请教一下服务启动依赖顺序问题 #1232

Closed cgfeel closed 1 year ago

cgfeel commented 2 years ago

在docker-production.online.yml中我启用两个php服务php7和php8，并启用一个nginx服务，将nginx服务依赖于php：

    depends_on:
      - php7
      - php8

在启动服务的时候$ ./lnmp-docker swarm-deploy，有的时候并非按照顺序执行，就会造成启动服务失败

Creating network lnmp_backend
Creating network lnmp_frontend
...
Creating service lnmp_nginx
Creating service lnmp_redis
Creating service lnmp_php8
Creating service lnmp_php7

打印启动失败容器的日志，提示没有找到php7这项服务

$ docker logs c1b700273884
2022/07/03 16:58:03 [emerg] 1#1: host not found in upstream "php7" in /etc/nginx/conf.d/51baopen.com.conf:17
nginx: [emerg] host not found in upstream "php7" in /etc/nginx/conf.d/51baopen.com.conf:17

于是我把服务关了，重新启动就好了

$ docker stack rm lnmp
$ ./lnmp-docker swarm-deploy
Creating service lnmp_redis
Creating service lnmp_php8
Creating service lnmp_php7
Creating service lnmp_nginx

g1h0osyd5pca   lnmp_php8.1    khs1994/php:8.1.1-s6-alpine    VM-20-14-debian   Running         Running 4 seconds ago

有的时候需要重启好几次才对，请问这个问题需要怎样解决

Recommend use wait4x or wait-for-it.
