Summary of ChangesHello, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request significantly enhances the Dokploy template ecosystem by introducing a feature-rich, production-ready template for Technitium DNS Server. It provides flexible deployment options, from simple home setups to highly available clustered and cloud-based configurations, leveraging Cloudflare services for security, backup, and remote access. Concurrently, it establishes a sophisticated memory management framework for Claude, enabling it to systematically learn from project history and apply best practices, which is reflected in the updated CLAUDE.md and the newly added MEMORY.md and related skill documentation.

Code Review
This pull request introduces a comprehensive and well-documented Technitium DNS Server template with multiple presets, featuring a well-thought-out architecture including native clustering and Cloudflare integrations. However, critical security and configuration issues were identified in the docker-compose.yml file. Specifically, the administrative interface is insecurely exposed over unencrypted HTTP, and there are potential command injection vulnerabilities in the backup sidecar's entrypoint script. Furthermore, the rclone-backup service configuration relies on a hardcoded path to a missing rclone.conf file, impacting portability and leading to flawed health check logic. Addressing these issues is crucial for enhancing the template's security, reliability, and portability.

The health check for the rclone-backup service is unreliable. It checks for the word "successfully" in the last line of today's log file. This means the service will be reported as unhealthy for the entire period between backups (e.g., for ~24 hours on a daily schedule). It will also fail if the log message is ever changed.
A more robust health check could be implemented. For example, the entrypoint script could touch /tmp/backup_successful after a successful run, and the health check could verify the timestamp of this file to ensure it's recent.

The Technitium admin console port (5380) is directly exposed on the host's network interface, allowing unencrypted (HTTP) access and bypassing the TLS encryption provided by Traefik. This creates a security risk where administrative credentials could be intercepted, especially if the host's firewall is misconfigured. It is recommended to remove the 5380:5380/tcp port mapping and rely exclusively on Traefik for secure, TLS-encrypted access to the admin console.

The rclone-backup service is configured with a hardcoded host path /opt/dokploy/blueprints/technitium-dns/rclone.conf for rclone.conf. This makes the template non-portable and brittle, as it depends on a specific directory structure on the host. Furthermore, the rclone.conf file is missing from the repository, which will cause the backup service to fail upon deployment. It is strongly recommended to configure rclone using environment variables (e.g., RCLONE_CONFIG_R2_...) to eliminate the dependency on a physical configuration file and significantly improve portability and reliability.

The rclone-backup service's entrypoint uses a shell script that directly interpolates environment variables such as R2_BUCKET_NAME and BACKUP_INTERVAL. If these variables are configured with malicious values (e.g., containing semicolons or backticks), it could lead to arbitrary command execution within the container. It is recommended to use environment variables that rclone supports natively for configuration (e.g., RCLONE_CONFIG_R2_TYPE, RCLONE_S3_BUCKET) and ensure all variables are properly quoted and validated if a shell script is necessary.

The variables dns_server_domain and node_role are defined in the global [variables] section but are not used by the docker-compose.yml file from this section. dns_server_domain is not used at all, and node_role is defined within each preset. To avoid confusion and keep the template clean, these unused global variables should be removed.

restart: always conflicts with the blueprint standards for blueprints/**, which require restart: unless-stopped on all services (see .github/instructions/blueprints.instructions.md). Please switch both services to unless-stopped for consistency and predictable operator behavior.

This compose file publishes ports 53 and 5380 to the host. That violates the project blueprint rules (“Never expose ports; Traefik handles routing” in .github/instructions/blueprints.instructions.md) and also undermines the PR claim of “HTTPS-only exposure” because 5380 becomes reachable directly. Please remove host port publishing (at least for 5380) and follow the repo’s preferred routing pattern.

The rclone-backup service uses a bind mount to /opt/dokploy/blueprints/technitium-dns/rclone.conf, but this PR doesn’t add that file anywhere in the blueprint directory. This will fail at deploy time and also violates the “named volumes only, no bind mounts” blueprint rules. Consider generating the rclone config via template.toml [[config.mounts]] content (or env-based rclone config) instead of relying on a host path.

PRIMARY_NODE_IP is referenced in the clustered-secondary preset (${primary_node_ip:?…}) but primary_node_ip is not declared in [variables]. This will fail template validation / preset rendering. Please add primary_node_ip to the [variables] section (and keep naming consistent with other Cloudflare-style variables).

The template uses r2_account_id as the source for the CF_ACCOUNT_ID environment variable. Given repo conventions for Cloudflare integration (e.g. .github/instructions/blueprints.instructions.md and other templates), this should likely be a cf_account_id variable (or directly reference ${CF_ACCOUNT_ID}) to avoid confusion and keep Cloudflare variables consistently named/prefixed.

Defining networks (technitium-net, dokploy-network) conflicts with the blueprint rules (“Networks: Don't define (Dokploy manages networking)” in .github/instructions/blueprints.instructions.md). Please remove the networks: section and any service-level network attachments unless there’s a documented, template-standard exception.
| profiles: | ||
| - backup |
There was a problem hiding this comment.
rclone-backup is gated behind a Compose profiles entry. That means setting R2_BACKUP_ENABLED=true is not sufficient to run backups unless the backup profile is explicitly enabled at deploy time. Either remove the profile gating (and rely on the env toggle) or document/profile-enable it from Dokploy so the template behaves as described.

|

The README states that “Technitium data is synced to R2 daily/hourly” by this template, but rclone-backup is currently behind the Compose backup profile and may not run by default. Please either (a) update the README to clearly state that the backup profile must be enabled in Dokploy / deployment, or (b) adjust the compose so backups actually run when R2_BACKUP_ENABLED=true without requiring extra profile configuration.

The PR title/description focuses on adding the Technitium DNS blueprint, but this PR also adds/updates multiple repo-level agent/memory files (MEMORY.md, CLAUDE.md, .claude/skills/claude-mem-mastery/*) that aren’t mentioned in the summary.

4. template.toml missing config.env 📘 Rule violation ✓ Correctness
The template defines variables and presets but does not provide a [config.env] mapping section to centralize environment variable injection. This violates the requirement to declare variables under [variables] and map them via [config.env].
Agent Prompt
## Issue description
The template lacks a `[config.env]` section for mapping variables into container environment variables.
## Issue Context
The compliance requirement mandates centralized declaration in `[variables]` and mapping through `[config.env]` for auditable configuration.

11. Tunnel feature not implemented 🐞 Bug ✓ Correctness
The template and README describe Cloudflare Tunnel remote admin access, but the compose file contains no cloudflared service (only unused CLOUDFLARE_TUNNEL_ENABLED / CF_TUNNEL_TOKEN env vars), so Tunnel functionality cannot work as documented.
Agent Prompt
### Issue description
Tunnel is documented but not implemented in compose (no cloudflared service), so users cannot achieve the advertised remote admin access.
### Issue Context
Other blueprints implement Cloudflare Tunnel via an explicit `cloudflared` service.
