Obtain and verify install tarball

Obtain the official Alpine Linux image

Choose tarball to download based on the model of Pi you have

• Partial table of model of Raspberry Pi to Linux kernel max architecture available (where aarch64 > armv7 > armhf). armhf should be a ‘safe’ choice for all models, but aarch64 is preferred when possible, then armv7, then armhf.

You should obtain the appropriate tarball as well as sha256 and GnuPG signatures for that tarball, based on the arch available, which depends on your model (above).

• NOTE: For up-to-date links/version you should use the official download page, Raspberry Pi table.

Verify the tarball has the expected contents

See ‘verify downloaded installation media’.
