APK v3

henderkes

When trying to connect an alpine client (3.20+) to a ProGet apk repo, you get errors about the unsupported v2 format of the repo. Alpine 3.20+ only supports v3, while <=3.19 support both v2 and v3.

Hi @henderkes,

Based on the Alpine's Package Keeper documentation, although the apk-tools are at version 3, the index and packages are still v2. From what I can tell, there is no timeline on when the v2 Index format will be dropped and the use of the v3 index is an opt-in feature. Currently ProGet only supports the v2 index and package format. I have added apk V3 support to be reviewed for ProGet 2026.

Could you please provide a little more details around what operations are giving you the errors and the log output that shows the error?

Thanks,
Rich

@rhessinger Hi, thanks for the quick response. I set up an Alpine repo on ProGet and uploaded one package to it. Set up docker with alpine:latest and alpine:3.20 and both times got a message about v2 formats not being supported any longer when trying to apk add php-zts-cli.

Additionally, if I add more than one package to the repository, on 3.19, apk only sees the first uploaded package to a feed. If I use native builds on the other hand, apk works on :latest too and finds all packages.

I'll post exact replication instructions and share the packages in question later.

Alright here we go. First issue: trying to use the endpoint that proget advertises:

for file in *; do
curl http://localhost:8624/apk/alpine-test/ --user Admin:Admin --upload-file "$file"
done

Results in Endpoint not available at this url.. The correct url does not have a trailing slash, I'm not sure why proget advertises it with one.

After uploading correctly, we can run a Docker container:

[m@M m]$ docker run -it --network host alpine:latest sh
/ # apk add wget nano curl
wget -O "/etc/apk/keys/alpine-test@proget.rsa.pub" http://localhost:8624/apk/alpine-test/keys/alpine-test%40proget.rsa.pub
echo "http://localhost:8624/apk/alpine-test/" >> /etc/apk/repositories
/ # apk add php-zts85-cli
WARNING: opening from cache http://localhost:8624/apk/alpine-test/x86_64/APKINDEX.tar.gz: v2 database format error
ERROR: unable to select packages:
  php-zts85-cli (no such package):
    required by: world[php-zts85-cli]

This shows the aforementioned v2 database format error.

Switching to alpine 3.19 instead we get this:

[m@M m]$ docker run -it --network host alpine:3.19 sh

wget -O "/etc/apk/keys/alpine-test@proget.rsa.pub" http://localhost:8624/apk/alpine-test/keys/alpine-test%40proget.rsa.pub

as you can see, the apkindex does exist and advertises the different packages, but apk doesn't see them and I can't install them.

When I use my own repository (not public atm) or a cloudsmith testing repository, everything works as expected:

[m@M m]$ docker run -it --network host alpine:latest sh
/ # apk add curl sudo bash wget nano
/ # curl -1sLf 'https://dl.cloudsmith.io/public/static-php/alpine-test/setup.alpine.sh' | sudo codename=any-version -E b
ash

Hi @henderkes,

Thank you for sending all this over! We are going to dig into this a bit further and will let you know what we find.

Thanks,
Rich

Hi @henderkes,

Can you provide where you are getting your test packages from? I have a feeling it has to do with them more than the index. I setup the environment you specified with alpine packages I pulled from Zend PHP and had no issues. I was able to update the index and install multiple packages.

Thanks,
Rich

henderkes

Hi, you can get the packages from the codesmith repo I set up. They're still available there.

I've also tried with two test packages containing just hello.txt and world.txt and got the same results.

Running inedo with Docker, if it matters!

Hi @henderkes,

I did try to download that script to extract the repo you were referring to, but Alpine does not have bash installed, only ash, so I get an error when attempting to run it. Could you please provide me a direct link? To be honest, this all screams a configuration error on Alpine or an issue with the APK directly.

In my test, I created a feed in ProGet with a connector created pointing to "https://repos.zend.com/zendphp/apk_alpine320/x86_64/". I then added my feed to alpine, apk update, and then apk add php85zend. Everything worked as expected.

Thanks,
Rich

@rhessinger You can install bash on alpine too. You can get a direct download to the packages here: https://pkg.henderkes.com/85/php-zts/packages?q=&type=alpine

For testing it should be enough to download php-zts-cli and php-zts-zstd.

If connected feeds are working for you, the issue may be specific to local feeds.

Hi @henderkes,

Thanks for sending those packages over. I was able to recreate some issues with those packages and we are currently still looking for the cause. I'll send over an update once I have a bit more information.

Thanks,
Rich
