Pass userdata with CMK
Hi,
I'm trying to pass userdata in cmk command line during virtual machine
deployment but I can't figure how to do that.
Among other tests, I've tried something like that in a very basic shell
script:
#!/bin/bash
cli=cmk
template=7bf01470-e3a5-4f37-b035-023c663c1b48
service=80b47022-a341-446f-a14a-128b85a099d0
zone=530cb1c3-1c90-4055-816e-3b58fbf9de91
keypair=mykey
userdata="$(sed -E ':a;N;$!ba;s/\r{0,1}\n/\\n/g' user-data)"
$ cli deploy virtualmachine templateid="$template"
serviceofferingid="$service" zoneid="$zone" keypair="$keypair"
user-data="$userdata"
But I still can't figure how to make it.
Do you have any suggestions?
Many thanks.

Hello,
With the help of user data you can push you set of instructions to the VM while deploying VM. So let’s say you want to install any specific packages in the newly deployed VM, So instead of logging to the VM and download it manually you can pass the user-data to the VM while deploying the VM and it will get it done.
There are few prerequisites for user data which can be found in the ACS document,
http://docs.cloudstack.apache.org/projects/cloudstack-administration/en/4.8/virtual_machines/user-data.html#:~:text=CloudStack%20provides%20API%20access%20to,encoding%20to%20a%20deployed%20VM.&text=Deployed%20VMs%20also%20have%20access,user%2Ddata%20formated%20in%20base64. <http://docs.cloudstack.apache.org/projects/cloudstack-administration/en/4.8/virtual_machines/user-data.html#:~:text=CloudStack%20provides%20API%20access%20to,encoding%20to%20a%20deployed%20VM.&text=Deployed%20VMs%20also%20have%20access,user%2Ddata%20formated%20in%20base64.>
So basically once you have installed Cloud-init and other packages mentioned above In link. Then you need to covert you script/data into base64 format and then send via API command.
Let’s a say a script contains -
#! /bin/bash
echo “Hello CloudStack” >> /tmp/userdata.txt
Now convert above text into the base64 format. - You can use you Linux editor or you can use online tool for.
https://linuxhint.com/bash_base64_encode_decode/ <https://linuxhint.com/bash_base64_encode_decode/>
Or
https://www.base64encode.org/ <https://www.base64encode.org/>
Now I have tried to convert and it gave me - ‘IyEgL2Jpbi9iYXNoCgplY2hvIOKAnEhlbGxvIENsb3VkU3RhY2vigJ0gPj4gL3RtcC91c2VyZGF0YS50eHQK’, Now just pass the string while deploying you virtual machine.
i.e
Cloudmonkey deploy virtualmachine name=x, ….., userdata=IyEgL2Jpbi9iYXNoCgplY2hvIOKAnEhlbGxvIENsb3VkU3RhY2vigJ0gPj4gL3RtcC91c2VyZGF0YS50eHQK
I hope this will clarify your concern.

Thanks for your help guys. It's working now.
Here is my corrected script:
#!/bin/bash
cli=cmk
template=7bf01470-e3a5-4f37-b035-023c663c1b48
service=80b47022-a341-446f-a14a-128b85a099d0
zone=530cb1c3-1c90-4055-816e-3b58fbf9de91
keypair=mykey
userdata="$(base64 ./user-data)"
$cli deploy virtualmachine templateid="$template"
serviceofferingid="$service" zoneid="$zone" keypair="$keypair"
userdata="$userdata"
Have a nice day.

Re: Pass userdata with CMK

Hi,
You need to pass the userdata (not user-data) as a base64 encoded string (try https://www.base64encode.org/ or the base64 command on Linux).
template=7bf01470-e3a5-4f37-b035-023c663c1b48
service=80b47022-a341-446f-a14a-128b85a099d0
zone=530cb1c3-1c90-4055-816e-3b58fbf9de91
keypair=mykey
userdata="$(base64 ./user-data)"
cmk deploy virtualmachine templateid="$template"
serviceofferingid="$service" zoneid="$zone" keypair="$keypair"
userdata="$userdata"
Thanks,
David
