Could I just use an image to host an app on epinio? And bypass the buidpack step, is that what --container-image-url provide?

that's correct 🙂 you can try with

epinio app push --container-image-url "splatform/sample-app" -n sample

can I tell it which port to open?

I was able to deploy it this way, but the wrong port is exposed unfortunately

@bulky-church-2468 you mean the container port? https://github.com/epinio/helm-charts/blob/main/chart/application/templates/deployment.yaml#L39

the ports are hardcoded in the default application helm chart (see the link) but there is a

PORT

environment variable available that you can use to tell the app to listen there

oh ok, so passing PORT=PORTNUMBER as env variable will do the tricks

got it

no, the other way around. So your app should start listening to the

PORT

env var. In your code you should have something like

os.GetEnv("PORT")

or similar

hmmm I see, I can’t change the port, it’s exposed in the docker image, would be better if we could configure the port mapping on the service somehow

even if we made it configurable in the application helm chart, it would still require this story to configure it: https://github.com/epinio/epinio/issues/1252

in the meantime, you can clone the application helm chart, make a hardcoded change to the desired port and create a custom application chart with your new version. Let me send you some links

docs: https://docs.epinio.io/howtos/create_custom_appcharts

this should be enough I think. You will be able to use your custom app chart then with that application

seems doable, coming from rio, I miss that riofile features where I could enjoy rio default values and merge my own

seems more adventurous here, submitting another application chart and assigning it to a specific app

could not find anything in the docs pointing to that solution

Well what I suggested is a temporary hack to unblock you. The actual solution is the open issue I sent above (1252)

There you would be able to pass values and merge them with the defaults from the chart
