ESXi 6.5 Kickstart Python Script joining to vCenter VCSA6.5

[mark_l_zhang]

Please refer my documents on ESXi 5.5 and 6.0.

ESXi Kickstart Python Script joining to vCenter VCSA6.5

Now please check the ESXi 6.5 join the vCenter VCSA 6.5 through the python script.

The ESXi 6.5 has the python 3.0, so the previous scripts failed due to different language.

These are some tips I tried to update the scripts:

1 use the 2to3.

2 replace urllib2 urllib.request.

3 bytes in python3 instead of str in python2.

OK. Check the following codes:

import sys,re,os,urllib.request,urllib.parse,urllib.error,base64,syslog,socket, ssl
def stringToBase64(s):
 return base64.b64encode (s.encode ('utf-8'))
def base64ToString(b):
 return base64.b64decode (b).decode ('utf-8')
# vCenter server
vcenter_server = VCSA_IP
# vCenter Cluster path
cluster = Cluster
# vCenter credentials using encoded base64 password
vc_username = "Account"
vc_encodedpassword = "Password"
vc_password = base64ToString (vc_encodedpassword)
# ESX(i) credentials using encoded base64 password
host_username = "root"
host_encodedpasssword = "Hash"
host_password = base64ToString (host_encodedpasssword)
