Launch docker container from Marathon UI

Hi guys

i'm trying to follow the instructions on mesosphere documentation, but it
is a little bit unlear for me that i am new to this world.
i' would like to launch a wordpress container, present on docker hub here
https://hub.docker.com/_/wordpress/ , from marathon UI but i don't
understand the mechanism.
I understood that i don't have to specify a command in "Command" field, but
i don't know how to fill the dockers fields in marathon UI to launch
wordpress container.
Could you please help me or tell me where i can find a clearer
documentation?

Thanks.

The docker container you're using seems to be expecting environment
variables which you have not supplied.

RE: Launch docker container from Marathon UI

Posted by Aaron Carey <ac...@ilm.com>.

Then you need to tell marathon to run the mysql container first, and then submit the wordpress container.

Sorry I think I misunderstood!

My problem is this, where can i find the mysql container? I have just said to marathon to rim a wordpress docker container, without specify mysql one.

If you run the wordpress container on a different host to the mysql container and use --link on the command line, does that work?

Hi Aaron
Actually both mesos-dns and calico are running even though these containers im running are not, yet, using the calico ipaddr specific in json description.
So i guess it is a problem of bridging, i guess simply specify HOST option on container field in Marathon UI

Il 26/apr/2016 16:59, "Aaron Carey" <ac...@ilm.com>> ha scritto:
--link in docker should really be avoided when using marathon/mesos as it implies the containers are on the same host, but this will not always be the case when mesos schedules your containers (also I think it's being deprecated in docker anyway.. not sure though?).

This problem looks like one of service discovery within the mesos cluster: how does one service contact the other when it doesn't know which host the other service may have landed on?

There are several different solutions for service discovery, you can look into some like Project Calico to offer a network layer to docker or try dns based solutions like Mesos-dns or Consul (along with mesos-consul). I think marathon also has some concept of service discovery built in too if you use something like haproxy.

I hope this helps!

Aaron

Stefano,

The docker run flag --link is intended to connect the container to another running container. I do not know how this would operate in marathon. Perhaps it would be an application group which starts up the mysql docker image first, then the Wordpress docker image after it.

My problem is that i don't know how to do that, i tried to fill environment variable fields:

But in this way the app does not work as well. How can i configure these env variables?

It says exactly what the problem is.

Start a marathon task with correct environment variables in env and you will be fine.

I am able to link the correspondent field in the marathon UI with what is written in this json.
What i need to understand is, what i should write in:

i mean, with what i have to replace group and image?

Re: Launch docker container from Marathon UI

Posted by June Taylor <ju...@umn.edu>.

The answer to your question is not very simple. I am still figuring this
out myself, but you can look at certain projects such as mesos-dns which
publish SRV records for running docker containers, allowing you to
programmatically find services you have started up. For example, here I
have started up a container that publishes an HTTP interface. Mesos starts
it up on a random node, and assigns it a random high TCP port. All I know
is that it is called "tomsflask" and that it has a TCP port. With this
information, I ask the mesos-dns system where is it running, as you can see
in the NSLOOKUP command below, requesting the SRV record which mesos-dns
automatically created when the container started. In the next command, I
use CURL to show what content is being produced on the port (31427) and
hostname I had received from the SRV command.

june@cluster:~$ nslookup -type=SRV _tomsflask._tcp.marathon.mesos

_tomsflask._tcp.marathon.mesos service = 0 0 31427 tomsflask-5p8ho-s83.
marathon.slave.mesos.

june@cluster:~$ curl http://tomsflask-5p8ho-s83.marathon.slave.mesos:31427

Hello World from Flask (default)

Re: Launch docker container from Marathon UI

Posted by Stefano Bianchi <ja...@gmail.com>.

ok now i started hadoop, i have just to wait the pull process end.
mesos assign a port to this task but if i go to the SLAVE_IP:PORT i cannot
see anything.
On which pot hadoop is commonly viewable?

Re: Launch docker container from Marathon UI

Posted by Stefano Bianchi <ja...@gmail.com>.

Since i already mentioned, anyone of you tried to run hadoop as docker
container from marathon?
i tried with this simple json:

{

  "id": "hadoop",

  "cpus": 1,

  "mem": 1000,

  "container": {

    "type": "DOCKER",

    "docker": {

      "image": "sequenceiq/hadoop-docker:2.7.1",

      "network": "HOST"

    }

  }

}

the app appears as running but the bar is yellow and on mesos i see staged.
The container is more or less 800 MB probably i need to wait that pull
operation ends? Maybe the i need to give more ram and also some storage?

Re: Launch docker container from Marathon UI

Posted by Stefano Bianchi <ja...@gmail.com>.

Thank you Guillermo Rodriguez
I will try your solution as soon as possible since wordpress is not the
goal task i wanna run, it was just an example to understand how to launch a
docker container, and of course i have chosen the easiest one :P
However, i correctly run Jenkins, Jupyter and Owncloud, now i'm trying to
do the same with hadoop.
Thanks to all guys.

Re: Launch docker container from Marathon UI

Posted by Guillermo Rodriguez <gu...@spritekin.com>.

Sorry if it has been answered before.
 You need mesos-dns. 
 Start your mysql service on marathon, then mesos-dns will have an entry called mysql.marathon.mesos regardless of where the service is started you can always use that URL to resolve the mysql service.
  
 Then you start wordpress and specify that your mysql server is mysql.marathon.mesos. If you need to setup an env variable in the wordpress definition you use the env section like:
 {
  "id": "wordpress",
  "cpus": 1,
  "mem": 512,
  "container": {
    "type": "DOCKER",
    "docker": {
      "image": "wordpress",
      "network": "HOST"
    }
  },
  "env": {
      "WORDPRESS_DB_HOST": "mysql.marathon.mesos:3306",
  }
 }
  
 Marathon also allows to add dependencies on startup so you can request marathon to start the mysql service before starting the wordpress.service. Search for the Marathon REST API for more information.
  
 Luck!

Hi Aaron
Actually both mesos-dns and calico are running even though these containers im running are not, yet, using the calico ipaddr specific in json description.
So i guess it is a problem of bridging, i guess simply specify HOST option on container field in Marathon UI  Il 26/apr/2016 16:59, "Aaron Carey" <ac...@ilm.com> ha scritto:    --link in docker should really be avoided when using marathon/mesos as it implies the containers are on the same host, but this will not always be the case when mesos schedules your containers (also I think it's being deprecated in docker anyway.. not sure though?).

This problem looks like one of service discovery within the mesos cluster: how does one service contact the other when it doesn't know which host the other service may have landed on?

There are several different solutions for service discovery, you can look into some like Project Calico to offer a network layer to docker or try dns based solutions like Mesos-dns or Consul (along with mesos-consul). I think marathon also has some concept of service discovery built in too if you use something like haproxy.

I hope this helps!

  Stefano,  
 The docker run flag --link is intended to connect the container to another running container. I do not know how this would operate in marathon. Perhaps it would be an application group which starts up the mysql docker image first, then the Wordpress docker image after it.

Re: Launch docker container from Marathon UI

Posted by June Taylor <ju...@umn.edu>.

Stefano,

You would want to search for an appropriate image on Docker Hub. Here is
one I have NO experience with: https://hub.docker.com/_/mysql/

You would then need to learn about how the image is expecting to be
configured, so you can set it up appropriately.

This is not really a fully thought out solution. I assume you're trying to
do this for more of a proof-of-concept, though. So it may be fine for your
needs.

Re: Launch docker container from Marathon UI

Posted by Rad Gruchalski <ra...@gruchalski.com>.

Marathon does not know it has to run it. You need to tell Marathon to start mysql container and then tell your wordpress container where is your mysql.

I think marathon also has some concept of service discovery built in too if you use something like haproxy.

RE: Launch docker container from Marathon UI

Posted by Aaron Carey <ac...@ilm.com>.

If you run the wordpress container on a different host to the mysql container and use --link on the command line, does that work?

Hi Aaron
Actually both mesos-dns and calico are running even though these containers im running are not, yet, using the calico ipaddr specific in json description.
So i guess it is a problem of bridging, i guess simply specify HOST option on container field in Marathon UI

There are several different solutions for service discovery, you can look into some like Project Calico to offer a network layer to docker or try dns based solutions like Mesos-dns or Consul (along with mesos-consul). I think marathon also has some concept of service discovery built in too if you use something like haproxy.

I hope this helps!

Stefano,

The docker run flag --link is intended to connect the container to another running container. I do not know how this would operate in marathon. Perhaps it would be an application group which starts up the mysql docker image first, then the Wordpress docker image after it.

i guess the error is relate to the fact that i'm not specifying --link some-mysql:mysql
My problem is that i don't know how to do that, i tried to fill environment variable fields:

Key = link
Value = some-mysql:mysql

But in this way the app does not work as well. How can i configure these env variables?

2016-04-26 16:01 GMT+02:00 Rad Gruchalski <ra...@gruchalski.com>>:
It says exactly what the problem is.

Start a marathon task with correct environment variables in env and you will be fine.

June i tried to run your json, but the task is waiting, and if starts it failed immediately.

I guess because i did not type this commands:


  1.

echo 'docker,mesos' > /etc/mesos-slave/containerizers

  2.

$ echo '5mins' > /etc/mesos-slave/executor_registration_timeout

Could it be the problem?

thanks haosdent.
actually i have run this kind of apps through rest api.
Now i want learn how to laung docker files. I found this exaple:


{
  "container": {
    "type": "DOCKER",
    "docker": {
      "network": "HOST",
      "image": "group/image"
    },
    "volumes": [
      {
        "containerPath": "/etc/a",
        "hostPath": "/var/data/a",
        "mode": "RO"
      },
      {
        "containerPath": "/etc/b",
        "hostPath": "/var/data/b",
        "mode": "RW"
      }
    ]
  }
}

I am able to link the correspondent field in the marathon UI with what is written in this json.
What i need to understand is, what i should write in:

 "image": "group/image"

i mean, with what i have to replace group and image?
For instance, if i would run wordpress container on docker hub what i should put replacing "group/image" ?







2016-04-26 14:30 GMT+02:00 haosdent <ha...@gmail.com>>:
This is marathon REST API document: https://mesosphere.github.io/marathon/docs/rest-api.html#post-v2-apps . Usually we define a task json file and call the rest api.

For example, create tasks.json which content is

```
{
"id": "/test-sleep",
"cmd": "sleep 200"
}
```

And

```
curl -X POST -H "Content-type: application/json" http://${YOUR_MARATHON_ADDR}:8080/v2/apps -d @tasks.json
```

You could find more field definitions in their document.

i' would like to launch a wordpress container, present on docker hub here https://hub.docker.com/_/wordpress/ , from marathon UI but i don't understand the mechanism.
I understood that i don't have to specify a command in "Command" field, but i don't know how to fill the dockers fields in marathon UI to launch wordpress container.
Could you please help me or tell me where i can find a clearer documentation?

Thanks.

Re: Launch docker container from Marathon UI

Posted by June Taylor <ju...@umn.edu>.

Stefano,

The docker run flag --link is intended to connect the container to another
running container. I do not know how this would operate in marathon.
Perhaps it would be an application group which starts up the mysql docker
image first, then the Wordpress docker image after it.

Re: Launch docker container from Marathon UI

Posted by Stefano Bianchi <ja...@gmail.com>.

jupyter is working fine.
i tried to run wordpress and i get this error in stderr of mesos:

error: missing WORDPRESS_DB_HOST and MYSQL_PORT_3306_TCP environment
variables

  Did you forget to --link some_mysql_container:mysql or set an external db

  with -e WORDPRESS_DB_HOST=hostname:port?



Some one of you know this issue?

i have done these 2 commands, now jupyter is in deploying in marathon,
staging in mesos.
Is there some additional configuration needed?

Re: Launch docker container from Marathon UI

Posted by Stefano Bianchi <ja...@gmail.com>.

June i tried to run your json, but the task is waiting, and if starts it
failed immediately.

I guess because i did not type this commands:


   1.

   echo 'docker,mesos' > /etc/mesos-slave/containerizers

   2.

   $ echo '5mins' > /etc/mesos-slave/executor_registration_timeout


Could it be the problem?

Re: Launch docker container from Marathon UI

Posted by June Taylor <ju...@umn.edu>.

Stefano,

Per your earlier question, "group/image" refers to the path you will see in
the Docker Hub website on the right side, after the "docker pull" command.
In the Jupyter Notebook example I gave you, jupyter is the group, and
notebook is the image, with the / literal separating them.

Re: Launch docker container from Marathon UI

Posted by Stefano Bianchi <ja...@gmail.com>.

thanks haosdent.
actually i have run this kind of apps through rest api.
Now i want learn how to laung docker files. I found this exaple:

{
  "container": {
    "type": "DOCKER",
    "docker": {
      "network": "HOST",
      "image": "group/image"
    },
    "volumes": [
      {
        "containerPath": "/etc/a",
        "hostPath": "/var/data/a",
        "mode": "RO"
      },
      {
        "containerPath": "/etc/b",
        "hostPath": "/var/data/b",
        "mode": "RW"
      }
    ]
  }}


I am able to link the correspondent field in the marathon UI with what is
written in this json.
What i need to understand is, what i should write in:

 "image": "group/image"

i mean, with what i have to replace group and image?
For instance, if i would run wordpress container on docker hub what i
should put replacing "group/image" ?

Re: Launch docker container from Marathon UI

Posted by haosdent <ha...@gmail.com>.

This is marathon REST API document:
https://mesosphere.github.io/marathon/docs/rest-api.html#post-v2-apps .
Usually we define a task json file and call the rest api.

For example, create tasks.json which content is

```
{
"id": "/test-sleep",
"cmd": "sleep 200"
}
```

And

```
curl -X POST -H "Content-type: application/json"
http://${YOUR_MARATHON_ADDR}:8080/v2/apps
-d @tasks.json
```

You could find more field definitions in their document.

Re: Launch docker container from Marathon UI

Posted by June Taylor <ju...@umn.edu>.

Stefano,

I hope this information is helpful:

You should specify the docker hub path, which is the what you can see after
the Docker Pull command on the Hub page. In your case, simply the word:
"wordpress" without quotes, is what you would use as the Image.

You will also need to specify port bindings (which I am still learning
about so welcome corrections).

For example, here is how you would use the Jupyter Notebook from Docker
Hub. The container is publishing the Notebook interface on port 8888, and
by specifying host port 0, a random port is chosen by Marathon, which you
will see in the Marathon interface under the Running Instances as a
clickable link to load the HTTP interface.

{
  "id": "notebook",
  "cpus": 1,
  "mem": 512,
  "container": {
    "type": "DOCKER",
    "docker": {
      "image": "jupyter/notebook",
      "network": "BRIDGE",
      "portMappings": [
        { "containerPort": 8888, "hostPort": 0 }
      ]
    }
  }
}
