User setup

• If you only plan to run the product locally, this is the ONLY section you should need.
• If you want to run in a cloud environment, click here.
• Commands written like this are to be run in your terminal.

Required Packages to Install

• Docker
• docker-compose

NOTE: After installing docker, you may need to run the docker application and restart your terminal

Commands to run in your terminal

IMPORTANT: DevLake doesn't support Database Schema Migration yet, upgrading an existing instance is likely to break, we recommend that you deploy a new instance instead.

1. Download docker-compose.yml and env.example from latest release page into a folder

2. Rename env.example to .env

3. Start Docker on your machine, then run docker-compose up -d to start the services.

4. Visit localhost:4000 to setup configuration files.

   • Navigate to desired plugins pages on the Integrations page
   • You will need to enter the required information for the plugins you intend to use.
   • Please reference the following for more details on how to configure each one: -> Jira -> GitLab -> Jenkins -> GitHub

   • Submit the form to update the values by clicking on the Save Connection button on each form page

   • devlake takes a while to fully boot up. if config-ui complaining about api being unreachable, please wait a few seconds and try refreshing the page.
   • To collect this repo for a quick preview, please provide a Github personal token on Data Integrations / Github page.

5. Visit localhost:4000/create-pipeline to RUN a Pipeline and trigger data collection.

   Pipelines Runs can be initiated by the new "Create Run" Interface. Simply enable the Data Source Providers you wish to run collection for, and specify the data you want to collect, for instance, Project ID for Gitlab and Repository Name for GitHub.

   Once a valid pipeline configuration has been created, press Create Run to start/run the pipeline. After the pipeline starts, you will be automatically redirected to the Pipeline Activity screen to monitor collection activity.

   Pipelines is accessible from the main menu of the config-ui for easy access.

   • Manage All Pipelines http://localhost:4000/pipelines
   • Create Pipeline RUN http://localhost:4000/create-pipeline
   • Track Pipeline Activity http://localhost:4000/pipelines/activity/[RUN_ID]

   For advanced use cases and complex pipelines, please use the Raw JSON API to manually initiate a run using cURL or graphical API tool such as Postman. POST the following request to the DevLake API Endpoint.

   [
       [
           {
               "plugin": "github",
               "options": {
                   "repo": "lake",
                   "owner": "merico-dev"
               }
           }
       ]
   ]

   Please refer to this wiki How to trigger data collection.

6. Click View Dashboards button in the top left when done, or visit localhost:3002 (username: admin, password: admin).

   We use Grafana as a visualization tool to build charts for the data stored in our database. Using SQL queries, we can add panels to build, save, and edit customized dashboards.

   All the details on provisioning and customizing a dashboard can be found in the Grafana Doc.

Setup cron job

To synchronize data periodically, we provide lake-cli for easily sending data collection requests along with a cron job to periodically trigger the cli tool.
