`class CommandError`

Raised when a kubectl command fails.

begin resource.patch rescue Kube::CommandError => e e.subcommand # => "patch" e.stderr # => "Error from server (NotFound): ..." e.exit_code # => 1 e.reason # => "NotFound" (parsed from stderr, or nil) end

Definitions

`def parse_reason(stderr)`

Attempts to extract the reason from kubectl stderr. kubectl errors typically look like: Error from server (NotFound): deployments.apps "foo" not found Error from server (Forbidden): ... error: the server doesn't have a resource type "foo"

Implementation

def parse_reason(stderr)
  return nil if stderr.nil? || stderr.empty?

  if stderr =~ /\((\w+)\)/
    $1
  end
end
