Starting Sync Gateway

[s.ande...@gmail.com]

I have installed Couchbase Server and Sync Gateway locally on my Mac. What I am trying to do is push the data in a Couchbase Lite database in an app to a Couchbase Server using Sync Gateway.

First baby step: attempt to get the Sync Gateway configured and running.

Using Couchbase Server's admin console I created a new bucket (e.g. mybucket). Confused about databases and buckets...I would have thought I would create a database, but there seems to be no option to do this so I created a bucket instead.

Created a config file for the Sync Gateway:

{
  "interface":"4984",
  "adminInterface":"4985",
  "databases":{
    "mybucket":{
      "server":"http://localhost:8091",
      "sync":`function(doc) { channel(doc.channels);}`
    }
  }
}

macbook:bin me$ ./sync_gateway /some/path/sync_gateway_config.json

What am I doing wrong?

One additional complication: The account I am logged in as on my Mac is a "standard" account. To install Couchbase Server successfully I had to switch to an "Administrator" account. As such, I run Couchbase Server and Sync Gateway from the command line, first logging in as an administrator using su - <admin account>.

Change the config file to have

"interface":":4984",
 "adminInterface":":4985",

(Note: Added a colon to indicate the port number), This is also explained in the help, if you try ./sync_gateway --help

Please note that these two are anyway not required as those are the default ports for the regular and admin interfaces.

For historical reasons Couchbase Server calls them “buckets” instead of “databases”. Same thing — they’re a namespace for mapping keys to documents.

There isn’t really any ‘installation’ step for Couchbase Server on a Mac; it’s just an application that you can put anywhere. What was the problem with using it from a non-admin account?

And there’s no need to run Sync Gateway from an admin account (whether or not you run Couchbase Server that way.)

If it’s more convenient, you can use the built-in ‘Walrus’ storage engine while you’re experimenting; it doesn’t require having Couchbase Server at all. Just edit the config and change the server URL to ‘walrus:’ (for a non-persistent database) or ‘walrus:/path/to/storage/dir/‘.

It doesn't start from my non-admin account - message is displayed "You can't open the application "%@" because it may be damaged or incomplete." Yet Couchbase starts successfully from if I start it from the command line using an administrator account. In addition not all the menu options under the Couchbase icon work, e.g. Open Admin Console or About Couchbase Server.

Thanks for the walrus info. I installed Couchbase Server and Sync Gateway locally as I expect I will use both in production/when my app is released.

Excellent, thanks Raja.

Further to my original post...

I now have Couchbase Server and Sync Gateway running. Using the demo app GrocerySync I am attempting to sync it with an empty grocery-sync database/bucket I created on Couchbase Server.

However, the URL http://mycomputer.local:4984/grocery-sync/ does not work, the app displays the error message "Error syncing 404 not_found." The Sync Gateway reports the same, "404 no such database grocery-sync".

NB: mycomputer was replaced with the actual name of my computer.

My Sync Gateway config file looks as follows:

{
  "interface":":4984",
  "adminInterface":":4985",
  "databases":{

    "sync_gateway":{
      "server":"http://stevesmacbook.local:8091",
      "bucket":"grocery-sync",
      "sync":`function(doc) {channel(doc.channels);}`
    }
  }
}

Any ideas?

}

The name of the database as per your configuration above is "sync_gateway", not "grocery-sync", which is probably why its erroring with a 404. You need to provide 2 buckets, one for sync_gateway and one for grocery-sync, something like this:

{

   "databases":{

        "sync_gateway":{

                "server":"http://localhost:8091",

                "bucket":"sync_gateway"

        },

        "grocery-sync": {

                "server":"http://localhost:8091",

                "bucket":"grocery-sync",

                "sync": `function(doc, oldDoc) { channel ("public");}`,

        }

  }

} 

The sync_gateway bucket is for some internal metadata that the sync gateway stores and then your actual bucket is for custom data.

Note: I have left off some details from your original configuration since they were the defaults anyway(for interface and admininterface)

No you don't! You only need the grocery-sync bucket.

Correct. The following config file seems to work:

{
    "databases":{
        "grocery-sync":{

            "server":"http://stevesmacbook.local:8091",
            "bucket":"grocery-sync",

            "users":{
                "GUEST":{
                    "disabled":false,
                    "admin_channels":["*"]
                }
            }
        }
    }
}
