Proxmox execute command

[x86]

Dear,

Again a few problems with the API. I am unable to send shell commands to the proxmox host via the API.
i.e.

$aCommands = array
(
    'pct exec ' . $iVMID . ' -- ls -al /'
);

var_dump ( $pApi->post ( '/nodes/' . $sNodeName . '/execute', array ( 'commands' => json_encode ( $aCommands ) ) ) );

The result will be:

array(1) {
[0]=>
array(2) {
["status"]=>
int(500)
["message"]=>
string(96) "pct exec 106 -- ls -al / is not a valid command at /usr/share/perl5/PVE/API2/Nodes.pm line 352.
"
}
}

Executing this command via putty works like a charm.

I cant also change special config vars of my LXC container via the API, i.e.
lxc.aa_profile: lxc-custom-mounts

Can someone help? Thanks.

The "/nodes/<NodeName>/execute" API call allows you to execute multiple API calls at once. It is not meant to execute arbitrary shell commands. I guess you should use ssh if you really want to do that.

What do you want to do exactly? Execute shell commands inside containers?

Ok thanks for the information. I created a script which deploys new LXC for customers. I did configure a CIFS share mount via DAB within the template (thats why I need to use the special config var; 'lxc.aa_profile: lxc-custom-mounts'). After creation I need to do a post deployment (install specific software for the customer, that's why I want to execute a script inside the container.

I also want to execute commands inside a container via the api. Is there an other solution than establishing an ssh connection to the node?

Currently not. But I would directly connect (ssh) to the container instead.

Yes, but i dont know the password since i am using this api for client vms. I only want to be able to enable root login with password after creating a container. I want to execute the replace command on the host therefore

I also looked for a solution. Because some of the default images for containers contain only root accounts. A direct container ssh is only possible after adding an additional user (or enabling ssh for root). So in my ansible automation I just want to add a user to the container via the proxmox api after creating a new container. Currently I have to do it via the "console" manually or using the "pct exec" command via ssh, ...

We added a new parameter called "--ssh-public-keys" to the the api/cli, see

# pct help create

I thought this solves the problem with ansible?

 

[Philipp Page]

Amazing, i will have a look at this asap and give you feedback

 

[Philipp Page]

Sorry, i did not read well. It does not allow to execute shell commands via the api right?

 

[bert2]

No it "only" adds ssh_keys from a file to the root account. At least I didn't manage to add keys to another account within the container. And if I got it right on command line, not via the api.

 

[fabian]

Yes, it only adds the keys to the root account. The rest is up to your automation tools

Hello,
I need to execute a shell command in node via API to delete the rrdcached file "/var/lib/rrdcached/db/pve2-vm" for VM when i delete the VM because i have the old stats for a VM which is replaced with another (same ID).
Any suggestion to solve this problem ?

 

[dietmar]

Please note that those statistics are replicated to all cluster nodes, so you would need to remove them on all nodes.

i don't have a cluster between nodes, i like just to fond a way to delete the rrdcached file when i remove a VM.
It's possible ? or i must change the API code ? thanks
