Full Changelog: https://github.com/rancher/k3d/compare/v5.2.0...v5.2.1

v5.2.1-rc.0

Changes

• fix replacing user-provided API host value with host.docker.internal: https://github.com/rancher/k3d/pull/879 fixing https://github.com/rancher/k3d/issues/876

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)

Full Changelog: https://github.com/rancher/k3d/compare/v5.1.0...v5.2.0

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: https://github.com/rancher/k3d/compare/v5.0.3...v5.1.0

v5.0.3

Enhancements & Fixes

• simplified way of getting a Docker API Client that works with Docker Contexts and DOCKER_* environment variable configuration (#829, @dragonflylee)

Full Changelog: https://github.com/rancher/k3d/compare/v5.0.2...v5.0.3

v5.0.2

Enhancements

• CoreDNS Configmap is now edited in the auto-deploy manifest on disk instead of relying on kubectl patch command (#814)
• refactor: add cmd subcommands in a single function call (#819, @moeryomenko)
• handle ready-log-messages by type and intent & check them in single log streams instead of checking whole chunks every time (#818)

Fixes

• fix: config file check failing with env var expansion because unexpanded input file was checked

Misc

• cleanup: ensure that connections/streams are closed once unused (#818)
• cleanup: split type definitions across multiple files to increase readability (#818)
• docs: clarify node create help text about cluster reference (#808, @losinggeneration)
• refactor: move from io/ioutil (deprecated) to io and os packages (#827, @Juneezee)
