In the ever-evolving world of cloud infrastructure management, staying ahead of the curve is crucial to ensuring efficiency and reliability. HashiCorp, a leader in infrastructure automation, has introduced a new feature aimed at optimizing the Terraform workflow, a popular tool used for managing infrastructure as code. This feature, now generally available, promises to enhance the speed and efficiency of application delivery by automatically canceling outdated plan-only runs triggered by pull requests in version control systems (VCS) for both HCP Terraform and Terraform Enterprise.
When teams use a VCS such as GitHub, GitLab, or Bitbucket, creating a pull request (PR) can automatically kick off a Terraform run to execute a plan operation. This operation is essentially a dry run that shows what changes Terraform will make without actually applying them. However, in a busy team environment, new commits are often added to the same branch, leading to multiple queued Terraform runs. This accumulation can cause delays and inefficiencies, as each run competes for resources and time. The newly released feature addresses this issue by allowing organizations to automatically cancel plan-only runs for outdated commits, thus preventing unnecessary backlog and streamlining the workflow.
Managing Organization Speculative Plan Settings
To take advantage of this new capability, users need to manage their organization’s speculative plan settings within the Terraform platform. By navigating to the Settings section, then to General under Version Control, users can enable the automatic cancellation option. Once activated, HCP Terraform will monitor the repository for new commits on the same branch and cancel any ongoing or pending speculative plans associated with previous commits. This proactive cancellation ensures that only the most recent and relevant plans are executed, thus improving the efficiency of the development pipeline.
Understanding the Run Details Page
Once a newer commit is pushed to the branch, users will receive a notification indicating that the previous run was automatically canceled. This message provides clarity and transparency, ensuring that team members are aware of the actions taken by Terraform. This feature not only saves time but also reduces the cognitive load on developers, allowing them to focus on more critical tasks.
Updated VCS Status Checks
The introduction of this feature also brings updates to the version control system status checks. For non-aggregated status checks, Terraform will now distinguish between runs that were auto-canceled and those that were manually canceled. This distinction is crucial for maintaining an accurate audit trail and understanding the workflow dynamics. In the case of aggregated status checks, Terraform will include a count of automatically canceled runs as part of the aggregated result, providing a comprehensive view of the run history. This level of detail is invaluable for teams looking to optimize their processes and identify areas for improvement.
Aggregated Status Page Enhancements
In scenarios where multiple runs are automatically canceled for a single commit, Terraform will display an alert in the "Resources to be changed" section. This alert serves as a reminder that the section may not fully reflect the intended changes if all runs were allowed to complete. Users have the option to toggle the visibility of automatically canceled plans, offering flexibility in how information is presented and consumed. This functionality empowers teams to maintain a clear understanding of their infrastructure changes and ensures that decisions are based on the most current data.
Getting Started with the New Feature
These enhancements reflect HashiCorp’s commitment to helping customers maximize their infrastructure investments and accelerate application delivery. By optimizing plan-only Terraform runs through the VCS workflow, users can achieve greater efficiency and agility in their development processes. For those interested in exploring this feature further, detailed documentation is available on HashiCorp’s website. New users can sign up for HCP Terraform and get started free of charge, gaining access to a powerful suite of tools designed to simplify and streamline infrastructure management.
In conclusion, HashiCorp’s new feature for automatically canceling outdated plan-only Terraform runs represents a significant step forward in optimizing infrastructure workflows. By reducing unnecessary runs and ensuring that only the most relevant plans are executed, teams can enhance their productivity and focus on delivering high-quality applications. This development is a testament to HashiCorp’s dedication to innovation and its mission to empower organizations with the tools they need to succeed in a rapidly changing technological landscape.
