Continuous Deployment with Shiny Proxy about shinyproxy

[fmichielssen]

Updating an app is indeed possible without downtime, by building a new docker image. ShinyProxy will automatically use the latest image build, unless you specify an image version in your yml.

Adding new apps is not possible, however, because reloading the yml at runtime is a tricky concept. It makes sense for the apps section, but other config is not straightforward to re-apply; e.g. the authentication-related sections.

That being said, we are trying to add more flexibility in this regard in the next major release of ShinyProxy. There will be support for runtime parameters, such as the amount of RAM a proxy is allowed to use. It will also be possible to launch a custom app spec, but the details of this have not yet been drawn out.

update the app should basically no problem I guess because that's how shiny itself works. However, publishing a new app w/o interrupting is in doubt. I remember that shinyproxy do not support ad-hoc reloading the application.yml.

Well, I'm not the expert. Welcome to correct me...

No, it's not possible with this release:

You’re right. I forgot the app in shinyproxy is bundle into the docket image. It’s the shinyserver that can update / add the apps in real-time.

Thanks for all the replies. Good to know that building new docker image updates an existing app and the current difficulties in updating yml on the fly. Look forward to the next major release!
