* Add a generic container volume option that currently only support tmpfs. In
future it could be expanded to use of host volumes or other kind of volumes (if
supported by the underlying executor)
* Implement creation of tmpfs volumes in docker and k8s drivers.
Reorganize ExecutorTask to better distinguish between the task Spec and
the Status.
Split the task Spec in a sub part called ExecutorTaskSpecData that contains
tasks data that don't have to be saved in etcd because it contains data that can
be very big and can be generated starting from the run and the runconfig.
Currently, if no shell is defined in the task and in the step, the executor will
use an hardcoded default shell.
This will cause changed run behavior if we add an option to globally set the
agola default shell.
To avoid this set the task shell to the default shell inside the runconfig if
it's empty so future executions will always use this value.
Defining an option to override the user for a run step is too much fine grained
and, for consistency, will require to do the same also for the other steps
(clone, *workspace etc...).
Remove it since it's probably enough to define it at the task level.
In c1ff28ef9f we exported various types. Unfortunately the types used by cmd
variable create/update are the wrong types and marshalling fails. Fix it using
the right type. In future this internal types should be exported.
Since the current logic is to use the first available private ip address as the
advertized address we have to listen on wildcard since a different host provided
in web.ListenAddress will make the executor unreachable.
In future improve this to let the user to manually define the bind and the
advertized address (perhaps using go-sockaddr templates like done by consul) to
also support nat between the schedulers and the executors.
Older version of docker doesn't support the exec api Env and WorkingDir options.
Support these versions by doing the same we already do with the k8s driver: use
the `toolbox exec` command that will set the provided Env, change the cwd to the
WorkingDir and the exec the wanted command.
Export clients and related packages.
The main rule is to not import internal packages from exported packages.
The gateway client and related types are totally decoupled from the gateway
service (not shared types between the client and the server).
Instead the configstore and the runservice client currently share many types
that are now exported (decoupling them will require that a lot of types must be
duplicated and the need of functions to convert between them, this will be done
in future when the APIs will be declared as stable).
There was a typo so we weren't setting the task endTime when the setup step
failed.
Also unify all logic to just use `et` (instead of a mix of `et` or `rt.et`)
Before kubernetes 1.14 nodes were labeled with the "beta.kubernetes.io/arch"
label instead of the "kubernetes.io/arch".
Current k8s version (v1.15) labels nodes with both labels but it's
deprecated and will removed in future versions.
At driver start get the current k8s api version and choose the right label to
use as node selector based on it.
* add a config option allowPrivilegedContainers
* fail task setup if privileged containers are requested but they aren't
allowed.
* report if privileged containers are allowed to the runservice
* don't remove the runningTask when executeTask finishes but just mark the
runningTask a not executing
* add a loop to periodically update executorTask status and remove the
runningTask if not executing and status update was successful
* remove runningTask when it disappears from the runservice
Just a raw replace of "github.com/pkg/errors".
Next steps will improve errors (like remote errors, api errors, not exist errors
etc...) to leverage its functionalities
This was already defined in the config but not implemented in the executor and
drivers.
All the containers defined in the runtime after the first one will be "service"
containers. They will share the same network namespace with the other containers
in the "pod" so they can communicate between themself on loopback
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
