The tasklet passes the timeout for the script check into the task
driver's `Exec`, and its up to the task driver to enforce that via a
golang `context.WithDeadline`. In practice, this deadline is started
before the task driver starts setting up the execution
environment (because we need it to do things like timeout Docker API
calls).
Under even moderate load, the time it takes to set up the execution
context for the script check regularly exceeds a full second or
two. This can cause script checks to unexpected timeout or even never
execute if the context expires before the task driver ever gets a
chance to `execve`.
This changeset adds a notice to operators about setting script check
timeouts with plenty of padding and what to monitor for problems.
Creating a FAQ question to provide a home for additional context around
bootstrapping. Linking from API page to `default_server_config`
attribute. Added sample API response to to discuss "Updated: false"
Allow a `/v1/jobs?all_namespaces=true` to list all jobs across all
namespaces. The returned list is to contain a `Namespace` field
indicating the job namespace.
If ACL is enabled, the request token needs to be a management token or
have `namespace:list-jobs` capability on all existing namespaces.
The MVP for CSI in the 0.11.0 release of Nomad did not include support
for opaque volume parameters or volume context. This changeset adds
support for both.
This also moves args for ControllerValidateCapabilities into a struct.
The CSI plugin `ControllerValidateCapabilities` struct that we turn
into a CSI RPC is accumulating arguments, so moving it into a request
struct will reduce the churn of this internal API, make the plugin
code more readable, and make this method consistent with the other
plugin methods in that package.
CSI plugins can require credentials for some publishing and
unpublishing workflow RPCs. Secrets are configured at the time of
volume registration, stored in the volume struct, and then passed
around as an opaque map by Nomad to the plugins.
