can I run apps on TrueNAS? What's the recommended way?

[Jon Krueger]

It would be handy for me to run a couple of small applications on the same box. It would reduce my power footprint, simplify system admin.

Is this possible? Would jails be the right way?

Thanks,

Seems like this how you do it:

Virtualization (Obsolete)

Notice about obsolete features in TrueNAS 13.0

And I want the files written by my jailed app to be available outside.
Seems like this is how you do it:

Solved - [Solved] Accessing ZFS pool from jails

Hi guys, I'm new to BSD FreeBSD and I'm setting up a headless file server that will also run a couple of other services. At the moment I'm trying to run NFS and Deluge in separate jails, and they will both need access to my main ZFS pool which is mounted at /storage on the host. What is the...

Am I headed in the right direction?

Looks like it. Only disagreement I'd have would be to use SSH to access the server, and do your best to forget the "shell" button in the web GUI exists.

It works!!

I am now the proud owner of a TrueNAS Mini X. I found the web GUI a great help in setting up the jail and mount. My little app is now on the air. Thanks for your help!

Looks like TrueNAS Scale would be the go to for applications:

Depends on what you want to do. If you want to be able to install arbitrary software in a Unix environment, a jail (and therefore CORE) may well be the better way to go. If you want (pretty much) point-and-click deployment of apps that are in a particular catalog, it's probably SCALE.

This is working astoundingly well and I want to know why.

The jail name is known to my router: was that mDNS?

The router DHCP gives it an IP different from the NAS: is that because the jail has its own MAC? How did the jail get its own MAC?

 

[Jon Krueger]

This in turn lets me ssh to the jail if I choose: the setup was straightforward and well documented and easy to find:

/coretutorials/jailspluginsvms/

The requirement to do sshd_enable="YES" was mentioned by service start. Exactly the kind of hint that helps.

I then recalled I had another small service that needed a separate IP. I put it in the jail and it just worked.

Then from the above I realized it could use the jail name instead of IP. That just worked.

Outstanding.

How did the jail get its own MAC?

It makes it up.

 

[Jon Krueger]

It makes it up.

And how does the NIC respond to two different MACs?

Jails are pretty cool! When you use the VNET option, the jail creates a virtual network stack. Read up on man vnet for more information.
