The store comes apart into the four roles it always had
`weed server -s3` was never one thing. Master, volume, filer and the S3 gateway ran as four goroutines under one process, on one volume, sharing one fate. Splitting them into four containers changes nothing a client can see — the same bucket answers on the same port — but it makes three things possible that were not: the SeaweedFS admin UI, which wants a cluster to look at; a restart or an upgrade of one role without the others; and, eventually, a second volume server somewhere else. A fifth container carries the panel itself. The single-process files stay exactly as they were. These are `.split.` twins beside them, four in all, one per folder per shape, each with the .env example of the same name that both READMEs already promise. Identities are the part that could not simply be copied across. SeaweedFS picks its credentials from one source, in order: an -s3.config file, the filer's IAM store, then AWS_ACCESS_KEY_ID and its secret — and a higher source replaces a lower one rather than adding to it. The existing files use the env pair, which is fine precisely because nothing else writes identities there. Hand somebody a panel that can, and the first user they create lands in the filer's store, the store outranks the environment, and PocketBase's key stops existing — with the first failed upload as the notification. So the gateway here is started with no config file and no AWS_* at all, and the init container seeds PocketBase's identity into the filer's store instead: the same store the panel writes. One source of truth, PocketBase's key sitting in Object Store → Users beside every other, keys minted there picked up without a restart, and a rotated PB_S3_SECRET re-applied in place on the next boot rather than added as a second identity. That seeding is now allowed to fail. The bucket-create it grew out of was best-effort — `|| true`, on the reasoning that the API Server's own S3 check would report a gateway that was genuinely unreachable. That reasoning does not survive the change: a gateway whose IAM store is empty does not refuse anyone, it serves everyone, and the bucket would be wide open rather than unreachable. So the step ends by grepping the configuration back for the access key, the gateway waits on it completing successfully, and a seed that did not land stops the stack instead of opening it. The prod files publish the gateway and the panel, both on loopback, and nothing else. Port 8080 on the volume server hands out file content by file id with no authentication of any kind — the S3 credentials have no bearing on it — so publishing it would publish every attachment in the stack, and the panel shows what that port and the master's would. The panel's own password is required rather than defaulted, because weed serves it with authentication switched off entirely when it is empty, and a page that mints bucket credentials is the bucket. It is passed as WEED_ADMIN_PASSWORD rather than a flag so it stays off the process command line, and SEAWEED_ADMIN_BIND is the knob a remote host needs, named after PB_BIND and API_BIND for the same reason. Master, volume and filer share one /data mount rather than taking three of their own. That is precisely the layout `weed server -dir=/data` writes — the master's raft state, the volume's .dat and .idx, the filer's filerldb2, no two of them naming the same file — so a stack can move between the single-process file and its twin in either direction with nothing to migrate. A second volume server would need its own, and the files say so where somebody would go looking. The dev files map the volume server to 8081 on the host: 8080 there is already the API Server, and in the all-in-one it is the API Server inside the image. Unexercised: written on a machine without Docker, so none of the four has been brought up. Every flag, health path and env name was read out of the pinned 4.45 source rather than recalled — -mdir, -volumeSizeLimitMB, -defaultStoreDir, -max, admin's -master and -dataDir and WEED_ADMIN_*, the filer's and gateway's /healthz, the panel's unauthenticated /health — and the four files were parsed, interpolated against their examples, and checked for duplicate host ports. A `docker compose config` on the target host is still the first thing to run. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |
