need help http api /endpoints
I would be really glad if you could tell me what to do for the following situation; I am running a job consists of tasks running in docker containers on agents. One of these tasks is the job master, which decides when to kill the framework or kill few of the tasks or add new tasks to the job. I can kill the framework using the endpoint mesos.apache.org/documentation/latest/endpoints/master/teardown<http://mesos.apache.org/documentation/latest/endpoints/master/teardown/>. What should I do in order to add or kill tasks. As I mentioned one of the tasks(job master) will decide on this dynamically.
Thanks,
Gurhan

There is no operator API (i.e., http api endpoint in your parlance) to
add/kill tasks.
Your job master can talk to the framework that launched all your tasks in
the first place (marathon?), to add/kill tasks. Most existing mesos
frameworks expose add/kill tasks through their own API.
Alternatively, you can rewrite your job master as a Mesos framework
<http://mesos.apache.org/documentation/latest/app-framework-development-guide/>.
A framework can add/kill tasks through the scheduler api
<http://mesos.apache.org/documentation/latest/scheduler-http-api/>. But,
this is likely a much bigger undertaking.
