Question

我正在尝试在本地计算机上运行Vulas docker安装程序。我遵循了这个guide。当我执行文档的“运行”阶段时，后端服务无法启动。进程启动时，它们将返回以下错误：

它似乎表明一个.env问题，但是，它的配置如安装指南中所述。我的.env是：

# Vulas
VULAS_RELEASE=3.0.15
VULAS_ENV=prod

# *** MANDATORY SETTINGS ***
# PostgreSQL
POSTGRES_USER=admin
POSTGRES_PASSWORD=secret

# Spring (should be equal to the values in PostgreSQL section above)
spring.datasource.username=admin
spring.datasource.password=secret

# HAProxy
HAPROXY_STATS_USER=admin
HAPROXY_STATS_PASSWORD=secret

# Frontend Bugs Frontend
FRONTEND_BUGS_USER=admin
FRONTEND_BUGS_PASSWORD=secret

# *** OPTIONAL SETTINGS ***
# Jira (optional)
JIRA_USER=
JIRA_PASSWORD=

# Proxy
HTTP_PROXY_HOST=
HTTPS_PROXY_HOST=
HTTP_PROXY_PORT=
HTTPS_PROXY_PORT=
NON_PROXY_HOSTS=
http_proxy=
https_proxy=
no_proxy=

我尝试了this，但没有成功！

从以上评论中，我可以了解到您的.env文件存在问题。基本上，在您的.env中，VULAS_RELEASE被设置为3.0.15，但是可能您构建了标记为3.0.15-SNAPSHOT版本的工件。

一般规则是始终检查VULAS_RELEASE中的.env.sample，并在自定义.env中使用该值。

还要考虑到，在每个发行版中VULAS_RELEASE都会递增，因此，每次您提取较新发行版中的代码时，都必须更新.env。

Vulas后端无法连接到数据库
