Azure App Service using Docker Container, no newer official base images for Node

Question

Azure App Service using Docker Container, no newer official base images for Node

Lance H 21

We are currently using the Docker images from docker hub as a base for our own custom images using Azure App Service with containers.
The base images are located here: https://hub.docker.com/r/appsvc/node/tags

E.g. the first line of our Dockerfile:

FROM appsvc/node:14-lts_20200522.6

Unfortunately there have been no new images in at least 2 years, so there are no images for any node version greater than 14.

Is there any plan to produce newer node images for App Service?

Alternatively, is there any guidance or recommendation to a different approach?

@Lance H Microsoft has switched the hosting of our blessed images for App Services from Docker Hub to MCR/MAR. Please see here for more details on how to get started with MCR and our image hosting.

As you can see from this list, we have images for Node.js 16 and 18 so you should be good to switch since this sounds like what you were looking for.

Please let us know if you have any further questions or concerns.

Thanks for this - I actually stumbled upon the same list a few hours after posting but wasn't sure how official the images were.

They were rather hard to find - do you know why they aren't listed in the catalog at https://mcr.microsoft.com/en-us/ ?

Do you also know how to determine the full node version of an image without pulling it? I'm unsure if there are any Dockerfile's publically located with this information.

Hello @Lance H

This image FROM appsvc/node:14-lts_20200522.6 use Microsoft Oryx as the base images.
As you can see here the latest supported version of NodeJS Docker image is 14-lts. There is no sharable ETA of when 16 or 18 will be supported.
To stay updated on changes you may visit the Azure AppService team blog.

I would suggest to use official node 16,18 Docker images for Azure App Service custom container that is recommended by Microsoft

FROM node:16

Thanks for the advice. I'm not sure of the relevance of the Oryx comment - was there some reason for or against using the images based on their dependency on Oryx?

Are you able to advise the source of the "recommended by Microsoft" comment? I couldn't find any advice of this nature at all, though I swear that a year or two ago there was published advice (similar to https://learn.microsoft.com/en-us/azure/app-service/configure-custom-container?pivots=container-linux) regarding which base image to use for your own custom Node images, however there is nothing I can see anymore.
