Changelog

v0.6.0

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!
  • CNI is now the default networking plugin; by default the bridge and portmap plugins are used
  • 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 :)

Deprecations

  • As per v0.5.0, the v1alpha2 API version is the default. Going forward, the v1alpha1 API version is deprecated, and will be removed in a future release.

v0.5.0

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 with v1alpha1)
  • 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 :)

Internal Improvements

v0.3.0

Released: 18/06/2019

Major release with significant UX and internal improvements:

  • 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.
  • 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, and ignite 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, and ignite 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

v0.2.0

Released: 06/06/2019

Major release with significant improvements

  • 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

Use it

Download the attached binary, add it to $PATH, and execute the following commands:

$ ignite build weaveworks/ignite-ubuntu:v0.2.0 \
    --name ubuntu-image \
    --import-kernel ubuntu-kernel
$ ignite images
$ ignite kernels
$ ignite run ubuntu-image ubuntu-kernel --name my-vm
$ ignite ps
$ ignite logs my-vm
$ ignite attach my-vm

# Cleanup
$ ignite stop my-vm
$ ignite rm my-vm
$ ignite rmi ubuntu-image
$ ignite rmk ubuntu-kernel

Also make note of the known limitations

v0.1.0

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.
