▎Docker

手动安装

# 安装 Docker 依赖
apt update && apt install -y ca-certificates curl gnupg lsb-release

# 添加 Docker 官方 GPG 密钥
install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/$(. /etc/os-release; echo "$ID")/gpg | \
gpg --dearmor -o /etc/apt/keyrings/docker.gpg
chmod a+r /etc/apt/keyrings/docker.gpg

# 添加 Docker 软件源
echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] \
https://download.docker.com/linux/$(. /etc/os-release; echo "$ID") \
$(lsb_release -cs) stable" | tee /etc/apt/sources.list.d/docker.list > /dev/null

# 安装 Docker 和 Compose 插件
apt update && apt install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

# 启动 Docker 并设置开机自启
systemctl enable --now docker

# 检查是否安装成功：
docker --version
docker compose version

手动更新

docker ps

apt update

apt list --upgradable | grep -E 'docker|containerd'

apt install --only-upgrade -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

systemctl restart docker

docker ps

如果之前锁定过版本，先解除：

apt-mark unhold docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

更新后如果想重新锁住，避免以后 apt upgrade 顺手升级：

apt-mark hold docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

Compose 排版建议

1. image / build
2. container_name / hostname
3. restart
4. user / working_dir
5. command / entrypoint
6. networks
7. ports / expose
8. volumes
9. environment / env_file
10. depends_on
11. healthcheck
12. labels
13. logging
14. deploy / resources
15. privileged / cap_add / cap_drop / devices
16. sysctls / security_opt / ulimits / group_add
17. extra_hosts / dns / dns_search
