k3d - v5.3.0

v5.3.0 - 03.02.2022

Note: Now trying to follow a standard scheme defined by https://keepachangelog.com/en/1.0.0/

Added

• new config options to configure extra hosts by @iwilltry42 in https://github.com/rancher/k3d/pull/938
• host pid mode support for k3s-server and k3s-agent by @hlts2 in https://github.com/rancher/k3d/pull/929
• SimpleConfig v1alpha4 by @iwilltry42 in https://github.com/rancher/k3d/pull/944
• add env var LOG_COLORS=[1|true|0|false] to toggle colored log output (enabled by default) by @iwilltry42 in https://github.com/rancher/k3d/pull/951
• Compatibility Tests by @iwilltry42 in https://github.com/rancher/k3d/pull/956
• Volume Shortcuts and k3d-managed volumes by @iwilltry42 in https://github.com/rancher/k3d/pull/916
• Use some destination shortcuts with the --volume/-v flag that k3d automatically expands
  • k3s-storage -> /var/lib/rancher/k3s/storage
  • k3s-manifests -> /var/lib/rancher/k3s/server/manifests
  • k3s-manifests-custom -> /var/lib/rancher/k3s/server/manifests/custom (not K3s default: this is just some sub-directory inside the auto-deploy manifests directory which will also be parsed)
  • k3s-containerd -> /var/lib/rancher/k3s/agent/etc/containerd/config.toml (use with caution, K3s generates this file!)
  • k3s-containerd-tmpl -> /var/lib/rancher/k3s/agent/etc/containerd/config.toml.tmpl (used by K3s to generate the real config above)
  • k3s-registry-config -> /etc/rancher/k3s/registries.yaml (or just use --registry-config)
• k3d-managed volumes
  • non-existing named volumes starting with a k3d- prefix will now be created and managed by k3d
• JSON schema versions in-repo to link to from schemastore.org by @iwilltry42 in https://github.com/rancher/k3d/pull/942

Changed

• chore: update direct dependencies by @iwilltry42 in https://github.com/rancher/k3d/pull/935

Fixed

• serverlb should be created before using and restarted unless stopped by @wymli in https://github.com/rancher/k3d/pull/948
• fix typo in node.go by @eltociear in https://github.com/rancher/k3d/pull/949
• mutex on ensureToolsNode to avoid duplicate container name causing error by @iwilltry42 in https://github.com/rancher/k3d/pull/952
• detect '--disable=coredns' and conditionally disable injection by @iwilltry42 in https://github.com/rancher/k3d/pull/955
• invert logic for LOG_LEVEL parsing by @myitcv in https://github.com/rancher/k3d/pull/958
