This is maybe a more realistic job that someone would actually submit
via the API; it more closely aligns with the example job from `nomad
job init`.
It's also been updated to use group network and service definitions.
In a deployment with two groups (ex. A and B), if group A's canary becomes
healthy before group B's, the deadline for the overall deployment will be set
to that of group A. When the deployment is promoted, if group A is done it
will not contribute to the next deadline cutoff. Group B's old deadline will
be used instead, which will be in the past and immediately trigger a
deployment progress failure. Reset the progress deadline when the job is
promotion to avoid this bug, and to better conform with implicit user
expectations around how the progress deadline should interact with promotions.
HCL2 locals don't have type constraints, and the map syntax is interpreted as
an object. So users may need to explictly convert to map for some functions.
The `convert` function documentation was missing the required type constructor
parameter for collections.
Block labels are not expressions so they can't be interpolated without hacks
like `dynamic` blocks. Clarify this so that we don't confuse users who
shouldn't need to dig into the subtle nuances between expressions and blocks.
Using the environment variable stopped working here a while back,
should be using the port label. Also upgrade to uuid-api:v5 which
supports linux/arm64.
This PR enables jobs configured with a custom sidecar_task to make
use of the `service.expose` feature for creating checks on services
in the service mesh. Before we would check that sidecar_task had not
been set (indicating that something other than envoy may be in use,
which would not support envoy's expose feature). However Consul has
not added support for anything other than envoy and probably never
will, so having the restriction in place seems like an unnecessary
hindrance. If Consul ever does support something other than Envoy,
they will likely find a way to provide the expose feature anyway.
Fixes#9854
This PR adds pid_mode and ipc_mode options to the exec and java task
driver config options. By default these will defer to the default_pid_mode
and default_ipc_mode agent plugin options created in #9969. Setting
these values to "host" mode disables isolation for the task. Doing so
is not recommended, but may be necessary to support legacy job configurations.
Closes#9970
Allow for readiness type checks by configuring nomad to ignore warnings
or errors reported by a service check. This allows the deployment to
progress and while Consul handles introducing the sercive into a
resource pool once the check passes.
This PR adds default_pid_mode and default_ipc_mode options to the exec and java
task drivers. By default these will default to "private" mode, enabling PID and
IPC isolation for tasks. Setting them to "host" mode disables isolation. Doing
so is not recommended, but may be necessary to support legacy job configurations.
Closes#9969
