channel_block – Fetch blocks for a Hyperledger Fabric channel
Synopsis
Fetch blocks for a Hyperledger Fabric channel.
This module works with the IBM Support for Hyperledger Fabric software or the Hyperledger Fabric Open Source Stack running in a Red Hat OpenShift or Kubernetes cluster.
Parameters
- api_endpoint (required)
The URL for the Fabric operations console.
Type: str- api_authtype (required)
basic- Authenticate to the Fabric operations console using basic authentication. You must provide both a valid API key using api_key and API secret using api_secret.Type: str- api_key (required)
The API key for the Fabric operations console.
Type: str- api_secret
The API secret for the Fabric operations console.
Only required when api_authtype is
basic.Type: str- api_timeout
The timeout, in seconds, to use when interacting with the Fabric operations console.
Type: intDefault value:60- state
absent- If a block exists at the specified path, it will be removed.
present- Fetch the block from the specified channel and store it at the specified path.Type: strDefault value:present- ordering_service (required)
The ordering service to use to manage the channel.
You can pass a string, which is the cluster name of a ordering service registered with the Fabric operations console.
You can also pass a list, which must match the result format of one of the ERROR while parsing: While parsing “M(ordering_service_info)” at index 76: Module name “ordering_service_info” is not a FQCN or ERROR while parsing: While parsing “M(ordering_service)” at index 104: Module name “ordering_service” is not a FQCN modules.
Only required when operation is
fetch.Cannot be specified with ordering_service_nodes.
Type: raw- ordering_service_nodes
The ordering service nodes to use to manage the channel.
You can pass strings, which are the names of ordering service nodes that are registered with the Fabric operations console.
You can also pass a dict, which must match the result format of one of the ERROR while parsing: While parsing “M(ordering_service_node_info)” at index 76: Module name “ordering_service_node_info” is not a FQCN or ERROR while parsing: While parsing “M(ordering_service_node)” at index 109: Module name “ordering_service_node” is not a FQCN modules.
Only required when operation is
fetch.Cannot be specified with ordering_service.
Type: raw- identity (required)
The identity to use when interacting with the ordering service or for signing channel configuration update transactions.
You can pass a string, which is the path to the JSON file where the enrolled identity is stored.
You can also pass a dict, which must match the result format of one of the ERROR while parsing: While parsing “M(enrolled_identity_info)” at index 76: Module name “enrolled_identity_info” is not a FQCN or ERROR while parsing: While parsing “M(enrolled_identity)” at index 105: Module name “enrolled_identity” is not a FQCN modules.
Type: raw- msp_id (required)
The MSP ID to use for interacting with the ordering service or for signing channel configuration update transactions.
Type: str- hsm
The PKCS #11 compliant HSM configuration to use for digital signatures.
Only required if the identity specified in identity was enrolled using an HSM.
Type: dict
- pkcs11library
The PKCS #11 library that should be used for digital signatures.
Type: str- label
The HSM label that should be used for digital signatures.
Type: str- pin
The HSM pin that should be used for digital signatures.
Type: str- name (required)
The name of the channel.
Type: str- target (required)
The target block to fetch.
Can be the number of the block to fetch, or one of
newest,oldestorconfig.Type: str- path (required)
The path to the file where the channel configuration or the channel configuration update transaction will be stored.
Type: str- tls_handshake_time_shift
The amount of time to shift backwards for certificate expiration checks during TLS handshakes with the ordering service endpoint.
Only use this option if the ordering service TLS certificates have expired.
The value must be a duration, for example 30m, 24h, or 6h30m.
Type: str
