docker-compose version # 验证docker compose版本

3、安装为docker compose（新版v2插件模式安装，Docker CLI）

DOCKER_CONFIG=${DOCKER_CONFIG:-$HOME/.docker} # 插件安装到 ~/.docker/cli-plugins/
mkdir -p $DOCKER_CONFIG/cli-plugins
cp docker-compose-linux-x86_64 $DOCKER_CONFIG/cli-plugins/docker-compose
chmod +x $DOCKER_CONFIG/cli-plugins/docker-compose
docker compose version
