The Alpine sqlite3 binary dynamically links against libreadline.so.8; without it the agent crashes at the validate stage of the pipeline with 'Error loading shared library libreadline.so.8: No such file or directory'. Add the readline package to the runtime stage so sqlite3 starts cleanly.

# Backupy agent image — multi-stage, multi-arch (linux/amd64, linux/arm64).
|
|
# Bundles client binaries the agent shells out to during dump:
|
|
# pg_dump, mysqldump, mongodump, redis-cli, sqlite3.
|
|
#
|
|
# Built from the REPO ROOT so the protobuf generated code in
|
|
# packages/proto/gen/go/backupv1 is in build context (referenced by the
|
|
# `replace` directive in apps/agent/go.mod).
|
|
#
|
|
# Example local build (multi-arch):
|
|
# docker buildx build \
|
|
# --platform linux/amd64,linux/arm64 \
|
|
# --build-arg VERSION=$(git describe --tags --always) \
|

# --build-arg COMMIT=$(git rev-parse --short HEAD) \
