Unable to run Azure pipeline “A task is missing The pipeline references a task called ‘Cache’


The task will utilize AzureCLI to create the resource group, storage account, and container as specified in the backend configuration. This is specified via the providerGoogleCredentials input. This input should be the https://www.globalcloudteam.com/azure-devops-services-what-is-it-and-when-does-your-business-need/ name of the secure file containing the JSON formatted key. When an azure service connection is provided and runAzLogin is set to true, the terraform cli task will run az login using the service connection credentials.

  • Sensitive variables will be set as secret pipeline variables and their values will not be emitted to the pipeline logs.
  • This might be useful if you have some issues when triggering builds at nearly the same time.
  • In order to use the TriggeredBuildIds variable in different jobs/stages, you must make use of the Azure Pipelines multi-job/multi-stage mechanism.
  • Now you fix the dependent build and you automatically want to trigger the build that failed during the nightly-run, but you only want to do that if it failed before.
  • There is a dedicated Task that can be used in order to wait for triggered Builds to finish.
  • When run, if the version is out of date, the task will log a warning to the pipeline summary if there is a newer version of terraform available.

See above for whom the build will be triggered depending on the specified authentication method. This build task enables the chaining of builds within TFS. This will cause TERRAFORM_LAST_EXITCODE to be 2 when plan includes changes; which is a successful exitcode. Additionally, warnings will be logged to the pipeline summary when changes are present as a means to alert that changes will be made if the templates are applied.

Define here if you wish to delay the builds that are triggered by the specified amount of seconds. This might be useful if you have some issues when triggering builds at nearly the same time. There is a dedicated Task that can be used in order to wait for triggered Builds to finish. When using this Task instead of the above mentioned option, you can do other Tasks in between and just start waiting at the latest possible moment.

It is recommended to not use plaintext here, but make use of variables – especially for the password. If you disable this option, you can specify the source-branch that shall be used yourself. If you don’t define anything, the source-branch parameter will not be specified and the default will be used. Other cloud providers can be configured using secure env files. Setting runAzLogin to false will indicate the task should not execute az login with specified service connection. The TerraformCLI task supports configuring the following public cloud providers.

Fail Task if Any Condition is not fulfilled

Alternatively you can also specify the id of the build definition. If you use the name, it must match with what you defined as name for your build definition. If the build you want to trigger is defined in the same team project as the build definition you are currently modifying, you can leave the checkbox checked.

Tasks can also be deployed with an Azure DevOps extension. See this tutorial for how to write a custom task and package it inside an extension. For uploading custom tasks to Azure Pipelines use the TFS Cross Platform Command Line utility. In a first class way and handle return codes, how to treat std/err out, and how to write timeline records based on expected output. They also get access to credentials to write back to TFS/Azure Pipelines.


This version of the tasks are making use now of the official node.js library from Microsoft to access the VSTS/ADO/TFS instead of relying on a custom implementation. While normally it should work compatibility cannot be guaranteed for Azure DevOps Server versions. Especially older versions could get issues due to not supported api calls or outdated dependencies. Setting runAzLogin to true will indicate the task should execute az login with specified service connection. If you have enabled Basic Authentication, you can as well use this sort of authentication by providing the username and password.

There is as well the option to cancel all awaited builds if you are failing the task due to a build that failed. This will then stop other builds and free up the build queue. The option to authenticate via default credentials was removed as it is not well supported within Node.js. The task currently automatically will switch to OAuth if Default is still used – however this option will be removed in an upcoming version.

Known Issues

When queuing a build additional demands can be specified, for example to filter for a special build agent. If additional demands need to be specified, they can be added here. Multiple demands can be specified when they are separated by a comma. The installer task supports installing the latest terraform version by using the keyword latest as the version specified. This is the default option when the installer is added to a pipeline. Specifying latest will instruct the task to lookup and install the latest version of the terraform executable.

The Task uses as an input the Stored Build ID’s (see below) of any Trigger Build Task that was running before and that set the option of storing the IDs. Furthermore you can select whether the subsequent builds that are triggered should be run as it would be requested by the same user that triggered the original build or not. This can be useful if you have any kind of query that https://www.globalcloudteam.com/ is based on the name, for example if you want to filter for builds triggered by you or if you have setup email alerts. If aws selected, the task allows for configuring a service connection as well as the bucket details to use for the backend. This provides open examples on how we write tasks which will help you write other tasks which can be uploaded to your account or server.

We read every piece of feedback, and take your input very seriously. In case you have issues, for example exceptions when you run the Task make sure that the Authentication Option selected is valid. If you still have problems, please open a new issue at issues. This option is not supported anymore – when used the script will automatically try to use the OAuth Token instead to provide support for. However it will create a warning and you should change it yourself to another Authentication Method as this will option will be removed in the future.

You can as well define multiple build that you want to trigger by separating the names with a comma. Additionally there is the option that the condition should take into account builds that are currently being run. A small exception of that rule is if the current build definition is blocking. This one will always just be checked for additional builds in the queue, as there will always be one in progress. When running terraform plan with -detailed-exitcode, a pipeline variable will be set to indicate if any changes exist in the plan.

The authentication is done via a key in json file format provided by Google Cloud IAM. The key file can be uploaded to Secure Files in Azure DevOps and referenced from the task. When executing commands that interact with AWS such as plan, apply, and destroy, the task can utilize AWS Service Connection to authorize operations. The region can also be provided via providerAwsRegion input. The task supports running terraform version individually. When run, if the version is out of date, the task will log a warning to the pipeline summary if there is a newer version of terraform available.
