#lax - October 2019

Hear from @Jake Lundberg (Coder) and his colleague next Thursday in Santa Monica!

@btai see this? https://www.meetup.com/lp/paymentchanges

oof I don’t like that @Erik Osterman (Cloud Posse)

I definitely don’t want our members pay to rsvp. at the same time I’d say our attendance rate is about 40~50% of the total rsvps

@btai @Corey Gale good tip yesterday at the meet up about setting up a pass thru registry for Docker to mitigate the effects of a Docker hub outage

I think mirroring the images to ECR is a PIA

But in researching this some more, I learned about the registry mirror option built into Docker

Pia?

Looks like this is natively supported by Kops

So it seems like it’s easy enough to deploy a pass thru registry in cluster and then configure the mirror to use it

Not sure what happens if the mirror is offline - I presume it attempts upstream

@Corey Gale has joined the channel

@Jeremy G we should add this to next rollout

Maybe go all the way and use something like Artifactory to be the pull-through cache for everything, not just docker images. https://jfrog.com/artifactory/features/

I just don’t know where the line is drawn between open source and enterprise. Artifactory is cool and all, but I know their pricing is insane.

@Erik Osterman (Cloud Posse) is there a big difference in registry mirroring vs just pushing to 2 different registries?

you could do them in parallel in ci step (push to codefreshf registry + push to ECR)

chances are you don't rely on just your software

in our case: prometheus, grafana, keycloak, gatekeeper, kubecost, and 2 dozen other third-party vendors

sure you can take on the burden of pushing those to your own repos - that's great (but a lot of work)

or you can just use a mirror that that has a pull-through cache (as you describe) and address the immediate risk of being crippled by upstream outages.

I'd argue:

1) from a security perspective, you should explicitly replicate or produce an image in your own repo for every package you depend on. for smaller team, this might be a lot of overhead. it will shield you also from upstream outages.

2) from an HA perspective, the registry mirror is sufficient.

80/20 rule

option (1) is 80% more work with 20% more benefit

👍️ great response erik
