Problem

The example repository build-docker-in-runpod failed to build with current Bazel versions.

Bazel 9.0.0 incompatibility

Now Bazelisk downloads 9.0.0 by default which has commands and dependencies incompatible with the example. It rises:

ERROR: No repository visible as '@rules_oci' from main repository

Outdated rules_oci version

The ./WORKSPACE file uses rules_oci-2.0.0-alpha2, which is a outdated one

What to do to fix it

1. Add a .bazelversion file to the example specifying a compatible version (I used 6.4.0 and it worked)

2. update rules_oci to a stable release (e.g., v2.0.1) with correct sha256
