Docker swarm php-fpm容器不断重启

Question

我创建了一个基本的 LAPP 堆栈，它运行在具有 docker-compose 的本地主机上完美无缺。当我尝试在生产服务器上使用 Swarm 实现运行（只有 1 个经理，没有工作人员）时，所有服务都会启动并被复制（1/1），但 php-fpm 服务会不断重启没有明显错误。

docker service ls

ID             NAME                    MODE         REPLICAS   IMAGE                  PORTS
p0rdrdfmso6x   traefik_reverse-proxy   replicated   1/1        traefik:v2.4           *:80->80/tcp, *:443->443/tcp
e6vwlo9iw2ny   my_stack_apache         replicated   1/1        apache:latest          *:8000->80/tcp
qy5yigbcjryr   my_stack_ftp            replicated   1/1        fauria/vsftpd:latest   *:20-21->20-21/tcp, *:22100-22110->22100-22110/tcp
n5f9v6bd2854   my_stack_php            replicated   0/1        php:latest
rcnbq4vnoz1j   my_stack_postgres       replicated   1/1        postgres:9.5.24

如果我们关注 php-fpm 容器：

docker service ps my_stack_php

ID             NAME                  IMAGE        NODE                        DESIRED STATE   CURRENT STATE             ERROR     PORTS
j6mp3ka40cyo   my_stack_php.1        php:latest   node.address                Ready           Ready 2 seconds ago
ezztpsjoglwy    \_ my_stack_php.1    php:latest   node.address                Shutdown        Complete 3 seconds ago
gnqjhwpi5y72    \_ my_stack_php.1    php:latest   node.address                Shutdown        Complete 9 seconds ago
0agr3tw0bb9g    \_ my_stack_php.1    php:latest   node.address                Shutdown        Complete 15 seconds ago
9a6wsdp4tqqn    \_ my_stack_php.1    php:latest   node.address                Shutdown        Complete 21 seconds ago

如果我查看日志： docker service logs my_stack_php

my_stack_php.1.igd8x7a6ysdi@node.address    | Interactive shell
my_stack_php.1.57td5iuk1wwy@node.address    | Interactive shell
my_stack_php.1.r03jn931l1uf@node.address    | Interactive shell
my_stack_php.1.igd8x7a6ysdi@node.address    |
my_stack_php.1.r03jn931l1uf@node.address    |
my_stack_php.1.1huf2pdd0bq0@node.address    | Interactive shell
my_stack_php.1.57td5iuk1wwy@node.address    |
my_stack_php.1.1huf2pdd0bq0@node.address    |

它的行为就像一个容器运行ning 一个将在几秒钟内以成功结束的命令。然后 Swarm 启动一个新容器来保持重启合约。但是，我的 php-fpm Dockerfile 提供了 -F 参数，应该保持进程运行ning :

PHP Dockerfile

# Run in foreground as root (in container POV)

有人知道这件事吗？任何 helps/tips 将不胜感激。
