Docker example in Marathon Application Basics page fails to run #3399

Closed natemurthy closed 8 years ago

natemurthy commented 8 years ago

I have a 4 node (1 master + 3 workers) Mesos/Marathon cluster running in EC2 behind a VPC. I'm following the instructions on this page:

https://mesosphere.github.io/marathon/docs/application-basics.html

and could successfully deploy, launch, and run the first two examples on the page with no problem. But I'm having issues running the basic-3.json example using Docker containers. Below are some screenshots from my web dashboards:

marathon-docker-1

marathon-docker-2

marathon-docker-3

In my Marathon dashboard I am observing the basic-3 app looping into Waiting -> Deploying -> Delayed states and repeating this over and over again.

marathon-docker-4

And in Mesos I'm just seeing everything complete with FAILED state over and over for the same task. I manually installed Docker on all my worker nodes. Are there some additional configurations I need to make that were omitted in the instructions above?

you should provide the task parameters for analysing. or check if your docker container could run locally without the deployment of marathon.

Hey @natemurthy . Could you also post a screenshot with the Last Task Failure in the Debug Tab. That would be helpful to see what is going on. Thank you.

@junneyang yes, i can run docker container locally on my worker nodes:

$ sudo docker run hello-world

Hello from Docker.
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash
