Architecture confusion (arm64 vs arm64/v8) #28

Closed rueckix closed 5 years ago

rueckix commented 5 years ago

I am having trouble with pulling images on raspberry pi 3B.

If I pull the master-alpine tag, it works perfectly. Trying to pull the latest-alpine, results in errors (no matching manifest...).

I did a bit of digging and found that my architecture is advertised by docker as "linux/arm64/v8" and that your images are built for "linux/arm64", i.e., not specifying the "v8". Similarly, in the Dockerfile for Alpine, there is a substring check for "arm64" that will not work if "v8" is present in $TARGETPLATFORM.

What do you think, could this be causing the issues that I am observing? If so, I am wondering why it would work on master.

Let me add more details.

no matching manifest for linux/arm64/v8 in the manifest list entries

Hi @rueckix,

The reason it works on the master images is because those are the only images that have the arm64 manifests.

The latest and X.X.X tags are still pointing to the old images that were built before I added support for arm64. Since I added that support there haven't been any new releases of octoprint, which is why they haven't been auto-updated. (you can confirm this from the timestamps here)

I'll kick off a build to update latest and 1.3.11 right now.

Thanks, I'll keep an eye out for those new builds. Great work, by the way.

nunofgs commented 5 years ago

Builds are pushed. Give it a whirl!

rueckix commented 5 years ago

Just fired up "alpine". Works. Found that "latest-alpine" does not exist, though (listed in the the Readme.md).

nunofgs commented 5 years ago

Nice catch, the README is incorrect. latest-alpine is just alpine (same for debian)
