Weaveworks Ignite Versions Save

Ignite a Firecracker microVM

v0.5.3

4 years ago

This is the third patch release in the v0.5.X series, containing one enhancement that helps projects using the ignite binary parse version information without root.

Note: dependent modules were calculated with a newer version of go; see #433

Enhancements

  • backport: skip root requirement for ignite version (#430, @chanwit)

Trying it out / Next Steps!

In short:

export VERSION=v0.5.3
export GOARCH=$(go env GOARCH 2>/dev/null || echo "amd64")

for binary in ignite ignited; do
    echo "Installing ${binary}..."
    curl -sfLo ${binary} https://github.com/weaveworks/ignite/releases/download/${VERSION}/${binary}-${GOARCH}
    chmod +x ${binary}
    sudo mv ${binary} /usr/local/bin
done

OCI images for this release

v0.6.0

4 years ago

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 :tada:!

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.

New Features

  • Make containerd the default runtime and CNI the default network plugin (#371, @twelho)
  • Implement the containerd runtime for Ignite (#337, @twelho)
  • Add a default CNI bridge and portmap network for Ignite (#370, @twelho)

  • Switch to using weaveworks/gitops-toolkit (#359, @luxas)
  • Switch imports to utilize gitops-toolkit (#354, @luxas)
  • Simplify the CNI code by vendoring github.com/containerd/go-cni (#349, @luxas)
  • FileWatcher: Support internal moves without re-creating and multiple active moves at once (#341, @twelho)
  • Fix GOHOSTARCH propagation, tag development image for the host architecture only (#340, @twelho)
  • Fix ignite-spawn's formatting when performing cleanup on VM metadata (#336, @twelho)
  • Automatically optimize the size of an imported image (#335, @twelho)
  • Add shell autocompletion for ignited (#363, @silenceshell)

Bug Fixes

  • Add err as a param for log.Errorf (#367, @silenceshell)
  • Fix an issue in the GitDirectory loop when trying to commit without any actual changes (#369, @silenceshell)
  • GitOps: only change the VM state if it differs from the current one (#374, @twelho)
  • Move VM network removal to logically correct place (#373, @twelho)
  • Fix Docker client port mappings by actually exposing them after binding (#350, @twelho)

Documentation

  • Update the docs for v0.6.0 (#378, @luxas)
  • Docs: Bump latest Ignite version to v0.5.1 (#362, @silenceshell)
  • Change Read the Docs links to point to the stable branch in main README (#338, @twelho)

Trying it out / Next Steps!

NOTE: Stop your VMs before performing the upgrade, as the underlying container runtime has changed! In short:

export VERSION=v0.6.0
export ARCH=$([ $(uname -m) = "x86_64" ] && echo amd64 || echo arm64)

for binary in ignite ignited; do
    echo "Installing ${binary}..."

v0.5.0

4 years ago

This release consists of 54 noteworthy PRs from 12 contributors. We had 14 contributions from 8 external contributors, thanks :tada:!

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 :)
