LXD 5.5 has been released

Introduction

The LXD team is very excited to announce the release of LXD 5.5!

This release introduces quite a few new exciting features, including the beginning of object storage support in LXD, as well as a number of smaller but very welcome additions and fixes.

Enjoy!

New features and highlights

Storage buckets (on Ceph)

LXD is getting support for object storage!

This is done by adding a whole new concept of storage buckets along with dedicated command (lxc storage bucket) and APIs.

This allows LXD users to create new storage buckets, assign them a size limit and then manage access keys to that bucket. The bucket has its own URL with an S3 API.

Our initial implementation is limited to using Ceph with its rados gateway providing the S3 API. In LXD 5.6, we will be extending this feature to all other storage drivers through the use of minio.

Above you can see the creation of a new bucket and its use from a standard S3 client.

Instance Ready state

A common issue facing LXD users is knowing when an instance is ready to be used.
This isn’t something that LXD itself can help a lot about as the definition of “ready” is a pretty case specific one. But what LXD can do is let you tell it when ready and then expose this over the API.

The way this works is through our guest API (/dev/lxd):

stgraber@dakara:~$ lxc list u1
+------+---------+-----------------------+-------------------------------------------+-----------+-----------+
| NAME |  STATE  |         IPV4          |                   IPV6                    |   TYPE    | SNAPSHOTS |
+------+---------+-----------------------+-------------------------------------------+-----------+-----------+
| u1   | RUNNING | 172.17.250.107 (eth0) | 2602:fc62:b:250:216:3eff:feb9:e5bd (eth0) | CONTAINER | 0         |
+------+---------+-----------------------+-------------------------------------------+-----------+-----------+

stgraber@dakara:~$ lxc exec u1 bash
root@u1:~# curl --unix-socket /dev/lxd/sock lxd/1.0
{"state":"Started","api_version":"1.0","instance_type":"container","location":"none"}
root@u1:~# curl --unix-socket /dev/lxd/sock lxd/1.0 -X PATCH -d '{"state": "Ready"}'
root@u1:~# exit

stgraber@dakara:~$ lxc list u1
+------+-------+-----------------------+-------------------------------------------+-----------+-----------+
| NAME | STATE |         IPV4          |                   IPV6                    |   TYPE    | SNAPSHOTS |
+------+-------+-----------------------+-------------------------------------------+-----------+-----------+
| u1   | READY | 172.17.250.107 (eth0) | 2602:fc62:b:250:216:3eff:feb9:e5bd (eth0) | CONTAINER | 0         |
+------+-------+-----------------------+-------------------------------------------+-----------+-----------+

This works with both containers and virtual-machines so long as the devlxd API has not been disabled.

Configurable BGP hold time

A new bgp.peers.NAME.holdtime configuration key has been introduced.
This allows for setting a specific BGP hold time value on a peer, typically reducing it to a value much lower than the usual default of 180s.

All projects queries for storage volumes

Similar to what was done a few releases ago with the instances API, it’s now possible to retrieve volume information across projects by using the ?all-projects=true keyword in the URL.

stgraber@dakara:~$ lxc query /1.0/storage-pools/default/volumes?all-projects=true
[
    "/1.0/storage-pools/default/volumes/container/bgp-test",
    "/1.0/storage-pools/default/volumes/container/centos3",
    "/1.0/storage-pools/default/volumes/container/centos4",
    "/1.0/storage-pools/default/volumes/container/charmcraft-lxd-1779348-0-0-amd64?project=charmcraft",
    "/1.0/storage-pools/default/volumes/container/lxd-build",
    "/1.0/storage-pools/default/volumes/container/snapcraft-lxd",
    "/1.0/storage-pools/default/volumes/container/snapcraft-microceph-1142335?project=snapcraft",
    "/1.0/storage-pools/default/volumes/container/speedtest",
    "/1.0/storage-pools/default/volumes/container/u1",
    "/1.0/storage-pools/default/volumes/custom/backups",
    "/1.0/storage-pools/default/volumes/custom/images",
    "/1.0/storage-pools/default/volumes/virtual-machine/v1",
    "/1.0/storage-pools/default/volumes/virtual-machine/v2",
    "/1.0/storage-pools/default/volumes/virtual-machine/win11"
]

OOM kill counter in metrics

A new metrics API entry has been added to track the number of times the kernel Out Of Memory killer has been triggered.

stgraber@dakara:~$ lxc config set u1 limits.memory=64MiB
stgraber@dakara:~$ lxc query /1.0/metrics | grep lxd_memory_OOM_kills_total
# HELP lxd_memory_OOM_kills_total The number of out of memory kills.
# TYPE lxd_memory_OOM_kills_total counter
lxd_memory_OOM_kills_total{name="u1",project="default",type="container"} 0

stgraber@dakara:~$ lxc exec u1 -- apt update
Hit:1 http://archive.ubuntu.com/ubuntu focal InRelease
Hit:2 http://security.ubuntu.com/ubuntu focal-security InRelease
Hit:3 http://archive.ubuntu.com/ubuntu focal-updates InRelease
stgraber@dakara:~$ ts... 56% Killed

stgraber@dakara:~$ lxc query /1.0/metrics | grep lxd_memory_OOM_kills_total
# HELP lxd_memory_OOM_kills_total The number of out of memory kills.
# TYPE lxd_memory_OOM_kills_total counter
lxd_memory_OOM_kills_total{name="u1",project="default",type="container"} 1

Database optimization

And lastly, not really a new feature but a significant focus of this release.
A lot of work has gone into reducing the number of database requests performed by LXD as well as generally optimizing those requests.

This should provide better overall performance and avoid a number of timeouts that were hitting some larger cluster users.

LXD 5.5 is now in latest/candidate. Release to stable will happen early next week.

Live stream is scheduled for 2pm on Monday:

The new ready state looks great!

How exactly can LXD make use of bucket storage? Will it be possible to use it for images, or for exporting and importing containers?

We’re not currently planning on having LXD itself use the object storage feature.

It’s primarily meant for services inside of the instances which may be used to storing data inside of cloud object storage (S3, Google Storage, …) that will now be able to do so even on a completely local LXD deployment.

Are there plans to expose HTTPS rather than plaintext HTTP?

This is supported now, but its actually up to the configuration of the Ceph Radosgw that is being used.
If it is configured to use HTTPS then you can specify https://... in the cephobject.radosgsw.endpoint setting, in which case the returned URL in s3_url will also be https://....

Note if you are using a certificate on the rasosgw that is not in the main system certificate bundle you can also specify which certificates to trust using the cephobject.radosgsw.endpoint_cert_file setting on the cephobject pool.
