[Unreleased] - [Git compare]

Added

  • [Issue #300] Set timeout on a function Functions can now be declared with a timeout using the timeout flag. This timeout is used internally to set a deadline time for function execution. If a function invocation reaches the function server after the deadline has expired the function will not be invoked. Otherwise the function will be invoked until the function returns or the deadline is hit, whichever comes first. This support requires the use of the most recent function base images, 0.0.11 for nodejs-base and python3-base and 0.0.12 for java-base and powershell-base. Executing dispatch create seed-images will automatically populate these images.

Fixed

Removed

[0.1.22] - 2018-07-18 [Git compare]

Fixed

  • Fix dispatch uninstall cmd ignoring config file dispatch uninstall cmd was ignoring the namespace definition in the config file. This patch fixes it and adds some unit test as the command is broken more often than not.
  • Bump version of PhotonOS in our images An ancient version of PhotonOS image was used. Updated to vmware/photon2:20180620.

Removed

  • Move source code out of function entity Function entity used to hold the .tar.gz archive of the source code folder (or file) from which the function was built.

[0.1.21] - 2018-07-10 [Git compare]

Added

  • [Issue #518] Single-binary, local version of Dispatch Server: This release includes a single-binary dispatch-server. You can run this server locally on your desktop without a need to provision Kubernetes - the only requirement is Docker. This should cover use cases like local development, proofs of concept, or a small deployment for personal needs. To use it, simply download the dispatch-server binary for your platform, and run dispatch-server local.

    Note: The local version supports all commands/resources except:

    • event drivers
    • services

  • Add Org to bulk create CLI Orgs can now be defined in yaml files and populated in Dispatch using dispatch create -f seed.yaml

  • Ingress class option Use this option to target a different ingress controller

Fixed

  • Fixed entity store bug Fixed a bug where the libkv-based entity store would return entities of different types if they shared the same prefix
  • Fixed chart issue Fixed an issue where the resources specified for an individual sub-chart didn't take precedence over the global resources

Removed

[0.1.20] - 2018-07-03 - [Git compare]

Added

  • [Issue #465] Tail/follow function runs as they happen. When retrieving runs you can now specify the --last flag to get the latest executed run. You can also now specify the --follow or -f flag to follow/tail runs as they occur. PR #537

  • API Gateway endpoints now namespaced with the org name Creates the user-specified API paths under the org name. This is because we share an API Gateway and the paths from different org's can overlap. For production uses, user usually specifies a hostname for the API's.

Fixed

[0.1.19] - 2018-06-26 [Git compare] [What's new]

Added

  • Enable Exposed Event Drivers Events may now be pushed (as opposed to pulled) from event sources to Dispatch. An exposed driver will create an ingress route and service to recieve events.

[0.1.18] - 2018-06-19 [Git compare] [What's new]

Fixed

  • Limited Multi-Tenancy Support. Dispatch now supports multi-tenancy with the ability to create multiple organizations and define policies to gives access to users on those organizations. This is a limited functionality and does not isolate the function execution environments within the underlying FaaS engine or define network policies for the function pods running on Kubernetes.PR #510 PR #529.
  • Fix single file Java support. Previously Java would fail for single files if no handler argument is provided. PR #517
  • [Issue #483] No helpful error output when an error occurs during function create. Added a reason field to the function object to hold function creation errors. PR #513

[0.1.17] - 2018-06-12 - [Git compare] [What's new]

Added

  • Improved IAM bootstrap workflow. New CLI Command dispatch manage bootstrap to automatically bootstrap Dispatch with a new organization, service account and policies upon installation. This replaces the dispatch manage --enable-bootstrap-mode command that required the user to manually enter the bootstrap mode to create the authorization accounts and policies. PR #501.
  • New CLI Command to print the versions. A New CLI Command dispatch version to print the client and server versions has been introduced. As part of this change a new /v1/version API has been added to the Identity Manager service that returns the current server version. The client version is embedded into the dispatch binary. PR #500.
  • New CLI command to create seed images. A New CLI Command dispatch create seed-images to create base-images and images of commonly used languages in the dispatch community. The revision of the created base-images/images corresponds to that of the CLI's. PR #507

Fixed

  • [Issue #251] Deleting image deletes its base-image if they have the same name. Previously when deleting an image with the same name as a base-image, the base-image would also be deleted at the same time. It's fixed now. PR #504.

[0.1.16] - 2018-06-06 - [Git compare] [What's new]

Added

  • [BREAKING CHANGE] Support for contexts when working with Dispatch CLI. Dispatch config files now have contexts, allowing user to work with multiple instances of Dispatch at the same time. This change requires config file to be context-aware (old version of config won't work with new CLI). PR #478.
  • Initial support for function timeout. When creating a function, user can now specify a timeout (in milliseconds). When executing a function, it will be terminated if takes longer than the specified timeout. Note that this is language-dependent (language pack must support timeout). PR #487.
  • CLI login now works with service accounts. Previously, dispatch login command only worked with OIDC users (e.g. when authentication has been configured using GitHub auth provider). Now you can run dispatch login --service-account test-svc-account --jwt-private-key <path-to-key-file> and the auth data will be stored in the dispatch config file. there is also a corresponding dispatch logout command to clear the credentials. PR #460.
  • Batch resource creation now supports all resource types. One of the handy features of Dispatch CLI is batch creation of resources, where user can specify multiple resources using YAML file, and then create them all using dispatch create -f file.yaml command. In this release, the batch file supports all resource types (previously event drivers, driver types, event subscriptions and APIs were missing). PR #495.

Fixed

  • [Issue #472] Send empty response in API gateway when function does not return anything. Previously, API gateway would return a complete output of function execution from function manager if function itself didn't return any content. This exposed a lot of arguably private information about the internal implementation of the function. From now on, the API gateway will return an empty response if function output is null. PR #477.
  • [Issue #486] Event Driver creation failed when secrets were used. Previous release introduced a regression in event driver creation if driver was configured with secrets. It's now fixed. PR #488.
  • [Issue #485] Dispatch resources displayed incorrect timestamps. The timestamps for Dispatch resources (functions, images, etc.) displayed incorrect dates, i.e. dates that did not correspond to the actual dates of creation/modification of resources. In this release, the dates should now be properly saved and displayed. NOTE: due the nature of this bug, only new deployments will notice the fix. PR #494.

[0.1.15] - 2018-05-24 - [Git compare] [What's new]

Added

  • New function manager backend using Kubeless. You can now run your functions in Dispatch using Kubeless (many thanks to Andres for the contribution). Set the faas option to kubeless in your install config to deploy Dispatch with kubeless. More examples with Kubeless coming soon.
  • Support for providing entire directory instead of single file when creating a function. You can now specify a directory instead of single file when creating a function. See [What's new in v0.1.15] for more details on using this feature. PRs #470, #474.
  • New CLI command dispatch log to print service logs. Previously, to check logs of any of dispatch services, one had to find the name of the Kubernetes Pod corresponding to the service, and use kubectl to grab the logs. With this change, getting logs for function manager is as simple as running dispatch log function-manager (similar for other services). It supports the follow mode (-f) as well! PR #445.
  • Support for HTTPS via Let's Encrypt and Cert Manager. API gateway can now be exposed using a hostname with a valid, signed certificate, courtesy of Let's Encrypt. For details, see the PR #427.
  • Improved support for Tracing. Dispatch now propagates tracing context within services, resulting in better view of code involved in handling the request. PR #461.

Changed

  • Improved handling of function execution errors. Functions can now return different errors when execution fails, depending on when and why the error happened. See Error handling specification for more details. PRs #423, #424.

Fixed

  • Gopkg.toml is configured to prune unused dependency files. Previously, after running dep ensure, one had to use separate prune command to clean the vendor directory. Now the prunning is done as a part of dep ensure. This change should make it easier for contributors to add new dependencies. PR #441.
  • Dispatch services now use flattened swagger spec. Previously, spec had to be flattened as an extra step during spec generation. This change should make the make generate step much shorter. PR #443.
  • Dispatch built-in vcenter event driver now properly reads environment variables. PR #456.

[0.1.14] - 2018-05-15 - [Git compare]

Added

  • Support for private image registries that require auth for pulling (OpenFaaS only). Dispatch can now properly when using external private registry that requires credentials when pulling an image. This feature is only available when using OpenFaaS backend. PR #438.

Fixed

  • Improved IAM documentation. Bootstrap mode and service account management should now be clearer. PR #425.
