Bluesky Personal Data Server

[ekevu123]

@sfeldkamp It works, I could set the app up. But I didn't migrate my data, because apparently, you can't go back to cloud later, and I wasn't sure if I wanted to maintain this at the moment.

I can share a tutorial, but you came first, and I don't want to spoil the fun for you, so feel free to try first

@ekevu123

Please share! I'll take whatever help you can offer. Or post a submission if you have it done already and I can test it out.

According to the docs Cloudron will take over maintenance of the app image after it's published.

And Bluesky recently implemented incoming account migration so now a user can go back to Bluesky hosted PDS.

They will …. But better to be prepared to maintain until they adopt it. Sometimes it’s quick, sometimes not.

[ekevu123]

Okay, find below information about how the app runs. What I haven't tested:

• Setting up notification e-mails (should be simple using SMTP)
• Actually transferring the data (a test account could be set up)
• Handling the integrated update mechanism: so far, all updates would need to be done manually.

The Core Concept

Standard deployment (Bluesky PDS original):

• Docker Compose file with 3 separate containers:
  • pds - The main application
  • caddy - Reverse proxy and TLS termination
  • watchtower - Automatic container updates

Cloudron deployment:

• Only 1 container - The main application (pds)
• Cloudron provides everything else:
  • Reverse proxy (TLS, HTTPS)
  • Health monitoring
  • Storage management
  • Update mechanism

Remove from the application:

• Caddy service - Cloudron's reverse proxy handles HTTPS/TLS
• Watchtower service - Cloudron's update system handles updates
• Docker Compose file - Cloudron doesn't use compose; it builds from Dockerfile

Keep from the application:

• The main app (Node.js + PDS in this case)
• The Dockerfile (but modify it to use a startup script)
• All application code and logic

Files You Need to Create

Three new files are required:

1. startup.sh - Environment validation and initialization

2. CloudronManifest.json - Cloudron deployment configuration

3. Modifications to Dockerfile - Add startup script and health check

#!/bin/bash
set -e

# Startup script for Bluesky PDS on Cloudron
# This script validates required environment variables and initializes the application

# Required environment variables
REQUIRED_VARS=(
  "PDS_HOSTNAME"
  "PDS_JWT_SECRET"
  "PDS_ADMIN_PASSWORD"
  "PDS_PLC_ROTATION_KEY_K256_PRIVATE_KEY_HEX"
)

# Check required variables
echo "Validating environment variables..."
for var in "${REQUIRED_VARS[@]}"; do
  if [[ -z "${!var:-}" ]]; then
    echo "ERROR: Required environment variable $var is not set"
    exit 1
  fi
done

Make sure to change all hardcoded references for the data directory /pds to /app/data!

Then make sure to set all the required env variables. The admin password is for the server app, not your bluesky account.

As I said, this gets the app to run and report positively to the healthcheck, now does someone want to test this?

P.S.: I have now created and deleted a user via curl, and verified that it persists a server restart.

[sfeldkamp]

This was helpful and validated the direction I was headed with it! I am working from a fork of bluesky-social/pds at https://github.com/sfeldkamp/cloudron-bluesky-pds.

Current status is that it's running! I can add invite codes through the app's web terminal with goat CLI. I can register a user account on the PDS and post, reply, like, and follow from it. These all are pushed to the Bluesky firehose and can be seen in the Bluesky App by other accounts.

Still to be debugged / tested:

• Newly created account on the PDS shows "Invalid Handle" warning in Bluesky App.
• Account migration with goat CLI to the PDS from a bsky.social PDS.
• Account migration with goat CLI from the PDS back to bsky.social PDS.
• General soak test to feel comfortable that all parts of the PDS are working correctly.

I have some time off later this week, so I think I can make progress with these things.

[sfeldkamp]

I have resolved the issue with Invalid Handle. The problem was not having a *.[app.domain.com] wildcard domain mapped for the app. There's unfortunately no way to do this with the CloudronManifest.json file during app installation so this will have to be a manual step for installers.

I've tested migrating an account from a Bluesky PDS and that seems good. Tested making and restoring backups in Cloudron. That seems good.

The only remaining work to be done, that I am aware of, is to implement the update mechanism. I'm uncertain whether I should (or even can) do that or if that is something the Cloudron staff will do as they prepare it for the App Store.

https://github.com/sfeldkamp/cloudron-bluesky-pds

If anyone has any guidance on what more I should do, or a better way to "submit" this to the staff let me know.

I will likely move my live account sometime soon to be self hosted on my custom app install, as I expect that process to take awhile. If anyone would like to try it out themselves or review the code, please feel free!

[robi]

@sfeldkamp see https://forum.cloudron.io/post/117766 for aliasDomains in CloudronManifest.json

[sfeldkamp]

@robi

That's the Cloudron CLI, not the CloudronManifest.json. I asked a follow up question though to clarify though, so thank you.

[sfeldkamp]

I added a checklist item to the CloudronManifest.json that makes it as clear as possible for the user to add the wildcard alias. I just couldn't find any way to do this automatically.

I've also moved my primary PDS on the ATProto network to be hosted on my Cloudron custom app. So far so good, no problems I've noticed!

[girish]

@sfeldkamp does the app have any UI?

[sfeldkamp]

@girish

/ - An informational landing page. You can see it here: https://at.sethfeldkamp.com/
/oauth - OAuth routes

Then data is available from
/xrpc - Http API
/.well-known/atproto-did - DID verification

That's all I can find for routes in the source code.

https://github.com/bluesky-social/atproto/tree/main/packages/pds

[girish]

@sfeldkamp yeah, that works for the Cloudron package.

[timconsidine]

@sfeldkamp well done !

Is "testing" a valid entry in CloudronVersions.json publishState ? It's creative but I was under impression that it is 'published' or 'revoked', binary choice. But I might be wrong. It's all rather new !

I'd put it as 'published' and just not list it in the community apps category for now.

[robi]

It seems like they're all in alpha testing until they make it into the app store for beta testing.

[sfeldkamp]

@timconsidine

I got this in the output for the cloudron versions add --help command. But I couldn't say if it has any effect or if it's just informational. It doesn't stop anyone from installing the app. Not sure about whether it would trigger updates.

[girish]

@sfeldkamp @timconsidine 'testing' state marks the release (just that version and not the app itself) as 'unstable' (just like cloudron's own app store packages). UI wise: when you install such a version, it will give a warning. Behavior wise: cloudron won't automatically update the app to that version .

It's really an advanced use case. We copied our app store behavior 1:1 for the community apps.

[sfeldkamp]

@girish

Thank you for explaining! It doesn't appear to be working that way for installs. I don't see any visual indicator for the Community App when installing it, nor on the app after it's installed. Here is the link to the versions file.

https://raw.githubusercontent.com/sfeldkamp/cloudron-bluesky-pds/main/CloudronVersions.json

Let me know if I should cross post this to support as a bug report (or elsewhere). I haven't tested whether "testing" prevents an automatic update from being discovered.
