  • v1.11.0

    ๐Ÿš€ This release contains the following highlights:

    • Mesos Containerizer now supports using pre-provisioned external CSI storage volumes by means of the new volume/csi isolator; the latter significantly extends the range of compatible 3rd party CSI plugins compared to the already existing SLRP-based solution (MESOS-10141).

    • The Scheduler API adds an interface allowing frameworks to put constraints on agent attributes in resource offers to help "picky" frameworks significantly reduce scheduling latency when close to being out of quota (MESOS-10161).

    • The CMake build becomes usable for deploying in production (MESOS-898).

    โž• Additional API Changes:

    • Breaking change Deprecated authentication credential text format support.

    • [MESOS-10194] - Mesos master failure "Check failed: 'get_(role)' Must be SOME"

    • ๐Ÿš€ This is a bug fix release.

    • [MESOS-9609] - Master check failure when marking agent unreachable.

  • v1.10.0

    May 28, 2020

    ๐Ÿš€ This release contains the following highlights:

    • Container resource bursting has been supported on Linux. Frameworks are now able to specify CPU and memory limits for tasks (separately from resource requests) and also the level of isolation they desire when launching task groups - CPU and memory may be isolated at the executor container level, or the task container level (MESOS-10001).

    • Executors can now use a Unix domain socket to connect to an agent, instead of connecting via TCP (MESOS-10034).

    • Existing reservations can now be modified via the RESERVE_RESOURCES master API call (MESOS-9981).

    • Performance of read-only V1 operator API calls has been improved by introducing direct serialization into JSON/protobuf and extending the batching mechanism to parallel processing of these calls by the master (similarly to /state endpoint). This brings V1 operator API performance on par with older HTTP endpoints (MESOS-10026, MESOS-9497).

    • Breaking change for authorizer modules: authorizers are now required to implement a method for returning ObjectApprovers that are valid throughout all of their lifetime. For framework and operator API subscriber principals the set of ObjectAprovers is now requested from the authorizer only once per subscription (MESOS-10056, MESOS-10057).

    โž• Additional API Changes:

    • Quota can now be set on the default * role.
    • Quota consumption metrics are now exposed by the allocator.

    ๐Ÿš‘ Unresolved Critical Issues:

    • [MESOS-10066] - mesos-docker-executor process dies when agent stops. Recovery fails when agent returns
    • [MESOS-10011] - Operation feedback with stale agent ID crashes the master

  • v1.9.0

    September 05, 2019

    ๐Ÿš€ This release contains the following highlights:

    • Maintenance:

      • Added new APIs to support automatic node draining via operator APIs. This serves as an alternative to framework-assisted draining using maintenance primitives. (MESOS-9753)
    • Resource Management:

      • Support for quota limits has been added. The existing quota guarantees are deprecated in favor of using limits (and in the future, priorities).
    • Security

      • A new libprocess flag --hostname_validation_scheme has been added. This allows users to enable a new RFC 6125-compliant hostname verification scheme based on primitives provided by OpenSSL. This will also improve performance by getting rid of all reverse DNS lookups. (MESOS-9784)
      • The use of anonymous cipher suites is now disallowed when TLS certificate verification is enabled. (MESOS-9810)
    • Containerization:

      • A new --docker_ignore_runtime flag has been added. This causes the agent to ignore any runtime configuration present in Docker images. (MESOS-9760)
      • Add no-new-privileges isolator. A new Linux isolator has been added to support enabling the no_new_privs process control flag. (MESOS-9770)
      • The Mesos containerizer now masks sensitive paths in /proc for containers that do not share the host's PID namespace. (MESOS-9771)
      • The Mesos containerizer now supports configurable IPC namespace and /dev/shm. Container can be configured to have a private IPC namespace and /dev/shm or share them from its parent, and the size of its private /dev/shm is also configurable. (MESOS-9795)
      • The Mesos containerizer now includes ephemeral overlayfs storage in the task disk quota as well as sandbox storage. (MESOS-9900)
      • A new /containerizer/debug HTTP endpoint has been added. This endpoint exposes debug information for the Mesos containerizer. At the moment, it returns a list of pending operations related to Isolators and Launchers. (MESOS-9756)

    โž• Additional API Changes:

    • Mesos components will now forego TLS certificate validation for incoming connections, unless LIBPROCESS_SSL_REQUIRE_CERT is set to true.

    • The Socket::connect(const Address&) member function will now abort the program when called on a LibeventSSLSocket. Instead, the new overload Socket::connect(const Address&, const TLSClientConfig&) must be used.

      NOTE: This new overload is only available when libprocess is compiled with --enable-ssl.

    Unresolved Critical Issues:

    • MESOS-9889 - Master CPU high due to unexpected foreachkey behaviour in Master::__reregisterSlave
    • MESOS-9697 - Release RPMs are not uploaded to bintray
    • MESOS-9579 - ExecutorHttpApiTest.HeartbeatCalls is flaky.
    • MESOS-9536 - Nested container launched with non-root user may not be able to write to its sandbox via the environment variable MESOS_SANDBOX
    • MESOS-9520 - IOTest.Read hangs on Windows
    • MESOS-9500 - spark submit with docker image on mesos cluster fails.
