+# Gitea Actions Runner — Dockerino
+
+Este diretório contém a configuração do runner de Gitea Actions para executar workflows CI/CD.
+
+## Visão Geral
+
+O **act_runner** é o agente que executa os jobs definidos nos workflows `.gitea/workflows/*.yml`. Ele roda no Dockerino (10.0.0.50) usando Docker.
+
+## Arquivos
+
+```
+gitea-runner/
+├── docker-compose.yml   # Serviço do runner
+├── config.yaml          # Configuração (gerado no registro)
+├── register.sh         # Script de registro
+└── data/               # Dados persistentes do runner
+```
+
+## Instalação
+
+### 1. Obter Token de Registro
+
+Acesse o Gitea como admin:
+```
+https://gitea.hackerfortress.cc/admin/runners
+```
+
+Clique em **"New Runner"** e copie o token.
+
+### 2. Registrar o Runner
+
+```bash
+cd gitea-runner
+export RUNNER_TOKEN="seu-token-aqui"
+./register.sh
+```
+
+### 3. Iniciar o Runner
+
+```bash
+docker compose up -d
+```
+
+### 4. Verificar
+
+Acesse:
+```
+https://gitea.hackerfortress.cc/admin/runners
+```
+
+O runner deve aparecer como **"Active"**.
+
+## Labels Disponíveis
+
+| Label | Descrição |
+|-------|-----------|
+| `gitea-runner-dockerino` | Runner principal |
+| `ubuntu-latest` | Container Ubuntu para jobs |
+
+## Troubleshooting
+
+### Runner não aparece como active
+
+```bash
+# Ver logs
+docker compose logs -f act_runner
+
+# Verificar configuração
+cat config.yaml
+```
+
+### Docker socket permission denied
+
+```bash
+# No host (Dockerino), adicionar usuário ao grupo docker
+sudo usermod -aG docker $USER
+```
+
+### Jobs ficam em "Pending"
+
+- Verificar se runner está online
+- Verificar se o token está correto
+- Verificar se o runner tem labels necessárias
+
+## Atualização
+
+```bash
+cd gitea-runner
+docker compose pull
+docker compose up -d
+```
