Setup Guide

There're 3 ways to set up DevLake: user setup, developer setup and cloud setup.

User setup

• If you only plan to run the product locally, this is the ONLY section you should need.
• 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

1. Clone repository:

   git clone https://github.com/merico-dev/lake.git devlake
   cd devlake
   cp .env.example .env
   

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

3. 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.

4. Visit localhost:4000/triggers to trigger data collection.

   • Please refer to this wiki How to trigger data collection. Data collection can take a while depending on the amount of data you'd like to collect.
   • To collect this repo for a quick preview, you can use the following JSON

     [
       [
         {
           "Plugin": "github",
           "Options": {
             "repositoryName": "lake",
             "owner": "merico-dev"
           }
         }
       ]
     ]
     

5. Click View Dashboards button when done (username: admin, password: admin). The button will be shown on the Trigger Collection page when data collection has finished.

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.

   cd lake
   

2. Install Go packages:

   make install
   

3. Copy the sample config file to new local file:

   cp .env.example .env
   

4. Update the following variables in the file .env:

   • COMPOSE_PROFILES: Change user to dev

5. Start the MySQL and Grafana containers:

   Make sure the Docker daemon is running before this step.

   docker compose up
   

6. Run lake and config UI in dev mode in two seperate terminals:

   # run lake
   make dev
   # run config UI
   make configure-dev
   

7. Visit config UI at localhost:4000 to configure data sources.

   • Navigate to desired plugins pages on the Integrations page

Cloud setup

If you want to run DevLake in a clound environment, you can set up DevLake with Tin. See detailed setup guide

Disclaimer:

To protect your information, it is critical for users of the Tin hosting to set passwords to protect DevLake applications. We built DevLake as a self-hosted product, in part to ensure users have total protection and ownership of their data, while the same remains true for the Tin hosting, this risk point can only be eliminated by the end-user.

Tests

To run the tests:

make test

Grafana

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.
