API Reference

This documentation describes the functionality that is available for configuration authors.

Documentation describing the functionality and schema of configuration (workflow, bootstrap etc.) is referred to as the model and is available below.

Documentation describing the functionality and schema of the testing harness is available below.

opscotch configuration model​

The opscotch model is relatively straight forward, and uses repeated patterns - once you grasp these you should be able to understand the entire structure.

Here is the outline of the entire structure of the two configurations: the bootstrap and the workflow. Note that not every field is required, so be sure to check the detailed descriptions.

Bootstrap JSON Schemas​

JSON Schema in the Bootstrap Package:

Bootstrap​

A configuration that is loaded into the agent at startup and determines how the agent loads the main configuration is loaded.

Please note that the bootstap file that is authored is an ARRAY of these objects ie:

[
      {
          "agentPrivateKey": ...
          "deploymentId": ...
      }
]

It will be provided to the agent as an argument, either via a base64 encoded json text or a path to a json file

JSON Properties​

The following properties are available to set on the JSON schema.

agentPrivateKey​

Type: String

Required The private key for the agent to decrypt the remote configuration.

This should be a base64 encoded private key in pkcs8 format

This is how to create an appropriate key

1. Create key pair
openssl genrsa -out keypair.pem 2048

2. Extract public part
openssl rsa -in keypair.pem -pubout -out public.key

3. Extract private part
openssl pkcs8 -topk8 -inform PEM -outform PEM -nocrypt -in keypair.pem -out private.key

4. Base64 the contents of this file
cat private.key | base64
{
  "agentPrivateKey": "LS0tLS1CRUdJTiBQUklWQV...."
}

This property is required

Step​

The Step is the primary configuration item for the agent configuration.

This configuration describes how to perform a single step or action in a Workflow.

There are different types of steps, however they all have the same execution structure:

  • Prepare
  • Execute
  • Process

Steps take three forms of input:

  • The response from a call to a Host (context.getMessageBodyAsString())
  • The message passed from another Step (context.getPassedMessageAsString())
  • Data from the configuration (context.getData())

The different types of Steps allow for specialised behaviour:

  • "scripted" type: this is the default type with the following flow:

    1. Optionally generate a URL (urlGenerator)

    2. Optionally (requires a url to have been set) generate a payload (payloadGenerator)

    3. Optionally perform authentication steps (authenticationProcessor, call other steps to perform authentication)

    4. Optionally call out to a named Bootstrap Host with the generated URL and payload

    5. Optionally handle specific HTTP status codes with httpStatusHandling

      OR

    6. Process the response or perform after-call processing (resultsProcessor)

      Perhaps:

      • Send a message to another Step
      • Produce some metrics

  • "scripted-split-aggregate" type: this is a modified "scripted" type that has the following workflow of:

    1. transforming the input into a list (splitGenerator)

    2. calling a URL with each item in the list:

      1. Optionally generate a URL (urlGenerator)

      2. Optionally (requires a URL to have been set) generate a payload (payloadGenerator)

      3. Optionally perform authentication steps (authenticationProcessor, call other steps to perform authentication)

      4. Optionally call out to a named Bootstrap Host with the generated URL and payload

      5. Optionally handle specific HTTP status codes with httpStatusHandling

        OR

      6. Optionally Process each item's response (itemResultProcessor)

      7. Collect the result into a response list

    3. The list of collected responses can then be processed and per normal (resultsProcessor)

      Perhaps:

      • Send a message to another Step
      • Produce some metrics

      Please note that in the case that one of the HTTP requests fail, it is your responsibility to handle this case by using the httpStatusHandling, itemResultProcessor, and resultsProcessor

  • "scripted-auth" type: this is identical to "scripted" except that it has an alternative javascript context - it is not allowed to send metrics or call to non-authentication steps, but has access to the bootstrap data which may contain secrets.

  • "httpFile" type: this is a specialized step that serve static content from a zip file by mapping a url path into a zip file path. This type REQUIRES a http trigger to be defined, an only allows GET requests

At least one step in a Workflow will define a Step.trigger that will trigger the start of Workflow processing.

These forms of input and different type allows for the construction of flexible pipelines that should be sufficient to perform most tasks.

Opscotch Error Codes​

Many errors will have an Opscotch Error Code that may be referenced in logs, metrics or messages. Please see the list below for descriptions of error codes:

AJC1: Can not decrypt encrypted data​

This error occurs when the host data property accessed in an authentication context contains encrypted data but failed to decrypt.

Check that the encrypted data is complete. Check that the data was encrypted with a compatible packaging tool version. Check that the matching bootstrap agentPrivateKey public key was used for encryption.

BL1: Failed to load bootstrap​

This is a generic error code that indicates that the specific individual bootstrap failed to load.

Check the error message for additional Opscotch Error Codes

BL2: Duplicate deploymentId​

This error occurs when a bootstrap is loaded with a deploymentId that is already loaded.

Check the bootstrap file for duplicated deploymentId properties.

BL3: Failed to load bootstrap - Decryption​

This is a generic error code that indicates that the specific individual bootstrap failed to decrypting using the internal opscotch keys.

Check that the version of the packaging tool matches the opscotch agent.

BS1: Malformed url​

This error occurs when the url specified in a Output.outputUrl is malformed.

Check the outputUrl property is correct.

BS2: Failed send for metrics or logs​

This error occurs during an unexpected operation. The data you were trying to send has likely been lost.

Please contact opscotch to report the fault.

CD1: The agent private key is invalid​

The agentPrivateKey was read and Base64 decoded from the bootstrap record, but could not read as an RSA PKCS8 private key.

Check that the bootstrap agentPrivateKey is a Base64 encoded private key in pkcs8 format

CD2: Encoding versions do not match​

This error occurs when the Workflow configuration is packaged with an old packaging tool version.

Check that the version of the packaging tool matches the opscotch agent.

CD3: Could not decrypt config​

This error code occurs when the Workflow configuration can not be decrypted.

Check that the matching public and private keys are used. Check that the version of the packaging tool matches the opscotch agent. Check that you're deploying the intended Workflow configuration to the correct agent.

CD4: Workflow JSON file format is not supported​

This error occurs when attempting to load a raw workflow json file.

Ensure that the bootstrap remoteConfiguration property refers to a packaged workflow configuration.

CDE1: Workflow Configuration not loaded​

This error occurs when the Workflow configuration signature can not be validated, even after decryption.

This implies that the content of the encrypted Workflow configuration was manipulated before encryption. This is a very strange state and you should contact opscotch immediately.

CP1:​

This is a generic error that occurs when the Workflow configuration fails to load.

Please see additional messages

CP2:​

This is a generic error that occurs when the Workflow configuration fails to load.

Please see additional messages

CP3: Invalid agentPrivateKey in bootstrap​

This error occurs when the Base64 decode of the bootstrap agentPrivateKey property fails.

Ensure that the bootstrap agentPrivateKey property is a Base64 encoded string

CP4: agentPrivateKey is required in bootstrap in Prod Mode​

This error occurs when running in Prod Mode and the bootstrap agentPrivateKey property is missing.

Ensure that the bootstrap agentPrivateKey property is a Base64 encoded string

CR1: Failed loading configuration​

This is a generic error that occurs after json validation when trying to load the steps.

Please see additional messages.

CR2: Step requested does not exist​

This occurs when the requested step has not been loaded.

Step requested does not exist

CR3: Workflow did not finish active runs in time. Forcing reload​

This occurs during a workflow configuration reload, due to a configuration change when there were workflows executing when the reload was triggered, and the running workflows had not completed within the reload timeout. The reload occured regardless and this might have resulted in two versions of the workflow running for a period of time.

To prevent this happening, increase the reloadTimeout in the bootstrap.

CRW1: Exception while checking license​

This error occurs when there is a problem with the license checking mechanism.

Please see additional messages and contact opscotch if necessary.

CW1: Malformed url​

The Url specified in the bootstrap remoteConfiguration is an invalid Url.
