KCE.cr

GitHub release Docs

KCE (Kubeconfig Context Extractor) extracts sections of KUBECONFIG file based on selected context.

Since context includes cluster, and user name, extracting all relevant sections allows creating fully working KUBECONFIG for selected context.

Same functionality can be achieved with native kubectl command

kubectl --context=${context_name} config view --minify --flatten

Add kce to shard.yml dependencies

dependencies:
  kce:
    github: anapsix/kce.cr

KCE

require "kce"

kce = KCE.new("my-context", "/path/to/kubeconfig")
puts kce.kubeconfig     # => path to selected KUBECONFIG file
puts kce.kubecontext    # => selected kubecontext ("my-context")
puts kce.config         # => "my-context" config as Object (from YAML)
puts kce.config.to_yaml # => "my-context" config as String (from YAML)

config = KCE.config("my-context", "/path/to/kubeconfig")
puts config         # => "my-context" config as Object (from YAML)
puts config.to_yaml # => "my-context" config as String (from YAML)

KCE::ConfigReader

require "kce/configreader"

# getting config via instance method
reader = KCE::ConfigReader.new # will use `KUBECONFIG` env variable if set
kubeconfig = reader.config     # otherwise `$HOME/.kube/config`
puts kubeconfig                # => original KUBECONFIG as Object (from YAML)
puts kubeconfig.to_yaml        # => original KUBECONFIG as String (from YAML)

# reading from alternative path
reader = KCE::ConfigReader.new("/path/to/kubeconfig")

# getting config via class method
kubeconfig = KCE::ConfigReader.config("/path/to/kubeconfig")
