Deploy automático com Bitbucket

README.md

#Preparando ambiente

Primeiramente você precisará da chave pública do seu servidor para poder se comunicar com o Bitbucket usando SSH sem senha. Esta chave geralmente fica no caminho:

/home/user/.ssh/id_rsa.pub

Caso a pasta .ssh não exista no diretório home do usuário, basta executar o comando ssh-keygen. Copie o conteúdo do arquivo id_rsa.pub e adicione no seu repositório em Settings > Deployment Keys.

#Clonando repositório

Clonar o projeto na pasta raiz do virtualhost

Configurando webhook

Agora vá até as configurações do seu repositório e configure o Webhook em Settings > Webhook > Add webhook. Defina um título pra ele, na URL insira o caminho do arquivo PHP http://meudominio.com/deploy.php e defina quando ele deve ser invocado. O padrão é ser invocado sempre que houver um push no repositório.
