Released: 11/9/2020
We're happy to share that ignite can now be generally configured with a central config file. Check out the docs for how to configure ignite here.
Using this new config, it's no longer necessary to remember to pass --runtime
and --network-plugin
with every command.
You can choose your own default behavior.
Working with individual VM's is now also much less error-prone.
This release includes a new API version, v1alpha3
, which allows VM's to remember their runtime and network config.
There's no current tooling for migrating to the new VM API for live workloads. However, older API objects are forwards compatible, and restarting the workload should upgrade the API on disk. As always, taking any necessary backups and re-creating workloads is the safest upgrade path :)
As is tradition, we have fixed bugs: networking bugs, lifecycle bugs, little UX things -- check the list.
It's now possible to run ignite within nested container environements such as containerd-within-docker and WSL2. Detailed documentation for containerized setups will graduate from issue comments to the latest docs site soon.
It's really notable that our e2e test suite is getting more complete! It's great to work with a project where confidence improves with every new patch, haha!
Alongside this release, we've updated all of the base OS images with new release tools powered by GitHub Actions. We're not shipping any new kernels, so the default is the same as before -- new kernels will be pushed in an upcoming release.
This release consists of 52 noteworthy PR's from 10 contributors. 37 of these patches were sent by 6 external contributors. 7 patches were sent by 5 people new to the project; welcome! :) Thanks so much for using and contributing back to the project.

Released: 13/07/2020
The first patch release in the v0.7.X
series pulls in an important fix for the long-standing
networking issues in Ignite, with #638 merged
you should be able to seamlessly integrate with different CNI providers and implement multi-node
networking with Ignite VMs.
v0.7.1
also brings improvements to the GitOps functionality courtesy of @luxas
and link checking improvements by @dholbach. Thanks!

Released: 02/06/2020
We're excited to cut a large release. This release consists of 57 noteworthy PR's from 13 contributors. 27 of these patches were sent by 8 external contributors -- thanks so much for using and contributing back to the project!
Among some of the many patches, VM's can now be started in parallel. (Images should be pulled beforehand)
The ignite ssh
and ignite exec
commands now share a native go implementation.
We've added the ignite cp
command along with improved CLI UX through filtering, templating, and examples.
You can now also create and run VM's imperatively using YAML files with the --config
flags.
Performance and stability improvements in VM and network lifecycle should make using ignite more pleasant, and the various bugfixes allow newer versions of Ubuntu to start functioning.
Lastly, we're announcing initial support for ARM devices.
Our docker images for ignite-kernels as well os our OS images for Ubuntu and kubeadm now ship with a manifest
list and {}-arm64
tag.
We've pushed a fresh set of kernel and OS images to dockerhub to support this.
Check out our new guide for ARM -- try it out on your ARM server or RaspberryPi and let us know how it works for you.
It was difficult to condense all of that!
As a special note, Sunny(@darkowlzz) from the @StorageOS team has joined ignite as a maintainer. Thanks for all of your help, Sunny!

Released: 02/10/2019
We're excited to release v0.6.1
with usability improvements and lots of bug fixes :)
This release consists of 32 noteworthy PRs from 6 contributors over the past month.
We had 7 contributions from 4 external contributors. Thanks so much!
Ignite should now work with most installations of containerd -- even those that are installed underneath upstream docker.
Care has been taken with our installation instructions to ensure we are not breaking users docker installations.
We've also implemented a graceful fallback to older containerd-shim versions and now support containerd-shim-runc-v2.
This release also contains numerous fixes that make the CNI network plugin work much more reliably.
Connections to the internet from vm's using CNI should now work on most machines by default.
Please see the following user-facing change.
The default cni0
bridge has changed to a new ignite0
bridge introduced by the #460 bugfix. This comes with a new subnet as well.
We did this because the default CNI config shipped in v0.6.0
was a non-working configuration for most users.
You may continue to use the default CNI configuration. Nothing will change automatically.
If you are using your own CNI configuration, this does not affect you.
To migrate your running CNI networked vm's to the new default subnet, you can:
- install this new ignite version
- stop the relevant vm's
- delete the CNI network
- restart them
Example:
# first, upgrade to ignite v0.6.1
# list all vm's on the default 172.18.0.0/16 CNI network
sudo bin/ignite vm ls | grep '\b172.18.[0-9][0-9]*.[0-9][0-9]*\b'
# stop the listed vm's with the appropriate runtime
sudo bin/ignite stop my-containerd-vm
sudo bin/ignite stop my-docker-vm --runtime docker
# remove the old CNI network config
sudo rm -rf rm /etc/cni/net.d/
# optional: remove the old bridge
sudo ifconfig cni0 down
sudo ip link delete cni0
# restart your vm's
sudo bin/ignite start my-containerd-vm
sudo bin/ignite start my-docker-vm --runtime docker
# Your vm's will now have addresses configured in the 10.61.0.0/16 subnet.
# If they did not have internet connectivity before, they now should.

Released: 30/08/2019
Welcome to the v0.6.0
release, consisting of major underlying improvements, and a more efficient runtime.
This release consists of 25 noteworthy PRs from 4 contributors; although v0.5.0 was released just two weeks ago! We had 5 contributions from 2 external contributors, thanks 🎉!
The main themes of this release has been:
- containerd is now used as the default container runtime for higher security and speed, and less resource usage
- This means that Ignite doesn't depend on
docker
anymore!
- This means that Ignite doesn't depend on
- CNI is now the default networking plugin; by default the
bridge
andportmap
plugins are used- You can still use your third-party CNI implementation of choice, see the networking doc
- GitOps Toolkit refactor is complete; now everything you need to create your Git-backed application is available at https://github.com/weaveworks/gitops-toolkit
- Ignite is using this toolkit internally to perform its GitOps capabilities, now you can easily use this functionality, too!
- Bugfixes and usability improvements all around the place
Also, our documentation is now available at https://ignite.readthedocs.org. Check that site out whenever you need some information, or open an issue :)
- As per v0.5.0, the
v1alpha2
API version is the default. Going forward, thev1alpha1
API version is deprecated, and will be removed in a future release.

Released: 13/08/2019
This release consists of 54 noteworthy PRs from 12 contributors. We had 14 contributions from 8 external contributors, thanks 🎉!
The main themes of this release has been:
- Persistent Storage: Block Device support added as the first external volume type
- Improved API: We're continuously improving the API; this release contains
ignite.weave.works/v1alpha2
(still backwards-compatible withv1alpha1
) - Read-write GitOps: In GitOps mode, Ignite now also pushes the actual state in
.status
back to the repo - Refactoring towards a client-server model: We're now shipping
ignited
that holds the reconciling GitOps and Manifest Directory modes - Multi-platform: We're now shipping ARM 64-bit binaries that you can use on e.g. Packet (and eventually, Raspberry Pi 4!)
Also, our documentation is now available at https://ignite.readthedocs.org. Check that site out whenever you need some information, or open an issue :)

Released: 18/06/2019
- There is no longer a difference between an Ignite image and an OCI image, this is now the same thing.
- Ignite operates on OCI images directly, for both OS images and kernels. The kernel is expected to be coupled with the image given to
ignite run
, in/boot/vmlinux
.
- Ignite operates on OCI images directly, for both OS images and kernels. The kernel is expected to be coupled with the image given to
- It is now possible to do
ignite run [OCI image]
directly, and everything (e.g. pulling the image) is handled automatically. e.g.ignite run -i weaveworks/ignite-ubuntu
. - Now
ignite images
shows OCI images that are cached and ready to use, andignite kernels
the kernels already imported from base images. - Added an example usage guide for running a Kubernetes cluster in HA mode using kubeadm and Ignite.
- Removed
ignite build
, andignite image/kernel import
; as these are no longer needed - Importing an image from a tar file is no longer possible, package the contents in an OCI image instead
- Added a new command
ignite ssh [vm]
and flag:ignite run --ssh
. This allows for automatic SSH logins. - Now Ignite logs user-friendly messages by default. To get machine-readable output, use the
--quiet
flag. - Ignite now requires the user to be
root
. This will be revisited later, when the architecture has changed. - The command outputs and structure is now more user-friendly.
- Fixed several bugs both under the hood, and user-affecting ones
Released: 06/06/2019
- Ignite is now using
devicemapper
under the hood, for overlay snapshots for filesystem writes, allowing for image reuse, efficient use of space and way faster builds! - Added sample Ubuntu 18.04 and CentOS 7 OS images & a 4.19 kernel build
- Automatic network configuration, now the OS image doesn't need to enable DHCP, as that is done in the kernel
- Automatically populate
/etc/hosts
and/etc/resolv.conf
, too - Add an option to bind a port exposed by the VM to a host port (
ignite run -p 80:80
) - Add an option for modifying the kernel command line (
ignite run --kernel-args
) - Add an option to copy files from the host into the VM (
ignite run --copy-files
) - Add an option to specify the amount of cores, RAM, and overlay size (
ignite run --cpus 2 --memory 1024 --size 4GB
) - Removed the need for the Ignite container to run with
--privileged
- Allow for force-deletions of images, kernels and vms.
- Added documentation.
- Moved repo from luxas/ignite to weaveworks/ignite
Download the attached binary, add it to $PATH

$ ignite rmk ubuntu-kernel
Also make note of the known limitations
Released: 31/05/2019
This is the first, proof-of-concept version of Ignite. It has all the essential features, and a pretty complete implementation of the docker UX.
