From 737d72dc07e630231202fe1ae513c6195b6d250b Mon Sep 17 00:00:00 2001 From: Daniil Baturin Date: Tue, 29 May 2018 23:07:52 +0200 Subject: T667: add a migration script for converting "system gateway-address" to "protocols static route 0.0.0.0". Code-wise that option was in vyatta-cfg-quagga, but the syntax is inside "system", so let's keep the script under system too. --- src/migration-scripts/system/7-to-8 | 45 +++++++++++++++++++++++++++++++++++++ 1 file changed, 45 insertions(+) create mode 100755 src/migration-scripts/system/7-to-8 (limited to 'src/migration-scripts/system') diff --git a/src/migration-scripts/system/7-to-8 b/src/migration-scripts/system/7-to-8 new file mode 100755 index 000000000..4cbb21f17 --- /dev/null +++ b/src/migration-scripts/system/7-to-8 @@ -0,0 +1,45 @@ +#!/usr/bin/env python3 + +# Converts "system gateway-address" option to "protocols static route 0.0.0.0/0 next-hop $gw" + +import sys + +from vyos.configtree import ConfigTree + +if (len(sys.argv) < 1): + print("Must specify file name!") + sys.exit(1) + +file_name = sys.argv[1] + +with open(file_name, 'r') as f: + config_file = f.read() + +config = ConfigTree(config_file) + +if not config.exists(['system', 'gateway-address']): + # Nothing to do + sys.exit(0) +else: + # Save the address + gw = config.return_value(['system', 'gateway-address']) + + # Create the node for the new syntax + # Note: next-hop is a tag node, gateway address is its child, not a value + config.set(['protocols', 'static', 'route', '0.0.0.0/0', 'next-hop', gw]) + + # Delete the node with the old syntax + config.delete(['system', 'gateway-address']) + + # Now, the interesting part.
