Learn how to – Install Sourcegraph code search engine on Ubuntu 22.04|20.04|18.04|16.04.
This guide is for installing Sourcegraph on Ubuntu 22.04|20.04|18.04|16.04. Sourcegraph is a fast, open-source, fully-featured code search and navigation engine. Sourcegraph is used in indexing millions of open source repositories across several code hosts. Being open source solution means you can install it now and start using it.
Features of Sourcegraph
Sourcegraph has the following features:
- Fast global code search with a hybrid backend that combines a trigram index with in-memory streaming
- Code intelligence for many languages via the Language Server Protocol
- Enhances GitHub, GitLab, Phabricator, and other code hosts and code review tools via the Sourcegraph browser extension
- Integration with third-party developer tools via the Sourcegraph Extension API

There are two ways to run Sourcegraph on Ubuntu Linux system
- Running Sourcegraph in Docker
- Installing Sourcegraph on your local system
The method we’ll use in this guide is running Sourcegraph in Docker, which is the easiest and recommended.
Step 1: Install Docker Engine
You need Docker Engine installed and running on your system, use our Docker installation guide Install Docker CE on Ubuntu / Debian / Fedora / Arch / CentOS
After installation of Docker CE, add user to docker group:
sudo usermod -aG docker $USER
newgrp dockerYou can check the installed version of Docker using the command:
$ docker version

Step 2: Start Sourcegraph container
Once Docker is running, you can start Sourcegraph container by executing commands below on your terminal.
Use the commands below to run an instance of Sourcegraph locally using Docker. The Sourcegraph image tags can be checked from Docker hub.
docker run -d --name sourcegraph
--publish 7080:7080
--publish 127.0.0.1:3370:3370
--rm
--volume ~/.sourcegraph/config:/etc/sourcegraph
--volume ~/.sourcegraph/data:/var/opt/sourcegraph
sourcegraph/server:3.36.3List running containers:
$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

Manage Sourcegraph with Systemd ( recommended)
It is possible to manage sourcegraph docker container with systemd. First delete the container running:
$ docker rm -f sourcegraph
sourcegraph
$ docker ps

sudo systemctl daemon-reload
sudo systemctl start sourcegraph.serviceConfirm status:
$ systemctl status sourcegraph.service

When Sourcegraph is ready, access the web interface by visiting.http://serverip:7080
On first access, you’ll be prompted to create an admin account.
Step 3: Add Repositories
As an example, we’ll add Github repository to Sourcegraph. For this, you need to create a new Access Token from https://github.com/settings/tokens/new .
Give the token a name and access privileges. The repo scope should be enough for Sourcegraph to access and clone the repositories on your Github account.
Make sure to copy your new personal access token after creation since you won’t be able to see it again!.
Once you have the Github token ID, Login to Sourcegraph Dashboard and navigate to Admin > Configuration > Add Github.com repositories. Add your token ID under the token quotes section and save the changes.
Like:
"token": "9bc5a980e443373b9ffd5e46e7dce3cbe863021b"After a short while, your Github repositories should appear under the Repositories section but disabled.
Enable these repositories to start searching on them.
You can learn more on how to Add Repositories to Sourcegraph. Refer the Official Documentation for other Configurations and tweaks.
