# Changelog

## [1.2.0.rc2](https://github.com/kontena/kontena/releases/tag/v1.2.0.rc2) (2017-04-13)

### Highlights

#### Experimental volumes support
The Kontena 1.2 release introduces [experimental support for volume management](https://github.com/kontena/kontena/blob/v1.2/docs/using-kontena/volumes.md).
Stack services can now [use](https://github.com/kontena/kontena/blob/v1.2/docs/references/kontena-yml.md#volumes) volumes created by `kontena volume create`, and the service and volume instances will be scheduled together.

Kontena volumes can use by volume drivers provided by Docker plugins installed on the host nodes, such as [rexray](https://rexray.codedellemc.com/).

#### Native IPsec overlay network encryption

Host nodes will be upgraded to Weave 1.9.3, and switch to using the new IPSec [encrypted datapath](https://github.com/kontena/kontena/blob/v1.2/docs/core-concepts/networking.md#encrypted-datapath) for the overlay networking between host nodes.

The new encrypted datapath uses native Linux IPsec encryption, providing improved performance compared to the current [userspace `sleeve`](https://github.com/kontena/kontena/blob/v1.2/docs/core-concepts/networking.md#sleeve) transport.
Host nodes will fall back to the current UDP-based `sleeve` transport if they are unable to send or receive IPsec ESP packets. Note that the default firewall rules for e.g. Google Cloud Platform deny IPsec ESP packets by default.

#### Improved service deployment and agent communication

The server and agent have been improved to be more robust in the case of various error and overload situations affecting service deployments.
The agent can now recover from various errors, healing itself and resolving any deployment inconsistencies.

The `kontena service deploy` command now provide better reporting of deployment status and errors. Pending CLI `kontena stack deploy` support for service deploy progress and errors (#2114).

#### Kontena Cloud metrics and real-time events

TODO: something to link to here

#### CLI

* [`kontena grid create --subnet --supernet`](https://github.com/kontena/kontena/blob/v1.2/docs/using-kontena/grids.md#grid-subnet-supernet)

    If the default `10.80.0.0/12` internal overlay network address space overlaps with the the private networking address space on the host node provider, you can chose a different internal overlay networking address space for use by the Kontena host nodes and service containers.

* [`kontena grid update --log-forwarder fluentd`](https://github.com/kontena/kontena/blob/v1.2/docs/using-kontena/grids.md#logging-options)

    The agent can ship service container logs to an external `fluentd` server.

* `kontena grid events`, `kontena stack events`, `kontena service events`

    Follow scheduling and deployment related-events across the Kontena master and node agents.

* `kontena stack {build,install,upgrade,validate} --values-to --values-from`

    Automate [Kontena stack variables](https://github.com/kontena/kontena/blob/v1.2/docs/references/kontena-yml-variables.md) across deployments.

* `kontena stack validate --online`

    Stack validation happens offline by default, avoiding any side-effects such as Kontena Vault writes.

* `kontena stack upgrade --force`

    Require confirmation if upgrading a different stack file.

* `kontena service show`

   List containers by instance.

* `kontena service rm --instance`

   Force a service instance to be rescheduled.

* `kontena node ssh --any`

    SSH to the first available connected node.

* `kontena node rm`

    Refuse to remove a node that is still online.

* `kontena master user`

    Renamed and deprecated `kontena master users`.

* `kontena volume create`, `show`, `remove`, `list`

    See the [Volumes](https://github.com/kontena/kontena/blob/v1.2/docs/using-kontena/volumes.md) documentation.

#### Stacks

* Support named `service: volumes: - volume:/path`

    All named service volumes must now be defined in the `volumes` section.

* New `volumes` section

    See the [Kontena stack volume](https://github.com/kontena/kontena/blob/v1.2/docs/references/kontena-yml.md#volumes) documentation.

### Known issues

* Service `*.kontena.local` DNS aliases missing after `kontena grid trusted-subnet` changes #2158

    Using the `kontena grid trusted-subnet add/remove` commands to re-configure weave, any `$service.$grid.kontena.local` and `$service.$stack.kontena.local` DNS aliases will get forgotten.

    Workaround is to `docker restart kontena-agent` on each host node to force service DNS aliases to be re-registered.

* Stack upgrade / Service update will not re-deploy service on removal of embedded objects (#2109)

    Removing hooks, links, secrets or volumes from a stack service will not re-deploy the service containers after a `kontena stack upgrade`. Use `kontena service deploy --force` to update the service container configuration.

### Fixed issues

* After weave upgrade, service aliases are missing from DNS #2079
* Agent should check that volume driver match before reusing it #2089
* Stack upgrade can remove linked-to services, breaking linking services #1769

## [1.2.0.rc1](https://github.com/kontena/kontena/releases/tag/v1.2.0.rc1) (2017-04-07)

### Known issues

* After weave upgrade, service aliases are missing from DNS (#2079)

    If `*.kontena.local` DNS aliases are missing after an upgrade, restart the `kotnena-agent`.

* Stack upgrade can remove linked-to services, breaking linking services (#1769)

    Do not remove services from a stack if any services still link to them.

* Stack upgrade / Service update will not re-deploy service on removal of embedded objects (#2109)

    Removing hooks, links, secrets or volumes from a stack service will not re-deploy the service containers after a `kontena stack upgrade`. Use `kontena service deploy --force` to update the service container configuration.
