Notification when new image pushed to docker hub

[Ewelina Wilkosz]

Hi!

I am trying to automate updating jenkins when new lts image is released

do you know:

1. if there is some notification mechanism in place? something I can "watch" and learn that new version is out?

2. I do not want to really go for "jenkins/jenkins:lts", I want to match lts to specific version. Anyone has an elegant way of getting, e.g. from docker hub, the information which other tags are applied to "lts" image?

not sure if docker hub or e.g. github is the right place to look for those information/event

it's a very general idea for now :) no specific technical solutions in place, checking what's available

Would this be for a production type instances of Jenkins or a personal instance?

well it wouldn't automatically, blindly try to apply it on production :)

the process I have in mind is:

1. new lts pushed to docker hub

2. I get notified/I monitor and discover it happened

3. I discover what is the actual version number for lts

4. I update my Dockerfile and build new docker image

I know I can pull the image and check the version e.g. with inspect, but I was wondering if it is possible to get the information without pulling, and if there is some notification mechanism in place

I have always had super good luck writing a go script job and incorporating https://github.com/crazy-max/diun

Most welcome!

So I usually just write a script that run this and then uses the built in email notification from a Jenkins job. Maybe not the most glorious way but it solves the immediate need.

Have a good rest of the week 🙂

I use dependabot that gives me a new pr for each version

Also I think this is better suited for the users list since this is not a question about developing Jenkins but using it

I hoped to get answer from people involved in jenkins release process and dev made sense for me
