Simone Gotti bec9476d6c runservice: store related runid with logs and archives
Logs and archives can be shared by multiple runs. So removing a run doesn't
imply that we could also remote the logs and archives since they could be
"referenced" by another run.

Store also the runids as specific objects along with the logs and archives so,
we'll remove them only when no runids objects exist.

Simone Gotti 1e34dca95d runservice: split and simplify scheduler and executor naming
Also if they are logically part of the runservice the names runserviceExecutor
and runserviceScheduler are long and quite confusing for an external user

Simplify them separating both the code parts and updating the names:

runserviceScheduler -> runservice
runserviceExecutor -> executor

Simone Gotti e4e7de4ad2 runservice/gateway: return run on run action 2019-05-07 23:23:58 +02:00
Simone Gotti afae185e11 *: rework run approval and annotations
* runservice: use generic task annotations instead of approval annotations
* runservice: add method to set task annotations

* gateway: when an user call the run task approval action, it will set in the
task annotations the approval users ids. The task won't be approved.

* scheduler: when the number of approvers meets the required minimum number
(currently 1) call the runservice to approve the task

In this way we could easily implement some approval features like requiring a
minimum number of approvers (saved in the task annotations) before marking the
run as approved in the runservice.

Simone Gotti cb78ea48bc runservice: rename command(handler) to action(handler)
Since we're going to migrate all actions (also queries that now are implemented
in the api handlers) there

Simone Gotti bad18bf814 *: report objects size for objectstorage.WriteObject 2019-05-02 09:49:55 +02:00
Simone Gotti 34cfdfeb3b objectstorage: add size option to WriteObject
On s3 limit the max object size to 1GiB when the size is not provided (-1) or
the minio client will calculate a big part size since it tries to use the
maximum object size (5TiB) and will allocate a very big buffer in ram. Also
leave as commented out the previous hack that was firstly creating the file
locally to calculate the size and then put it (for future reference).

Simone Gotti e964aa3537 objectstorage: add persist option to WriteObject
This options is a noop on s3 but on the posix implementation it becomes useful
when there isn't the need to have a persistent file, thus avoiding some fsync
calls.

Simone Gotti 2c3e6bf9e4 wal: update and rename to datamanager
* Rename to datamanager since it handles a complete "database" backed by an
objectstorage and etcd

* Don't write every single entry as a single file but group them in a single
file. In future improve this to split the data in multiple files of a max size.

Simone Gotti 41e333d7ec *: rename "lts" to "ost"
`lts` was choosen to reflect a "long term storage" but currently it's just an
object storage implementation. So use this term and "ost" as its abbreviation
(to not clash with "os").

Simone Gotti 6f88bd3d53 runservice: handle multiple executor archs
An executor can handle multiple archs (an executor that talks with a k8s cluster
with multi arch nodes). Don't use a label for archs but a custom executor
field.

Simone Gotti a0d69f4bc3 runservice executor: update for executor groups
* Add the concept of executor groups and siblings executors
* Add the concept of dynamic executor: an executor in an executor group that
doesn't need to be manually deleted from the scheduler since the other sibling
executors will take care of cleaning up its pods.
* Remove external labels visibility from pod.
* Add functions to return the sibling executors and the executor group
* Delete pods of disappeared sibling executors

Simone Gotti 9f89a923c0 runservice scheduler: take a copy of run in advanceRunTasks
take and change a copy of the current run so we'll change newRun and use curRun
status for logic decision. In this way result are reproducible or they will be
affected by the random run.Tasks map iteration order.

Simone Gotti da27348a1d runservice: implement run setup errors
Add the ability to define a run with a setuperror phase.

When the run setup has errors client could submit a run with a list of setup
errors. In such case the run will be created in the setuperror phase.

Setup errors are currently generated by the webhook receiver and the run service
when it checks the run config for possible issues.

Simone Gotti 671b89d391 runservice: merge RunConfig and RunData
* Use just RunConfig
* Use StaticEnvironment vs Environment in RunConfig to distinguish between env
that won't change at run recreation from env that could change at every
recreation
* The RunCreate api will just receive the runtasks instead of a runconfig (more
right)

Simone Gotti 3642be6f21 */api: Use helpers for error handling
* client: always parse the json error message field and return its contents
* Use ErrBadRequest and ErrNotFound in every handler and command
* Gateway: by default pass underlying service error (configstore, runservice) to
client keeping the status code and message. In future, if some errors must be
masked, we should change the specific parts that need special handling.

Simone Gotti 643dfe4072 runservice api: improve response handling
* Command: use ErrBadRequest
* Always return a json message also on error. For internal errors return a
generic "internal server error" message to not leak the real internal error to
clients
* Return 201 Created on resource creation
* Return 204 No Content on resource deletion and other action with no json
output
