Hướng dẫn cài đặt Docker

Với Ubuntu 22.04

Cài đặt Docker

apt-get update
apt-get install ca-certificates curl gnupg lsb-release -y
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | tee /etc/apt/sources.list.d/docker.list > /dev/null

Cài đặt Docker Engine

apt-get update
apt-get install docker-ce docker-ce-cli containerd.io -y
chmod 666 /var/run/docker.sock
systemctl restart docker && systemctl enable docker

Cài đặt Docker Compose

curl -L "https://github.com/docker/compose/releases/download/v2.6.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
docker-compose -v

Với Debian

Thiết lập Apt Repo của Docker

Add GPG Key chính thức của Docker:

apt-get update
apt-get install ca-certificates curl gnupg -y
install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/debian/gpg | gpg --dearmor -o /etc/apt/keyrings/docker.gpg
chmod a+r /etc/apt/keyrings/docker.gpg

Add repo:

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
apt-get update

Cài đặt Docker Engine

apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

Cài đặt Docker Compose

curl -SL https://github.com/docker/compose/releases/download/v2.20.3/docker-compose-linux-x86_64 -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

Proxy Server cho Docker

Nếu sử dụng proxy, hãy gắn Proxy Server cho Docker (giả sử proxy 10.237.7.250 và TCP/3128)

mkdir -p /etc/systemd/system/docker.service.d
cat > /etc/systemd/system/docker.service.d/http-proxy.conf << 'OEF'
[Service]
Environment="HTTP_PROXY=http://10.237.7.250:3128" "HTTPS_PROXY=http://10.237.7.250:3128" "NO_PROXY=localhost,127.0.0.1,docker-registry.somecorporation.com"
OEF

systemctl daemon-reload
systemctl restart docker
