我正在Kubernetes中部署一个有istio-ingress的闪亮服务器。我们也安装了一个正常工作的ingressgateway。
但当我试图通过网关访问我闪亮的服务器时，它以400坏请求失败。网关已使用https启用。我尝试了多次修改shiny-server.conf文件和shiny-server的virtualservice.yml，但没有成功。我甚至不知道如何进行进一步的故障排除。
请帮忙。
shinyserver应用的Dockerfile

COPY /app /srv/shiny-server/executive/
EXPOSE 80
COPY shiny-server.conf /etc/shiny-server/shiny-server.conf
CMD ["/usr/bin/shiny-server.sh"]
Shiny-server.conf文件：
# Define the user we should use when spawning R Shiny processes
run_as shiny;
# Define a top-level server which will listen on a port
server {
# Instruct this server to listen on port 80. The app at dokku-alt need expose PORT 80, or 500 e etc. See the docs
listen 80;
# Define the location available at the base URL
location / {
# Run this location in 'site_dir' mode, which hosts the entire directory
# tree at '/srv/shiny-server'
app_dir /srv/shiny-server/executive;
# Define where we should put the log files for this location
log_dir /var/log/shiny-server;
# Should we list the contents of a (non-Shiny-App) directory when the user
# visits the corresponding URL?
directory_index off;

现在，当我试图从我们系统中下面URL的网关访问它时，它失败了，出现了400个坏请求。https://10.20.33.134:32000/executive/
需要一些帮助来确定原因或我应该采取的方向。
谢谢和问候。
它现在似乎正在工作。我忘了在我最新的Dockerfile中添加httpuv包。添加此包后，它开始工作。
谢谢。
