Hi, I've setup a single-node Couchbase 5.0.1 cluster in Docker on Mac OS X. Cluster is setup in Docker so http://127.0.0.1:8091/pools/default gives me the following hostname 172.25.0.2:8091. This hostname is not accessible from Mac OS, which is why as I suspect couchbase-rs can't connect to it.

Here is a sample program:

use couchbase::*;
use futures::executor::block_on;

pub fn main() {
    env_logger::init();
    let cluster = Cluster::connect("http://localhost:8091", "Administrator", "password");
    let bucket = cluster.bucket("test");
    let collection = bucket.default_collection();
    match block_on(collection.get("airline_10123", GetOptions::default())) {
        Ok(r) => println!("get result: {:?}", r),
        Err(e) => println!("get failed! {}", e),
    };
}

Here is the log:

At the same time, both Java and Python clients can connect to the cluster without any troubles.

@sadolit did you do it as described here? https://docs.couchbase.com/server/current/install/getting-started-docker.html#section_jvt_zvj_42b It is important that the ports are correctly exposed. Also your connection string is likely wrong, it should be couchbase://localhost, or for simplicity just localhost.

@daschl Yes, all ports are open and I can access this cluster from the web UI, Java, and Python clients.
Regarding connections strings: I tried couchbase://localhost, http://localhost:8091, and couchbase://127.0.0.1, confirming each time that it works in Python, but not in Rust.

@sadolit can you please enable more logging so we can debug? Something like RUST_LOG=couchbase=trace cargo run should do.

@daschl Sure! I changed the connection string to localhost just to make sure. I've let it run for some time as it gets into infinite loop.

Here is a sample Python script that runs fine:

from couchbase.cluster import Cluster, ClusterOptions
from couchbase_core.cluster import PasswordAuthenticator
cluster = Cluster("couchbase://localhost", ClusterOptions( PasswordAuthenticator("Administrator", "password")))
g = cluster.bucket("test").get("test", quiet=True)
print(g)'

Output:

ValueResult<rc=0x12D[LCB_ERR_DOCUMENT_NOT_FOUND (301)], key='test', value=None, cas=0x0, flags=0x0, tracing_context=0, tracing_output={'s': 'kv:Unknown', 'c': 'a52c1bb6b0f46723/52b017f7be00fdbc', 'i': 2322031628865647233, 'b': 'test', 'l': '127.0.0.1:62521', 'r': 'localhost:11210', 't': 2500000}>

Here is also docker port output:

$ docker port couchbase
11210/tcp -> 0.0.0.0:11210
11211/tcp -> 0.0.0.0:11211
8091/tcp -> 0.0.0.0:8091

@sadolit which python SDK version are you using? this looks like an "sdk 2" api and potentially a very different libcouchbase version
