安装

1.Set up Docker's Apt repository.

# Add Docker's official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl gnupg
sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg

# Add the repository to Apt sources:
echo \
  "deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
  "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update

2.Install the Docker packages.

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

3.Verify that the Docker Engine installation is successful by running the hello-world image.

sudo docker run hello-world

卸载

1.Uninstall the Docker Engine, CLI, containerd, and Docker Compose packages:

sudo apt-get purge docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin docker-ce-rootless-extras

2.Images, containers, volumes, or custom configuration files on your host aren't automatically removed. To delete all images, containers, and volumes:

sudo rm -rf /var/lib/docker
sudo rm -rf /var/lib/containerd

后续步骤

1.Create the docker group.

sudo groupadd docker

2.Add your user to the docker group.

sudo usermod -aG docker $USER

3.You can run the following command to activate the changes to groups(激活用户组):

newgrp docker

4.Verify that you can run docker commands without sudo.

docker run hello-world

5.配置阿里镜像加速:

sudo service docker stop

sudo mkdir -p /etc/docker

sudo vim /etc/docker/daemon.json

{
    "registry-mirrors": ["https://gyd30bw2.mirror.aliyuncs.com"],
    "bip": "172.0.0.1/24"
}

Tips: bip:设置docker的ip,防止与本机ip冲突,避免ip访问服务异常

6.docker参数配置重新加载+重启

sudo systemctl daemon-reload
sudo systemctl restart docker

7.Access an NVIDIA GPU

确保已经安装了显卡驱动，查看本机显卡驱动信息执行如下:

nvidia-smi

nvidia-smi

安装nvidia-container-runtime:

sudo apt-get install nvidia-container-runtime

确保可以查询到nvidia-container-runtime-hook

which nvidia-container-runtime-hook

调用GPU创建容器:

docker run -it --rm --gpus '"device=0,2"' ubuntu nvidia-smi

效果如下:

container: nvidia-smi

8.查看容器映射路径:

docker inspect dockertest | grep Mounts -A 20
