Harness Migrator

harness-migrate is a command line utility to help convert and migrate continuous integration pipelines from other providers to Harness CI. You can use this tool to migrate repositories following guidlines below.

Please review known conversion and migration issues before using this tool.

Migrate Repositories

Migrating repositoires is a two-step process.

1. Export: Use git-export to export your repositories from your current provider. Guidlines for Bitbucket On-perm, GitHub, Gitlab, and Bitbucket. The exported data will be saved in a zip file.

2. Import: Import the exported zip file into Harness using git-import to create new repositories as explained here.

Usage

Drone

Convert a drone pipeline:

harness-migrate drone convert /path/to/.drone.yml

Export a github namespace from drone:

harness-migrate drone export \
  --namespace example \
  --github-token $GITHUB_TOKEN \
  export.json

❗ To avoid pipelines triggering in both your Drone instance and in Harness CI, you must first deactivate the pipelines in your Drone instance.

This script uses jq and the Drone CLI to disable all pipelines defined in your export.json:

#!/bin/bash

DRONE_NAMESPACE=$(jq -r .name export.json)
for REPO_NAME in $(jq -r .project[].name export.json); do
  drone repo disable $DRONE_NAMESPACE/$REPO_NAME
done

Import a drone namespace:

harness-migrate drone import \
  --harness-account $HARNESS_ACCOUNT \
  --harness-org example \
  --docker-connector account.harnessImage \
  --github-token $GITHUB_TOKEN \
  export.json

BitBucket

Convert a bitbucket pipeline:

harness-migrate bitbucket convert /path/to/bitbucket-pipelines.yml

CircleCI

Convert a circle pipeline:

harness-migrate circle convert /path/to/.circle/config.yml

GitHub Actions

Convert a github pipeline:

harness-migrate github convert /path/to/.github/workflows/main.yml

GitLab

Convert a gitlab pipeline:

harness-migrate gitlab convert /path/to/.gitlab-ci.yml

Terraform

Generate terraform configuration from an export, and apply it to your Harness account:

$ harness-migrate terraform \
  --account $HARNESS_ACCOUNT \
  --docker-connector account.harnessImage \
  --org $HARNESS_ORG \
  --repo-connector $HARNESS_REPO_CONNECTOR \
  export.json \
  output.tf
$ terraform init
$ terraform apply
