Latest - August 4, 2023, Harness version 80120, Harness Delegate version 80104​

Harness NextGen release 80120 includes the following changes for the Harness Delegate.

Deprecation notices​

Helm 2

To safeguard your operations and protect against potential security vulnerabilities, Harness will launch an update to deprecate the Helm 2 binary from delegates with an immutable image type (image tag yy.mm.xxxxx) later this month. For information on delegate types, go to Delegate image types.

Helm 2 was deprecated by the Helm community in November 2020 and is no longer supported by Helm. If you continue to maintain the Helm 2 binary on your delegate, it might introduce high and critical vulnerabilities and put your infrastructure at risk.

If your delegate is set to auto-upgrade, Harness will automatically remove the binary from your delegate. This will result in pipeline and workflow failures for services deployed via Helm 2.

note

If your development team still uses Helm 2, you can reintroduce the binary on the delegate. Harness is not responsible for any vulnerabilities or risks that might result from reintroducing the Helm 2 binary.

For more information about updating your delegates to reintroduce Helm 2, go to:

Contact Harness Support if you have any questions.

Kustomize 3.4.5

To safeguard your operations and protect against potential security vulnerabilities, Harness will launch an update to deprecate the Kustomize 3.4.5 binary from delegates with an immutable image type (image tag yy.mm.xxxxx) on September 30, 2023. For information on delegate types, go to Delegate image types.

In place of Kustomize, Harness will use the kubectl binary to conduct Kustomize operations. Recent enhancements (versions 1.14 and higher) have made the kubectl binary fully capable of supporting Kustomize operations. For more information, go to Kustomization in the Kubernetes documentation.

If your delegate is set to auto-upgrade, Harness will automatically remove the binary from your delegate. This will result in pipeline and workflow failures for services that use Kustomize 3.4.5.

note

If your development team still uses Kustomize 3.4.5, you can reintroduce the binary on the delegate. Harness is not responsible for any vulnerabilities or risks that might result from reintroducing the Kustomize 3.4.5 binary.

For more information about updating your delegates to reintroduce Kustomize 3.4.5, go to:

Contact Harness Support if you have any questions.

  • Removed Helm version 3.1 from from delegates with an immutable image type (image tag yy.mm.xxxxx). (CDS-58892, ZD-47520, ZD-48553)

    For information on delegate types, go to Delegate image types.

  • Upgraded go-template binary to version 0.4.3, which uses Go version 1.20. (CDS-58919)

  • Upgraded the Helm binary from version 3.8 to 3.12. (CDS-58931)

  • The kubectl command now includes retry logic to handle connection issues. (CDS-72869)

  • The Execution Logs have been enhanced to include additional details such as duration, task ID, and more. These details help you understand and debug CV Steps, SRM Live monitoring, and SLI. (OIP-565)

  • In manual Query mode, the Datadog Metrics Health source now provides support for formulas. (OIP-568)

    These formulas follow a specific format: Query a ; Query b ; Formula using a, b.

    Let's consider an example to illustrate this:

    • Query a is "Query-with-a"

    • Query b is "Query-with-a"

    • The formula is "(a/b) * 100 - 5"

      The resulting query would appear as follows: kubernetes.memory.usage{cluster-name:chi-play};kubernetes.memory.total{cluster-name:chi-play};(a/b) * 100 - 5

      In the above example, a and b represent the respective queries:

    • a = kubernetes.memory.usage{cluster-name:chi-play}

    • b = kubernetes.memory.total{cluster-name:chi-play}

      You can include any number of queries in the final formula using alphabetical variables, such as a, b, c, d, and so on.

  • Error messages from health source providers are now included in API responses for improved user experience and debugging efficiency. (OIP-657)

  • A new getAzureKeyVaultClient API is available to fetch the list of Azure vaults. This option reduces the time it takes for Harness to reflect a newly-created Azure vault. (PL-28392, ZD-44045)

July 20, 2023 Harness Delegate hotfix version 79906​

  • Helm deployment steps timed out after the initial installation/upgrade phase, preventing the execution of a Helm rollback step. (CDS-73264)

    This issue is now fixed.

July 18, 2023, Harness version 79916, Harness Delegate version 79904​

Harness NextGen release 79916 includes the following changes for the Harness Delegate.

What's new​

  • The Splunk connector has been enhanced to include support for Bearer Token. (OIP-598)

  • The List Tokens API now supports listing all the personal access tokens or service account tokens in the account. The API has been enhanced as follows:

    1. If you have user management permissions, you can list all the Personal Access Tokens in your account. You can also filter tokens belonging to a user or filter only active tokens.
    2. If you have service account management permissions, you can list all the service account tokens in your account. You can also filter tokens for a service account or filter only active tokens. (PL-31870, ZD-40110)
Early access​

  • Harness added the ability to acquire only the configured maximum number of tasks. This allows Harness Manager to use the task capacity to determine whether to assign a task to the delegate or queue it. You can configure the maximum number of tasks using the Env variable DELEGATE_TASK_CAPACITY. For example, if you set DELEGATE_TASK_CAPACITY to a value of 2 and execute 6 tasks in parallel, Harness Manager executes only 2 tasks at a time. If you don't configure DELEGATE_TASK_CAPACITY, Harness Manager executes all 6 tasks in parallel. (PL-39351)

    This functionality is behind a feature flag, DELEGATE_TASK_CAPACITY_CHECK. When the feature flag is enabled, the task is broadcast every minute in Harness Manager until it expires.

Fixed issues​

  • Cron triggers artifact setting failed when modified regex did not match any build. (CDS-72589, ZD-46323)

    Harness initially modifies the regex to see if it matches any build. The trigger was failing if it did not match. Now, if the regex does not match any build, Harness will use the original regex.

  • Artifactory artifact source Artifact Name regex value was not working correctly. (CDS-73150)

    Harness has added support for regex values for generic type Artifactory artifacts.

  • The sort order on the pipelines list page was incorrect. (CDS-73216)

    Now, Harness supports case-insensitive sorting for pipelines, input sets, and pipeline executions.

  • The <+configFile.getAsBase64()> expression not resolving correctly when the content had new lines. (CDS-73424)

    The issue occurred with newline characters while encoding config files. This is fixed and Harness now replaces newline characters with unicode.

  • There was an error collecting metric data when encountering null values returned by metric queries. (OIP-551)

    This issue has been resolved by ignoring null data points and using valid data points in the window.

  • The Tokens list page returned a display error when tokens were present and there were multiple pages of results. (PL-36734)

    A code enhancement to reset the pagination on the Tokens list page after any token is deleted fixed this issue. Previously, if you deleted the last token on any page after the first page, the page displayed an empty result list.

  • The listDelegates API failed when custom selectors were present in the delegate. (PL-39779)

    A code enhancement to update custom tags fixed this issue.

  • The listing API failed with an UnsupportedOperationException when custom tags were present. Filter APIs failed with NPEs. (PL-39824)

    A code enhancement fixed these issues.

  • The delegate token list result from the DelegateTokenStatus API endpoint displayed all values as null. (PL-39440)

    A code enhancement for the DelegateTokenStatus endpoint to return token values even when token details are not fetched by token name fixed this issue. Token values only populate when the user has edit delegate permission. If the user doesn't have edit delegate permission, the value remains null.

  • The AWS connector widget's prefix field did not accept prefixes starting with a slash. Such slashes were stripped off, and this led to undesired behavior. (PL-39194, ZD-45104)

    Prefixes that begin with a slash are now supported.

  • You could not create Azure Key Vault connectors in Harness NextGen even when you used the service principal credentials that successfully created Azure Key Vault connectors in Harness FirstGen. After you entered the service principal credentials, the Vault setup window stopped responding. After several minutes, the following message is displayed: None of the active delegates were available to complete the task. ==> : 'Missing capabilities: [https:null.vault.azure.net]' (PL-39783, ZD-46756)

    This issue is now fixed.

June 28, 2023, Harness version 79714, Harness Delegate version 79707​

Harness NextGen release 79714 includes the following changes for the Harness Delegate.

What's new​

  • You can now see disconnected delegate details in selection logs and error messages when there are no eligible delegates in an active state to execute tasks. (PL-37900)

  • The delegate JRE is upgraded to 11.0.19_7. (PL-37994)

  • When a delegate token is revoked, Harness now sends SELF_DESTRUCT to all delegates that are using the revoked token. (PL-38957)

Early access​

  • Added a new field in the release history for Blue Green deployments to differentiate between environments. (CDS-69961)

    Enable the feature flag, CDS_BG_STAGE_SCALE_DOWN_STEP_NG to leverage this feature.

    This is an enhancement to the Kubernetes Blue Green Stage Scale Down step. You can now scale down your last successful stage environment only if the primary resources exist. This enhancement helps you efficiently manage your resources, and prevent deleting the important resources.

    Make sure that the infrastructure definition of these resources and the Blue Green service are the same. This is necessary as Harness identifies resources from the release history, which is mapped to a release name. If you configure a different infrastructure definition, it might lead to scaling down important resources.

Fixed issues​

  • A project-level template crashed when opened. (CDS-71980, ZD-45950)

    The three hyphens, --- used in the YAML as YAML document separator was being replaced by ---\n with an empty string due to a logic in the code. This logic made the YAML invalid.

    This issue is fixed by disabling YAMLGenerator.Feature.WRITE_DOC_START_MARKER in the YamlUtils to stop the YAML document separator --- from being added to the YAML.

  • Fixed an issue where the applications created outside Harness were deleted during rollback if a Tanzu Application Services (TAS) Rolling deployment failed the first time. (CDS-71397)

  • Pipeline execution failed when a variable whose required field is set to TRUE is passed as an expression. (CDS-71357, ZD-45615)

    Harness checks for the value of the variable whose required field is set to TRUE, and the pipeline failed if the value was empty. This issue occurred when Harness checked for the value of variables that were passed as expressions. The value of expressions cannot be resolved during pipeline creation.

    This issue is fixed by ignoring the check for variables passed as an expression.

  • Creating a launch template for an AWS Auto Scale Group (ASG) deployment resulted in a null pointer exception. (CDS-71235)

    This issue is fixed by adding proper validation for the ASG launch template manifest content.

  • Improved the error message for pipeline execution failures when running a pipeline that has nested chained pipelines. (CDS-69578, ZD-44443)

  • CloudFormation deployment failed with an unclear error message, # Exception: Invalid request: Template format error: YAML not well-formed. (line 1, column 40) (Service: AmazonCloudFormation; Status Code: 400; Error Code: ValidationError; Request ID: 7685da0b-c14a-47e2-afe5-9e4ffde536c6; Proxy: null) while Updating stack: pipeline-demo.. (CDS-68866, ZD-44165)

    When a multi-line string was passed as input for a child pipeline, the string was being converted to a single line.

    This issue is fixed. Instead of passing data using YAML, Harness now uses JSON for data processing. This helps preserve multi-line strings and YAML structures properly to process pipeline YAML and user inputs. Enable the feature flag, PIE_PROCESS_ON_JSON_NODE to leverage this fix.

  • Fixed an issue where the expression, <+lastPublished.tag>.regex() was not resolved properly when used as runtime input for artifacts. (CDS-68810)

  • Quotations were added to execution YAML strings inconsistently when comparing pipeline YAMLs. (CDS-67637)

    This issue is fixed by enabling MINIMIZE_QUOTES for YamlUtils and YamlPipelineUtils classes. The compiled YAML no longer has quotations around strings where they are not needed, but only around numbers. Even if you had added quotations in the string values in the pipeline YAML, they'll be removed in the compiled YAML. Also, there won't be unnecessary audit trails where the diff only has quotations around strings.

  • Account-level connectors with resource groups set to Specified were not available at the project-level. (PL-38828)

    This issue is now fixed. The connectors list shows the connectors for which users have resource group permissions set.

  • The account-level Session Timeout (in minutes) allowed values greater than the 4320 minute maximum. (PL-32498)

    This issue has been resolved by adding a code validation. The field no longer accepts values above 4320 minutes.

June 9, 2023, Harness version 79516, Harness Delegate version 79503​

Harness NextGen release 79516 includes the following changes for the Harness Delegate.

What's new​

  • Send emails to non-Harness users. (CDS-58625, ZD-42496)

    To send emails to non-Harness users, you must configure your own SMTP server and enable the Enable Emails to be sent to non-Harness Users default setting. This setting is available at Account, Org, and Project levels.

    For more information on how to send emails to non-Harness users, go to Email step reference.

  • Converted Harness CD from an explicit to an implicit change source for Service Reliability Management. (SRM-14724)

Early access​

  • Scale down the last successful stage environment created by using a Blue Green Deployment strategy. (CDS-68527)

    This functionality is behind a feature flag, CDS_BG_STAGE_SCALE_DOWN_STEP_NG.

    This functionality helps you efficiently manage your resources. The scale down step can be configured within the same stage or different stage based on your requirement.

    During scale down, the HorizontalPodAutoscaler and PodDisruptionBudget resources are removed, and the Deployments, StatefulSets, DaemonSets and Deployment Configs resources are scaled down. Make sure that the infrastructure definition of these resources and the Blue Green service are the same. This is necessary as Harness identifies resources from the release history, which is mapped to a release name. If you configure a different infrastructure definition, it might lead to scaling down important resources.

  • Kubernetes deployments support HorizontalPodAutoscaler and PodDisruptionBudget for Blue Green and Canary execution strategies. (CDS-59011)

    This functionality is behind a feature flag, CDS_SUPPORT_HPA_AND_PDB_NG.

Fixed issues​

  • Enhanced handling and logging for the No enum constant io.harness.delegate.message.MessengerType.WATCHEIN exception to enable the actual malformed message. This error indicates that a message is malformed and only occurs when there is an error during writing, for example, out of disk, process killed, etc. (PL-38245)

  • Unable to create SLO using SignalFX metrics. (OIP-406)

    This issue has been resolved. Now, SignalFX's health source supports SLI functionality, and you can create SLOs using SignalFX metrics.

  • Fixed an issue where Harness was unable to retrieve the Git status or push updates to Azure repos with project names with white spaces. (CI-8105, ZD-44679)

    This issue is fixed.

  • Spot Elastigroup deployments failed to fetch instance health and expired. (CDS-56451, ZD-41436)

    Harness improved the handling mechanism for the Spot instanceHealthiness API to fix this issue.

  • A force delete option appeared when deleting a template referenced by another template. This deleted the referenced template, but the remaining versions were no longer visible on the UI. (CDS-68683)

    Added additional test coverage for some workflows to resolve this issue.

  • Fixed an issue where error logs were removed to stop error flooding into GCP logs when Git authentication fails. (CDS-68760)

  • Fixed an issue where strings were interpreted as scientific notations. (CDS-69063, ZD-44206)

  • Input values needed in steps or stages for execution failed with the error: Cannot update execution status for the PlanExecution [execution Id] with RUNNING. (CDS-69342, ZD-44344)

    This error occurred when converting YAML to JSON. A code enhancement fixed this issue. With this enhancement, quotes inside the field YAML are escaped, resulting in valid YAML.

  • The pipeline execution error message for YAML related errors was unclear. (CDS-69576)

    Improved error message handling for YAML processing failures. The error message now display files that contain errors and points to the problematic part of the file.

  • Bamboo triggers were not working properly. (CDS-69605)

    Adding the Bamboo build to the delegate response resolved this issue.

  • Certificate issues in Harness Delegate version 23.05.79307. (CDS-70410, ZD-45105, ZD-45110, ZD-45128)

    The HTTP step was failing due to absence of the certificate value in the step. In previous delegate versions, the delegate would bypass the absence of this field. However, in delegate version 23.05.79307, this field was incorrectly set as mandatory for HTTP step execution for validations against servers that had self-signed certificates. This issue is fixed.

  • Fixed an issue where the eventPayload expressions were not resolving when rerunning a failed pipeline that was previously fired by using a trigger. (CDS-70559)

May 23, 2023, Harness version 79306, Harness Delegate version 79307​

Harness NextGen release 79306 includes the following changes for the Harness Delegate.

What's new​

  • Added support to provide quartz cron expressions for scheduled triggers. (CDS-59261, CDS-59260)

  • Added support for accessing connector attributes for Deployment Templates. (CDS-54247)

    The connector attributes for Secret Manager connectors can be accessed in Deployment Templates using the following expressions.

  • Git polling tasks for triggers are executed on the same delegate selector used in the Git connector. (CDS-58115)

    Previously, triggers used the round robin algorithm to select any available delegate within a project or account. Now, the delegate-based trigger polling selects the same delegate you used in the connectors for triggers.

  • The Azure Key Vault secret manager now supports creating secrets with expiration dates. Select Expires On to set a secret expiration date. (PL-32708, ZD-42524)

Early access​

  • New delegate metrics are available. This functionality is behind a feature flag, DELEGATE_ENABLE_DYNAMIC_HANDLING_OF_REQUEST. (PL-37908, PL-38538)

    Harness captures delegate agent metrics for delegates shipped on immutable image types. The following new delegate agent metrics are available with the feature flag:

    Metric nameDescription
    task_completedThe number of tasks completed.
    task_failedThe number of failed tasks.
    task_rejectedThe number of tasks rejected because of a high load on the delegate.
    delegate_connectedIndicates whether the delegate is connected. Values are 0 (disconnected) and 1 (connected).
    resource_consumption_above_thresholdDelegate cpu/memory is above a threshold (defaults to 80%). Provide DELEGATE_RESOURCE_THRESHOLD as the env variable in the delegate YAML to configure the threshold.

    Enable the feature flag, DELEGATE_ENABLE_DYNAMIC_HANDLING_OF_REQUEST to use the new delegate agent metrics. When this feature flag is enabled, Harness will capture the metrics. For more information, go to Configure delegate metrics.

Fixed issues​

  • Fixed an issue where the expressions of tags were not rendered properly. (CDS-68703, ZD-43797)

  • Executions were failing with Canary failed: [Canary Deployment failed - NoSuchMethodError: org.yaml.snakeyaml.constructor.SafeConstructor: method 'void <init>()' not found ] error message. (CDS-68293, ZD-43753, ZD-43769)

    The Fabric8 library used by Harness is upgraded from version 5.x to 6.x. Harness was explicitly using snake.yaml version 2.x due to vulnerabilities present in the 1.x version.

    Harness' usages of Fabric8 library were throwing the above mentioned because Fabric8 library version 5.12.1 uses the old snake.yaml library version 1.x.

    Customers who were using the following were affected:

    • FirstGen Kubernetes deployments that contain Istio's VirtualService/DestinationRule objects.
    • FirstGen Traffic Split step.
    • FirstGen Native Helm deployments with Kubernetes cluster version 1.16 or earlier.
    • NextGen Kubernetes deployments that contain Istio's VirtualService/DestinationRule objects.
    • NextGen Native Helm deployments with Kubernetes cluster version 1.16 or earlier.

    This change does not create any behavioral changes.

  • The access denied exception was saving the OAuth secret in the Harness Source Code Manager (SCM) user profile. (CDS-68144)

    This issue is fixed by passing the context correctly from the SCM service to the Git service.

  • Pipelines with multi-level templates displayed Java errors because a secret was referenced by another secret. (CDS-68094)

    This issue is fixed in by improving the error messages.

  • Fixed an issue by eliminating NPE during ASG pipeline execution. (CDS-59383)

  • The Canary Delete step during rollback did not delete all canary resources when the forward Canary Delete step expired. The Canary Delete step uses Harness release history when the Canary Deployment step expires. An API call issue prevented Harness release history from being updated in time and available for the Canary Delete step during rollback. (CDS-58702)

    This issue has been resolved. The Canary Delete step now properly deletes canary workloads when the forward Canary Deployment step expires.

  • Fixed an issue by adding support for retrying sockettimeoutExceptions as they can occur due to intermittent issues during a Kubernetes deployment. (CDS-57688)

  • Invites to users fail with an unauthorized error while RBAC setup is still in progress. (PL-32117)

    A polling system ensures that RBAC setup has been completed.

  • Custom Secret Manager creation does not consider the delegate selector. (PL-32260)

    In Custom SM configuration, decrypting secrets using the SSH connection to validate delegate selection fixed this issue.

  • Deployments consistently failed during the same stage. (PL-38247, ZD-42721)

    This issue was fixed by updating the delegate YAML. Delegate startup now fails when you use a legacy delegate image with an immutable delegate.

April 22, 2023, Harness version 79111, Harness Delegate version 79106​

Harness NextGen release 79111 includes the following changes for the Harness Delegate.

March 15, 2023, Harness version 78712, Harness Delegate version 78705​

Harness NextGen release 78712 includes the following changes for the Harness Delegate.

What's new​

  • Integrated Logs API in the Executed Details page where the delegate task ID is available. (DEL-6035)

    You can now view logs for delegate tasks for pipeline steps that are running or finished. This can help with debugging issues.

  • Set an expiry for delegate tokens. (DEL-5652)

    When you create a delegate token through APIs, you can provide an optional parameter revokeAfter. This is the epoch time in milliseconds after which the token is marked as revoked. There can be a delay of up to one hour from when the epoch value is provided to when the token is revoked.

Early access​

This release does not include any early access features.

Fixed issues​

A pipeline stalled with only one ServiceNow task running. (DEL-6042)

This issue was fixed with the following updates:

  • Tasks that were never assigned to a delegate explicitly fail after 4 successful broadcast attempts per delegate, to all eligible delegates in the account.
  • Fail one minute after the last rebroadcast attempt.

March 8, 2023, Harness version 78619, Harness Delegate version 78500​

Harness NextGen release 78619 includes the following changes for the Harness Delegate.

What's new​

  • The delegate installation UI experience is now updated with a new installation method: the Terraform Helm provider. Also, the installation experience has been enhanced for the existing methods (Helm chart, Kubernetes manifest, and Docker). This new experience is more developer friendly. For example, it enables cutting and pasting of relevant commands. You can also automate the commands and use new values when necessary.

    Additionally, the following new features are available:

    • The Terraform Helm Provider method is based on the open source Terraform Harness Delegate module and the open source Harness Delegate Helm chart. Auto upgrade is set to OFF with an option to enable it in the command.
    • The updated method for Helm Chart is also based on the same open source Harness Delegate Helm chart as the Terraform Helm provider. Auto upgrade is set to OFF with an option to enable it in the command. You can also download the default values.yaml for the Helm option and edit that to set your own long-lived configuration values.
    • The updated flow for Kubernetes Manifest has the following options for creating a manifest YAML file specific to your Harness account.
      • Basic: Provides a Download YAML option. The downloaded YAML has all the configuration variables set to values that are specific to your Harness account.
      • Custom - Create your own YAML from a Kubernetes manifest template by replacing the placeholders with the values provided in the method. Given the need to have a fully qualified YAML, the auto upgrade configuration is set to ON in both the above options. Consequently, the delegate version that is installed always remains in sync with the version available on Harness Manager.
    • The Docker delegate installation method has now been simplified to a copy-and-paste action on the docker run command, with the option to modify the preset values. The auto upgrade is set to OFF for this method, with an option to enable it in the command. (DEL-6037)

  • The secrets manager cache was moved from Redis to the Harness Manager's local pod. (DEL-5884)

    This move further enhances security because the secrets manager configuration no longer goes outside of the Harness Manager's pod.
