Como fazer deploy na digital ocean com github actions

Github Actions Digital Ocean Deploy.md

1. Primeiro crie uma chave ssh para deploy que será salva no github actions para ter acesso a maquina da digital ocean 1.1 Crie utilizando esses steps https://docs.github.com/en/github/authenticating-to-github/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent
2. Adicione ssh.publica no servidor no arquivo authorized_keys
3. Adiciona o ssh ao repositório do github nas settings do repositório 3.1 Caso possua pacotes privados do github não esqueça de configrar o .npmrc na pasta do package.json setando token de leitura para instalação de packages do repositório do gitbub

3.3 Adicione as configurações de conexão ssh utilizando as enviroments do repositório seguindo padrão de prefixo no nome SSH SSH_HOST -> ip da maquina SSH_PORT -> porta ssh 22 SSH_KEY -> chave ssh utilizada para conectar na maquina SSH_USERNAME -> nome de usuário root
