InfluxDB 3 Core, Proven By A Write And An SQL Query
InfluxDB 3 Core on EL 10 from the vendor's release (checksum-verified), as a hardened systemd service on loopback with file object storage; the binary runs from its release directory (it links the Python it ships); the live test writes a point in line protocol and reads it back with SQL. Original role, live-tested on Rocky Linux 10.

Documentation
influxdb3
InfluxDB 3 Core, the time series database, from the vendor's release (sha256-verified against the .sha256 published beside it), as a hardened system service on loopback with file object storage under its own data directory. Original role for EL 10, live-tested with podman on Rocky Linux 10.
No package, so the checksum is the whole story. EL 10 carries no
influxdb3; InfluxData ships a release with a checksum file beside it. The
role downloads both and has Ansible's get_url refuse the asset unless its
SHA-256 is the one in the vendor's file, then installs the binaries as
root's in /usr/local/bin, pinned by influxdb3_version.
A service account, a hardened unit, a loopback listener. influxdb3
is a system user with no shell that owns the data directory and nothing
else; the unit runs with NoNewPrivileges, PrivateTmp, ProtectHome and
ProtectSystem=strict. The listener is 127.0.0.1:8181 by default,
for a proxy that authenticates or a client on the same host; the live test
reads the listening sockets and expects loopback only.
Proven by a write and a query. The live test writes one point in
line protocol to /api/v3/write_lp and reads it back with SQL through
/api/v3/query_sql, expecting the row with its tag and field - ingest,
the write-ahead log, the parquet-backed store and the query engine all
ran. Telemetry upload is off.
Tokens are off on loopback, by choice. --without-auth is the default
because the listener is loopback and a proxy in front authenticates; set
influxdb3_without_auth: false and mint tokens with influxdb3 create token --admin for a listener clients reach directly. Core is the free
edition (a 72-hour query window on unlimited data); Enterprise is another
binary.
The binary stays in its release directory. influxdb3 links against
the Python it ships (libpython3.13 under python/lib, found relative to
the binary) for the processing engine; copied out on its own it cannot
load. The role keeps the unpacked release under /usr/local/src and links
/usr/local/bin/influxdb3 to it, which the hardened unit runs read-only.

ansible-clickhouse
ClickHouse on EL 10 from the upstream LTS release (sha512-verified), as a hardened systemd service on loopback with the default user behind a password; the live test creates a MergeTree table, inserts a row and selects it back over HTTP; a query without credentials is refused. Original role, live-tested on Rocky Linux 10.
ansible-dragonfly
Dragonfly on EL 10 from the vendor's release, pinned by a SHA-256 the role carries (the vendor publishes no checksum file), as a hardened systemd service on loopback behind a password kept in a flagfile; the live test speaks RESP itself: an unauthenticated PING and a wrong password are refused, AUTH + SET + GET round-trip. Original role, live-tested on Rocky Linux 10.
ansible-mariadb-server
MariaDB bound to loopback (the package listens everywhere), with the mariadb-secure-installation steps applied by the role: anonymous users, the test database and remote root gone, LOAD DATA LOCAL off, reverse DNS off. Provisions an application database and a user that can see nothing else. Original role, live-tested on Rocky Linux 10.
ansible-meilisearch
Meilisearch on EL 10 from the vendor's release, pinned by a SHA-256 the role carries (the vendor publishes no checksum file), as a hardened systemd service on loopback in production mode behind a master key; the live test creates an index and documents, waits for the indexing task, searches and finds the one match, and sees a keyless request refused. Original role, live-tested on Rocky Linux 10.
ansible-pocketbase
PocketBase, the backend in one binary, from the upstream release (sha256-verified), a hardened system service on loopback, its data under one directory. The live test creates a superuser with PocketBase's own command, sees a wrong password refused, makes a collection and a record, reads it back, sees an anonymous read refused, deletes the collection. Original role, live-tested on Rocky Linux 10.
ansible-postgresql
PostgreSQL server with guarded initdb, SCRAM-SHA-256 auth, managed conf.d drop-in, templated pg_hba, and app database + owner provisioning. Original, live-tested (Molecule/podman) role.
