v0.6.0

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
  • 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.

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}..."
    curl -sfLo ${binary} https://github.com/weaveworks/ignite/releases/download/${VERSION}/${binary}-${ARCH}
    chmod +x ${binary}
    sudo mv ${binary} /usr/local/bin
done

# Install the CNI plugins if you don't already have them
export CNI_VERSION=v0.8.2
curl -sSL https://github.com/containernetworking/plugins/releases/download/${CNI_VERSION}/cni-plugins-linux-${ARCH}-${CNI_VERSION}.tgz | tar -xz -C /opt/cni/bin
