Bump Monero to v0.18.5.3

[sethforprivacy]

Adds Monero/0.18.5.3, bumping the Monero image to v0.18.5.3.

Architectures: linux/amd64, linux/arm64 and linux/arm/v7, the same as 0.18.5.1. Compared with Monero/0.18.5.1, the Dockerfile changes only MONERO_VERSION and the three FILE_CHECKSUMs. In scripts/, the only change is that notifier.sh now quotes its argument expansion (curl "$@").

Provenance: the checksums come from hashes.txt. That file carries a good signature from binaryFate (81AC 591F E9C4 B65C 5806 AFC3 F0AF 4D46 2A0B DF92, as listed in utils/gpg_keys/binaryfate.asc in monero-project/monero). I also downloaded all three tarballs from downloads.getmonero.org and checked them against those hashes.

Local validation:

• Built the linux/amd64 image. It reports v0.18.5.3-release.
• Swapped it into both btcpayserver_monerod and btcpayserver_monero_wallet on a btcpayserver-docker mainnet test instance (BTCPay 2.4.4, Monero plugin 1.3.5).
• monerod resynced to tip with peers, block-notify callbacks returned 200, and after a BTCPay restart the plugin reopened the existing wallet, with the wallet height matching the daemon's and XMR reported available.

📝 Walkthrough

Walkthrough

The change adds a Monero 0.18.5.3 multi-stage image for amd64, arm64, and arm/v7. It verifies downloaded binaries, configures a non-root runtime user and data directories, and adds startup and notifier scripts.

Changes

Monero 0.18.5.3 Image

Layer / File(s)	Summary
Build and configure the image Monero/0.18.5.3/Dockerfile	The builder selects binaries and checksums for amd64, arm64, or arm/v7, verifies the downloaded archive, and extracts the CLI, wallet RPC, and daemon. The runtime installs gosu and curl, creates the configurable monero user and group, sets up data and wallet paths, exposes ports 18080–18082, and sets the entrypoint.
Initialize the container and forward notifier arguments Monero/0.18.5.3/scripts/docker-entrypoint.sh, Monero/0.18.5.3/scripts/notifier.sh	The entrypoint updates directory ownership and the .bitmonero symlink, then runs the supplied command as monero. The notifier passes its arguments to curl.

Merge Risk: 🔵 Low · up to e9b5b

Callbacks requiring a header or other argument containing spaces may fail. Quoting the notifier arguments is a small fix; otherwise the image is mergeable with this limitation understood.

_{A rabbit checks the checksum trail,
Then hops where Monero binaries sail.
The data link is set in place,
Gosu starts the command with grace.
Curl gets each argument on its way,
And bun rests after build day.}
