# Updating GitLab
|
|
|
|
Depending on the installation method and your GitLab version, there are multiple
|
|
update guides.
|
|
|
|
There are currently 3 official ways to install GitLab:
|
|
|
|
- [Omnibus packages](#omnibus-packages)
|
|
- [Source installation](#installation-from-source)
|
|
- [Docker installation](#installation-using-docker)
|
|
|
|
Based on your installation, choose a section below that fits your needs.
|
|
|
|
## Omnibus Packages
|
|
|
|
- The [Omnibus update guide](https://docs.gitlab.com/omnibus/update/README.html)
|
|
contains the steps needed to update an Omnibus GitLab package.
|
|
|
|
## Installation from source
|
|
|
|
- [Upgrading Community Edition and Enterprise Edition from
|
|
source](upgrading_from_source.md) - The guidelines for upgrading Community
|
|
Edition and Enterprise Edition from source.
|
|
- [Patch versions](patch_versions.md) guide includes the steps needed for a
|
|
patch version, such as 6.2.0 to 6.2.1, and apply to both Community and Enterprise
|
|
Editions.
|
|
|
|
In the past we used separate documents for the upgrading instructions, but we
|
|
have since switched to using a single document. The old upgrading guidelines
|
|
can still be found in the Git repository:
|
|
|
|
- [Old upgrading guidelines for Community Edition](https://gitlab.com/gitlab-org/gitlab-foss/tree/11-8-stable/doc/update)
|
|
- [Old upgrading guidelines for Enterprise Edition](https://gitlab.com/gitlab-org/gitlab/tree/11-8-stable-ee/doc/update)
|
|
|
|
## Installation using Docker
|
|
|
|
GitLab provides official Docker images for both Community and Enterprise
|
|
editions. They are based on the Omnibus package and instructions on how to
|
|
update them are in [a separate document](https://docs.gitlab.com/omnibus/docker/README.html).
|
|
|
|
## Upgrading without downtime
|
|
|
|
Starting with GitLab 9.1.0 it's possible to upgrade to a newer major, minor, or
|
|
patch version of GitLab without having to take your GitLab instance offline.
|
|
However, for this to work there are the following requirements:
|
|
|
|
- You can only upgrade 1 minor release at a time. So from 9.1 to 9.2, not to
|
|
9.3.
|
|
- You have to use [post-deployment
|
|
migrations](../development/post_deployment_migrations.md) (included in
|
|
zero downtime update steps below).
|
|
- You are using PostgreSQL. Starting from GitLab 12.1, MySQL is not supported.
|
|
- Multi-node GitLab instance. Single-node instances may experience brief interruptions
|
|
[as services restart (Puma in particular)](https://docs.gitlab.com/omnibus/update/README.html#single-node-deployment).
|
|
|
|
Most of the time you can safely upgrade from a patch release to the next minor
|
|
release if the patch release is not the latest. For example, upgrading from
|
|
9.1.1 to 9.2.0 should be safe even if 9.1.2 has been released. We do recommend
|
|
you check the release posts of any releases between your current and target
|
|
version just in case they include any migrations that may require you to upgrade
|
|
1 release at a time.
|
|
|
|
Some releases may also include so called "background migrations". These
|
|
migrations are performed in the background by Sidekiq and are often used for
|
|
migrating data. Background migrations are only added in the monthly releases.
|
|
|
|
Certain major/minor releases may require a set of background migrations to be
|
|
finished. To guarantee this such a release will process any remaining jobs
|
|
before continuing the upgrading procedure. While this won't require downtime
|
|
(if the above conditions are met) we recommend users to keep at least 1 week
|
|
between upgrading major/minor releases, allowing the background migrations to
|
|
finish. The time necessary to complete these migrations can be reduced by
|
|
increasing the number of Sidekiq workers that can process jobs in the
|
|
`background_migration` queue. To see the size of this queue,
|
|
[Check for background migrations before upgrading](#checking-for-background-migrations-before-upgrading).
|
|
|
|
As a rule of thumb, any database smaller than 10 GB won't take too much time to
|
|
upgrade; perhaps an hour at most per minor release. Larger databases however may
|
|
require more time, but this is highly dependent on the size of the database and
|
|
the migrations that are being performed.
|
|
|
|
### Examples
|
|
|
|
To help explain this, let's look at some examples.
|
|
|
|
**Example 1:** You are running a large GitLab installation using version 9.4.2,
|
|
which is the latest patch release of 9.4. When GitLab 9.5.0 is released this
|
|
installation can be safely upgraded to 9.5.0 without requiring downtime if the
|
|
requirements mentioned above are met. You can also skip 9.5.0 and upgrade to
|
|
9.5.1 once it's released, but you **can not** upgrade straight to 9.6.0; you
|
|
_have_ to first upgrade to a 9.5.x release.
|
|
|
|
**Example 2:** You are running a large GitLab installation using version 9.4.2,
|
|
which is the latest patch release of 9.4. GitLab 9.5 includes some background
|
|
migrations, and 10.0 will require these to be completed (processing any
|
|
remaining jobs for you). Skipping 9.5 is not possible without downtime, and due
|
|
to the background migrations would require potentially hours of downtime
|
|
depending on how long it takes for the background migrations to complete. To
|
|
work around this you will have to upgrade to 9.5.x first, then wait at least a
|
|
week before upgrading to 10.0.
|
|
|
|
**Example 3:** You use MySQL as the database for GitLab. Any upgrade to a new
|
|
major/minor release will require downtime. If a release includes any background
|
|
migrations this could potentially lead to hours of downtime, depending on the
|
|
size of your database. To work around this you will have to use PostgreSQL and
|
|
meet the other online upgrade requirements mentioned above.
|
|
|
|
### Steps
|
|
|
|
Steps to [upgrade without downtime](https://docs.gitlab.com/omnibus/update/README.html#zero-downtime-updates).
|
|
|
|
## Checking for background migrations before upgrading
|
|
|
|
Certain major/minor releases may require a set of background migrations to be
|
|
finished. The number of remaining migrations jobs can be found by running the
|
|
following command:
|
|
|
|
**For Omnibus installations**
|
|
|
|
If using GitLab 12.9 and newer, run:
|
|
|
|
```shell
|
|
sudo gitlab-rails runner -e production 'puts Gitlab::BackgroundMigration.remaining'
|
|
```
|
|
|
|
If using GitLab 12.8 and older, run the following using a [Rails console](../administration/troubleshooting/debug.md#starting-a-rails-console-session):
|
|
|
|
```ruby
|
|
puts Sidekiq::Queue.new("background_migration").size
|
|
Sidekiq::ScheduledSet.new.select { |r| r.klass == 'BackgroundMigrationWorker' }.size
|
|
```
|
|
|
|
---
|
|
|
|
**For installations from source**
|
|
|
|
If using GitLab 12.9 and newer, run:
|
|
|
|
```shell
|
|
cd /home/git/gitlab
|
|
sudo -u git -H bundle exec rails runner -e production 'puts Gitlab::BackgroundMigration.remaining'
|
|
```
|
|
|
|
If using GitLab 12.8 and older, run the following using a [Rails console](../administration/troubleshooting/debug.md#starting-a-rails-console-session):
|
|
|
|
```ruby
|
|
puts Sidekiq::Queue.new("background_migration").size
|
|
Sidekiq::ScheduledSet.new.select { |r| r.klass == 'BackgroundMigrationWorker' }.size
|
|
```
|
|
|
|
### What do I do if my background migrations are stuck?
|
|
|
|
CAUTION: **Warning:**
|
|
The following operations can disrupt your GitLab performance.
|
|
|
|
NOTE: **Note:**
|
|
It is safe to re-execute these commands, especially if you have 1000+ pending jobs which would likely overflow your runtime memory.
|
|
|
|
**For Omnibus installations**
|
|
|
|
```shell
|
|
# Start the rails console
|
|
sudo gitlab-rails c
|
|
|
|
# Execute the following in the rails console
|
|
scheduled_queue = Sidekiq::ScheduledSet.new
|
|
pending_job_classes = scheduled_queue.select { |job| job["class"] == "BackgroundMigrationWorker" }.map { |job| job["args"].first }.uniq
|
|
pending_job_classes.each { |job_class| Gitlab::BackgroundMigration.steal(job_class) }
|
|
```
|
|
|
|
**For installations from source**
|
|
|
|
```shell
|
|
# Start the rails console
|
|
sudo -u git -H bundle exec rails RAILS_ENV=production
|
|
|
|
# Execute the following in the rails console
|
|
scheduled_queue = Sidekiq::ScheduledSet.new
|
|
pending_job_classes = scheduled_queue.select { |job| job["class"] == "BackgroundMigrationWorker" }.map { |job| job["args"].first }.uniq
|
|
pending_job_classes.each { |job_class| Gitlab::BackgroundMigration.steal(job_class) }
|
|
```
|
|
|
|
## Upgrading to a new major version
|
|
|
|
Major versions are reserved for backwards incompatible changes. We recommend that
|
|
you first upgrade to the latest available minor version within your major version.
|
|
Please follow the [Upgrade Recommendations](../policy/maintenance.md#upgrade-recommendations)
|
|
to identify a supported upgrade path.
|
|
|
|
Before upgrading to a new major version, you should ensure that any background
|
|
migration jobs from previous releases have been completed. To see the current size
|
|
of the `background_migration` queue, [check for background migrations before upgrading](#checking-for-background-migrations-before-upgrading).
|
|
|
|
## Upgrading between editions
|
|
|
|
GitLab comes in two flavors: [Community Edition](https://about.gitlab.com/features/#community) which is MIT licensed,
|
|
and [Enterprise Edition](https://about.gitlab.com/features/#enterprise) which builds on top of the Community Edition and
|
|
includes extra features mainly aimed at organizations with more than 100 users.
|
|
|
|
Below you can find some guides to help you change editions easily.
|
|
|
|
### Community to Enterprise Edition
|
|
|
|
NOTE: **Note:**
|
|
The following guides are for subscribers of the Enterprise Edition only.
|
|
|
|
If you wish to upgrade your GitLab installation from Community to Enterprise
|
|
Edition, follow the guides below based on the installation method:
|
|
|
|
- [Source CE to EE update guides](upgrading_from_ce_to_ee.md) - The steps are very similar
|
|
to a version upgrade: stop the server, get the code, update configuration files for
|
|
the new functionality, install libraries and do migrations, update the init
|
|
script, start the application and check its status.
|
|
- [Omnibus CE to EE](https://docs.gitlab.com/omnibus/update/README.html#updating-community-edition-to-enterprise-edition) - Follow this guide to update your Omnibus
|
|
GitLab Community Edition to the Enterprise Edition.
|
|
|
|
### Enterprise to Community Edition
|
|
|
|
If you need to downgrade your Enterprise Edition installation back to Community
|
|
Edition, you can follow [this guide](../downgrade_ee_to_ce/README.md) to make the process as smooth as
|
|
possible.
|
|
|
|
## Version specific upgrading instructions
|
|
|
|
### 13.3.0
|
|
|
|
The recommended Git version is Git v2.28. The minimum required version of Git
|
|
v2.24 remains the same.
|
|
|
|
### 13.2.0
|
|
|
|
GitLab installations that have multiple web nodes will need to be
|
|
[upgraded to 13.1](#1310) before upgrading to 13.2 (and later) due to a
|
|
breaking change in Rails that can result in authorization issues.
|
|
|
|
GitLab 13.2.0 [remediates](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/35492) an [email verification bypass](https://about.gitlab.com/releases/2020/05/27/security-release-13-0-1-released/).
|
|
After upgrading, if some of your users are unexpectedly encountering 404 or 422 errors when signing in,
|
|
or "blocked" messages when using the command line,
|
|
their accounts may have been un-confirmed.
|
|
In that case, please ask them to check their email for a re-confirmation link.
|
|
For more information, see our discussion of [Email confirmation issues](../user/upgrade_email_bypass.md).
|
|
|
|
GitLab 13.2.0 relies on the `btree_gist` extension for PostgreSQL. For installations with an externally managed PostgreSQL setup, please make sure to
|
|
[install the extension manually](https://www.postgresql.org/docs/11/sql-createextension.html) before upgrading GitLab if the database user for GitLab
|
|
is not a superuser. This is not necessary for installations using a GitLab managed PostgreSQL database.
|
|
|
|
### 13.1.0
|
|
|
|
In 13.1.0, you must upgrade to either:
|
|
|
|
- At least Git v2.24 (previously, the minimum required version was Git v2.22).
|
|
- The recommended Git v2.26.
|
|
|
|
Failure to do so will result in internal errors in the Gitaly service in some RPCs due
|
|
to the use of the new `--end-of-options` Git flag.
|
|
|
|
Additionally, in GitLab 13.1.0, the version of [Rails was upgraded from 6.0.3 to
|
|
6.0.3.1](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/33454).
|
|
The Rails upgrade included a change to CSRF token generation which is
|
|
not backwards-compatible - GitLab servers with the new Rails version
|
|
will generate CSRF tokens that are not recognizable by GitLab servers
|
|
with the older Rails version - which could cause non-GET requests to
|
|
fail for [multi-node GitLab installations](https://docs.gitlab.com/omnibus/update/#multi-node--ha-deployment).
|
|
|
|
So, if you are using multiple Rails servers and specifically upgrading from 13.0,
|
|
all servers must first be upgraded to 13.1.0 before upgrading to later versions:
|
|
|
|
1. Ensure all GitLab web nodes are on GitLab 13.1.0.
|
|
1. Optionally, enable the `global_csrf_token` feature flag to enable new
|
|
method of CSRF token generation:
|
|
|
|
```ruby
|
|
Feature.enable(:global_csrf_token)
|
|
```
|
|
|
|
1. Only then, continue to upgrade to later versions of GitLab.
|
|
|
|
### 12.2.0
|
|
|
|
In 12.2.0, we enabled Rails' authenticated cookie encryption. Old sessions are
|
|
automatically upgraded.
|
|
|
|
However, session cookie downgrades are not supported. So after upgrading to 12.2.0,
|
|
any downgrades would result to all sessions being invalidated and users are logged out.
|
|
|
|
### 12.0.0
|
|
|
|
In 12.0.0 we made various database related changes. These changes require that
|
|
users first upgrade to the latest 11.11 patch release. Once upgraded to 11.11.x,
|
|
users can upgrade to 12.0.x. Failure to do so may result in database migrations
|
|
not being applied, which could lead to application errors.
|
|
|
|
It is also required that you upgrade to 12.0.x before moving to a later version
|
|
of 12.x.
|
|
|
|
Example 1: you are currently using GitLab 11.11.8, which is the latest patch
|
|
release for 11.11.x. You can upgrade as usual to 12.0.x.
|
|
|
|
Example 2: you are currently using a version of GitLab 10.x. To upgrade, first
|
|
upgrade to the last 10.x release (10.8.7) then the last 11.x release (11.11.8).
|
|
Once upgraded to 11.11.8 you can safely upgrade to 12.0.x.
|
|
|
|
See our [documentation on upgrade paths](../policy/maintenance.md#upgrade-recommendations)
|
|
for more information.
