1. Install Docker
1.1. Install Docker with the script
# Download docker installer script:
curl -fsSL https://get.docker.com -o get-docker.sh
# Install docker by 'get-docker.sh' script:
DRY_RUN=1 sudo sh get-docker.sh
# Remove downloaded script:
rm -vrf get-docker.sh
# To avoid using 'sudo' for docker commands:
# Create a new 'docker' group:
sudo groupadd docker
# Add current user to the 'docker' group:
sudo usermod -aG docker $(whoami)
# Apply new group changes to the new shell session:
newgrp docker
# Or reboot the system to apply docker group changes:
sudo shutdown -r now
# Configure docker to start on reboot:
sudo systemctl enable docker.service
sudo systemctl enable containerd.service
# Check docker is installed and running:
docker -v
docker info
docker images
1.2. [Only for GPU] Install NVIDIA Docker
- Skip this step, if you don't have NVIDIA GPU!
- [REQUIRED] Install NVIDIA GPU driver: https://github.com/bybatkhuu/wiki/blob/main/posts/manuals/installs/nvidia-driver-linux.md
- For Ubuntu/Debian-based Linux distros:
## [IMPORTANT] Only for Ubuntu/Debian-based linux
# Download the nvidia-docker GPG key and setup the stable repository:
distribution=$(. /etc/os-release;echo $ID$VERSION_ID) \
&& curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | sudo apt-key add - \
&& curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.list | sudo tee /etc/apt/sources.list.d/nvidia-docker.list
# Update repository list:
sudo apt-get update
# Install nvidia-docker2:
sudo apt-get install -y nvidia-docker2
Edit the /etc/docker/daemon.json file:
sudo nano /etc/docker/daemon.json
and add the following default-runtime into the /etc/docker/daemon.json file:
{
"default-runtime": "nvidia"
}
For example:
{
"default-runtime": "nvidia",
"runtimes":
{
"nvidia":
{
"path": "nvidia-container-runtime",
"runtimeArgs": []
}
}
}
save changes and exit from the file editor.
# Restart docker service:
sudo systemctl daemon-reload
sudo systemctl restart docker.service
2. [RECOMMENDED] Limit docker log file max size and max rotation
Edit the /etc/docker/daemon.json file:
sudo nano /etc/docker/daemon.json
and add the following log-opts into the /etc/docker/daemon.json file:
{
"log-opts":
{
"max-size": "10m",
"max-file": "10"
}
}
save changes and exit from the file editor.
# Restart docker service:
sudo systemctl restart docker.service
3. Install Docker Compose V2
## Download docker-compose binary release:
# [RECOMMENDED] Compose v2.2.3 (Linux) release:
sudo curl -L "https://github.com/docker/compose/releases/download/v2.2.3/docker-compose-linux-$(uname -m)" -o /usr/local/bin/docker-compose
# [For old version] Compose v1.29.2 (Linux) release:
# 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
# [Only for experimental] Latest version release:
# sudo curl -L $(curl -s https://api.github.com/repos/docker/compose/releases/latest | grep browser_download_url | grep linux-$(uname -m)\" | cut -d '"' -f 4) -o /usr/local/bin/docker-compose
# Apply executable permission to the docker-compose binary:
sudo chmod +x /usr/local/bin/docker-compose
# Create a symbolic link to '/usr/bin':
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
# Check docker-compose version:
docker-compose --version
👍 ✨
INSTALLATION COMPLETE
[OPTIONAL] Change the docker data directory to the external storage
# Stop the docker service:
sudo systemctl stop docker.service
Edit the /etc/docker/daemon.json file:
sudo nano /etc/docker/daemon.json
and add the following data-root into the /etc/docker/daemon.json file (don't forget to change [NEW_STORAGE_PATH] to your new directory):
{
"data-root": "[NEW_STORAGE_PATH]/docker/data-root"
}
For example:
{
"data-root": "/mnt/ssd/1/docker/data-root"
}
save changes and exit from the file editor.
# Copy the current docker data directory to the new directory:
sudo rsync -a /var/lib/docker/ [NEW_STORAGE_PATH]/docker/data-root
# For example:
sudo rsync -a /var/lib/docker/ /mnt/ssd/1/docker/data-root
# Rename the old docker data directory as a backup:
sudo mv /var/lib/docker /var/lib/docker.old
# Start docker service:
sudo systemctl start docker.service
# Test docker is working properly:
docker -v
docker info
docker images
docker ps -a
# Remove the old backup docker data directory:
sudo rm -rf /var/lib/docker.old
[OPTIONAL] Install command auto-completion for docker-compose
# Download docker-compose auto-completion script into '/etc/bash_completion.d/':
sudo curl \
-L https://raw.githubusercontent.com/docker/compose/1.29.2/contrib/completion/bash/docker-compose \
-o /etc/bash_completion.d/docker-compose
# Reload current bash shell session:
source ~/.bashrc
