I am trying to run a docker image using the following code. But the container is exiting immediately after starting. I don't find -d params at creating container. how to do?
HostConfig hostConfig = new HostConfig();
DefaultDockerClientConfig.Builder config = DefaultDockerClientConfig.createDefaultConfigBuilder();
DockerClient dockerClient = DockerClientBuilder.getInstance(config).build();
CreateContainerCmd createContainerCmd = dockerClient.createContainerCmd(image);
createContainerCmd.withTty(true)
.withAttachStdout(true)
.withStdinOpen(true)
.withAttachStdout(true)
.withAttachStderr(true)
.withAttachStdin(true)
.withName(containerName)
.withHostConfig(hostConfig);
String containerId = createContainerCmd.exec().getId();
dockerClient.startContainerCmd(containerId).exec();
Could anybody help me to understand the how to keep the container up and running?
I am trying to access the grpc server which exposes 9000 port and is running as docker container.
I am using .net core client to connect to the server.It works perfectly fine when GRPC server is not running as a docker container.
I have tried using both the "localhost","dockerconatiner-ip" while creating the channel from client.I am running the grpc server on "0.0.0.0"and port 9000.
docker commands:
docker run -p 9000:9000 -a stdin -a stdout -it
Error:
Status(StatusCode=Unavailable, Detail="DNS resolution failed")
dockerfile:

Server server = new Server

Ports = { new ServerPort("0.0.0.0", 9000, ServerCredentials.Insecure) },

};
server.Start();
Console.WriteLine("starting server");

Console.ReadKey();
server.ShutdownAsync().Wait();
Console.WriteLine("Grpc Server stopped");
}
catch(Exception ex)

}

Test service has a method to print received text to console.
I have a NET Core Console Application which has a socket binded to a port.
I have dockerized this application and i am trying to expose the binded port.The program shows its output correctly when i use docker attach [instance] .However when trying to connect with Telnet i get the error:

P.S As someone pointed out i tried exposing with both 127.0.0.1 and 0.0.0.0 from the .NET Application. to no avail.
Try to bind the application to 0.0.0.0 instead of 127.0.0.1. This will solve your problem.
set .env like the followings about Server address.
APP_URL=http://localhost:8000
APP_DOMAIN=localhost
I am using apache2 (docker container) as web server.
under this condition, to test with dusk, started up selenium/standalone-chrome as another container.
docker run -p 4444:4444 --name selenium --link apache2:apache2 -d selenium/standalone-chrome
to confirm the connection between docker containers,
used the following commands
docker exec -it selenium bash,
cat /etc/hosts/
result was
172.17.0.6 apache2 a1c15575e4c8
also confirmed ping apache2 from selenium container.
but from here, couldn't do dusk test using following command.
when I check the browser response, there was no contents.
docker exec apache2 php artisan dusk
I think setting is wrong. but can't notice it.
could you help?
the following is php source code.

I'm running aerospike server in docker.

I found the ip address of docker using below command.

Now I am trying to connect to the aerospike server in docker using java client in host machine.
public class AerospikeDemo {
public static void main(String []args) {
AerospikeClient client = new AerospikeClient("172.17.0.2", 3000);
Key key = new Key("test", "demo", "putgetkey");
//Key key2 = new Key("1", "2", "3");
Bin bin1 = new Bin("bin1", "value1");
Bin bin2 = new Bin("bin2", "value2");
Bin bin3 = new Bin("bin2", "value3");
// Write a record
client.put(null, key, bin1, bin2, bin3);
// Read a record
Record record = client.get(null, key);
System.out.println("record is "+ record);
System.out.println("record bins is " + record.bins);
client.close();
}
}
When I run the above program, I'm getting below error -

I've tried both AerospikeClient("172.17.0.2", 3000) and AerospikeClient("localhost", 3000)
I see in the Dockerfile the port 3000 is exposed to the host but I'm not sure why I'm not able to use the aerospike server in the docker.
The IP 172.17.0.2 is only accessible within Docker (therefore you can use another container to connect). In case you want to connect from your host you need to map the respective port.
docker run -d --name aerospike -p 3000:3000 aerospike/aerospike-server
Afterwards you can use:
AerospikeClient client = new AerospikeClient("localhost", 3000);
