Sidekiq requires connection to the Redis, PostgreSQL, and Gitaly instances. ## Configure TCP access for PostgreSQL, Gitaly, and Redis By default, GitLab uses UNIX sockets and is not set up to communicate via TCP. To change this: 1. Edit the `/etc/gitlab/gitlab.rb` file on your GitLab instance, and add the following: ```ruby ## PostgreSQL # Replace POSTGRESQL_PASSWORD_HASH with a generated md5 value postgresql['sql_user_password'] = 'POSTGRESQL_PASSWORD_HASH' postgresql['listen_address'] = '0.0.0.0' postgresql['port'] = 5432 # Add the Sidekiq nodes to PostgreSQL's trusted addresses. # In the following example, 10.10.1.30/32 is the private IP # of the Sidekiq server. postgresql['md5_auth_cidr_addresses'] = %w(127.0.0.1/32 10.10.1.30/32) postgresql['trust_auth_cidr_addresses'] = %w(127.0.0.1/32 10.10.1.30/32) ## Gitaly # Make Gitaly accept connections on all network interfaces gitaly['listen_addr'] = "0.0.0.0:8075" ## Set up the Gitaly token as a form of authentication since you are accessing Gitaly over the network ## https://docs.gitlab.com/ee/administration/gitaly/configure_gitaly.html#about-the-gitaly-token gitaly['auth_token'] = 'abc123secret' praefect['auth_token'] = 'abc123secret' gitlab_rails['gitaly_token'] = 'abc123secret' ## Redis configuration redis['bind'] = '0.0.0.0' redis['port'] = 6379 # Password to Authenticate Redis redis['password'] = 'redis-password-goes-here' gitlab_rails['redis_password'] = 'redis-password-goes-here' gitlab_rails['auto_migrate'] = false ``` 1. Run `reconfigure`: ```shell sudo gitlab-ctl reconfigure ``` 1. Restart the `PostgreSQL` server: ```shell sudo gitlab-ctl restart postgresql ``` 1. After the restart, set `auto_migrate` to `true` or comment to use the default settings: ```ruby gitlab_rails['auto_migrate'] = true ``` 1. Run `reconfigure` again: ```shell sudo gitlab-ctl reconfigure ``` ## Set up Sidekiq instance 1. SSH into the Sidekiq server. 1. Confirm that you can access the PostgreSQL, Gitaly, and Redis ports: ```shell telnet 5432 # PostgreSQL telnet 8075 # Gitaly telnet 6379 # Redis ``` 1. [Download and install](https://about.gitlab.com/install/) the Omnibus GitLab package using steps 1 and 2. **Do not complete any other steps.** 1. Copy the `/etc/gitlab/gitlab.rb` file from the GitLab instance and add the following settings. Make sure to replace them with your values: ```ruby ######################################## ##### Services Disabled ### ######################################## # # When running GitLab on just one server, you have a single `gitlab.rb` # to enable all services you want to run. # When running GitLab on N servers, you have N `gitlab.rb` files. # Enable only the services you want to run on each # specific server, while disabling all others. # gitaly['enable'] = false postgresql['enable'] = false redis['enable'] = false nginx['enable'] = false puma['enable'] = false gitlab_workhorse['enable'] = false prometheus['enable'] = false alertmanager['enable'] = false grafana['enable'] = false gitlab_exporter['enable'] = false gitlab_kas['enable'] = false ## ## To maintain uniformity of links across nodes, the ## `external_url` on the Sidekiq server should point to the external URL that users ## use to access GitLab. This can be either: ## ## - The `external_url` set on your application server. ## - The URL of a external load balancer, which routes traffic to the GitLab application server. ## external_url 'https://gitlab.example.com' # Configure the gitlab-shell API callback URL. Without this, `git push` will # fail. This can be your 'front door' GitLab URL or an internal load # balancer. gitlab_rails['internal_api_url'] = 'GITLAB_URL' gitlab_shell['secret_token'] = 'SHELL_TOKEN' ######################################## #### Redis ### ######################################## ## Must be the same in every sentinel node. redis['master_name'] = 'gitlab-redis' # Required if you have setup redis cluster ## The same password for Redis authentication you set up for the master node. redis['master_password'] = '' ### If redis is running on the main Gitlab instance and you have opened the TCP port as above add the following gitlab_rails['redis_host'] = '' gitlab_rails['redis_port'] = 6379 ####################################### ### Gitaly ### ####################################### ## Replace with the one you set up, see ## https://docs.gitlab.com/ee/administration/gitaly/configure_gitaly.html#about-the-gitaly-token git_data_dirs({ "default" => { "gitaly_address" => "tcp://:8075", "gitaly_token" => "" } }) ####################################### ### Postgres ### ####################################### # Replace and gitlab_rails['db_host'] = '' gitlab_rails['db_port'] = '5432' gitlab_rails['db_password'] = '' ## Prevent database migrations from running on upgrade automatically gitlab_rails['auto_migrate'] = false ####################################### ### Sidekiq configuration ### ####################################### sidekiq['enable'] = true sidekiq['listen_address'] = "0.0.0.0" ## Set number of Sidekiq queue processes to the same number as available CPUs sidekiq['queue_groups'] = ['*'] * 4 ## Set number of Sidekiq threads per queue process to the recommend number of 10 sidekiq['max_concurrency'] = 10 ``` 1. Copy the `/etc/gitlab/gitlab-secrets.json` file from the GitLab instance and replace the file in the Sidekiq instance. 1. Reconfigure GitLab: ```shell sudo gitlab-ctl reconfigure ``` 1. Restart the Sidekiq instance after completing the process and finishing the database migrations. ## Configure multiple Sidekiq nodes with shared storage If you run multiple Sidekiq nodes with a shared file storage, such as NFS, you must specify the UIDs and GIDs to ensure they match between servers. Specifying the UIDs and GIDs prevents permissions issues in the file system. This advice is similar to the [advice for Geo setups](geo/replication/multiple_servers.md#step-4-configure-the-frontend-application-nodes-on-the-geo-secondary-site). To set up multiple Sidekiq nodes: 1. Edit `/etc/gitlab/gitlab.rb`: ```ruby user['uid'] = 9000 user['gid'] = 9000 web_server['uid'] = 9001 web_server['gid'] = 9001 registry['uid'] = 9002 registry['gid'] = 9002 ``` 1. Reconfigure GitLab: ```shell sudo gitlab-ctl reconfigure ``` ## Configure the Container Registry when using an external Sidekiq If you're using the Container Registry and it's running on a different node than Sidekiq, follow the steps below. 1. Edit `/etc/gitlab/gitlab.rb`, and configure the registry URL: ```ruby registry_external_url 'https://registry.example.com' gitlab_rails['registry_api_url'] = "https://registry.example.com" ``` 1. Reconfigure GitLab: ```shell sudo gitlab-ctl reconfigure ``` 1. In the instance where Container Registry is hosted, copy the `registry.key` file to the Sidekiq node. ## Configure the Sidekiq metrics server If you want to collect Sidekiq metrics, enable the Sidekiq metrics server. To make metrics available from `localhost:8082/metrics`: To configure the metrics server: 1. Edit `/etc/gitlab/gitlab.rb`: ```ruby sidekiq['metrics_enabled'] = true sidekiq['listen_address'] = "localhost" sidekiq['listen_port'] = "8082" # Optionally log all the metrics server logs to log/sidekiq_exporter.log sidekiq['exporter_log_enabled'] = true ``` 1. Reconfigure GitLab: ```shell sudo gitlab-ctl reconfigure ``` ### Enable HTTPS > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/364771) in GitLab 15.2. To serve metrics via HTTPS instead of HTTP, enable TLS in the exporter settings: 1. Edit `/etc/gitlab/gitlab.rb` to add (or find and uncomment) the following lines: ```ruby sidekiq['exporter_tls_enabled'] = true sidekiq['exporter_tls_cert_path'] = "/path/to/certificate.pem" sidekiq['exporter_tls_key_path'] = "/path/to/private-key.pem" ``` 1. Save the file and [reconfigure GitLab](restart_gitlab.md#omnibus-gitlab-reconfigure) for the changes to take effect. When TLS is enabled, the same `port` and `address` are used as described above. The metrics server cannot serve both HTTP and HTTPS at the same time. ## Configure health checks If you use health check probes to observe Sidekiq, enable the Sidekiq health check server. To make health checks available from `localhost:8092`: 1. Edit `/etc/gitlab/gitlab.rb`: ```ruby sidekiq['health_checks_enabled'] = true sidekiq['health_checks_listen_address'] = "localhost" sidekiq['health_checks_listen_port'] = "8092" ``` 1. Reconfigure GitLab: ```shell sudo gitlab-ctl reconfigure ``` For more information about health checks, see the [Sidekiq health check page](sidekiq_health_check.md). ## Configure LDAP and user or group synchronization If you use LDAP for user and group management, you must add the LDAP configuration to your Sidekiq node as well as the LDAP synchronization worker. If the LDAP configuration and LDAP synchronization worker are not applied to your Sidekiq node, users and groups are not automatically synchronized. For more information about configuring LDAP for GitLab, see: - [GitLab LDAP configuration documentation](auth/ldap/index.md#configure-ldap) - [LDAP synchronization documentation](auth/ldap/ldap_synchronization.md#adjust-ldap-user-sync-schedule) To enable LDAP with the synchronization worker for Sidekiq: 1. Edit `/etc/gitlab/gitlab.rb`: ```ruby gitlab_rails['ldap_enabled'] = true gitlab_rails['prevent_ldap_sign_in'] = false gitlab_rails['ldap_servers'] = { 'main' => { 'label' => 'LDAP', 'host' => 'ldap.mydomain.com', 'port' => 389, 'uid' => 'sAMAccountName', 'encryption' => 'simple_tls', 'verify_certificates' => true, 'bind_dn' => '_the_full_dn_of_the_user_you_will_bind_with', 'password' => '_the_password_of_the_bind_user', 'tls_options' => { 'ca_file' => '', 'ssl_version' => '', 'ciphers' => '', 'cert' => '', 'key' => '' }, 'timeout' => 10, 'active_directory' => true, 'allow_username_or_email_login' => false, 'block_auto_created_users' => false, 'base' => 'dc=example,dc=com', 'user_filter' => '', 'attributes' => { 'username' => ['uid', 'userid', 'sAMAccountName'], 'email' => ['mail', 'email', 'userPrincipalName'], 'name' => 'cn', 'first_name' => 'givenName', 'last_name' => 'sn' }, 'lowercase_usernames' => false, # Enterprise Edition only # https://docs.gitlab.com/ee/administration/auth/ldap/ldap_synchronization.html 'group_base' => '', 'admin_group' => '', 'external_groups' => [], 'sync_ssh_keys' => false } } gitlab_rails['ldap_sync_worker_cron'] = "0 */12 * * *" ``` 1. Reconfigure GitLab: ```shell sudo gitlab-ctl reconfigure ``` ## Related topics - [Extra Sidekiq processes](operations/extra_sidekiq_processes.md) - [Extra Sidekiq routing](operations/extra_sidekiq_routing.md) - [Using the GitLab-Sidekiq chart](https://docs.gitlab.com/charts/charts/gitlab/sidekiq/) - [Sidekiq health checks](sidekiq_health_check.md)
