Install Docker and Docker Compose#

Update and install necessary software

apt-get update && apt-get install -y wget vim

Install Docker for non-mainland users

wget -qO- get.docker.com | bash

Note: If "sudo: unable to resolve host [hostname]" appears, you can edit nano /etc/hosts and then add a space after localhost, followed by the content of your corresponding hostname.

Check Docker version

Uninstall Docker

sudo apt-get purge docker-ce docker-ce-cli containerd.io
sudo rm -rf /var/lib/docker
sudo rm -rf /var/lib/containerd

Install Docker Compose for non-mainland users

sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

Check if installed docker-compose --version

Modify Docker configuration (from Shao Bing's blog) https://u.sb/debian-install-docker/
The following configuration will add a custom internal IPv6 address, enable IPv6 functionality for containers, and limit the size of log files to prevent Docker logs from filling up the hard drive:

cat > /etc/docker/daemon.json <<EOF
{
    "log-driver": "json-file",
    "log-opts": {
        "max-size": "20m",
        "max-file": "3"
    },
    "ipv6": true,
    "fixed-cidr-v6": "fd00:dead:beef:c0::/80",
    "experimental":true,
    "ip6tables":true
}
EOF

Then restart the Docker service: systemctl restart docker
