## Em um Sistema Linux Debian
### 1. Apague eventuais versões anteriores do Docker
`apt update`
```
apt update
```
`apt remove docker docker-engine docker.io containerd runc`
```
apt remove docker docker-engine docker.io containerd runc
```
### 2. Instale os pacotes e dependências necessários para o apt utilizar os repositórios via HTTPS:
`apt install ca-certificates curl gnupg lsb-release`
```
apt install ca-certificates curl gnupg lsb-release
```
### 3. Adicione a chave GPG oficial do Docker:
`install -m 0755 -d /etc/apt/keyrings`
```
install -m 0755 -d /etc/apt/keyrings
```
`curl -fsSL https://download.docker.com/linux/debian/gpg | gpg --dearmor -o /etc/apt/keyrings/docker.gpg`
```
curl -fsSL https://download.docker.com/linux/debian/gpg | gpg --dearmor -o /etc/apt/keyrings/docker.gpg
```
### 4. Configure o repositório de acordo com sua distribuição e arquitetura:
`echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/debian $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | tee /etc/apt/sources.list.d/docker.list > /dev/null`
```
echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/debian $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | tee /etc/apt/sources.list.d/docker.list > /dev/null
```
### 5. Atualize novamente a lista de pacotes do repositório e instale os pacotes necessários:
`apt update`
```
apt update
```
`apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin`
```
apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
```
### 6. Verifique se deu tudo certo exibindo o status do serviço Docker, a versão do Docker e do Docker Compose:
`systemctl status docker`
```
systemctl status docker
```
`docker –-version`
```
docker –-version
```
`docker compose version`
```
docker compose version
```
### Dica Extra (bastante utilizada em Sistemas que utilizam Docker)
Para não precisar utilizar o docker sempre como root, dê permissões de iniciar, parar e manipular contêineres a usuários comuns específicos:
`usermod -aG docker usuario_comum`
```
usermod -aG docker usuario_comum
```
