FAQ

Can we enable BuildKit support for the native build and push step?​

Currently, our OOTB build and push step utilize Kaniko for building Docker images. To incorporate BuildKit support we would need to use dind build in a run step and more details about dind build can be reffered here

Account verification error for CI Builds (Free Trial account with hosted builds)​

Recently Harness has been the victim of several Crypto attacks that use our freely hosted build to mine cryptocurrencies. Unfortunately, to protect our infrastructure, we now block the use of the cloud-hosted-builds infrastructure only to business domains and block it for general-use domains like Gmail, Hotmail, and Yahoo and other untrusted emails.

To address these issues, you can do one of the following: Provide your own build infrastructure (like a VM with docker or a Kubernetes cluster). We have no limitations on building using your own infrastructure. Creating the Harness account with your work email and not a Gmail address will solve this problem.

Can we change the Git Connector of a template and keep the version, repo, etc?​

There's direct option to change such things. Go to template listing page, click on 3 dots on any template for further options and you will see "edit git metadata" option over there.

How do I share data between steps in a CI stage?​

We could use shared paths to allow steps within a stage to share data with each other. You can specify custom paths for data sharing or cache purposes. For more details on this please refer to https://developer.harness.io/docs/continuous-integration/use-ci/caching-ci-data/share-ci-data-across-steps-and-stages

Is it possible to use different build infrastructures within a pipeline?​

Yes, you can configure different build infrastructures for each stage within a pipeline. This flexibility allows you to use the most suitable infrastructure for each part of your CI workflow.

How can we configure a specific step to only run when a certain file, like a .toml configuration file, has changed in the repository?​

To achieve conditional step execution based on changes to a specific file, you can set up webhook triggers with file-based conditions. Configure the trigger to activate the step only when the targeted file (e.g., config.toml) has been modified in the repository.

How can we share a failed step's output in a pull request comment as part of a CI pipeline execution?​

Below given one of the methods with which we could achieve this.

  • Modify the failed step's command to save output to a file: your_command 2>&1 | tee output_file.log
  • Read the file's content in a subsequent step which is configured to run always
  • Use the GitHub API to add a comment to the pull request, including details from the file.

How can we calculate the instance of a service where number of pods change ?​

We can calculate the service licenses and instances in following methods for CG and NG both.

  • List services deployed in the last 30 days. Service is considered in calculation even if it was part of any failed deployments
  • For every found service we find the 95th Percentile of the number of its service instances across a period of 30 days and it represents active service instances
  • Based on service instances we calculate the number of consumed licenses
  • 1 service license is equal to 20 active service instances

What should we do on experiencing OOM on java heap for the delgate ?​

Try increasing the CPU request and limit both. Check CPU utilisation in-case.

Do we encrypt the image tag for the container during rollout deployment output ?​

No we don't. Try checking SHA of the tag and find image ID from the output of the service step <+artifact.tag>
