use docker-client api to start container in Java project

Question

I am now using docker client api https://github.com/docker-java/docker-java in my Java project:

CreateContainerResponse container = 
    dockerClient
        .createContainerCmd("ubuntu:java7")
        .withCmd("true")
        .exec();
dockerClient
    .startContainerCmd(container.getId())
    .exec();

When I start a new container using docker client api,the container is created,but i also finished.I use command "sudo docker ps" to list the running container now, what I created is not shown.I want to create the running container in my Java project using the docker client api,how should I do? Thanks.

Your container is probably not running. docker ps -a will show you all containers, including the stopped ones. — jannis

You say you have some code. Edit your question and include it. — jannis

I am not sure whats your usecase here. I think you are starting container in attached mode. As soon as you are done, the container exits. And you want that container to persist.

Use

.withTty(true)

while creating the container to detach.
