What happened?

Hello,

I want to run the testcontainer using direct connection instead of gateway connection for Cosmos DB.
https://www.testcontainers.org/modules/azure/

After following this tutorial I was able to run on gateway mode, but when I try to run on direct I get Fail to reach global gateway [https://localhost:54950]

I've exposed the missing ports 10251, 10252, 10253, 10254 but the error still goes on.

When I use the image directly on Docker I am able to run the tests without any issues.

After 2 days of trying I was able to make it work.

It seems like it's some issue with the SDK or something like that, but here's the dirty fix to make it work with testContainers:

Creating the emulator:

    static {
        try {
            Consumer<CreateContainerCmd> cmd =
                    e -> e.withPortBindings(
                            new PortBinding(Ports.Binding.bindPort(8081), new ExposedPort(8081)),
                            new PortBinding(Ports.Binding.bindPort(10251), new ExposedPort(10251)),
                            new PortBinding(Ports.Binding.bindPort(10252), new ExposedPort(10252)),
                            new PortBinding(Ports.Binding.bindPort(10253), new ExposedPort(10253)),
                            new PortBinding(Ports.Binding.bindPort(10254), new ExposedPort(10254))
                    );
            emulator = new CosmosDBEmulatorContainer(
                DockerImageName.parse("mcr.microsoft.com/cosmosdb/linux/azure-cosmos-emulator"))
                    .withCreateContainerCmdModifier(cmd)
                    .withExposedPorts(8081, 10251, 10252, 10253, 10254)
                    .withEnv("AZURE_COSMOS_EMULATOR_IP_ADDRESS_OVERRIDE", InetAddress.getLocalHost().getHostAddress())
                    .withEnv("AZURE_COSMOS_EMULATOR_PARTITION_COUNT", "3")
                    .withEnv("AZURE_COSMOS_EMULATOR_ENABLE_DATA_PERSISTENCE", "true");
            emulator.start();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

Creating the client:

    public static CosmosAsyncClient createClient(final DirectConnectionConfig directConnectionConfig) {
        return new CosmosClientBuilder()
                .endpointDiscoveryEnabled(false)
                .endpoint(emulator.getEmulatorEndpoint())
                .key(emulator.getEmulatorKey())
                .directMode(directConnectionConfig)
                .contentResponseOnWriteEnabled(false)
                .buildAsyncClient();
    }

Would it be valuable for the project it I contribute by raising a PR even using this deprecated e.withPortBindings method? If not, at least a note about this on the Testcontainers Azure module page would be nice.

I had to map to fixed ports, probably related to this issue on cosmos-emulator repo
Azure/azure-cosmos-db-emulator-docker#50

Hi @fabriciorby

No need to do all of that. I found that the sdk is looking for port 10251 which is not open on cosmodbemulator and there is no a way to configure it to a random port via env variable, for example. However, you can do something like this.

Add the following dependency com.github.terma:javaniotcpproxy:1.5

CosmosDBEmulatorContainer emulator = new CosmosDBEmulatorContainer(
                DockerImageName.parse("mcr.microsoft.com/cosmosdb/linux/azure-cosmos-emulator:latest")
)
.withExposedPorts(8081, 10251)
.withEnv("AZURE_COSMOS_EMULATOR_IP_ADDRESS_OVERRIDE", InetAddress.getLocalHost().getHostAddress())
emulator.start();

StaticTcpProxyConfig tcpProxyConfig = new StaticTcpProxyConfig(10251, emulator.getHost(), emulator.getMappedPort(10251));
            tcpProxyConfig.setWorkerCount(1);
            TcpProxy tcpProxy = new TcpProxy(tcpProxyConfig);
            tcpProxy.start();

I hope this can help. I have provided feedback via email to the cosmodb team about providing a way to override the port via env variable in the sdk.

@eddumelendez

Hey @eddumelendez, thanks for your reply!

I've tried the code above and it did not work. I tried running by exposing only the port 8081 and 10251 with my solution and it did not work as well.

Tried again proxying 10251, 10252, 10253, 10254 and it was successful, I think it's needed to expose all 4 ports.

I liked this solution, so I'll keep it. 😁👍🏻

By the way, nice to know about this lib.

I think there is a different setup on your side which requires more ports. TBH, don't know much about cosmodb and the suggestion is only a workaround due to it will be fixing ports. We will be taking this issue as an enhancement to support direct mode.

@fabriciorby

I had same issue and Fabricio's solution works for me.
@fabriciorby to avoid deprecated methods, use e -> e.getHostConfig().withPortBindings
