tmconfjs

tmconfjs provides a simple parser (tmconfjs command) to serialize a tmconf file (eg. /config/bigip.conf) to JSON. The produced JSON is printed to STDOUT or a specified file.

This project aims to be a minimalistic dependency free tool. It vendors the necessary code from the community project F5 BIG-IP Automation Config Converter (BIG-IP ACC).

The TMOS configuration parser f5-corkscrew is a more sophisticated alternative with advanced functionality and active development.

Documentation by example

Installation

npm install --global simonkowallik/tmconfjs

Command line usage

When installed globally, tmconfjs can be invoked as a command:

tmconfjs example/test.tmconf 2>/dev/null \
    | jq '."ltm profile client-ssl clientssl-secure"'

{
  "app-service": "none",
  "cert": "/Common/default.crt",
  "cert-key-chain": {
    "default": {
      "cert": "/Common/default.crt",
      "key": "/Common/default.key"
    }
  },
  "chain": "none",
  "ciphers": "ecdhe:rsa:!sslv3:!rc4:!exp:!des",
  "defaults-from": "/Common/clientssl",
  "inherit-certkeychain": "true",
  "key": "/Common/default.key",
  "options": [
    "no-ssl",
    "no-tlsv1.3"
  ],
  "passphrase": "none",
  "renegotiation": "disabled"
}

When this repo has been copied or cloned, invoke tmconfjs.js using node. An alternative is using npx, npx tmconfjs would work also. Errors, warnings or any debug information is written to STDERR:

node ./tmconfjs.js example/test.tmconf \
    >/dev/null 2> example/test.tmconf.log

cat example/test.tmconf.log

2024-02-23T21:47:31.594Z WARN UNRECOGNIZED LINE: '     auto-check enabled'
2024-02-23T21:47:31.595Z WARN UNRECOGNIZED LINE: '     auto-phonehome enabled'
2024-02-23T21:47:31.602Z WARN UNRECOGNIZED LINE: '	time 500'
2024-02-23T21:47:31.602Z WARN UNRECOGNIZED LINE: '	enabled yes'

Input is also accepted from STDIN:

cat example/imap.tmconf | node tmconfjs.js

{
    "ltm profile imap imap": {
        "activation-mode": "require"
    }
}

The <file_path> argument is preferred over STDIN however:

cat example/imap.tmconf | node tmconfjs.js example/pop3.tmconf

{
    "ltm profile pop3 pop3": {
        "activation-mode": "require"
    }
}

The output can be written to a specified file using --output or -o when STDOUT is not desired:

node tmconfjs.js --output example/pop3.json example/pop3.tmconf
cat example/pop3.json

{
    "ltm profile pop3 pop3": {
        "activation-mode": "require"
    }
}

More debug information is available and might help understand issues:

export LOG_LEVEL=debug
cat example/imap.tmconf | node tmconfjs.js example/pop3.tmconf 2> debug.log

{
    "ltm profile pop3 pop3": {
        "activation-mode": "require"
    }
}

cat debug.log

2024-02-23T21:54:04.300Z DEBUG Parsing from <file_path>: example/pop3.tmconf
2024-02-23T21:54:04.302Z DEBUG Parsing data

Container / Docker

Note the docker run options, --rm deletes the container right after it was executed and ended, -i run the container interactively (required for STDIN to work). Also note the absence of the common -t option, which indicates a TTY/terminal - STDIN would fail when this is used.

cat example/imap.tmconf | docker run --rm -i simonkowallik/tmconfjs

{
    "ltm profile imap imap": {
        "activation-mode": "require"
    }
}

Using volumes is another option:

docker run --rm -v $PWD/example:/data simonkowallik/tmconfjs \
    tmconfjs /data/pop3.tmconf -o /data/pop3.json

cat example/pop3.json

{
    "ltm profile pop3 pop3": {
        "activation-mode": "require"
    }
}

Use as module

A simple demo.js is available at example/demo.js.

Just require either parse or parseFile. Both take a string as input, parse expects tmconf within the string while parseFile expects a path to a tmconf file.

// demo.js
'use strict'

// use parse function from tmconfjs.js
const parse = require('../tmconfjs.js').parse

const tmconf = `
ltm profile pop3 pop3 {
    activation-mode require
}`

// supply string with tmconf to parse function
const tmconfAsJSON = parse(tmconf)

console.log(JSON.stringify(tmconfAsJSON, null, 4))

node example/demo.js

{
    "ltm profile pop3 pop3": {
        "activation-mode": "require"
    }
}
