Configuration

Configuration is done via a yaml file. The default location is ~/.config/.pubtools-sign/conf.yaml or /etc/pubtools-sign/conf.yaml. You can also specify a custom location via the –config argument. The configuration file is divided into sections, each section is a signer. Each signer has a set of attributes that are used to configure the signer Conf.yaml has following structure::

msg_signer:
  messaging_brokers:
    - <protocol://<host>:<port> for messaging broker
  messaging_cert_key: <path to messaging client key + certificate in PEM format>
  messaging_ca_cert: <path to CA certificate bundle>
  topic_send_to: topic://<topic> - topic where to send signing requests
  topic_listen_to: queue://<queue> - queue where to listen for answers from signing server. Supported templating variables: {creator - UID from client cert}, {task_id}
  environment: <env> - environment attribute which is included in signing request
  service: <service> - service attribute which is included in signing request
  timeout: <int> - timeout for signing request
  retries: <int> - number of retries for receiving signing responses from messaging brokers
  send_retries: <int> - number of retries for whole send + receive cycle
  message_id_key: <id> - attribute in message response used as unique identifier for signing request
  log_level: <level> - log level for pubtools-sign
cosign_signer:
  rekor_url: <rekor-url>
  upload_tlog: <true|false>
  registry_user: <user> - used to login to registry where images will be signed
  registry_password: <password>
  env_variables:
    <key>: <val> - mapping of environment variables used in signing process. This can be used for example for AWS setup
  key_aliases:
    <alias>: <key> - mapping of key aliases to actual keys. When passing alias as signing key, <key> is used instead. This
                     way you cna define for example "prod-key" alias and have different real keys for different signers
