This functionality can now be achieved via templates which was added in 1.8.0.

zombiemoose I think that this issue can be closed now..

Hmm, it sounds like new images are being generated whenever you run a new job? ingwar I'm not sure we solve that with templates since we would still be creating a new template for each new image, no?

digitalirony can you please verify this? You are generating a new image constantly and want to filter by image family in the configuration for the image you're going to launch your agent with?

Yes, I am running a job that uses packer.io to build GCE images from a 'recipe' I maintain in a git repo. 

I eventually want to be able to use my script to build several different flavors of my 'golden image', and tag them all using the os_family.

Then I can have This plugin always use the latest build automatically from that family. This way I am not constantly having to adjust which image jenkins uses for the slaves/agents. And I can just run my golden image builds, and know that jenkins will always pull the latest from the family specified if that makes sense?

And, no templates is not what I am looking for. zombiemoose

Ok, I see. I'm not sure how popular this use case would be, and that would affect how I prioritize this feature/if we do implement this feature.

I bet more people would use it if it was available. Is pretty handy.

digitalirony zombiemoose Thats exactly what Im telling about..

Thats was one of main reasons to add templates in our company.

At template level you can choose image family instead of image instead of image itself, and every time you create new image in that family it will automatically use it.

digitalirony Why don't you try out the template first and let me know what you think? I just tried it out via the command line in cloud console, and it did seem to give me the latest image in my image family.

Example:

gcloud compute instance-templates create example-template-custom \
    --machine-type n1-standard-4 \
    --image-family jenkins-agent \
    --image-project rach-project \
    --boot-disk-size 250GB

ingwar I was trying to create a template from cloud console, but it forces you to provide an image rather than just specifying an image family, so that's interesting. Thanks for your input.

We are using terraform + API directly to create templates (terraform and gcloud dont have such options)..

And seems like UI have only option to set image..

But via templates its possible to set every parameter of created machine (At least I did not found any parameter when its not possible)

ingwar Great to know. Thanks for your continued contributions! You've really helped us improve the plugin.
