Failed to create the directory $PKGDEST inside aurcache-builder

[xXPerditorXx]

My compose.yml for podman in Host-Build-Mode:

services:
    aurcache:
        image: ghcr.io/lukas-heiligenbrunner/aurcache:latest
        ports:
        - "8080:8080" # Frontend
        - "8081:8081" # Repository
        volumes:
          - ./aurcache/db:/app/db
          - ./aurcache/repo:/app/repo
          - /run/user/1000/podman/podman.sock:/var/run/docker.sock
          - ./aurcache/builds:/app/builds # artifact_cache
          #- ./aurcache/builds/config/pacman_x86_64/mirrorlist:/app/config/pacman_x86_64:Z
        environment:
          - BUILD_ARTIFACT_DIR=/home/arch/Downloads/AURCacheOwn/aurcache/builds # also absolute path is possible
            ## HERE
          #- MIRROR_RANK_SCHEDULE=0 0 2 * * 0
            ## END HERE
        privileged: true
        restart: unless-stopped

volumes:
  artifact_cache:
        name: artifact_cache
        driver: local

I now got the problem, that which ever AUR package I throw at it, it always tells me:

(1/4) Reloading system manager configuration...

Here I tried with debtap, but it does it downgrade too.
Also tried :git tag too

Update

I changed BUILD_ARTIFACT_DIR, aswell as the builds path to a longer version.

services:
    aurcache:
        image: ghcr.io/lukas-heiligenbrunner/aurcache:git
        ports:
        - "8080:8080" # Frontend
        - "8081:8081" # Repository
        volumes:
          - ./aurcache/db:/app/db
          - ./aurcache/repo:/app/repo
          - /run/user/1000/podman/podman.sock:/var/run/docker.sock
          - /home/arch/Downloads/AURCacheOwn/aurcache/builds:/app/builds:Z # artifact_cache
          #- ./aurcache/builds/config/pacman_x86_64/mirrorlist:/app/config/pacman_x86_64:Z
        environment:
          - BUILD_ARTIFACT_DIR=/home/arch/Downloads/AURCacheOwn/aurcache/builds # also absolute path is possible
            ## HERE
          #- MIRROR_RANK_SCHEDULE=0 0 2 * * 0
            ## END HERE
        restart: unless-stopped

volumes:
  artifact_cache:
        name: artifact_cache
        driver: local

Now it gives me:

Hey, thanks for the good catch!
I think a refactoring sometime ago messed up the cache path creation.
#300 should fix this. I could only reproduce your second comment, but this should fix the first one too.
Maybe can you test this out by trying the :pr-300 docker tag and give me feedback if it works as expected?

[xXPerditorXx]

Oh good, thought it was a problem on my end.
I changed :git to :pr-300, to get:

failed to build packageDocker container wait error: 

I also tried the compose with the mirrorlist setting set above not commented.

[xXPerditorXx]

Oh wait, my :git has the same problem now, I'll try fixing that

[xXPerditorXx]

So I deleted my mirrorlist file and recopied it into the pacman dir. Somehow it didn't auto download it.
Reproducing the error is kinda strange, because now I have the old error again, but I haven't changed my compose.yml

==> ERROR: Failed to create the directory $PKGDEST (/var/cache/makepkg/pkg/downgrade).

error: failed to download sources for 'downgrade-11.5.5-1':

[xXPerditorXx]

So, it fixed it now. I made chmod 755 -R aurcache and the problem was fixed.
So it seems to me your :pr-300 did it for me.

Thank you for your work!

[Lukas-Heiligenbrunner]

Great this works now!
Do you think the permission problem was only on your side or should there anything be changed here to make that easier?
For me such permission errors are always strange and somehow it works then^^

[xXPerditorXx]

I think it's worth a note on the docs page. I wasn't entirely sure, because I'm new to containers in general and just started learning it because of this project.

But I think it makes sense depending on where you tested this container, that because of persistent storage needs, you need some kind of permissions set on you host file system.

So yeah, I think it's worth a mention in the docs.
In my case I used podman
