
name: DC1-SPINE1
tags: ["SPINE", "DC1"]
- host: 172.20.20.102
name: DC1-SPINE2
tags: ["SPINE", "DC1"]
- host: 172.20.20.111
name: DC1-LEAF1A
tags: ["LEAF", "DC1"]
- host: 172.20.20.112
name: DC1-LEAF1B
tags: ["LEAF", "DC1"]
- host: 172.20.20.121
name: DC1-BL1
tags: ["BL", "DC1"]
- host: 172.20.20.122
name: DC1-BL2
tags: ["BL", "DC1"]
- host: 172.20.20.201
name: DC2-SPINE1
tags: ["SPINE", "DC2"]
- host: 172.20.20.202
name: DC2-SPINE2
tags: ["SPINE", "DC2"]
- host: 172.20.20.211
name: DC2-LEAF1A
tags: ["LEAF", "DC2"]
- host: 172.20.20.212
name: DC2-LEAF1B
tags: ["LEAF", "DC2"]
- host: 172.20.20.221
name: DC2-BL1
tags: ["BL", "DC2"]
- host: 172.20.20.222
name: DC2-BL2
tags: ["BL", "DC2"]
Obtaining all configured tags¶
As most of ANTA’s commands accommodate tag filtering, this particular command is useful for enumerating all tags configured in the inventory. Running the anta get tags command will return a list of all tags that have been configured in the inventory.
Command overview¶
Usage: anta get tags [OPTIONS]
Get list of configured tags in user inventory.
Options:
-u, --username TEXT Username to connect to EOS [env var: ANTA_USERNAME;
required]
-p, --password TEXT Password to connect to EOS that must be provided. It
can be prompted using '--prompt' option. [env var:
ANTA_PASSWORD]
--enable-password TEXT Password to access EOS Privileged EXEC mode. It can
be prompted using '--prompt' option. Requires '--
enable' option. [env var: ANTA_ENABLE_PASSWORD]
--enable Some commands may require EOS Privileged EXEC mode.
This option tries to access this mode before sending
a command to the device. [env var: ANTA_ENABLE]
-P, --prompt Prompt for passwords if they are not provided. [env
var: ANTA_PROMPT]
--timeout FLOAT Global API timeout. This value will be used for all
devices. [env var: ANTA_TIMEOUT; default: 30.0]
--insecure Disable SSH Host Key validation. [env var:
ANTA_INSECURE]
--disable-cache Disable cache globally. [env var:
ANTA_DISABLE_CACHE]
-i, --inventory FILE Path to the inventory YAML file. [env var:
ANTA_INVENTORY; required]
--tags TEXT List of tags using comma as separator:
tag1,tag2,tag3. [env var: ANTA_TAGS]
--help Show this message and exit.
Example¶
To get the list of all configured tags in the inventory, run the following command:
anta get tags
Tags found:
[
"BL",
"DC1",
"DC2",
"LEAF",
"SPINE"
]
* note that tag all has been added by anta
Note
Even if you haven’t explicitly configured the all tag in the inventory, it is automatically added. This default tag allows to execute commands on all devices in the inventory when no tag is specified.
List devices in inventory¶
This command will list all devices available in the inventory. Using the --tags option, you can filter this list to only include devices with specific tags. The --connected option allows to display only the devices where a connection has been established.
Command overview¶
Usage: anta get inventory [OPTIONS]
Show inventory loaded in ANTA.
Options:
-u, --username TEXT Username to connect to EOS [env var:
ANTA_USERNAME; required]
-p, --password TEXT Password to connect to EOS that must be
provided. It can be prompted using '--prompt'
option. [env var: ANTA_PASSWORD]
--enable-password TEXT Password to access EOS Privileged EXEC mode.
It can be prompted using '--prompt' option.
Requires '--enable' option. [env var:
ANTA_ENABLE_PASSWORD]
--enable Some commands may require EOS Privileged EXEC
mode. This option tries to access this mode
before sending a command to the device. [env
var: ANTA_ENABLE]
-P, --prompt Prompt for passwords if they are not
provided. [env var: ANTA_PROMPT]
--timeout FLOAT Global API timeout. This value will be used
for all devices. [env var: ANTA_TIMEOUT;
default: 30.0]
--insecure Disable SSH Host Key validation. [env var:
ANTA_INSECURE]
--disable-cache Disable cache globally. [env var:
ANTA_DISABLE_CACHE]
-i, --inventory FILE Path to the inventory YAML file. [env var:
ANTA_INVENTORY; required]
--tags TEXT List of tags using comma as separator:
tag1,tag2,tag3. [env var: ANTA_TAGS]
--connected / --not-connected Display inventory after connection has been
created
--help Show this message and exit.
Tip
In its default mode, anta get inventory provides only information that doesn’t rely on a device connection. If you are interested in obtaining connection-dependent details, like the hardware model, please use the --connected option.
Example¶
To retrieve a comprehensive list of all devices along with their details, execute the following command. It will provide all the data loaded into the ANTA inventory from your inventory file.
anta get inventory --tags SPINE
Current inventory content is:
