Instant Whales

API Server to run/kill Docker containers with expires time. This server is for internal use. Don't publish the server on the Internet directly.

The benefit of this server is that it can handle 'expires' of containers. Instant Whales shouldn't handle backends too much. Basically, it should be solved by Kubernetes, AWS ECS or so.

API

GET /containers

Return running containers.

POST /containers

Run a new container. Requests should be like this.

{
  "image": "redis",
  "expires": 60,
  "memory": 32
}

image: Docker image name to run
expires: Seconds to run the container. After specified seconds, the container will be killed.
- Specify 0 not to expire the container
memory: Memory amount to allocate for the container (as MB).

Responses will be like this.

{
    "containerId": "90b4833113325a234fb7c4477a2fcd0c40bcda183527bc68c9aad51ac3a4eb52",
    "image": "redis",
    "port": "32776",
    "ports": {
        "6379/tcp": [
            {

                "HostPort": "32776"
            }
        ]
    },
    "expires": 180
}
