Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

This class implements a state machine for bootstrapping a host’s CA and CRL bundles, private key and signed client certificate. Each state has a frozen SSLContext that it uses to make network connections. If a state makes progress bootstrapping the host, then the state will generate a new frozen SSLContext and pass that to the next state. For example, the NeedCACerts state will load or download a CA bundle, and generate a new SSLContext containing those CA certs. This way we’re sure about which SSLContext is being used during any phase of the bootstrapping process.

Constructor Details

#initialize(waitforcert: , maxwaitforcert: , waitforlock: , maxwaitforlock: , onetime: , cert_provider: Puppet::X509::CertProvider.new, ssl_provider: Puppet::SSL::SSLProvider.new, lockfile: Puppet::Util::Pidlock.new(Puppet[:ssl_lockfile]), digest: 'SHA256', ca_fingerprint: ) ⇒ StateMachine

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Construct a state machine to manage the SSL initialization process. By default, if the state machine encounters an exception, it will log the exception and wait for ‘waitforcert` seconds and retry, restarting from the beginning of the state machine.

However, if ‘onetime` is true, then the state machine will raise the first error it encounters, instead of waiting. Otherwise, if `waitforcert` is 0, then then state machine will exit instead of wait.

Parameters:

  • waitforcert (Integer) (defaults to: ) —

    how many seconds to wait between attempts

  • maxwaitforcert (Integer) (defaults to: ) —

    maximum amount of seconds to wait for the server to sign the certificate request

  • waitforlock (Integer) (defaults to: ) —

    how many seconds to wait between attempts for acquiring the ssl lock

  • maxwaitforlock (Integer) (defaults to: ) —

    maximum amount of seconds to wait for an already running process to release the ssl lock

  • onetime (Boolean) (defaults to: ) —

    whether to run onetime

  • lockfile (Puppet::Util::Pidlock) (defaults to: Puppet::Util::Pidlock.new(Puppet[:ssl_lockfile])) —

    lockfile to protect against concurrent modification by multiple processes

  • cert_provider (Puppet::X509::CertProvider) (defaults to: Puppet::X509::CertProvider.new) —

    cert provider to use to load and save X509 objects.

  • ssl_provider (Puppet::SSL::SSLProvider) (defaults to: Puppet::SSL::SSLProvider.new) —

    ssl provider to use to construct ssl contexts.

  • digest (String) (defaults to: 'SHA256') —

    digest algorithm to use for certificate fingerprinting

  • ca_fingerprint (String) (defaults to: ) —

    optional fingerprint to verify the downloaded CA bundle
