Docker swarm php-fpm 容器不断重启

问题描述

我创建了一个基本的 LAPP 堆栈，它使用 docker-compose 在本地主机上完美运行。当我尝试让它在生产服务器上与 Swarm 一起运行时（只有 1 个经理，没有工作人员），所有服务都会启动并被复制（1/1），但是 PHP-fpm 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

如果我们专注于 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

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

[e-mail]    | Interactive shell
[e-mail]    | Interactive shell
[e-mail]    | Interactive shell

它的行为就像一个运行命令的容器，该命令将在几秒钟内以成功结束。 Swarm 然后启动一个新容器来保持重启合约。但是，我的 PHP-fpm Dockerfile 提供了应该保持进程运行的 -F 参数：

PHP Dockerfile

我不喜欢这种回答，但副本在完全重启后全部上线。
