:tada: Big shout out to the community in this release, well done!

Features

• helm: Add support to specify --kube-version (#578) (@olegmayko)
• kubectl: Add "validate" diff strategy with kubectl diff --server-side (#538)

:sparkles: Tanka now defaults to k8s-alpha

tk init will now install k8s-alpha as the default library for k.libsonnet. It is currently defaults to Kubernetes v1.20 however you can pick your own version or disable it:

tk init --k8s=1.18
tk init --k8s=false

Features

• cli :sparkles:: tk init now defaults to k8s-alpha (#563)

Bug Fixes

• kubernetes: Remove resources with altered state (#539) (@StevenPG)

Features

• helm: Add support for --no-hooks switch in Helm template (#545) (@PatTheSilent)
• export: Only call FindEnvs once (#553)

Bug Fixes

• kubernetes: Don't fail on listing namespaces (#549)

This is a minor release with one bugfix and one minor feature.

Features

• process: With 0.11.0, tanka started automatically adding namespaces to all manifests it processed. We updated this to not add a namespace to cluster-wide object types in order to make handling of these resources more consistent in different workflows. (#320)

Bug Fixes

• export: Fix inverted logic while checking if a file already exists. This broke tk export entirely. (#317)

2 months later and here we are with another release! Packed with many detail-improvements, this is what we want to highlight:

:sparkles: Enhanced Kubernetes resource handling

From now on, Tanka handles the resources it extracts from your Jsonnet output in an enhanced way:

1. Lists: Contents of lists, such as RoleBindingList are automatically flattened into the resource stream Tanka works with. This makes sure they are properly labeled for garbage collection, etc.
2. Default namespaces: While you could always define the default namespace (the one for resources without an explicit one) in spec.json, this information is now also persisted into the YAML returned by tk show and tk export. See https://tanka.dev/namespaces for more information.

:hammer: More powerful exporting

tk export can now do even more than just writing YAML files to disk:

1. --extension can be used to control the file-extension (defaults to .yaml)
2. When you put a / in your --format for the filename, Tanka creates a directory or you. This allows e.g. sorting by namespace: --format='{{.metadata.namespace}}/{{.kind}}-{{.metadata.name}}'
3. Using --merge, you can export multiple environments into the same directory tree, so you get the full YAML picture of your entire cluster!

:fax: Easier shell scripting

The tk env list command now has a --names option making it easy to operate on multiple environments:

# diff all environments:
for e in $(tk env list --names); do
  tk diff $e;
done

Also, to use a more granular subset of your environments, you can now use --selector / -l to match against metadata.labels of defined in your spec.json:

$ tk env list -l status=dev

Features

• cli: tk env list now supports label selectors, similar to kubectl get -l (#295)
• cli: If spec.apiServer of spec.json lacks a protocol, it now defaults to https (#289)
• cli: tk delete command to teardown environments (#313)

• cli: Support different file-extensions than .yaml for tk export (#294) (@marthjod)
• cli: Support creating sub-directories in tk export (#300) (@simonfrey)
• cli: Allow writing into existing folders during tk export (#314)

• tooling: tk tool imports now follows symbolic links (#302), (#303)

• process: List types are now unwrapped by Tanka itself (#306)
• process: Automatically set metadata.namespace to the value of spec.namespace if not set from Jsonnet (#312)

Bug Fixes

• jsonnet: Using import "tk" twice no longer panics (#290)
• tooling: tk tool imports no longer gets stuck when imports are recursive (#298)
• process: Fully deterministic recursion, so that error messages are consistent (#307)
