# Place GitLab into a read-only state **(FREE SELF)**
|
|
|
|
WARNING:
|
|
This document should be used as a temporary solution.
|
|
There's work in progress to make this
|
|
[possible with Geo](https://gitlab.com/groups/gitlab-org/-/epics/2149).
|
|
|
|
In some cases, you might want to place GitLab under a read-only state.
|
|
The configuration for doing so depends on your desired outcome.
|
|
|
|
## Make the repositories read-only
|
|
|
|
The first thing you'll want to accomplish is to ensure that no changes can be
|
|
made to your repositories. There's two ways you can accomplish that:
|
|
|
|
- Either stop Unicorn/Puma to make the internal API unreachable:
|
|
|
|
```shell
|
|
sudo gitlab-ctl stop puma # or unicorn
|
|
```
|
|
|
|
- Or, open up a Rails console:
|
|
|
|
```shell
|
|
sudo gitlab-rails console
|
|
```
|
|
|
|
And set the repositories for all projects read-only:
|
|
|
|
```ruby
|
|
Project.all.find_each { |project| project.update!(repository_read_only: true) }
|
|
```
|
|
|
|
When you're ready to revert this, you can do so with the following command:
|
|
|
|
```ruby
|
|
Project.all.find_each { |project| project.update!(repository_read_only: false) }
|
|
```
|
|
|
|
## Shut down the GitLab UI
|
|
|
|
If you don't mind shutting down the GitLab UI, then the easiest approach is to
|
|
stop `sidekiq` and `puma`/`unicorn`, and you'll effectively ensure that no
|
|
changes can be made to GitLab:
|
|
|
|
```shell
|
|
sudo gitlab-ctl stop sidekiq
|
|
sudo gitlab-ctl stop puma # or unicorn
|
|
```
|
|
|
|
When you're ready to revert this:
|
|
|
|
```shell
|
|
sudo gitlab-ctl start sidekiq
|
|
sudo gitlab-ctl start puma # or unicorn
|
|
```
|
|
|
|
## Make the database read-only
|
|
|
|
If you want to allow users to use the GitLab UI, then you'll need to ensure that
|
|
the database is read-only:
|
|
|
|
1. Take a [GitLab backup](../raketasks/backup_restore.md#back-up-gitlab)
|
|
in case things don't go as expected.
|
|
1. Enter PostgreSQL on the console as an administrator user:
|
|
|
|
```shell
|
|
sudo \
|
|
-u gitlab-psql /opt/gitlab/embedded/bin/psql \
|
|
-h /var/opt/gitlab/postgresql gitlabhq_production
|
|
```
|
|
|
|
1. Create the `gitlab_read_only` user. Note that the password is set to `mypassword`,
|
|
change that to your liking:
|
|
|
|
```sql
|
|
-- NOTE: Use the password defined earlier
|
|
CREATE USER gitlab_read_only WITH password 'mypassword';
|
|
GRANT CONNECT ON DATABASE gitlabhq_production to gitlab_read_only;
|
|
GRANT USAGE ON SCHEMA public TO gitlab_read_only;
|
|
GRANT SELECT ON ALL TABLES IN SCHEMA public TO gitlab_read_only;
|
|
GRANT SELECT ON ALL SEQUENCES IN SCHEMA public TO gitlab_read_only;
|
|
|
|
-- Tables created by "gitlab" should be made read-only for "gitlab_read_only"
|
|
-- automatically.
|
|
ALTER DEFAULT PRIVILEGES FOR USER gitlab IN SCHEMA public GRANT SELECT ON TABLES TO gitlab_read_only;
|
|
ALTER DEFAULT PRIVILEGES FOR USER gitlab IN SCHEMA public GRANT SELECT ON SEQUENCES TO gitlab_read_only;
|
|
```
|
|
|
|
1. Get the hashed password of the `gitlab_read_only` user and copy the result:
|
|
|
|
```shell
|
|
sudo gitlab-ctl pg-password-md5 gitlab_read_only
|
|
```
|
|
|
|
1. Edit `/etc/gitlab/gitlab.rb` and add the password from the previous step:
|
|
|
|
```ruby
|
|
postgresql['sql_user_password'] = 'a2e20f823772650f039284619ab6f239'
|
|
postgresql['sql_user'] = "gitlab_read_only"
|
|
```
|
|
|
|
1. Reconfigure GitLab and restart PostgreSQL:
|
|
|
|
```shell
|
|
sudo gitlab-ctl reconfigure
|
|
sudo gitlab-ctl restart postgresql
|
|
```
|
|
|
|
When you're ready to revert the read-only state, you'll need to remove the added
|
|
lines in `/etc/gitlab/gitlab.rb`, and reconfigure GitLab and restart PostgreSQL:
|
|
|
|
```shell
|
|
sudo gitlab-ctl reconfigure
|
|
sudo gitlab-ctl restart postgresql
|
|
```
|
|
|
|
Once you verify all works as expected, you can remove the `gitlab_read_only`
|
|
user from the database.
