v5.3.0 - 03.02.2022

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 #938
• host pid mode support for k3s-server and k3s-agent by @hlts2 in #929
• SimpleConfig v1alpha4 by @iwilltry42 in #944
• add env var LOG_COLORS=[1|true|0|false] to toggle colored log output (enabled by default) by @iwilltry42 in #951
• Compatibility Tests by @iwilltry42 in #956
• Volume Shortcuts and k3d-managed volumes by @iwilltry42 in #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 #942

Changed

• Config file compatible with Kustomize by @erikgb in #945
• chore: update direct dependencies by @iwilltry42 in #935

Fixed

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

Deprecated

• SimpleConfig API version k3d.io/v1alpha3 is now deprecated in favor of k3d.io/v1alpha4

Removed

• unused volume validation functionality in cmd/util, does not affect the CLI (#916)

Compatibility

This release was automatically tested with the following setups:

Docker

• 20.10.5
• 20.10.12

Expected to Fail with the following versions:

• <= 20.10.4 (due to runc, see #807)

K3s

We test a full cluster lifecycle with different K3s channels, meaning that the following list refers to the current latest version released under the given channel:

• Channel v1.23
• Channel v1.22

Expected to Fail with the following versions:

• <= v1.18 (due to not included, but expected CoreDNS in K3s)

v5.2.1

v5.2.1

Features & Enhancements

• improved Podman compatibility (#868, @serverwentdown)
  • last missing piece: release of containers/podman#12328
• improved error handling and logs when waiting for container logs (ca47fac)

Fixes

New Contributors

• @serverwentdown made their first contribution in #868

Full Changelog: v5.2.0...v5.2.1

v5.2.1-rc.0

v5.2.1-rc.0

Changes

• fix replacing user-provided API host value with host.docker.internal: #879 fixing #876

v5.2.0

v5.2.0

Features & Enhancements

• Improve image import performance (#826, @sbaier1)
  • New flag: k3d image import --mode [auto | direct | tools]
    • tools is the old default, which spawns a k3d-tools container for importing
    • auto is the new default to automatically detect which mode should work best
    • direct directly streams the images into the node containers without the k3d-tools container
• Enhanced usability of nodefilters & error messages for wrong usage (#871)
• New command: k3d version list [k3s | k3d | k3d-proxy | k3d-tools] to get image tags that can be used with k3d (#870)
  • e.g. use k3d version list k3s --format repo to get the latest image available for K3s and use it via k3d cluster create --image <image>
  • Docs: docs/usage/commands/k3d_version_list.md

Fixes

• cluster network: reserve IP extra IP for k3d-tools container in k3d-managed IPAM to avoid conflicts
• process the SimpleConfig before validating it to avoid early exit in hostnetwork mode (#860)
• error out if K3D_FIX_DNS=1 is set and user tries to mount a file to /etc/resolv.conf (conflict)
• clusterStart: only run actions which are necessary given the start reason (e.g. cluster start vs. cluster create)
• fix injection of host.k3d.internal based on resolving host.docker.internal (#872)
  • also now uses host.docker.internal in kubeconfig based on certain conditions (see PR)

New Contributors

• @sbaier1 made their first contribution in #826

Full Changelog: v5.1.0...v5.2.0

v5.1.0

v5.1.0

Features

• clusterCreate: --image option (also in config file) magic words to follow K3s channels (#841)
  • latest/stable to follow latest/stable channels of K3s
  • +<channel> (prefix +) where <channel> can as well be latest or stable, but also e.g. v1.21
  • k3d will then check the K3s channel server to get the latest image for that channel

Enhancements

• nodeHooks: add descriptions and log them for more verbosity (#843)
• node create: inject host.k3d.internal into /etc/hosts similar to the cluster create command (#843)

Fix

• --network host: do not do any network magic (like host.k3d.internal injection, etc.) when host network is used (#844)

Misc

• CI/Makefile: build with -mod vendor
• docs: document using some K3s features in k3d, including servicelb, traefik, local-storage-provisioner and coredns (#845)

Full Changelog: v5.0.3...v5.1.0

v5.0.4-rc.0

build with -mod vendor
