Merge BIG-IP Config Files
Problem this snippet solves:
This script will take a local BIG-IP configuration file, upload it to the BIG-IP, merge it with the existing configuration, then clean up the iControl REST upload folder (/var/config/rest/downloads) by removing the file.
How to use this snippet:
macdaddy:scripts jrahm$ python merge_config.py usage: merge_config.py [-h] host username filepath
Code :
def _upload(host, creds, fp): chunk_size = 512 * 1024 headers = { 'Content-Type': 'application/octet-stream' } fileobj = open(fp, 'rb') filename = os.path.basename(fp) if os.path.splitext(filename)[-1] == '.iso': uri = 'https://%s/mgmt/cm/autodeploy/software-image-uploads/%s' % (host, filename) else: uri = 'https://%s/mgmt/shared/file-transfer/uploads/%s' % (host, filename) requests.packages.urllib3.disable_warnings() size = os.path.getsize(fp) start = 0 while True: file_slice = fileobj.read(chunk_size) if not file_slice: break current_bytes = len(file_slice) if current_bytes < chunk_size: end = size else: end = start + current_bytes content_range = "%s-%s/%s" % (start, end - 1, size) headers['Content-Range'] = content_range requests.post(uri, auth=creds, data=file_slice, headers=headers, verify=False) start += current_bytes def _merge_config(host, creds, file): requests.packages.urllib3.disable_warnings() b_url = 'https://%s/mgmt/tm/sys/config' % host b = requests.session() b.auth = creds b.verify = False b.headers.update({'Content-Type': 'application/json'}) options = {} options['file'] = '/var/config/rest/downloads/%s' % file options['merge'] = True payload = {} payload['command'] = 'load' payload['options'] = [options] try: merge = b.post(b_url, json.dumps(payload)) if merge.status_code is not 200: print "Merge failed, check rest log file" exit() except Exception, e: print e def _cleanup_mergefile(host, creds, file): requests.packages.urllib3.disable_warnings() b_url = 'https://%s/mgmt/tm/util/unix-rm' % host b = requests.session() b.auth = creds b.verify = False b.headers.update({'Content-Type': 'application/json'}) payload = {} payload['command'] = 'run' payload['utilCmdArgs'] = '/var/config/rest/downloads/%s' % file try: cleanup = b.post(b_url, json.dumps(payload)) if cleanup.status_code is not 200: print "Cleanup failed, please check system." except Exception, e: print e if __name__ == "__main__": import os, requests, json, argparse, getpass requests.packages.urllib3.disable_warnings() parser = argparse.ArgumentParser(description='Merge a config file into BIG-IP config') parser.add_argument("host", help='BIG-IP IP or Hostname', ) parser.add_argument("username", help='BIG-IP Username') parser.add_argument("filepath", help='Merge file (with Absolute Path)') args = vars(parser.parse_args()) hostname = args['host'] username = args['username'] filepath = args['filepath'] print "%s, enter your password: " % args['username'], password = getpass.getpass() _upload(hostname, (username, password), filepath) filename = os.path.basename(filepath) _merge_config(hostname, (username, password), filename) _cleanup_mergefile(hostname, (username, password), filename)
