proxmox API example for dummies

[P1fFpeaWf]

Hi there,

I do not have a degree in computer science nor did I developed web applications for the last 100 years.
So, let's say that proxmox's api - documentation is a quite overwhelming to me.

I found this post in this forum (how to create a lxc container with php)
https://forum.proxmox.com/threads/proxmox-php-api-create-lxc-container.39036/

But this did not helped, because I just do not know where to start.

What I was able to do, was to get some response from the node when sending a request via curl

curl -k -d 'username=USER@pve' --data-urlencode 'password=PASSWORD' https://NODE_URL:8006/api2/json/access/ticket

I get a "TICKET"

{"data":
{
"CSRFPreventionToken":"123456:SOME_SHORT_CRYPTICSTRING",
"username":"USERNAME@pve",
"ticket":"PVE:USERNAME@pve:12345556::SOME_VERYLONG_CRYPTICSTRING",
"cap":{"sdn":{},"nodes":{},"storage":{},"dc":{},"access":{},"vms":{"VM.Monitor":1,"VM.PowerMgmt":1
}}}}

So, what now?
How can I use this to start / stop a LXC or a VM?

BTW: My weapons of choice are bash scripts.

Bash really isn't great for that as you will have to do a lot of json parsing and string manipulations. Would be much easier to use a scripting language like python that got build in functions to do all this stuff.

Since your weapon of choice is Bash, have you tried the Proxmox command line tools like qm?

I’ve been able to do everything I’ve wanted to do with Bash and qm (or a few of the other standard PVE tools).

If your goal is just starting and stopping, qm will do that perfectly.

Manual for qm:

Yeah, qm (and pct) work fine, when I am logged into the proxmox node ( "qm start/stop 123" ).
My problem is, that I would like to start/stop VMs and LXCs from remote (local network).

hmm, a workaround would be to use

ssh root@NODE 'qm start/stop 123'

But I (probably) would not get the current status of the VM/LXC (?).

 

[Dunuin]

You can use qm list to get the status of VMs and pct list to get the status of LXCs.

Thanks.

After some ssh-key-coping I could run

ssh root@NODE "pct status 123"

, which returned a (correct)

status: stopped

.

@Dunuin : Thanks, "qm list" is quite a neat command to get a nice overview.

@moderator: Since running a the command through ssh is absolutely suitable for my needs, I consider this thread as solved.
