Easy way to update `mesos-slave` attributes? about panteras HOT 5 CLOSED

Unfortunately there is no easy way to do that.
One way is to edit /etc/supervisord.conf and run supervisorctl reread or reload (but reload can restart apps)

about this escaping. how about using ' single quotes instead of \\\\\" ?

from panteras.

Actually, I do something like:

ROLES_COMBINED="compute:truelog:true" # fed from somewhere else
MESOS_SLAVE_PARAMS="--attributes=\\\\\"${ROLES_COMBINED}\\\\\" --resources=\\\\\"ports(*):[8000-9999, 31000-32999]\\\\\""

In this case I cannot use the single quotes ' since ${ROLES_COMBINED} would not be replaced anymore...

hmm I have just check it and it works for me:

# ROLES_COMBINED="compute:truelog:true"
# MESOS_SLAVE_PARAMS="--attributes='${ROLES_COMBINED}' --resources='ports(*):[8000-9999, 31000-32999]'"
# echo $MESOS_SLAVE_PARAMS
--attributes='compute:truelog:true' --resources='ports(*):[8000-9999, 31000-32999]'

Is it working for you ?

Oh, haven't got the time to test that out; but since this is working for me as it is right now, no pressure on changing it... I will consider it next time I need to touch that file/mechanism...

we can close this for now, since there doesn't seem to be an easy and nice way to adjust the mesos attributes for a running mesos slave...
