Hi all,
Please vote on releasing the following candidate as Apache Mesos 1.1.0.
1.1.0 includes the following:
--------------------------------------------------------------------------------
* [MESOS-2449] - **Experimental** support for launching a group of tasks
via a new `LAUNCH_GROUP` Offer operation. Mesos will guarantee that either
all tasks or none of the tasks in the group are delivered to the executor.
Executors receive the task group via a new `LAUNCH_GROUP` event.
* [MESOS-2533] - **Experimental** support for HTTP and HTTPS health checks.
Executors may now use the updated `HealthCheck` protobuf to implement
HTTP(S) health checks. Both default executors (command and docker) leverage
`curl` binary for sending HTTP(S) requests and connect to `127.0.0.1`,
hence a task must listen on all interfaces. On Linux, For BRIDGE and USER
modes, docker executor enters the task's network namespace.
* [MESOS-3421] - **Experimental** Support sharing of resources across
containers. Currently persistent volumes are the only resources allowed to
be shared.
* [MESOS-3567] - **Experimental** support for TCP health checks. Executors
may now use the updated `HealthCheck` protobuf to implement TCP health
checks. Both default executors (command and docker) connect to `127.0.0.1`,
hence a task must listen on all interfaces. On Linux, For BRIDGE and USER
modes, docker executor enters the task's network namespace.
* [MESOS-4324] - Allow access to persistent volumes as read-only or read-write
by tasks. Mesos doesn't allow persistent volumes to be created as read-only
but in 1.1 it starts allow tasks to use the volumes as read-only. This is
mainly motivated by shared persistent volumes but applies to regular
persistent volumes as well.
* [MESOS-5275] - **Experimental** support for linux capabilities. Frameworks
or operators now have fine-grained control over the capabilities that a
container may have. This allows a container to run as root, but not have all
the privileges associated with the root user (e.g., CAP_SYS_ADMIN).
* [MESOS-5344] -- **Experimental** support for partition-aware Mesos
frameworks. In previous Mesos releases, when an agent is partitioned from
the master and then reregisters with the cluster, all tasks running on the
agent are terminated and the agent is shutdown. In Mesos 1.1, partitioned
agents will no longer be shutdown when they reregister with the master. By
default, tasks running on such agents will still be killed (for backward
compatibility); however, frameworks can opt-in to the new PARTITION_AWARE
capability. If they do this, their tasks will not be killed when a partition
is healed. This allows frameworks to define their own policies for how to
handle partitioned tasks. Enabling the PARTITION_AWARE capability also
introduces a new set of task states: TASK_UNREACHABLE, TASK_DROPPED,
TASK_GONE, TASK_GONE_BY_OPERATOR, and TASK_UNKNOWN. These new states are
intended to eventually replace the TASK_LOST state.
* [MESOS-6077] - **Experimental** A new default executor is introduced which
frameworks can use to launch task groups as nested containers. All the
nested containers share resources likes cpu, memory, network and volumes.
* [MESOS-6014] - **Experimental** A new port-mapper CNI plugin, the
`mesos-cni-port-mapper` has been introduced. For Mesos containers, with the
CNI port-mapper plugin, users can now expose container ports through host
ports using DNAT. This is especially useful when Mesos containers are
attached to isolated CNI networks such as private bridge networks, and the
services running in the container needs to be exposed outside these
isolated networks.
