I am using docker-compose to run couchbase server and sync gateway. I am following instructions as described in README.md.

Couchbase is running fine. I was able to start and configure it. However Sync Gateway throwing an error:

WARNING: Error from Incr in sequence allocator (0) - attempt (3/3): EOF -- db.(*sequenceAllocator).incrWithRetry() at sequence_allocator.go:88

And then

FATAL: Error opening database: Unable to increment sequence: EOF -- rest.RunServer() at config.go:758

Full logs:

I think it might be related to the order in which the containers are started. Note this SG issues which mentions that same error when the underlying couchbase server bucket is deleted:

https://github.com/couchbase/sync_gateway/issues/1655

So that error might have happened when you were configuring couchbase server.

The docker compose script looks flawed in the sense that SG will try to connect to an un-configured Sync Gateway.

Is it possible to restart one container in the docker compose?

If not, I'd recommend just ignoring the docker compose and starting the containers individually, and make sure they are in the same network.

@rajagp do you have that blog post about Couchbase + Sync Gateway in docker handy?

Tried to restart just sync-gateway with command docker-compose restart sync-gateway. Sync Gateway restarts and fail again with the same error.
