Re: LIBPROCESS_IP
Hendrik, It looks to me that Mesos always pass LIBPROCESS_IP to executor if agent's LIBPROCESS_IP environment variable is set: https://github.com/apache/mesos/blob/1.4.x/src/slave/slave.cpp#L8106-L8115 Maybe that's the difference between your vanilla Mesos, and DC/OS Mesos config? - Jie On Fri, May 18, 2018 at 2:29 AM, Hendrik Haddorp <hendrik.hadd...@gmx.net> wrote: > Hi, > > I had been using Mesos 1.4.1 and now tried out a DC/OS setup (1.9.4) and > noticed that the env variable LIBPROCESS_IP was set.

LIBPROCESS_IP
Hi, I had been using Mesos 1.4.1 and now tried out a DC/OS setup (1.9.4) and noticed that the env variable LIBPROCESS_IP was set. This broke my scheduler (running as a docker container on Marathon). Things worked fine again once I unset the variable in my startup script. I'm now wondering why LIBPROCESS_IP is being set. Is there maybe some config setting in Mesos that leads to that? MESOS-3553 and MESOS-3740 are for example about LIBPROCESS_IP being passed on but as I didn't get it passed in on Mesos 1.4.1 this is odd. thanks, Hendrik
Re: Set LIBPROCESS_IP for frameworks launched with marathon
Tom, The correct IP address doesn't really have a predictable pattern, because we run in several different environments. Vagrant for dev, internal cloud for staging, public cloud for production. I did try this approach initially, but wasn't able to make it work reliably in all environments. I don't know much about mesos internals, so don't really know where she'll expansion would play a role in making this work. My understanding is that the docker executor does in fact have these environment variables defined, however, they are not passed to the docker container (using the -e flag) when it is started. So wouldn't it just be a matter of reading the environment variables in the docker executor and generating the appropriate -e flags to pass to docker? The variables could be prefixed or suffixes to ensure that passing them down doesn't cause unintended behavior in the container. E.g. AGENT_ENV_LIBPROCESS_IP, AGENT_ENV_MESOS_AGENT_ENDPOINT Then the container startup script needs to re define them with the appropriate name.

Re: Set LIBPROCESS_IP for frameworks launched with marathon
Tom, We’ve discussed the ‘plucking’ earlier. It would be desired to move away from having to set a file on the agent. Think - DC/OS. As a user, you may have no chance to access the filesystem. I get that the order might be not what the user would expect. Hence I’d be more towards the latter option. Always passing the LIBRPOCESS_IP into the container. I’d argue that, by default, it should not carry the name of the var over. It should be avaialble under another name but giving the user the option to assign it to LIBPROCESS_IP inside of the container. – Best regards, Radek Gruchalski ra...@gruchalski.com de.linkedin.com/in/radgruchalski *Confidentiality:*This communication is intended for the above-named person and may be confidential and/or legally privileged.

Say you have 1 master and 2 agents with these IPs:

- mesos-agent-0: 10.100.1.11
- mesos-agent-1: 10.100.1.12
Your problem is that you have no way to obtain an IP address of the

One way to overcome this problem is to create a shell file, say in
/etc/mesos-agent.sh, with contents like:
...
AGENT_IP=10.100.1.11
…
If you’re using Marathon, you can copy that file to the sandbox
using docker volumes:
{
"containerPath":
“/etc/mesos-agent.sh",
"hostPath":
"/etc/mesos-agent.sh",
"mode": "RO"
}
You can now source
that in the container to set the LIBPROCESS_ADVERTISE_IP.
Other applications
simply use the mesos-agent-X host name. That’s without
mesos-dns.
Things are easier
with mesos-dns or consul service catalog (I prefer the
latter).

LIBPROCESS_HOST=$HOST to be make the framework take the proper IP - you are
describing a different problem.

Re: Set LIBPROCESS_IP for frameworks launched with marathon
Thanks Radoslaw. I'm not really set on using host names, I just want a reliable
way to start the framework. For the meantime I have gone with a solution
similar to what you suggested. We use /etc/default/mesos file to configure
mesos, and it has the ip defined, so I just mounted that in the container and
read the ip.
I would like to avoid having a dependency on the file system of the agents
though. I'm not sure why I can't have the docket executor set the LIBPROCESS_IP
variable in the same way the command executor does.
Thanks

Re: Set LIBPROCESS_IP for frameworks launched with marathon
Out of curiosity. Why are you insisting on using host names?
Say you have 1 master and 2 agents with these IPs:
- mesos-master-0: 10.100.1.10
- mesos-agent-0: 10.100.1.11
- mesos-agent-1: 10.100.1.12
Your problem is that you have no way to obtain an IP address of the agent
in the container. Correct?
One way to overcome this problem is to create a shell file, say in
/etc/mesos-agent.sh, with contents like:
...
AGENT_IP=10.100.1.11
…
If you’re using Marathon, you can copy that file to the sandbox using
docker volumes:
{
"containerPath": “/etc/mesos-agent.sh",
"hostPath": "/etc/mesos-agent.sh",
"mode": "RO"
}
You can now source that in the container to set the LIBPROCESS_ADVERTISE_IP.
Other applications simply use the mesos-agent-X host name. That’s without
mesos-dns.
Things are easier with mesos-dns or consul service catalog (I prefer the
latter).

My understanding is that the scheduler uses LIBPROCESS_IP to determine
which network interface to bind to, and also which ip to advertise to the
master, so that the master can send offers. There is also another variable
LIBPROCESS_ADVERTISE_IP. If this is defined then LIBPROCESS_IP is used to

It would be great if there was a LIBPROCESS_ADVERTISE_HOST variable, then I
could just use the $HOST variable to define this.

Re: Set LIBPROCESS_IP for frameworks launched with marathon
The issue refers to LIBPROCESS_IP not LIBPROCESS_HOST. I haven’t been able to find the LIBPROCESS_HOST variable documented anywhere. My understanding is that the scheduler uses LIBPROCESS_IP to determine which network interface to bind to, and also which ip to advertise to the master, so that the master can send offers. There is also another variable LIBPROCESS_ADVERTISE_IP. If this is defined then LIBPROCESS_IP is used to determine which network interface to bind to, and LIBPROCESS_ADVERTISE_IP is used to determine which ip to advertise to the master. It would be great if there was a LIBPROCESS_ADVERTISE_HOST variable, then I could just use the $HOST variable to define this. > On 5 Jun 2016, at 10:41 pm, Sivaram Kannan <sivara...@gmail.com> wrote: > > > I have been using this way from 0.23.0 to the 0.28.0.

Re: Set LIBPROCESS_IP for frameworks launched with marathon
Hmmm… that doesn’t seem to work for me. What version of mesos does this work in? I am running 0.27.1. When using this approach, I still get the following error when the kafka mess framework is starting up. "Scheduler driver bound to loopback interface! Cannot communicate with remote master(s). You might want to set 'LIBPROCESS_IP' environment variable to use a routable IP address.” I tried setting LIBPROCESS_IP to ‘0.0.0.0’ and LIBPROCESS_ADVERTISE_IP=‘the public ip’ and this works. But the host variations don’t seem to work. (i.e. set LIBPROCESS_IP=0.0.0.0 and LIBPROCESS_ADVERTISE_HOST=$HOST) It seems lib process doesn’t support using host names. I think I might have to run the framework outside of docker, but I would really like to avoid this. This problem would be solved if the docker executor was able to set the same environment variables as the command executor. Is there a way to make this happen? I saw that mesos can be extended with a Hook ‘module’ to set extra environment variables in docker containers. This might be a solution, but seems over wrought for a simple problem. > On 5 Jun 2016, at 12:50 am, Sivaram Kannan <sivara...@gmail.com> wrote: > > > Hi, > > Can you try adding && after the LIBPROCESS_HOST variable and the actual > command.

Re: Set LIBPROCESS_IP for frameworks launched with marathon
Hi @haosdent
Based on my testing, this is not the case.
I ran a task (from marathon) without using a docker container that just printed
out all environment variables. i.e. while [ true ]; do env; sleep 2; done
I then run a task that executed the same command inside an alpine docker image.
When running without a docker image LIBPROCESS_IP was defined along with many
other variables.
Sample output when running without docker (note LIBPROCESS_IP) is defined

Re: Set LIBPROCESS_IP for frameworks launched with marathon
The reason I need to set LIBPROCESS_IP is because the slaves have 2 network
interfaces, and the docker container is running in host networking mode. So
libmesos doesn’t know which IP to advertise. The hostnames of the slaves are
all resolvable.
I have noticed that if I run a marathon app that doesn’t use docker, e.g. while
[ true ]; do env; sleep 2; done, that LIBPROCESS_IP is defined in the
environment. However, when running a docker image this variable is not defined.
Is there a way to have marathon pass along all environment variables defined by
mesos?
Thanks

Re: Set LIBPROCESS_IP for frameworks launched with marathon
Hello,
Can you try changing your cmd to:
"LIBPROCESS_IP=$HOST ./kafka-mesos.sh scheduler --master=mesos-master:5050
--zk=mesos-master:2181 --api=http://$HOST: <http://mesos-slave0:/>
--storage=zk://kafka-mesos"
and remove constraints and env sections.

Re: Set LIBPROCESS_IP for frameworks launched with marathon
@haosdent I’m not sure how this works internally, but it seems the mess master
needs to send requests to the framework for resource offers, and therefore
needs to know the external IP (i.e. the host IP)
@craig w
Would I need to do this in the cmd portion of the marathon JSON? I currently
have the config below
{
"container": ...,
"id":"kafka-mesos-scheduler",
"cpus": 0.5,
"mem": 256,
"ports": [],
"cmd": "./kafka-mesos.sh scheduler --master=mesos-master:5050
--zk=mesos-master:2181 --api=http://mesos-slave0:
--storage=zk:/kafka-mesos",
"instances": 1,
"constraints": [["hostname", "LIKE", "mesos-slave0"]],
"env": {
"LIBPROCESS_IP": "192.168.3.16"
}
}
@Chris Baker Currently we don’t have mess-dns setup but if this works it would
seem to be a nice solution. However, I did try setting LIBPROCESS_IP to the
slave hostname and it seems to produce a parse error. So I think it needs to be
an actual IP address.
I was hoping there would be a configuration for the slave that would
automatically populate this env variable when starting the docker container. So
I don’t need to complicate the marathon file, and can reuse it in different
clusters.

Re: Set LIBPROCESS_IP for frameworks launched with marathon
Alternatively, because the $HOST username is indirect, which would require a runtime element to "export $LIBPROCESS_IP=$HOST", another alternative is to fallback on Mesos-DNS, if that's part of the cluster deployment, setting $LIBPROCESS_IP to the (a priori) Mesos-DNS entry corresponding to the service.
