# Configurações de SElinux e FirewallD:

sed -i "s/SELINUX=enforcing/SELINUX=disabled/" /etc/selinux/config

sudo setenforce 0

# Vamos configurar o nosso Firewall:

sudo firewall-cmd --add-port=8080/tcp --permanent
sudo firewall-cmd --add-port=10051/tcp --permanent
sudo firewall-cmd --add-port=10050/tcp --permanent
sudo firewall-cmd --add-port=162/udp --permanent
sudo firewall-cmd --reload

# Os três primeiros comando é para instalar o docker e update do SO
sudo dnf config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
sudo dnf -y install docker-ce docker-ce-cli containerd.io
sudo usermod -aG docker $(whoami)
sudo systemctl enable --now docker

# Esse comando serve para criar o diretório onde irá ficar o docker-compose.yaml
sudo mkdir -p /home/zabbix/

# Agora é a criação do arquivo docker-compose.yaml
