AZ Lamps #9 — Container Registry Cache
Azure recently equipped Container Registry (ACR) with a new Cache feature, which caught my attention. To remind you — ACR is a private repository for docker images. I wrote about this service earlier on my channel (check out the tag #acr).
The feature allows you to cache images from other repositories, such as DockerHub. The improvement may seem trivial initially, but I can’t agree for two reasons.
1. Image pull will speed up because we can use an internal virtual network instead of the internet. As a result, complex microservices-rich ecosystems will see a significant improvement.
2. Eliminating an external resource dependency (DockerHub) improves overall reliability. It’s worth drawing an analogy with nuget.org — I have often seen how its inaccessibility completely blocked development.
The feature is now in preview, but I sincerely hope it will go to GA soon. Little things like Container Registry Cache are what make perfection.
