Get started administering GitLab (FREE)

Get started with GitLab administration. Configure your organization and its authentication, then secure, monitor, and back up GitLab.

Authentication

Authentication is the first step in making your installation secure.

  • Enforce two-factor authentication (2FA) for all users. We highly recommended 2FA for self-managed instances.
  • Ensure users do the following:
    • Choose a strong, secure password. If possible, store it in a password management system.
    • If it is not configured for everyone, enable two-factor authentication (2FA) for your account. This one-time secret code is an additional safeguard that keeps intruders out, even if they have your password.
    • Add a backup email. If you lose access to your account, the GitLab Support team can help you more quickly.
    • Save or print your recovery codes. If you can't access your authentication device, you can use these recovery codes to sign in to your GitLab account.
    • Add an SSH key to your profile. You can generate new recovery codes as needed with SSH.
    • Enable personal access tokens. When using 2FA, you can use these tokens to access the GitLab API.

Projects and groups

Organize your environment by configuring your groups and projects.

  • Projects: Designate a home for your files and code or track and organize issues in a business category.
  • Groups: Organize a collection of users or projects. Use these groups to quickly assign people and projects.
  • Roles: Define user access and visibility for your projects and groups.

Import projects

You may need to import projects from external sources like GitHub, Bitbucket, or another instance of GitLab. Many external sources can be imported into GitLab.

  • GitHub Enterprise to self-managed GitLab: Enabling OAuth makes it easier for developers to find and import their projects.
  • Bitbucket Server: There are certain data limitations. For assistance with these data types, contact your GitLab account manager or GitLab Support about our professional migration services.

GitLab instance security

Security is an important part of the onboarding process. Securing your instance protects your work and your organization.

While this isn't an exhaustive list, following these steps gives you a solid start for securing your instance.

Monitor GitLab performance

After you've established your basic setup, you're ready to review the GitLab monitoring services. Prometheus is our core performance monitoring tool. Unlike other monitoring solutions (for example, Zabbix or New Relic), Prometheus is tightly integrated with GitLab and has extensive community support.

Components of monitoring

  • Web servers: Handles server requests and facilitates other back-end service transactions. Monitor CPU, memory, and network IO traffic to track the health of this node.
  • Workhorse: Alleviates web traffic congestion from the main server. Monitor latency spikes to track the health of this node.
  • Sidekiq: Handles background operations that allow GitLab to run smoothly. Monitor for long, unprocessed task queues to track the health of this node.

Back up your GitLab data

GitLab provides backup methods to keep your data safe and recoverable. Whether you use a self-managed or a GitLab SaaS database, it's crucial to back up your data regularly.

  • Decide on a backup strategy.
  • Consider writing a cron job to make daily backups.
  • Separately backup the configuration files.
  • Decide what should be left out of the backup.
  • Decide where to upload the backups.
  • Limit backup lifetime.
  • Run a test backup and restore.
  • Set up a way to periodically verify the backups.

Back up a GitLab self-managed instance

The routine differs, depending on whether you deployed with Omnibus or the Helm chart.

When you backing up an Omnibus (single node) GitLab server, you can use a single Rake task.

Learn about backing up Omnibus or Helm variations. This process backs up your entire instance, but does not back up the configuration files. Ensure those are backed up separately. Keep your configuration files and backup archives in a separate location to ensure the encryption keys are not kept with the encrypted data.

Restore a backup

You can restore a backup only to the exact same version and type (Community Edition/Enterprise Edition) of GitLab on which it was created.

Back up GitLab SaaS

Backups of GitLab databases and filesystems are taken every 24 hours, and are kept for two weeks on a rolling schedule. All backups are encrypted.

  • GitLab SaaS creates backups to ensure your data is secure, but you can't use these methods to export or back up your data yourself.
  • Issues are stored in the database. They can't be stored in Git itself.
  • You can use the project export option in:
  • Group export does not export the projects in it, but does export:
    • Epics
    • Milestones
    • Boards
    • Labels
    • Additional items

For more information about GitLab SaaS backups, see our Backup FAQ page.

Alternative backup strategies

In some situations the Rake task for backups may not be the most optimal solution. Here are some alternatives to consider if the Rake task does not work for you.

Option 1: File system snapshot

If your GitLab server contains a lot of Git repository data, you may find the GitLab backup script to be too slow. It can be especially slow when backing up to an offsite location.

Slowness typically starts at a Git repository data size of around 200 GB. In this case, you might consider using file system snapshots as part of your backup strategy. For example, consider a GitLab server with the following components:

  • Using Omnibus GitLab
  • Hosted on AWS with an EBS drive containing an ext4 file system mounted at /var/opt/gitlab.

The EC2 instance meets the requirements for an application data backup by taking an EBS snapshot. The backup includes all repositories, uploads, and PostgreSQL data.

In general, if you're running GitLab on a virtualized server, you can create VM snapshots of the entire GitLab server. It is common for a VM snapshot to require you to power down the server.

Option 2: GitLab Geo (PREMIUM SELF)

Geo provides local, read-only instances of your GitLab instances.

While GitLab Geo helps remote teams work more efficiently by using a local GitLab node, it can also be used as a disaster recovery solution. Learn more about using Geo as a disaster recovery solution.

Geo replicates your database, your Git repositories, and a few other assets. Learn more about replication limitations.

API and rate limits for self-managed GitLab

Rate limits prevent denial-of-service or brute-force attacks. In most cases, you can reduce the load on your application and infrastructure by limiting the rate of requests from a single IP address.

Rate limits also improve the security of your application.

Configure rate limits for self-managed GitLab

You can make changes to your default rate limits from the Admin Area. For more information about configuration, see the Admin Area page.

For more information about API and rate limits, see our API page.

API and rate limits for GitLab SaaS

Rate limits prevent denial-of-service or brute-force attacks. IP blocks usually happen when GitLab.com receives unusual traffic from a single IP address. The system views unusual traffic as potentially malicious based on rate limit settings.

Rate limits also improve the security of your application.

Configure rate limits for GitLab SaaS

You can make changes to your default rate limits from the Admin Area. For more information about configuration, see the Admin Area page.

  • Review the rate limit page.
  • Read our API page for more information about API and rate limiting.

GitLab SaaS-specific block and error responses

  • 403 forbidden error: If the error occurs for all GitLab SaaS requests, look for an automated process that could have triggered a block. For more assistance, contact GitLab support with your error details, including the affected IP address.
  • HAProxy API throttle: GitLab SaaS responds with HTTP status code 429 to API requests that exceed 10 requests per second, per IP address.
  • Protected paths throttle: GitLab SaaS responds with HTTP status code 429 to POST requests at protected paths that exceed 10 requests per minute, per IP address.
  • Git and container registry failed authentication ban: GitLab SaaS responds with HTTP status code 403 for one hour if it receives 30 failed authentication requests in three minutes from a single IP address.
