+# Gitlab
+
+## Docker Install
+
+```bash
+# Change the server's SSH port in /etc/ssh/sshd_config
+Port = 2424
+
+# Then tell selinux about it
+semanage port -a -t ssh_port_t -p tcp 2424
+# And add the firewall rule
+firewall-cmd --add-port=2424/tcp --permanent
+firewall-cmd --reload
+# Reload SSH
+systemctl restart sshd
+
+# Make a Gitlab directory
+mkdir -p /srv/gitlab
+
+# Add the following to .bashrc (used in the compose file)
+export GITLAB_HOME=/srv/gitlab
+```
+
+Create your `gitlab-compose.yaml`. See the file in this repo for an example.
+
+Also create the file `secrets/gitlab.rb` with your configuration. Should look something like this:
+
+```ruby
+# Add any other gitlab.rb configuration here, each on its own line
+external_url 'https://gitlab.reeseapps.com'
+nginx['listen_port'] = 80
+nginx['listen_https'] = false
+nginx['proxy_set_headers'] = {
+    "X-Forwarded-Proto" => "https",
+    "X-Forwarded-Ssl" => "on",
+    "Host" => "gitlab.mydomain.de",
+    "X-Real-IP" => "$$remote_addr",
+    "X-Forwarded-For" => "$$proxy_add_x_forwarded_for",
+    "Upgrade" => "$$http_upgrade",
+    "Connection" => "$$connection_upgrade"
+}
+gitlab_rails['smtp_enable'] = true
+gitlab_rails['smtp_address'] = "email-smtp.us-east-1.amazonaws.com"
+gitlab_rails['smtp_port'] = 465
+gitlab_rails['smtp_user_name'] = ""
+gitlab_rails['smtp_password'] = ""
+gitlab_rails['smtp_domain'] = ""
+gitlab_rails['smtp_authentication'] = "login"
+gitlab_rails['smtp_ssl'] = true
+gitlab_rails['smtp_force_ssl'] = true
+```
+
+Copy `gitlab.rb` and `gitlab-compose.yaml` to your server:
+
+```bash
+scp active/container_gitlab/gitlab-compose.yaml gitlab:
+scp active/container_gitlab/secrets/gitlab.rb gitlab:/srv/gitlab
+```
+
+Then docker compose up:
+
+```bash
+docker compose -f gitlab-compose.yaml up -d
+```
+
+The initial username is root and the password will be at `/srv/gitlab/config/initial_root_password`.
