module Bindings

Wraps each Bindings::Binding in a Bindings::CacheBinding.

@param [Array<Bindings::Binding>] bindings the bindings to wrap @return [Array<Bindings::Binding>] the wrapped bindings

# File lib/bindings.rb, line 31
def self.cached(bindings)
  bindings.map { |v| Bindings::CacheBinding.new(v) }
end

Returns zero or more Bindings with a given type and provider. If type or provider are None, the result is not filter on that argument. Comparisons are case-insensitive.

@param [Array<Bindings::Binding>] bindings the bindings to filter @param [String] type the type of the binding to find @param [nil] type @param [String] provider the provider of the binding to find @param [nil] provider @return [Array<Bindings::Binding>] the collection of bindings ith a given type and provider

# File lib/bindings.rb, line 82
def self.filter(bindings, type = nil, provider = nil)
  match = []

  bindings.each do |b|
    next unless type.nil? || type_matches?(b, type)
    next unless provider.nil? || provider_matches?(b, provider)

    match.append(b)
  end

  match
end

Returns a Bindings::Binding with a given name. Comparison is case-insensitive.

@param [Array<Bindings::Binding>] bindings the bindings to find in @param [String] name the name of the binding to find @return [Bindings::Binding] the binding with a given name if it exists @return [nil]

# File lib/bindings.rb, line 65
def self.find(bindings, name)
  bindings.each do |b|
    return b if b.name.casecmp?(name)
  end

  nil
end

Creates a new collection of Bindings::Binding's using the specified root. If the directory does not exist, an empty collection is returned.

@param [String] root the root to populate the bindings from @return [Array<Bindings::Binding>] the bindings found in the root

# File lib/bindings.rb, line 40
def self.from_path(root)
  return [] unless File.exist?(root) && File.directory?(root)

  Pathname.new(root).children.each_with_object([]) do |c, b|
    b.append(ConfigTreeBinding.new(c.to_s)) if File.directory?(c)
  end
end

Creates a new collection of Bindings::Binding's using the +$SERVICE_BINDING_ROOT+ environment variable to determine system root. If the +$SERVICE_BINDING_ROOT+ environment variable is not set, an empty collection is returned. If the directory does not exist, an empty collection is returned.

@return [Array<Bindings::Binding>] the bindings found in $SERVICE_BINDING_ROOT

# File lib/bindings.rb, line 53
def self.from_service_binding_root
  return [] unless ENV.key?(SERVICE_BINDING_ROOT)

  from_path(ENV[SERVICE_BINDING_ROOT])
end

Tests whether a String is a valid Kubernetes Secret key: kubernetes.io/docs/concepts/configuration/secret/#overview-of-secrets

@param [String] key the key to check @return [boolean] true if the String is a valid Kubernetes Secret key, false otherwise

# File lib/secret.rb, line 26
def self.valid_secret_key?(key)
  /^[A-Za-z0-9\-_.]+$/.match(key)
end
