DC/OS Marathon constraints hostname list

Question

When I want use

"constraints": [["hostname", "CLUSTER", "192.168.18.6(1|2)"]]

or

"constraints": [["hostname", "CLUSTER", "DCOS-S-0(1|2)"]] 

In Marathon app name "/zaslepki/4maxpl" has all the time Waiting status

So I try use attribute - I execute:

[root@DCOS-S-00 etc]# systemctl stop dcos-mesos-slave-public.service
[root@DCOS-S-00 etc]# mesos-slave --work_dir=/var/lib/mesos/slave --attributes=DC:DL01 --master=zk://192.168.18.51:2181,192.168.18.51:2181,192.168.18.53:2181/mesos

To remedy this do as follows:
Step 1: rm -f /var/lib/mesos/slave/meta/slaves/latest
        This ensures agent doesn't recover old live executors.
Step 2: Restart the agent.
[root@DCOS-S-00 etc]# rm -f /var/lib/mesos/slave/meta/slaves/latest
[root@DCOS-S-00 etc]# systemctl start dcos-mesos-slave-public.service

and I use in .json application configuration file

"constraints": [["DC", "CLUSTER", "DL01"]]

Status application is Waiting.....

This is my .json file aplication "/zaslepki/4maxpl"

}

What I do wrong? I find that same problem link but there problem was fixed by use

constraints: [["DC", "CLUSTER", "DL01"]]

Answer 1

You've got a clue in a log:

Invalid attribute key:value pair 'DL01'

Change your attribute to key:value pair e.g., DC:DL01 and it should work. Probably you will need to clean metadata directory because you are changing Agent configuration.

Cluster operator doesnt work with multiple values. You need to pass regular expression so your it should looks like this

"constraints": [["hostname", "LIKE", "192.168.18.6(1|2)"]]
