Fetch Alpine static apk-tools from dl-cdn in CI - #266
Merged
Merged
Conversation
jirutka/setup-alpine downloads apk.static from gitlab.alpinelinux.org before it installs anything. That host has been timing out, which fails all six Alpine jobs in the setup step. Download the apk-tools-static package from dl-cdn.alpinelinux.org, which the action already uses for packages, and serve sbin/apk.static to the action from localhost, since its apk-tools-url input only accepts http(s) URLs. The package URL and the binary's SHA-256 are pinned, and the action still verifies the hash before using it.

Two small suggestions on the apk.static fetch step.
Plain --retry skips refused or reset connections, and curl has no connect or transfer timeout by default, so a dl-cdn hiccup could fail the step or stall it until the job timeout.

The six Alpine jobs fail in the
Setup Alpine Linuxstep before anything is built.jirutka/setup-alpine@v1downloads the staticapk.staticbinary fromgitlab.alpinelinux.org, and that host times out (curl error 28 after 10 s). This hit master on 2026-10-22 and #265 on 2026-10-28, and it fails every PR while the host is down.dl-cdn.alpinelinux.org, where the action already gets its packages, stays reachable.A new step downloads the
apk-tools-staticpackage from dl-cdn, extractssbin/apk.staticand serves it on127.0.0.1:8099. The action gets that URL through itsapk-tools-urlinput, which only acceptshttp://andhttps://URLs (notfile://), and checks the file against the pinned SHA-256 before using it. The binary is the only thing the action fetches from gitlab: QEMU and the Alpine packages already come from dl-cdn. The build and test steps are unchanged.The package is pinned to
v3.22/main/x86_64/apk-tools-static-2.14.12-r0.apk. The action deliberately stays on apk-tools 2.14.x (its default is 2.14.10), whilelatest-stablenow ships 3.0.8. x86_64 is the runner's arch; the static apk installs the target arch into the chroot as before. dl-cdn removes an old package file when Alpine updates it, so if the URL starts to 404 the URL and hash need updating, as the comment in the workflow says.Testing:
Downloading http://127.0.0.1:8099/apk.staticandapk: OK, has no gitlab requests, andmake testpasses (75 pass, 0 fail).make testpasses.
