Some checks failed
cc-ci/testme cc-ci: failure
Minor bump — no operator action required (Postgres/ClickHouse changes are automatic). - Postgres: use pgautoupgrade/pgautoupgrade:18-alpine in place of the custom pg_upgrade entrypoint. The existing cluster is upgraded in place automatically on deploy; PGDATA pinned to the legacy path; adds a pg_isready healthcheck. Removes entrypoint.postgres.sh.tmpl and DB_ENTRYPOINT_VERSION. - ClickHouse backup fetch: cache the clickhouse-backup binary on the persistent volume and retry with backoff to avoid the download crash-loop. The tool is required — if it can't be installed after retries the entrypoint aborts and the server does not start, rather than coming up without backup/restore. - Add CLICKHOUSE_DATABASE_URL; bump the clickhouse entrypoint config version. - Remove a stray broken link reference in the README.

# clickhouse-backup is a backup tool (backupbot pre/post-hooks: `clickhouse-backup create/restore`).
|
|
# It is a 22 MB GitHub download (rate-limit / network), which can fail to download, and lead to crash loop and download throttling.
|
|
#
|
|
# to make the download smoother:
|
|
# - cache the binary on the persistent clickhouse data volume (/var/lib/clickhouse) so it is fetched
|
|
# at most once and reused on every container restart (no re-download amplification);
|
|
# - retry with backoff to ride out transient GitHub failures
