Raw Blame History

+++ date = "2024-01-08" tags = ["bluesky","pds"] title = "blueskyをself-hostする" slug = "bluesky" +++

少し前にblueskyをself-host(セルフホスト)しました。

server url src
pds https://syu.is src
plc https://plc.syu.is src
mod https://mod.syu.is src
bgs https://bgs.syu.is src
appview https://api.syu.is src
web https://web.syu.is src

以前はbluesky(pds+appview)を動かしていたのですが、一般的にblueskyと呼ばれるものは複数のserverに依存しています。例えば、plc, bgsです。今ではpdsにあったappviewも分離しています。

bsky.teamがそれぞれのsandboxを用意してくれていますが、全部をself-hostしないといつか動かなくなります。

server env body
pds PDS_DID_PLC_URL https://plc.${host}
pds PDS_BSKY_APP_VIEW_URL https://api.${host}
pds PDS_BSKY_APP_VIEW_DID did:web:api.${host}
pds PDS_MOD_SERVICE_URL https://mod.${host}
pds PDS_MOD_SERVICE_DID did:web:mod.${host}
pds PDS_CRAWLERS https://bgs.${host}

nostrで活動されているikuradonさんが全部のserverをセルフホストしているのを見て、どうやら他のserverも動作できる環境にあるようだと思ったので立ててみました。なお、ikuradonさんに結構助けてもらった。

今回、syu.isというdomainを取りました。なお、.isはあまりおすすめしません。これはアイスランドが独自方針で管理している感じで、メール認証などが必要です。その他、様々な制限があります。

xxxは以下のコマンドなどで作成してもいいと思います。

$ openssl ecparam --name secp256k1 --genkey --noout --outform DER | tail --bytes=+8 | head --bytes=32 | xxd --plain --cols 32

SERVER_DID / SERVICE_SIGNING_KEY

SERVICE_SIGNING_KEYに入れる値はSERVER_DID=did:web:xxxの場合、ローカル環境で生成したもので構いません。しかし、SERVER_DID=did:plc:xxxを使用する場合はplcからkeyを登録します。

$ openssl ecparam --name secp256k1 --genkey --noout --outform DER | tail --bytes=+8 | head --bytes=32 | xxd --plain --cols 32

SERVICE_SIGNING_KEY=xxx

以下は現時点では必要ありません。

bsky(appview)のSERVER_DIDはdid:web:xxxという形式とdid:plc:xxxという形式を使えます。後者はplcに登録して使うものと思われ、連合が開始する際に重要になるかもしれません。

SERVICE_SIGNING_KEYはSERVER_DIDを取得したときのsign-keyだと思われます。

これはatprotoのdev-envでexampleが書かれています。

  static async create(cfg: BskyConfig): Promise<TestBsky> {
    // packages/crypto/tests/keypairs.test.ts
    const serviceKeypair = await Secp256k1Keypair.create({ exportable: true })
    console.log(`ROTATION_KEY=${serviceKeypair.did()}`)
    const exported = await serviceKeypair.export()
    const plcClient = new PlcClient(cfg.plcUrl)

    const port = cfg.port || (await getPort())
    const url = `http://localhost:${port}`
    const serverDid = await plcClient.createDid({
      signingKey: serviceKeypair.did(),
      rotationKeys: [serviceKeypair.did()],
      handle: 'bsky.test',
      pds: `http://localhost:${port}`,
      signer: serviceKeypair,
    })
    console.log(`SERVER_DID=${serverDid}`)

    const server = bsky.BskyAppView.create({
      db,
      redis: redisCache,
      config,
      algos: cfg.algos,
      imgInvalidator: cfg.imgInvalidator,
      signingKey: serviceKeypair,
    })

$ make deps
$ make build
$ make test

$ make run-dev-env

appviewをcreateする際のsigningKey: serviceKeypairの部分を見てください。objを使用しています。

つまり、signingKeyにobjを入れると動きますが、services/bsky/api.tsでは以下のような処理がなされます。

 const signingKey = await Secp256k1Keypair.import(env.serviceSigningKey)

didを作成したときにSecp256k1Keypairでimportできる値をSERVICE_SIGNING_KEYに入れてください。

あるいはコードを書き換えてobjをいれるのでもいけますが、現実的ではありません。

// const signingKey = await Secp256k1Keypair.import(env.serviceSigningKey)
const signingKey = process.env.SERVICE_SIGNING_OBJ

      keypair = await Secp256k1Keypair.create({ exportable: true })
      const exported = await keypair.export()
      imported = await Secp256k1Keypair.import(exported, { exportable: true })

      expect(keypair.did()).toBe(imported.did())

plcへの登録は以下のコマンドだと思われます。
