Podman容器端口绑定正常却无法通过localhost/主机IP访问求助

Podman容器Node.js服务无法通过localhost:443访问,但私有IP可连通的问题排查

我用Podman创建了运行Node.js Web服务器的容器,发现无法通过localhost:443访问容器服务,但能通过容器私有IP(如10.88.0.5:443)连通。

测试现象

访问私有IP的结果

执行命令:

curl https://10.88.0.5

返回:

curl: (60) SSL certificate problem: unable to get local issuer certificate
More details here: https://curl.se/docs/sslcerts.html

curl failed to verify the legitimacy of the server and therefore could not establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above

注:此失败仅因为SSL证书是为我的域名颁发的,但至少能确认网络已连通到网站服务。

访问localhost的结果

执行命令:

curl https://localhost --connect-timeout 5

返回:

curl: (28) SSL connection timeout

直接出现连接超时。

端口绑定验证

查看主机端口监听情况:

sudo netstat -tulp | grep https

输出显示443端口已被conmon监听:

tcp       12      0 0.0.0.0:https           0.0.0.0:*               LISTEN      4991/conmon 

Podman端口映射确认:

sudo podman port -l

输出:

443/tcp -> 0.0.0.0:443

容器配置文件(Containerfile)

FROM node:22.2.0
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
EXPOSE 443
CMD ["node", "."]

已明确暴露443端口。

已尝试的无效操作

  • 禁用UFW防火墙
  • 重新安装Podman

目前已排查4天仍未解决,求可行的解决方案或排查方向。

注:运行环境为最新版Debian系统。
