Set Domain Name

export USE_HOSTNAME=nama_domain.go.id \
&& echo $USE_HOSTNAME > /etc/hostname \
&& hostname -F /etc/hostname

Install the latest updates

Ubuntu

apt-get update && apt-get upgrade -y

CentOS

yum update -y \
yum upgrade

1. Download dan Install Docker

mkdir -p /opt/docker \
&& cd /opt/docker \
&& curl -fsSL get.docker.com -o get-docker.sh \
&& CHANNEL=stable sh get-docker.sh

Configure Docker to start on boot

sudo systemctl enable docker && sudo systemctl start docker

2. Install Docker-Compose (Skip jika mengggunakan docker swarm)

sudo curl -L "https://github.com/docker/compose/releases/download/1.24.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

Test Docker Installation

docker --version \
&& docker run hello-world

3. Test Instalasi Docker-Compose

docker-compose --version

Set Docker Experimental

echo $'{\n    "experimental": true\n}' | sudo tee /etc/docker/daemon.json;
systemctl restart docker

cek status experimental

docker version -f '{{.Server.Experimental}}'

Tuning virtual machines Edit /etc/sysctl.conf dengan menambahkan

vm.max_map_count=262144

atau eksekusi perintah

sudo sysctl -w vm.max_map_count=262144

Cek vm.max_map_count

sysctl vm.max_map_count

mkdir -p /etc/systemd/system/docker.service.d/ \
&& touch /etc/systemd/system/docker.service.d/10-machine.conf \
&& sudo sed -i '/ExecStart=\/usr\/bin\/dockerd/ s/$/--default-ulimit memlock=-1/' /etc/systemd/system/docker.service.d/10-machine.conf

akan terbentuk file override.conf pada /etc/systemd/system/docker.service.d

echo -e "[Service]\nLimitMEMLOCK=infinity" | SYSTEMD_EDITOR=tee systemctl edit docker.service \
&& systemctl daemon-reload && systemctl restart docker

reboot
