Benno Evers created MESOS-10035:
-----------------------------------
Summary: Implement `enable_http_executor_domain_sockets` agent flag
Key: MESOS-10035
URL: https://issues.apache.org/jira/browse/MESOS-10035
Project: Mesos
Issue Type: Task
Reporter: Benno Evers
Based on the design in
https://docs.google.com/document/d/1RUvjoBvM3UX_lLcq_J_crWpMMn3nO8CY0KWc655ELsM/edit
we need:
* A `--enable_http_executor_domain_sockets[=true|false]` flag
* An `optional StringValue mesos_socket_location` field in the `ContainerInfo`
protobuf
(note: the last one is still under discussion and has a high chance of being
dropped from the final design, so ideally the commits will be structured such
that it can easily be dropped from the code as well)
The basic functionality we'd like for this task is, in pseudocode:
{noformat}
DURING task launch
IF launching new executor && enable_http_executor_domain_sockets == True &&
!domain sockets disabled for this executor:
Inject MESOS_DOMAIN_SOCKET environment variable pointing to `<executor
root>/agent.sock` or `mesos_socket_location` into the executor environment.
{noformat}
The code that actually creates the socket and puts it into the location pointed
to by `MESOS_DOMAIN_SOCKET` will be implemented in a separate ticket.
