添加docker用户组(存在则跳过)

groupadd docker

Docker 的 systemd 服务文件

下载 Docker 的 systemd 服务文件，也可使用后续步骤进行创建。

#下载 Docker 的 systemd 服务文件，也可使用后续步骤进行创建
https://raw.githubusercontent.com/moby/moby/master/contrib/init/systemd/docker.service

https://raw.githubusercontent.com/moby/moby/master/contrib/init/systemd/docker.target

#下载 containerd 的 systemd 服务文件，也可使用后续步骤进行创建
https://raw.githubusercontent.com/containerd/containerd/main/containerd.service

docker.service

创建/etc/systemd/system/docker.service，内容如下：

[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target firewalld.service containerd.service time-set.target
Wants=network-online.target containerd.service
# Requires=docker.socket

[Service]
Type=notify
# the default is not to use systemd for cgroups because the delegate issues still
# exists and systemd currently does not support the cgroup feature set required
# for containers run by docker
ExecStart=/usr/bin/dockerd
ExecReload=/bin/kill -s HUP $MAINPID
TimeoutStartSec=0
RestartSec=2
Restart=always

# Note that StartLimit* options were moved from "Service" to "Unit" in systemd 229.
# Both the old, and new location are accepted by systemd 229 and up, so using the old location
# to make them work for either version of systemd.
StartLimitBurst=3

# Note that StartLimitInterval was renamed to StartLimitIntervalSec in systemd 230.
# Both the old, and new name are accepted by systemd 230 and up, so using the old name to make
# this option work for either version of systemd.
StartLimitInterval=60s

# Having non-zero Limit*s causes performance problems due to accounting overhead
# in the kernel. We recommend using cgroups to do container-local accounting.
LimitNPROC=infinity
LimitCORE=infinity

# Comment TasksMax if your systemd version does not support it.
# Only systemd 226 and above support this option.
TasksMax=infinity

# set delegate yes so that systemd does not reset the cgroups of docker containers
Delegate=yes

# kill only the docker process, not all processes in the cgroup
KillMode=process
OOMScoreAdjust=-500

[Install]
WantedBy=multi-user.target

修改权限：

chmod +x /etc/systemd/system/docker.service

containerd.service

创建/etc/systemd/system/containerd.service，内容如下：

修改文件权限：

chmod +x /etc/systemd/system/containerd.service

启动docker

systemctl daemon-reload 

systemctl enable containerd
systemctl start containerd

systemctl enable docker
systemctl start docker

安装docker-compose

在https://github.com/docker/compose/releases下载docker-compose-linux-x86_64,下载完成后，移动至/usr/local/bin目录下

mv docker-compose-linux-x86_64 /usr/local/bin/docker-compose
# 修改权限
sudo chmod +x /usr/local/bin/docker-compose

在容器中使用英伟达驱动

前提条件

• 主机已安装英伟达驱动、CUDA-Toolkit等相关软件；
• 一台联网电脑

下载nvidia-container-toolkit

curl -s -L https://nvidia.github.io/libnvidia-container/stable/rpm/nvidia-container-toolkit.repo | sudo tee /etc/yum.repos.d/nvidia-container-toolkit.repo

sudo yum-config-manager --enable nvidia-container-toolkit-experimental

sudo yum install --downloadonly --downloaddir=/root/mypackages/ nvidia-container-toolkit #该命令会下载nvidia-container-toolkit及其依赖

安装nvidia-container-toolkit

由于存在依赖关系建议使用以下顺序进行安装：

sudo yum install libnvidia-container1-1.13.5-1.x86_64.rpm -y
sudo yum install libnvidia-container-tools-1.13.5-1.x86_64.rpm -y
sudo yum install nvidia-container-toolkit-base-1.13.5-1.x86_64.rpm -y
sudo yum install nvidia-container-toolkit-1.13.5-1.x86_64.rpm -y

sudo nvidia-ctk runtime configure --runtime=docker

sudo systemctl daemon-reload
sudo systemctl restart docker

问题

driver rpc error: timed out

如果出现nvidia-container-cli: initialization error: driver rpc error: timed out问题，使用以下命令开启gpu持续模式：

nvidia-smi -pm ENABLED
