Re: mesos docker vs native container

[Avinash Sridharan]

Docker does use bridged networking by default, but it uses linux bridges to
perform the bridging, there is no docker-proxy process. The problem with
docker bridge network is that the address space of the container spawned on
the docker bridge are different than the host network, so you need to
perform DNAT to get to any docker container on that bridge. The performance
hit is because of the DNAT. If you want container to container
communication on a single docker bridge, or if you configure the address
space of the docker bridge to be that of the host network (which in most
cases is not possible) you can get close to line speed performance.

Docker host networking is effectively attaching containers to the linux
host network namespace. So the performance results will be the same as that
of running a process natively on the host.

Re: mesos docker vs native container

[Jeff Schroeder]

I think you might be a bit confused now this all works. Docker by default
uses bridged networking, which by default spins up a little crappy
docker-proxy process for every port. You can disable docker-proxy and
instead use hairpin routing mode if you have a modern kernel. However, I'm
almost certain that any task you run via docker on mesos default to host
networking. Docker, LXC, mesos containers all use the Linux kernel network
namespace + perhaps some iptables/libnl magic for the networking bits.
Docker in host networking mode will do networking at mostly native speed. I
suggest you run iperf on mesos in the various configurations. It should be
pretty straightforward to test the overhead, but I suspect docker + host
networking will more than work. Give it a go and let us know!

Scheduler for distributed builds

[Paulo Gallo]

Hi,

I'm looking for a scheduler to do distributed builds, i.e. most of the
tasks would be short lived, like a few hundred ms long.

Is there's any Mesos based scheduler that would be a good fit for this?

Any help is appreciated.

Thanks,
-Paulo

PS: I know that Jenkins supports distributed builds and integrates with
Mesos, but we're looking for alternatives.

Re: mesos docker vs native container

Question is more related  to mesos.  I am thinking of using docker instead
of native (LXC?) containers but I suspect network performance decrease
which is important on big data workloads.
Can you explain why its not secured In host mode ?

Not sure though but my guess is that Mesos slave is unable to pull the

If you use the Docker default bridge network stack, I have heard of performance 
impact
up to 30% (depending on workload / kernel version / etc)

We use "host" networking which moderately reduces security but
all but eliminates the performance impact on the network.

You should make sure to do tests that this is true in your environment
but I believe it is possible to get near native performance if you
are willing to test things thoroughly and report issues as they arise.

Re: Launch docker container from Marathon UI

[June Taylor]

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)

 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

 So i guess it is a problem of bridging, i guess simply specify HOST

Re: Setting ulimits on mesos-slave

That is a good point - is the executor spun off as a different PID, if so
it would perhaps inherit a different fsize value.

Re: Setting ulimits on mesos-slave

[haosdent]

I disable the limit globally and retry set

```
limit fsize unlimited unlimited
```

in /etc/init/mesos-slave.conf after reboot. It works as well according to
check limits under /proc May you double check this in your side? I wonder
if the fszie only effective on Mesos Agent and doesn't work in your Mesos
executor.

RE: Launch docker container from Marathon UI

[Aaron Carey]

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.

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

--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

[June Taylor]

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.

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

RE: Launch docker container from Marathon UI

[Aaron Carey]

--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

Subject: Re: Launch docker container from Marathon UI

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

[Stefano Bianchi]

Thanks *Rad* Gruchalski, actually i'm trying to make a json file that
"translate" this command in marathon:

docker run --name some-wordpress --link some-mysql:mysql -d wordpress

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?

It says exactly what the problem is.  

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

Re: Launch docker container from Marathon UI

[June Taylor]

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

Re: Launch docker container from Marathon UI

[Stefano Bianchi]

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?

 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" ?

 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.

 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

[Stefano Bianchi]

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?

 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?

Re: Launch docker container from Marathon UI

[Stefano Bianchi]

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: Setting ulimits on mesos-slave

Perhaps the "unlimited" keyword is what is not working? What should be
specified for Unlimited?

Re: Launch docker container from Marathon UI

[June Taylor]

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 , 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": , "hostPort": 0 }
  ]
}
  }
}

Re: Launch docker container from Marathon UI

[haosdent]

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.

[aishwarya.adyanthaya]

Hi,

I tried running python application through Marathon GUI 
(https://docs.docker.com/engine/userguide/containers/usingdocker/).The 
application is delaying to deploy and  the task is failing .

This what I am getting the error:-

Task id hello-world.8b610fde-0b97-11e6-8964-fa163e724e71
State TASK_FAILED
Message Abnormal executor termination
Host 30.30.x.x

Mesos Details 
link

I'm able to run the docker containers (ex.Hello-world) through the cli of the 
machine but I'm unable to get the application running in marathon GUI.

Thank you,
Aishwarya Adyanthaya
