feat(self-host): docker compose stack for self-hosted deployments#6046TechHutTV wants to merge 3 commits into
Conversation
Adds self-host/, a single-box deployment that runs Macro on an operator's own domain with `docker compose` and no Rust, Nix or Node toolchain. Caddy terminates TLS and serves the app and every API from one origin, with object storage and FusionAuth on their own hostnames: presigned URLs are signed for the storage host, and FusionAuth builds absolute URLs from the host it is reached on, so neither can share the app's path space. macroctl generates per-deployment secrets, renders the FusionAuth kickstart, provisions storage, queues, tables and search indices, and covers backup, restore and upgrade. Service images run the .#local-stack-binaries aggregate, so a self-hosted install and a developer's local stack execute identical artifacts. The compose file, Caddyfile and .env.example are checked in so no toolchain is needed to deploy; scripts/check-drift.py reads inventory.rs, resources.rs and macro_queues and fails if they fall behind, and CI runs it before publishing any image. Supporting changes, each required for a deployment on a real domain: - macro_aws_config: S3_ENDPOINT_URL overrides the S3 endpoint alone, so presigned URLs are signed for the public storage host rather than being rewritten to localhost. - authentication_service, invite_email: APP_BASE_URL names the deployment's own origin. Post-login redirects and invite links were hardcoded to localhost. - servers.ts: logout returns to the app's own origin. The fixed localhost:3000 stranded the user on a dead page under any proxy origin, including the headless local stack and tunnels. - macro_db_migrator: a feature-gated macro_db_migrate binary, so the init container applies migrations without sqlx-cli or a source checkout.

📝 WalkthroughSummary by CodeRabbit
WalkthroughAdds a complete self-hosted Macro deployment with Docker Compose, Caddy routing, environment generation, provisioning scripts, FusionAuth bootstrap, resource manifests, operational commands, and drift validation. Adds Dockerfiles and a GitHub Actions workflow that builds and publishes service, frontend, initialization, and worker images. Updates application URL handling and S3 endpoint behavior for self-hosted deployments. Merge Risk: 🟠 High · up to This PR adds a new self-hosted deployment and image-publishing path, but the current head can execute unvalidated release input, publish altered images, fail during identity bootstrap, silently generate incorrect secrets or mail settings, and continue upgrades without a complete key-bearing backup; services also default to root, with an optional host-control socket mount.

Derive SMTP_SECURITY from SMTP_PORT before applying the TLS fallback.
When SMTP_SECURITY is unset and SMTP_PORT=25, line 35 assigns TLS. The port-25 branch then preserves that value, so the generated kickstart receives TLS instead of NONE. A plaintext SMTP endpoint may reject mail with this setting.

The admin registration targets a hardcoded application id that this deployment never creates.
Line 94 creates the application at /api/application/@@FUSIONAUTH_CLIENT_ID@@, and macroctl generate-secrets sets FUSIONAUTH_CLIENT_ID to a freshly generated UUID. The registration on line 143 uses the fixed id 3c219e58-ed0e-4b18-ad48-f4f92793ae32, which appears to be the local development constant. The ids never match, so the registration request references a non-existent application and the kickstart fails.
Use the placeholder instead.

docker compose --env-file variable interpolation dollar sign escaping values in env file
💡 Result:
In Docker Compose, the method for handling literal dollar signs depends on whether the value is defined directly within the compose.yaml file or inside an external environment file (.env). Escaping in compose.yaml When you need a literal dollar sign in a value defined directly inside your compose.yaml file (such as in an environment or command block), you must use a double dollar sign ($$) [1][2][3]. This tells Docker Compose to treat it as a literal character rather than attempting to interpolate it as a variable [1][2][4]. For example: environment: - PASSWORD=p$$ssword # Renders as p$ssword Escaping in.env Files When using an.env file—whether it is the default.env file at the project root or one passed via --env-file—the syntax rules differ because these files support specific quoting behaviors [5][6]. To include a literal dollar sign in an.env file, wrap the value in single quotes [7][6]. Single-quoted values are treated literally by the Docker Compose interpolation engine, meaning any dollar signs within them will not be expanded [5][6]. For example, in your.env file: APIKEY_SALT='$foo$bar' # Renders as $foo$bar Summary of Differences 1. compose.yaml: Use $$ to escape the dollar sign [1][2]. 2..env file: Use single quotes ('...') around the value to preserve the dollar sign literally [5][6]. Double-quoted (") values in.env files are still subject to interpolation [5][6]. Note: If you use an external tool (like python-dotenv) to read the same.env file outside of Docker Compose, be aware that some external parsers may not recognize Docker's specific quoting or escaping conventions, potentially leading to compatibility issues [8].

The default admin email is invalid for an apex domain.
${domain#*.} removes the first label. For macro.acme.io the result is acme.io, which is the intent. For an apex domain such as acme.io, the result is io, so the default becomes admin@io. FusionAuth rejects that address, and the kickstart admin registration fails.
Derive the mail domain only when the input has three or more labels, or default to the full domain.

The blanket REPLACE_ME substitution assigns the Postgres password to any unmapped key.
This gsub runs for every key that is not in v. Any .env.example entry that still holds REPLACE_ME receives POSTGRES_PASSWORD. The value looks filled, so the guard on line 160 reports success and the deployment starts with the wrong secret in place. A new placeholder added to .env.example later fails the same way, silently.
Restrict the substitution to the keys that embed the database password, and let every other REPLACE_ME reach the guard.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
A parse miss makes the drift gate pass silently.
The block regex depends on the exact indentation and the trailing comma in inventory.rs. If rustfmt or an edit changes that shape, re.findall returns no blocks, wanted becomes empty, every service check is skipped, and the script exits 0 with 0 services. The CI drift gate then reports success while the artifacts are unchecked.
Assert that the parse produced a plausible result before running the comparisons.
🛡️ Proposed fix
wanted = [s for s in services if "Mode::Local" in s["modes"] and s["compose_name"] != "gmail_forwarder"]
+
+# A parse miss must not look like "no drift". inventory.rs always declares
+# several local-mode services, so an empty result means the regex went stale.

+ print(
+ "check-drift.py parsed 0 local-mode services from inventory.rs — "
+ "the RustService block pattern is stale; fix the parser before trusting this gate.",

Hey @TechHutTV, thanks for putting up a pr. I'll take a closer look at it in the morning. An immediate concern of mine is having users run the sync-service using We are considering moving off of cloudflare durable objects entirely and onto our own solution. Until then it might be interesting to see if celld might work as a self-hostable replacement since they claim it is wrangler.toml compatible. Though this is not something I have tested myself. |

Description
The README says Macro is fully open source, not open core, and the FAQ says you can self-host under the AGPL. You can, it's just very difficult and not user friendly. RUNNING_LOCALLY.md documents a dev stack rather than a deployment, the infra folder is 41 Pulumi stacks written against Macro's own AWS account, every secret comes from Doppler or a stub compiled into a Rust binary, and the app resolves its own hostnames from an Environment enum with three values, none of which can be a self-hosted domain. Nothing is published either, so no images, no upgrade path, no backup story.
This adds
self-host/, a docker compose deployment you run on your own domain with no Rust, Nix, or Node toolchain. Caddy terminates TLS and serves the app and every API from one origin, which works because the headless bundle already builds withVITE_LOCAL_BACKEND_ORIGIN=same-originand calls its APIs relative to wherever it's served. Object storage and FusionAuth get their own hostnames, since presigned URLs are signed for the host they get fetched from and FusionAuth builds absolute URLs from whatever host it's reached on.macroctlis the only thing you actually run and it covers secrets, provisioning, backup, restore and upgrade.Service images come from the existing
.#local-stack-binariesaggregate, so a self-hosted install runs identical binaries to a developer's local stack. The compose file, Caddyfile and.env.exampleare checked in so nobody needs a toolchain to deploy, andscripts/check-drift.pyreads the same Rust catalogs the dev stack is built from and fails in CI if they fall behind. Scope is deliberately one box, no HA and no Kubernetes.Changes

Every one of these is required for a deployment that isn't Macro's own.
crates/macro_aws_config/src/lib.rsS3_ENDPOINT_URLoverrides the endpoint for S3 only, leaving SQS, DynamoDB and KMS alone, and skips the localhost URL rewriting when object URLs are already public. Without this every presigned URL gets rewritten to localhost and no upload or download works off the dev machineservices/authentication_service/src/api/utils.rsdefault_redirect_url()honorsAPP_BASE_URL.

I verified a good chunk of this by actually running it.
macroctl generate-secretsend to end, then machine checked the resulting.envfor the shared identity groups the services require, database URL and password consistency, valid v4 UUIDs, a 32 byte MCP key and complete domain substitution. The kickstart renderer went through the same treatment against that real.env, including JSON escaping of secrets containing quotes and backslashes, both SMTP security modes, and the identity provider append path. On top of that, every Caddy upstream resolves to a real compose service or alias, all compose volumes, networks and depends_on resolve, the frontend route parity invariant thatproxy/test.rsenforces still holds, and the drift check both passes and, when I deliberately broke it, fails.Do note what I have not done. I haven't built the images or brought the stack up on a real host, and the Rust and TypeScript edits haven't been compiled. So
cargo checkon the four touched crates and one realmacroctl upagainst a test domain are the obvious next steps. Happy to do both if you want this to go further.Known limitations
Object storage is LocalStack, covering S3, SQS, DynamoDB and KMS, with persistence on and its volume included in the backup. It works, and it's what the dev stack has run for years, but it's a development tool and it's the first thing I'd replace with managed equivalents. The README says so directly. Worth calling out that the KMS key encrypts users' stored Cursor API keys, so if you lose that volume without a backup those rows can never be decrypted again.
Document sync state is a working set rather than the record. sync-service runs under workerd with Durable Object storage on a named volume, and snapshots get published back to document-storage-service, so the durable copy lives in Postgres and S3. Edits that haven't flushed yet only live in that volume though.
There's no HA here, it's one box with one of everything. The agent harness sits behind a compose profile and is off by default because it mounts the host Docker socket to create sandbox containers, which is root equivalent access to the machine. The PDF service and scheduled actions have no container here or in the local dev stack, so they're absent rather than broken. And some things stay hosted no matter what, like the iOS app, push notifications through SNS, and Google's and Apple's approvals, which are Macro's and not an operator's.
Note
High Risk
Introduces a full public deployment surface (auth, TLS routing, image publish pipeline) with explicit guards around the auth binary, but mistakes in secrets, presigned URL hosts, or SSO redirect policy would be security- or availability-critical.
Overview
Adds
self-host/, a single-box Docker Compose deployment operators run withmacroctl(generate-secrets, up/down, backup/restore, upgrade). Caddy terminates TLS and serves the SPA plus path-routed APIs from one origin; separate hostnames cover FusionAuth and public S3 presigning. Checked-indocker-compose.yml,Caddyfile, and.env.examplepair withinit/provisioning (migrations via newmacro_db_migratebinary, LocalStack buckets/queues/tables/KMS, OpenSearch indices, FusionAuth kickstart) andscripts/check-drift.py(plusjust self-host-checkand CI) so artifacts stay aligned with the local inventory catalogs..github/workflows/self-host-images.ymlbuilds and pushesmacro-services,macro-web,macro-init, and worker images to GHCR on version tags; the services job swaps in the productionauthentication_service(not the devreturn_passwordless_codebuild) and verifies that swap.Core app changes enable arbitrary operator domains:
APP_BASE_URL/S3_ENDPOINT_URLin auth redirects, SSOoriginal_urlallowlisting, invite links, and S3 client URL handling (path-style + no localhost rewriting when URLs are already public). The web client sends logout to/app/loginon the proxy origin instead of a fixed localhost port.Reviewed by Cursor Bugbot for commit 490a379. Bugbot is set up for automated code reviews on this repo.
