Native tmsh/bash commands via REST API

I am not sure if this ability has been provided in newer code versions. Last I remember from this thread, it isn't directly feasible but you can do something similar to the idea proposed in the thread.

If you are looking for the iControl REST endpoint for executing a Unix command, that's

/mgmt/tm/util/bash

ls /tmp

curl -sku user:password -X POST -H "Content-type: application/json" \
  -d "{\"command\":\"run\", \"utilCmdArgs\": \"-c 'ls /tmp'\"}" \
  https:///mgmt/tm/util/bash 

You can run a tmsh command in the same manner (e.g.,

tmsh list ltm virtual

curl -sku user:password -X POST -H "Content-type: application/json" \
  -d "{\"command\":\"run\", \"utilCmdArgs\": \"-c 'tmsh list ltm virtual'\"}" \
  https:///mgmt/tm/util/bash 

Output lines are concatenated (not easy to read), so you may want to parse it by piping the result to

python -m json.tool | sed 's/\\n/\n/g'

Note that you will get 50x error when the execution of the specified command takes longer than a predefined timeout (about 60-90 seconds).

For more on the API, please refer to iControl REST API Reference Version 12.0.

Here is an example of bash over REST -

$ curl -sk -u 'admin:admin' -H 'Content-Type: application/json' -X POST  \
    -d '{"command": "run", "utilCmdArgs": "-c \"date -u\""}' \
    https://$HOST/mgmt/tm/util/bash | jq .
{
  "kind": "tm:util:bash:runstate",
  "command": "run",
  "utilCmdArgs": "-c \"date -u\"",
  "commandResult": "Fri Feb  3 01:11:56 UTC 2017\n"
}

Hi, is here any way how to call tmsh command within a partition?

To list virtuals under the partition /Test directly from bash, for example, you can use

echo

 bash -c 'echo "cd /Test; list ltm virtual" | tmsh'

That's what you want to send to the

/mgmt/tm/util/bash

  curl -sku admin:admin https://192.168.184.30/mgmt/tm/util/bash \
  -X POST -H "Content-Type: application/json" \
  -d "{\"command\":\"run\", \"utilCmdArgs\":\"-c 'echo \\\"cd /Test; list ltm virtual\\\" | tmsh'\"}"

Example output:

{
    "command": "run",
    "commandResult": "ltm virtual testvs {\n    destination 172.16.10.45:http\n    ip-protocol tcp\n    mask 255.255.255.255\n    partition Test\n    pool /Common/CentOS-All\n    profiles {\n        /Common/tcp { }\n    }\n    source 0.0.0.0/0\n    translate-address enabled\n    translate-port enabled\n    vs-index 7\n}\n",
    "kind": "tm:util:bash:runstate",
    "utilCmdArgs": "-c 'echo \"cd /Test; list ltm virtual\" | tmsh'"
}

Please be careful with the escaping sequences.

If you have a more complex tmsh call, consider writing a tmsh script and call it via the

/mgmt/tm/cli/script

curl -sku admin:admin https://192.168.184.30/mgmt/tm/cli/script

Obviously, it does not make any sense calling tmsh via bash via tmsh (the iControl REST is just a wrapper for tmsh). Look for an endpoint that you can call directly for your purpose.

I am trying tmsh_commandlist = open("tmsh_commandlist.txt") from the python program specified above. I created command file tmsh_commandlist.txt which has a tmsh command i want to execute "create ltm node TEST3 address 3.3.3.3". When i run the program it completes successfully however does not create the new node on the LTM itself. As per my understanding i just have to specify the ltm commands as we type it on the F5 CLI to the text file and this program will configure it on the device. Any suggestions What could be the problem.

Thanks

You can use the

/mgmt/tm/ltm/node

/mgmt/tm/util/bash

curl

tmsh create ltm node TEST3 address 3.3.3.3

curl -sku : https:///mgmt/tm/ltm/node \
  -X POST -H 'Content-type: application/json' \
  -d '{"name":"TEST3", "address":"3.3.3.3"}'

If Python is your choice, you may want to check the F5 Python SDK. See F5 Python SDK Documentation.
